Rapamycin
Rapamycin, also known as Sirolimus, is a macrolide compound with a complex structure and a wide range of biological activities. Its primary function as an immunosuppressant stems from its ability to inhibit T and B cell proliferation by interfering with the mTOR pathway. This action makes it invaluable in preventing organ transplant rejection, particularly for kidney transplants. Beyond its immunosuppressive capabilities, Rapamycin exhibits potent antitumor and antiproliferative effects, leading to its use in coating coronary stents to prevent restenosis and its investigation for various cancer treatments. Emerging research highlights its potential as an anti-aging agent and its role in managing diseases like lymphangioleiomyomatosis and even COVID-19.
- Rapamycin Immunosuppressant Properties: The drug effectively suppresses the immune system by inhibiting key signaling pathways, making it crucial for transplant patients.
- Sirolimus Anti-aging Potential: Ongoing studies explore Rapamycin's capacity to slow cellular aging and extend lifespan in various organisms.
- Rapamycin Mechanism of Action: Its core mechanism involves binding to FKBP12 and inhibiting the mTOR pathway, impacting cell cycle progression and protein synthesis.
