Starting from small molecule mTOR inhibitor Torin1, replacement of the piperazine ring with a phenyl ring resulted in a new series of mTOR inhibitors (as exemplified by 10) that showed superior potency and selectivity for mTOR, along with significantly improved mouse liver microsome stability and a longer in vivo half-life.
