This month’s theme: GLP-1, first coumpound with broad positive effects for longevity?

---

GLP-1 (glucagon-like peptide-1) is a hormone naturally produced in the intestines that helps regulate blood sugar levels, digestion, and appetite. It works by stimulating the pancreas to release insulin when blood sugar is high, while also reducing the release of glucagon, a hormone that raises blood sugar. Additionally, GLP-1 slows the rate at which food leaves the stomach, which helps prevent sudden spikes in blood sugar after eating and promotes a feeling of fullness. Medications that mimic GLP-1 are commonly used to treat type 2 diabetes and support weight management, and they are also being studied for potential benefits in heart health and metabolic aging.

Metabolic reprogramming

GLP-1 receptor agonists (GLP-1RAs) act far beyond glucose control, intersecting with several hallmarks of aging. They reduce chronic low-grade inflammation by lowering CRP and pro-inflammatory cytokines, improve insulin/IGF-1 signaling, enhance mitochondrial efficiency, and decrease oxidative stress. Preclinical studies show improved mitochondrial biogenesis and reduced cellular senescence markers in metabolic tissues. These pathways are central to geroscience because dysregulated nutrient sensing, mitochondrial dysfunction, and inflammaging drive multiple age-related diseases. By restoring metabolic flexibility and reducing lipotoxicity, GLP-1 therapies may function as metabolic reprogrammers, shifting physiology toward a lower biological age phenotype.

Obesity trends and public health

In the United States, adult obesity prevalence climbed almost continuously from the late 1970s through the 2010s, driven by an obesogenic food environment, sedentary lifestyles, and widening socioeconomic disparities. National Health and Nutrition Examination Survey (NHANES) data showed rates rising from roughly 30% in 1999–2000 to over 42% by 2017–2020, with severe obesity increasing even faster. However, the most recent national surveillance reports (2021–2023) suggest a possible plateau, and in certain age and income subgroups, a slight decline, occurring alongside the rapid adoption of GLP-1 receptor agonists for both diabetes and obesity treatment. Pharmacy and claims data indicate several-fold growth in prescriptions for semaglutide and tirzepatide during this period, with the highest uptake among middle-aged adults and those with private insurance.

Healthspan gains

Large outcome trials demonstrate that GLP-1RAs reduce major adverse cardiovascular events (MACE), even in non-diabetic individuals with obesity. The SELECT trial showed a 20% reduction in MACE with semaglutide in people with overweight/obesity and established CVD. In parallel, GLP-1 therapies improve non-alcoholic fatty liver disease (NAFLD/NASH) through weight-independent mechanisms, including reduced hepatic steatosis and inflammation. Benefits also extend to blood pressure, lipid profiles, and heart failure symptoms, suggesting multi-system healthspan effects rather than single-disease treatment.-

Fat loss vs. muscle preservation

While GLP-1 drugs produce substantial weight loss (≈10–15% with semaglutide), up to 25–40% of total weight lost can be lean mass if no countermeasures are taken. For longevity, preserving skeletal muscle is critical to avoid sarcopenia and frailty. Clinical guidance increasingly emphasizes high protein intake, resistance training, and progressive loading during GLP-1 therapy. Emerging data suggest that combining GLP-1 with structured exercise improves fat-to-lean loss ratio and functional outcomes, aligning weight reduction with healthspan goals rather than simple mass reduction.

Combination Longevity Therapies

GLP-1 drugs seem to generate largely positive effects, but are unlikely to be standalone gerotherapeutics but may serve as foundational metabolic platforms. Combining GLP-1 with exercise enhances mitochondrial function and cardiorespiratory fitness; pairing with metformin targets complementary nutrient-sensing pathways; future combinations with rapalogs or senolytics could address multiple hallmarks simultaneously. The geroscience model favors such stacked interventions to achieve additive or synergistic effects on healthspan and disease prevention. Clinical trials exploring multi-modal metabolic and anti-aging strategies are now a key frontier.

