What is Rapamycin?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is RPM which has developed particularly rapidly in recent years. Do you know about RPM?

The official answer: Rapamycin (RAPA) is a new type of macrolide immunosuppressant, a white solid crystal with a melting point of 183-185°C. It is lipophilic and soluble in organic solvents such as methanol, ethanol, acetone and chloroform, very slightly soluble in water and almost insoluble in ether. It is now often used as a drug to maintain the immunity of transplanted organs (especially kidney transplants) to slow down immune rejection after transplantation, however scientists have recently discovered another use for it: it can be used to treat Alzheimer’s disease (dementia). 

What’s the application of Rapamycin?

Member of the macrolide family of immunosuppressants. FRAP inhibitor. Binds and inhibits the target molecule of rapamycin (mTOR). A potent immunosuppressive agent with anticancer activity.
