Abstract

2-Aryl-4-morpholinothieno[3,2-d]pyrimidines are known PI3K inhibitors. This class of compounds also potently inhibited the homologous Enzyme mTOR. Replacement of the morpholine group in these compounds with an 8-oxa-3-azabicyclo[3.2.1]octane group led to mTOR inhibitors with selectivity over PI3K. Optimization of the 2-aryl substituent led to the discovery of 2-(4-ureidophenyl)-thienopyrimidines as highly potent (IC(50) <1nM) mTOR inhibitors with excellent selectivity (up to >1000-fold) over PI3K and good potency in a cellular proliferation assay (IC(50) <50nM).