Semaglutide, liraglutide, dulaglutide, exenatide, albiglutide, and lixisenatide are all medications in the GLP-1 receptor agonist class, which are primarily used to improve blood sugar control in people with type 2 diabetes and, in some cases, to support chronic weight management. Across this medication class, common side effects include nausea, reduced appetite, and slowed stomach emptying, and all require medical supervision to ensure proper dosing and safety monitoring.

Commonly Prescribed GLP-1 Medications

• Semaglutide is one of the newer and more potent options and is available as both a once-weekly injection and a daily oral tablet; it is widely recognized for producing significant weight loss and cardiovascular benefits in addition to glucose control. 

 

• Liraglutide is an older GLP-1 medication given as a daily injection and has an extensive safety record, although it typically results in slightly less weight loss than semaglutide. 

 

• Dulaglutide is administered as a once-weekly injection and is popular because of its user-friendly auto-injector device and strong evidence for cardiovascular risk reduction, though its weight-loss effect is generally moderate. 

 

• Exenatide was one of the earliest GLP-1 receptor agonists and is available as either a twice-daily injection or a once-weekly extended-release formulation; it remains effective for blood sugar management but is often considered less potent for weight reduction than newer medications. 

 

• Albiglutide is another once-weekly GLP-1 agent that was previously used for diabetes treatment but has been withdrawn from many markets and is no longer commonly prescribed. 

 

• Lixisenatide is a daily injection mainly used for type 2 diabetes, particularly effective at controlling blood sugar spikes after meals, although it generally produces less weight loss than newer GLP-1 drugs. 

 

This is the first drug to have potentially such a large positive effect in the majority of the population in the USA. However, it is because this population is overweight or obese. We also still have to see impact in the long term since the drugs are recent. Still, we have a global positive effect on healthy longevity.

The good news of the month- Latest pancreatic cancer research shows potential to shrink and eliminate tumors

---

A research team led by Mariano Barbacid at the Spanish National Cancer Research Centre (CNIO) has developed an experimental triple-combination therapy that completely eliminated pancreatic tumors in mice with no major side effects. The study, published in Proceedings of the National Academy of Sciences (PNAS), focuses on pancreatic ductal adenocarcinoma (PDAC), a highly aggressive cancer with a very low five-year survival rate. 

The therapy works by blocking three points in the KRAS signaling pathway, a gene mutation present in about 90% of pancreatic cancer cases. By targeting multiple points rather than a single one, the treatment prevented tumor resistance and produced long-lasting tumor regression in mouse models. The drug combination included an experimental KRAS inhibitor, an approved cancer drug, and a protein degrader. Although the results are very promising, researchers say more work is needed before clinical trials in humans can begin.

This month’s theme: Exosomes and Longevity

---

Exosomes are tiny membrane-bound vesicles released by cells that act as messengers between cells. Measuring about 30–150 nanometers, they form inside the cell and are released into body fluids such as blood and saliva. Exosomes carry proteins, lipids, and genetic material like RNA, which can influence the behavior of recipient cells by altering processes such as inflammation, immune responses, blood clotting, tissue repair, and aging. Because their contents reflect the state of the cells they come from, exosomes are important in research as biomarkers for disease and are being explored as potential therapeutic delivery vehicles.

Exosomes play an important role in the aging process by mediating the transfer of nucleic acids, lipids, and proteins between cells across a wide range of organisms. These vesicles exert significant gerontological effects, influencing cellular function and systemic aging. Exosomes derived from young or stem cells are enriched with antioxidant factors and anti-inflammatory cytokines that help counteract age-related cellular damage. Notably, conditions such as nutrient restriction stimulate exosome release, which has been shown to delay cellular senescence in vitro and slow aging processes in vivo. This effect is thought to occur through enhanced removal of damaged cellular components, including fragmented DNA, misfolded proteins, and oxidized biomolecules, in both animal models and humans. Collectively, these findings underscore the critical role of exosome-mediated waste clearance in aging biology and provide mechanistic support for the longevity benefits associated with fasting and metabolic stress, highlighting promising directions for future research into cellular maintenance and longevity interventions.

