Rapamycin (sirolimus) is an mTOR (mechanistic Target of Rapamycin) inhibitor that blocks protein synthesis and cellular growth pathways. This compound mimics caloric restriction effects, potentially extending lifespan while providing immunosuppressive and anti-aging benefits.
Reported Benefits (Provisional)
Origin & History
Rapamycin, also known as Sirolimus, is a macrolide compound originally discovered in soil samples from Easter Island. It is produced by the bacterium Streptomyces hygroscopicus and is primarily used as an immunosuppressant in organ transplantation.
Research Narrative (Provisional)
Numerous RCTs and animal studies have explored rapamycin's effects on lifespan extension and cancer inhibition. Meta-analyses support its efficacy in organ transplant patients.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
- Macrolide compound with immunosuppressive properties. - Inhibits the mammalian target of rapamycin (mTOR) pathway. - Derived from Streptomyces hygroscopicus bacteria.
Reported Mechanism (Provisional)
Rapamycin binds to the intracellular protein FKBP12 to form a complex that inhibits mTOR Complex 1 (mTORC1), blocking downstream signaling pathways including S6K1 and 4E-BP1. This inhibition reduces protein synthesis, autophagy activation, and cellular senescence while mimicking the molecular effects of caloric restriction. The compound also affects mTOR Complex 2 (mTORC2) with chronic use, influencing Akt signaling and glucose metabolism.
Clinical Narrative (Provisional)
Human studies on rapamycin for longevity are limited, with most anti-aging research conducted in animal models showing 20-30% lifespan extension in mice. Clinical trials have primarily focused on its immunosuppressive effects in organ transplant patients, with doses of 1-5mg daily. Small pilot studies suggest potential benefits for age-related decline, but large-scale human longevity trials are lacking. The evidence for anti-aging effects in humans remains preliminary and requires further investigation.
