Use

Mechanistic target of rapamycin (mTOR) is a serine/threonine-specific protein kinase in the PI3/PI4-kinase family. mTOR was named after the natural macrolide rapamycin, also known as sirolimus, which was isolated from a soil sample from Easter Island in the 1970s and later evaluated as an immunosuppressive agent. The anticancer activity of rapamycin was discovered in the 1980s, although the mechanismof action and the identification of the rapamycin target, mTOR, were not elucidated until the 1990s. Rapamycin and its macrocyclic analogues, such as temsirolimus (Torisel(R), Wyeth/Pfizer) and everolimus (Afinitor(R), Novartis), are grouped as rapalogs that constitute the first-generation mTOR inhibitors. Rapamycin was approved by the US FDA in 1999 as an immunosuppressive agent to prevent organ rejection in patients receiving kidney transplants. Although a large number of clinical studies have been performed to evaluate the anticancer activities of sirolimus in different types of cancers, such as invasive bladder cancer, breast cancer, and leukemia, most studies show limited efficacy. Outside oncological indications, sirolimus was approved by FDA for the treatment of a rare progressive lung disease lymphangioleiomyomatosis in 2015. Temsirolimus was approved for the treatment of advanced RCC. Everolimus was approved in the EU for the prevention of organ rejection in heart and kidney transplant recipients before FDA approved it in 2009 for the treatment of advanced RCC resistant to sunitinib or sorafenib and for the treatment of advanced or metastatic gastrointestinal and lung tumors in 2016. Additionally, rapamycin and rapalogs are being investigated as antiaging therapeutics or for the treatment of age-related diseases. Studies have revealed that mTOR activity can be retained under hypoxic conditions via mutations in the PI3K pathway, leading to increased translation and hypoxic gene expression and tumor progression.