As a Longevity Therapy

Exosomes are rapidly emerging as one of the most exciting areas in longevity science. In recent years, researchers have discovered that many of the benefits associated with stem cell therapy are not due to the cells permanently integrating into tissues, but rather to the signals they release. These signals are largely carried by exosomes. This insight has shifted attention toward exosome-based therapies, which offer many of the regenerative benefits of stem cells without the complexity or risk associated with live cell transplantation.

Exosomes derived from mesenchymal stem cells (MSCs) are of particular interest in longevity research. They have also shown promise in areas such as skin rejuvenation, joint health, neuroprotection, and metabolic regulation. Because exosomes carry molecular “instructions” from their parent cells, they can influence aging pathways linked to cellular senescence, mitochondrial function, and repair mechanisms.

Another compelling aspect of exosomes is their potential role as biomarkers of aging. Their molecular cargo reflects the physiological state of the cells they originate from, making them valuable tools for monitoring biological aging and disease progression. At the same time, their natural stability and low immunogenicity make them attractive candidates for therapeutic delivery.

While exosome-based longevity therapies are still largely in the research, interest is rapidly growing. Clinical trials are underway, and exosome treatments are already being offered in some settings, though standardized protocols and long-term safety data are still needed. Ongoing research is focused on refining isolation techniques, improving quality control, and understanding how to best harness exosomes for targeted, personalized therapies.

As science continues to uncover how exosomes influence aging and regeneration, they are increasingly viewed as a key component of future longevity medicine—offering the possibility of extending not just lifespan, but healthspan.

Exosomes as a therapy for other diseases

In 2026, the exosome therapy landscape features over 70 active companies developing more than 80 pipeline therapies for regenerative medicine, oncology, and rare genetic diseases. Key companies leading the development of exosome-based therapeutics include:

 Capricor Therapeutics: A clinical-stage company using its StealthX platform for precision medicine. Its lead candidate, CAP-1002, is currently in advanced trials for Duchenne Muscular Dystrophy.

Aruna Bio: Uses neural-derived exosomes to cross the blood-brain barrier. It initiated Phase Ib/IIa clinical trials for AB126 in acute ischemic stroke in late 2024. 

ILIAS Biologics: Developed the EXPLOR platform for loading large therapeutic payloads. Its candidate ILB-202 completed Phase I trials for inflammatory conditions in 2023. EXO Biologics: A clinical-stage Belgian company that secured Series A funding in April 2024 to scale manufacturing and clinical supply for its therapeutic pipeline. 

Coya Therapeutics: Developing COYA 201, a therapy leveraging regulatory T-cell (Treg) derived exosomes for neurodegenerative and autoimmune diseases. 

NurExone Biologic: In early 2025, the company acquired a master cell bank to ensure a scalable supply for treating spinal cord and acute injuries. 

Brexogen: Evaluating BRE-AD01 for atopic dermatitis and BRE-MI01 for myocardial infarction. Direct Biologics: Known for ExoFlo, an intravenous exosome therapy used in clinical trials for severe respiratory conditions.

A recent study led by Nicolás Cherñavsky, a researcher working with Heales, looked at whether exosomes and other extracellular particles from young pigs can be safely injected into rats. The goal was to check if this kind of cross-species approach triggers any immediate immune or toxic reaction. Over nine days, the treated animals showed normal behavior, normal weight gain, and no signs of inflammation or organ damage. Detailed tissue analyses confirmed the absence of acute toxicity in the liver, kidneys, and spleen. These results add to the growing body of research suggesting that exosomes from young organisms may cross species barriers without causing short-term immune reactions. This is an encouraging step for future longevity and rejuvenation studies.

Scientific consensus increasingly aligns with the theory that exosomes function as powerful signaling vectors capable of activating internal self-repair mechanisms. These nano-sized vesicles carry a specialized “cargo” of proteins, lipids, and microRNAs (miRNAs) that act as “biological instructions” to reprogram recipient cells toward a more youthful functional state. Research into heterochronic parabiosis has demonstrated that exosomes from young sources—specifically young plasma or stem cells—can reverse age-related phenotypes at molecular, mitochondrial, and physiological levels. By delivering “youth signals” like miR-144-3p and miR-455-3p, these vesicles can significantly downregulate senescence markers such as p16 and p21, while simultaneously upregulating genes associated with telomerase activity and mitochondrial health, effectively telling the cell to resume the repair processes characteristic of early age.

