PKI-179 is an orally efficacious dual PI3K/mTOR inhibitor. PKI-197 potently inhibited in in vitro enzymatic assay PI3Ka, PI3Kg and mTORC1/mTORC2 (IC50 = 8 mM, 74 nM and 0.42 nM respectively) and it showed significant activity against MDA-361 and PC3mm2 cell lines (IC50 = 22 mM, 29 nM respectively). PKI-179 showed excellent selectivity against 361-membered kinase panel (IC50 > 50 mM). Pharmacokinetic studies of PKI-197 showed good oral bioavailability (98% in nude mouse, 46% in rat, 38% in monkey and 61% in dog) and high half-life (>60 min). Evaluation of in vivo efficacy in nude mouse model bearing MDA-361 human breast cancer tumors showed pronounced tumor growth arrest when dosed above 10 mg/Kg.
