Key Features (Medical Focus)

  • Immunosuppressant Power: Slows the immune system to prevent organ rejection (e.g., kidney, liver transplants)—saves lives post-transplant
  • Anti-Cancer Effects: Inhibits cell growth—used to treat rare cancers (e.g., renal cell carcinoma, mantle cell lymphoma)
  • Targeted Action: Works on the mTOR pathway (a key cell growth regulator)—fewer off-target side effects than older immunosuppressants
  • Pharmaceutical Grade Only: No over-the-counter versions—requires a doctor’s prescription to ensure safe dosing
  • Potencial de investigación: Studied for age-related diseases (e.g., Alzheimer’s) in labs, but these uses are not yet approved for medical practice

Industry Applications (Medical & Research Only)

  1. Organ Transplant Medicine
    • Kidney/Liver Transplants: Prescribed daily (0.5–2mg) to prevent immune rejection—often combined with other immunosuppressants (e.g., tacrolimus) for better results
    • Heart/Lung Transplants: Used in select cases to support long-term graft survival (dosing adjusted for patient weight/health)
  1. Oncology (Cancer Treatment)
    • Rare Cancers: Prescribed for advanced renal cell carcinoma (kidney cancer) or mantle cell lymphoma—slows tumor growth by blocking mTOR
    • Kaposi’s Sarcoma: Used to treat this AIDS-related cancer in patients who can’t tolerate other treatments
  1. Rare Disease Treatment
    • Tuberous Sclerosis Complex (TSC): Approved for treating seizures and kidney tumors in adults/children with TSC—targets abnormal cell growth caused by TSC mutations
    • Lymphangioleiomyomatosis (LAM): A rare lung disease—reduces lung lesions and improves breathing in affected patients
  1. Biotech Research
    • Age-Related Disease Studies: Used in labs to study mTOR’s role in aging, Alzheimer’s, and Parkinson’s—no approved medical use for these yet
    • Cell Biology: A tool for researching cell growth and survival pathways (common in academic and pharmaceutical labs)
  1. Veterinary Medicine (Specialized)
    • Pet Organ Transplants: Rarely used in dogs/cats post-kidney transplants (veterinarian-prescribed, adjusted for animal size)

Critical Safety Note

Rapamycin has serious side effects (e.g., increased infection risk, high cholesterol, kidney issues) and interacts with many drugs. It is not a supplement—do not use without a doctor’s prescription and close medical monitoring.

Rapamycin: Pharmaceutical-Grade mTOR Inhibitor for Research & Medical Applications – Manufacturer & Exporter Guide

1. What is Rapamycin?
For research institutions and pharmaceutical companies exploring longevity and immune modulation, Rapamycin (Sirolimus) represents one of the most significant discoveries in molecular biology. This macrocyclic lactone compound, originally isolated from Streptomyces hygroscopicus found in Easter Island soil, has revolutionized our understanding of cellular metabolism and aging processes. As a potent mTOR (mechanistic target of rapamycin) inhibitor, it serves as a critical tool for research into aging, cancer, and autoimmune disorders. While primarily used as an immunosuppressant drug in transplant medicine, its research applications continue to expand into novel therapeutic areas.