The good news of the month- Mice living almost 5 years due to “telomere rivers”

---

Telomere Rivers—immune-derived particles that transfer rejuvenating signals between cells. Produced by CD4⁺ T cells, they deliver telomeric DNA and systemically, reversing aging independently of telomerase. Unlike plasma-based or cell-limited effects, Rivers act as a coordinated, immune-driven rejuvenation system, suggesting T cells play a central role in maintaining youth and enabling transferable, organism-wide rejuvenation.

If it is true, this is the most important longevity news in years. However, this is only a preprint and there are some problems in the information given. To be followed.

The Heales Journey: Celebrating 200 Editions of the Newsletter

---

Looking back on the first edition  

As we reach the 200th edition of Death of the Death, it is worth briefly returning to the very first newsletter published in January 2009. Issue number 0 introduced the ambition of following scientific progress related to human longevity, with a focus on the possibility of delaying, and potentially overcoming, age-related mortality.

The newsletter presented the concept of longevity escape velocity, the hypothesis that if advances in biomedicine increase life expectancy faster than time subtracts it, each generation of progress could enable the next. At the time, this idea was emerging in research circles, and the newsletter aimed to make it accessible and track developments in fields such as regeneration, stem cells and aging mechanisms.

Sixteen years later, this 200th issue marks continuity rather than conclusion. We know more, we live on average longer, but maximal lifespan did not extend. The same questions remain open, the same scientific domains continue to evolve, and the initial objective persists: documenting the progress, challenges and perspectives of longevity science over time.

For this newsletter, we give you 200 pieces of information about longevity and about our organization. They are regrouped into 16 categories. It is impossible to be complete and objective, but we tried.

The Powerhouse and the Clock: How Mitochondria Shape Aging

About 2,3 billion years ago, an organism absorbed a bacterium that would become mitochondria. This was, for animals, the most successful symbiosis in the history of life. Nowadays, mitochondria, often called the “powerhouses” of the cell, do far more than just produce energy. These small but mighty organelles generate ATP—the essential molecule that fuels nearly every cellular process—while also regulating calcium balance, apoptosis (programmed cell death), and key metabolic pathways. What makes them especially intriguing is that they contain their own DNA, separate from the cell’s nucleus, which makes them uniquely vulnerable to damage over time.

Mitochondria undergo wear and tear that affects their ability to function properly.

1. Damaged DNA, Damaged Cells

Mitochondria possess their own DNA (mtDNA), separate from the cell’s nuclear DNA. Unlike nuclear DNA, mtDNA lacks the robust protective histones and repair systems that guard against damage. This makes it particularly vulnerable to oxidative stress — the constant bombardment of reactive molecules produced during energy generation. Over time, oxidative stress introduces mutations into mtDNA, disrupting the genes responsible for key components of the electron transport chain. 

2. The ROS Paradox

Reactive oxygen species (ROS) are a double-edged sword in biology. On one hand, they are natural byproducts of mitochondrial respiration and play important signaling roles in cell adaptation, repair, and immune defense. In youthful, healthy cells, low levels of ROS act as beneficial messengers that fine-tune metabolism and trigger protective antioxidant responses — a process known as mitohormesis. However, as mitochondria age and become less efficient, they produce excessive ROS that overwhelm the cell’s antioxidant defenses. This oxidative overload damages DNA, lipids, and proteins, impairing cellular structures and signaling pathways. Over time, these molecular injuries accumulate, accelerating tissue degeneration and contributing to diseases such as Alzheimer’s, Parkinson’s, and cardiovascular decline.

