A novel rapamycin analog is highly selective for mTORC1 in vivo

Abstract

Rapamycin extends lifespan in model organisms by targeting mTORC1, but exerts off-target side effects via inhibition of mTORC2. Here, the authors report the identification of a selective mTORC1 inhibitor, and show that it inhibits mTORC1 activity both in vitro and in vivo, with reduced side effects on glucose homeostasis, lipid metabolism, and the immune system.
