- Discovery of 4-morpholino-6-aryl-1H-pyrazolo[3,4-d]pyrimidines as highly potent and selective ATP-competitive inhibitors of the mammalian target of rapamycin (mTOR): Optimization of the 6-aryl substituent
-
Design and synthesis of a series of 4-morpholino-6-aryl-1H-pyrazolo[3,4-d] pyrimidines as potent and selective inhibitors of the mammalian target of rapamycin (mTOR) are described. Optimization of the 6-aryl substituent led to the discovery of inhibitors carrying 6-ureidophenyl groups, the first reported active site inhibitors of mTOR with subnanomolar inhibitory concentrations. The data presented in this paper show that 6-arylureidophenyl substituents led to potent mixed inhibitors of mTOR and phosphatidylinositol 3-kinase α (PI3K-α), whereas 6-alkylureidophenyl appendages gave highly selective mTOR inhibitors. Combination of 6-alkylureidophenyl groups with 1-carbamoylpiperidine substitution resulted in compounds with subnanomolar IC50 against mTOR and greater than 1000-fold selectivity over PI3K-α. In addition, structure based drug design resulted in the preparation of several 6-arylureidophenyl-1H-pyrazolo[3,4-d]pyrimidines, substituted in the 4-position of the arylureido moiety with water solubilizing groups. These compounds combined potent mTOR inhibition (IC50501 nM). 2009 American Chemical Society.