3. Out with the Old — or Not

Cells have a sophisticated quality-control system to maintain mitochondrial health, and a central part of this system is mitophagy — the targeted degradation and recycling of damaged mitochondria. Under normal conditions, faulty mitochondria are tagged and removed to make way for new, fully functional ones. However, with age, this self-renewal process slows down. The mechanisms that detect and dispose of defective mitochondria become less responsive, leading to the accumulation of dysfunctional organelles within the cell. These impaired mitochondria not only produce less energy but also leak harmful molecules that exacerbate oxidative stress. The gradual buildup of damaged mitochondria is a critical contributor to the decline in cellular vitality and resilience seen in aging tissues.

4. Inflammation from Within

When mitochondria become damaged beyond repair, they can release fragments of their own DNA and proteins into the cytoplasm or bloodstream. Interestingly, because mitochondrial DNA evolved from ancient bacteria, the immune system often mistakes it for a foreign invader. Over time, this persistent low-level inflammation — termed inflammaging — becomes a major driver of age-related tissue damage and chronic diseases, including atherosclerosis, diabetes, and neurodegeneration. In this way, failing mitochondria act not only as victims of cellular aging but also as active participants that amplify the inflammatory processes underlying it.

Focus on Mitochondria for anti-aging interventions

Recent advances in nanoengineered mitochondria (biohybrid systems that integrate isolated mitochondria with functional nanomaterials) may soon allow us to repair and enhance them, opening new paths toward better health and longevity. Unlike conventional mitochondrial transplantation, which simply transfers healthy mitochondria to damaged tissues, these nano-biohybrids enhance organelle stability, boost ATP production, and enable targeted delivery. Preclinical studies show promising results in cardiovascular, neurodegenerative, and age-related disorders, including breakthroughs where engineered mitochondria prevented intervertebral disc degeneration in rats by restoring mitochondrial function and modulating key signaling pathways such as mtDNA/SPARC-STING. By bridging materials science and mitochondrial biology, nanoengineered mitochondria could emerge as a powerful new tool in longevity therapeutics, revitalizing energy metabolism at its source.

Several strategies are being developed to counteract mitochondrial decline. One major approach involves antioxidants targeted specifically to mitochondria, such as MitoQ and MitoVitE, which aim to neutralize excess ROS and reduce oxidative damage. Another focuses on stimulating mitochondrial biogenesis, often through pathways like PGC-1α activation; exercise remains the best-validated method for this, but pharmacological enhancers are under investigation. Therapies that enhance mitophagy — the selective clearance of damaged mitochondria — are also of growing interest, as impaired mitophagy is a hallmark of aging cells. Other approaches include modulating mitochondrial metabolism, for instance by increasing NAD⁺ levels, which support mitochondrial redox reactions and energy metabolism.

Among the most promising experimental therapies is Elamipretide (SS-31), a mitochondria-targeted peptide that binds to cardiolipin in the inner mitochondrial membrane, stabilizing its structure and improving the efficiency of the electron transport chain. In preclinical studies, Elamipretide improved muscle endurance, cardiac function, and mitochondrial energetics, and early human trials have shown enhanced ATP production in older adults. 

Collectively, these mitochondrial-targeted interventions represent one of the most active areas in aging research. While most remain at early stages of development, they illustrate a broader therapeutic shift—from treating single age-related diseases to addressing the underlying cellular dysfunctions that drive aging itself. Lifestyle interventions such as exercise and caloric moderation remain the most reliable means to preserve mitochondrial health, but ongoing trials of peptides like Elamipretide, NAD⁺ precursors, and mitophagy activators could soon expand the toolkit for promoting healthier aging. The field’s success will depend on overcoming key challenges such as long-term safety, delivery specificity, and demonstrating true improvements in human healthspan rather than just cellular biomarkers.

The good news of the month. Human cells reduce senescence markers in aged macaques.

---

In a study published in Cell (September 4, 2025), scientists demonstrated that infusing senescence-resistant human mesenchymal progenitor cells (SRCs) into aged macaques significantly reduced markers of aging and improved cognitive, bone, and reproductive function.

This is very promising. It is hoped that those monkeys will live long enough to demonstrate that the progenitor cells prolong the healthy lifespan.

This month’s theme: Compounds for Longevity

---

Introduction

Most humans would love a pill without negative effects and largely extending healthy life. Sadly, until today, there is no product making a far longer healthier life possible for humans. This newsletter is about the compounds for longevity that are the most studied at the moment.

