What Is Rapamycin and How Does It Extend Lifespan?

TL;DR

Rapamycin is a drug originally discovered as an anti-fungal agent on Easter Island, known for its ability to inhibit cell proliferation, particularly in lymphocytes. Since its FDA approval for organ transplantation in 1999, studies have shown that it can significantly extend lifespan in animals, with effects documented in rigorous scientific research.

Questions & Answers

Q: What is the origin of rapamycin and how was it discovered?

Rapamycin is a drug derived from bacteria found on Easter Island in the 1960s. It was initially identified as a potent anti-fungal agent by a chemist named Siren Seagal.

Q: How did rapamycin transition from an anti-fungal drug to being approved for organ transplantation?

After its discovery, rapamycin's anti-proliferative properties made it suitable for preventing organ rejection in transplant patients, leading to its FDA approval in 1999.

Q: What significant findings were observed in animal studies regarding rapamycin's impact on lifespan?

Studies, notably the interventions testing program, demonstrated a substantial increase in the lifespan of mice treated with rapamycin, indicating its potential for longevity enhancement.

Q: How does rapamycin compare to other drugs like metformin in terms of lifespan extension?

Unlike metformin, rapamycin has shown consistent results in extending lifespan in animal studies, making it a promising candidate for age-related interventions.
