单词 | topical sirolimus |
释义 | topical sirolimus A topical formulation containing the macrolide sirolimus (rapamycin), which is produced by the organism Streptomyces hygroscopicus, with potential anti-proliferative activity. Upon application of topical sirolimus, this agent migrates into the skin and is internalized by the affected cells. In turn, sirolimus binds to the immunophilin FK binding protein-12 (FKBP-12) and forms a sirolimus:FKBP-12 complex. This complex binds to and inhibits the activity of the serine/threonine kinase mammalian target of rapamycin (mTOR). It also decreases the production of vascular endothelial growth factor (VEGF) and results in the suppression of cellular proliferation. |