Metformin

A widely prescribed drug for type 2 diabetes has garnered significant interest for its potential role in promoting longevity and healthy aging. Beyond its glucose-lowering effects, metformin influences multiple cellular pathways associated with aging, including activation of AMPK, inhibition of mTOR, reduction of oxidative stress, and improvement of mitochondrial function. These actions collectively mimic some of the effects of caloric restriction, a well-established intervention for lifespan extension in model organisms. Preclinical studies in mice and other animals have shown that metformin can extend healthspan, reduce the incidence of age-related diseases such as cancer and cardiovascular disease, and improve metabolic and cognitive function. Observational studies in humans, particularly among individuals with diabetes, suggest that metformin use is associated with lower all-cause mortality and a reduced risk of age-related conditions compared to non-users. However, randomized controlled trials specifically evaluating longevity in non-diabetic populations are sadly not yet startedongoing, most notably the TAME (Targeting Aging with Metformin) trial.

mTOR Inhibitors

Rapamycin and its analogs (rapalogs such as everolimus, temsirolimus, and ridaforolimus), are among the most validated pharmacological interventions for extending lifespan across model organisms and are now showing promise in humans. These drugs primarily inhibit mTORC1, slowing growth and enhancing stress resistance, but dose and context are critical: while moderate dosing improves longevity, excessive inhibition can impair fertility, immunity, or metabolism. Beyond aging, rapalogs are being investigated in oncology, reproductive health (reducing endometriosis progression and preserving ovarian function), and neuro-ophthalmology (protecting against glaucoma through autophagy). Recent advances such as RapaLinks—next-generation compounds targeting both mTORC1 and mTORC2—offer stronger, more durable inhibition and may overcome drug resistance seen in cancer. Overall, rapalogs remain central to longevity research, with evidence pointing to sex-specific, tissue-specific, and dose-dependent benefits that make them promising, though nuanced, tools for extending healthspan.

NMN

By replenishing NAD⁺, NMN has been shown in animal studies to improve insulin sensitivity, vascular function, and cognitive performance, while extending healthspan and in some cases lifespan. Recent work highlights the role of NMN transporters and extracellular NAMPT in systemic aging regulation, leading to the “NAD World 3.0” framework that emphasizes multi-tissue communication in longevity control. NMN supplementation has also been found to restore NAD⁺ levels and reduce inflammation through pathways like TLR4/NF-κB/MAPK, suggesting protective effects against age-related ovarian decline. Human clinical data remain limited but show that NMN is generally safe and well-tolerated, capable of raising blood NAD⁺ levels. Overall, NMN represents a leading candidate among NAD⁺ boosters, with strong mechanistic rationale and encouraging early results, but confirmation from large-scale clinical trials is still needed.

Senolytics

Dasatinib combined with quercetin (D+Q) is one of the most studied senolytic strategies in the context of longevity. Aging is partly driven by the accumulation of senescent cells, which stop dividing but secrete pro-inflammatory factors known as the senescence-associated secretory phenotype (SASP), contributing to tissue dysfunction, chronic inflammation, and age-related diseases. Dasatinib, a tyrosine kinase inhibitor originally used in leukemia, selectively induces apoptosis in senescent preadipocytes and endothelial cells, while quercetin, a natural flavonoid, targets senescent endothelial cells and fibroblasts. Together, they provide a broader spectrum of senescent cell clearance than either agent alone. Preclinical studies in mice have shown that intermittent administration of D+Q reduces senescent cell burden in fat, liver, and kidney, improves physical function such as grip strength and endurance, reduces age-related pathologies, including fibrosis and atherosclerosis, and enhances healthspan. Early human pilot studies, including in patients with idiopathic pulmonary fibrosis and age-related dysfunction, suggest that intermittent D+Q therapy can decrease senescence markers and systemic inflammation, potentially improving physical performance and tissue function. While these results are promising, long-term effects on human lifespan and healthspan are still unknown, and dasatinib carries potential serious side effects, so its use requires medical supervision.

