mTOR inhibitor

Temsirolimus is a derivative and prodrug of rapamycin (also known as sirolimus). Temsirolimus specifically inhibits the serine/threonine protein kinase mTOR (mammalian target of rapamycin), an enzyme implicated in multiple intracellular signaling pathways that regulate cell proliferation and survival [1, 2]. To inhibit mTOR signaling, Temsirolimus interacts with the cytosolic FK506-binding protein 12 (FKBP12) to form a complex which binds the mTOR Complex 1. Through its effects on mTOR, Temsirolimus can inhibit cell proliferation and induce apoptosis, in addition to the inhibiton of angiogenesis in cancer models [3, 4].