GLP-1 

Glucagon-like peptide-1 is a hormone primarily known for its role in glucose metabolism and appetite regulation, but emerging evidence suggests it may also influence longevity and healthy aging. GLP-1 receptor agonists, such as liraglutide and semaglutide, improve insulin sensitivity, reduce systemic inflammation, and promote weight loss, all of which are key factors in mitigating age-related metabolic and cardiovascular diseases. Beyond metabolic effects, GLP-1 signaling has been shown in preclinical studies to protect against oxidative stress, improve endothelial function, and enhance mitochondrial health, mechanisms that are closely linked to cellular aging. Animal studies indicate that GLP-1 receptor activation can improve cardiovascular outcomes, reduce neurodegeneration, and extend healthspan. Human observational and clinical data suggest potential benefits in reducing the incidence of type 2 diabetes, cardiovascular events, and possibly cognitive decline. Although direct evidence for lifespan extension in humans is still limited, GLP-1–based therapies appear to target several hallmarks of aging, making them a promising avenue for promoting longevity and metabolic resilience.

Glucosamine

This naturally occurring amino sugar commonly used as a dietary supplement for joint health, has recently drawn attention for its potential role in longevity. Beyond its effects on cartilage and osteoarthritis, preclinical studies suggest that glucosamine may influence aging through several mechanisms, including reducing chronic inflammation, modulating nutrient-sensing pathways such as mTOR and AMPK, and promoting autophagy, all of which are linked to extended healthspan. Epidemiological studies, particularly large cohort studies in humans, have observed associations between regular glucosamine supplementation and lower overall mortality, reduced risk of cardiovascular disease, and decreased incidence of some age-related diseases. While the exact mechanisms are still being elucidated, glucosamine appears to act as a mild caloric restriction mimetic, supporting cellular homeostasis and potentially contributing to healthier aging. Its safety profile is generally favorable, making it an attractive candidate for longevity research, though randomized controlled trials specifically targeting aging outcomes are still limited.

Lesser-known therapeutic compounds

SGLT2 inhibitors (ex : dapagliflozin, canagliflozin)

SGLT2 inhibitors, such as dapagliflozin and canagliflozin, offer significant benefits for kidney, heart, and metabolic health. These medications help improve glucose control while also reducing cardiovascular and renal risks. Interestingly, canagliflozin has even been shown to extend lifespan in male mice but not female and to slow the development of age-related lesions in the heart, kidneys, liver, and adrenal glands in genetically heterogeneous male mice. 

Urolithin A

Urolithin A is a natural mitophagy activator that helps promote the removal of damaged mitochondria, thereby improving cellular energy and health. It is well tolerated in humans and has shown promising effects on mitochondrial function in clinical studies. Ongoing trials are investigating its potential in Alzheimer’s disease, where it has been shown to restore mitophagy and lysosomal function (which involves the cell’s “recycling centers” that break down and clear waste, helping maintain healthy cellular homeostasis and neuronal function).

TNIK 

TNIK(Traf2- and Nck-interacting kinase) inhibitors are an emerging class of compounds being explored for longevity because of their role in pathways linked to cellular senescence, inflammation, and fibrosis. Recent AI-driven and robotics-lab studies identified the inhibitor INS018_055 which reduced markers of senescence such as the senescence-associated secretory phenotype (SASP) while preserving healthy cell function. Early clinical data in patients with idiopathic pulmonary fibrosis, a disease strongly tied to aging, showed that TNIK inhibition was safe and improved lung function. Howeverthere is still no evidence that TNIK inhibitors extend lifespan in animal models or humans, and long-term safety data remain limited.

The good news of the month. GLP-1 Receptor Agonist Use Reduces Heart Failure Mortality.

---

Some longevists affirm that GLP-1 can be considered the first real longevity drug useful for most people. Actually, it could be useful because most people have an unbalanced diet.

GLP-1 receptor agonist has various positive effects. It was recently established that patients initiating semaglutide or tirzepatide had a more than 40% lower risk of hospitalization for heart failure or all-cause mortality compared with sitagliptin (a glucose-lowering drug with no effect on heart failure end points).
