PP242 blocks the phosphorylation of Akt at S473 and prevents its activation. PP242 inhibits the proliferation of primary cells more efficiently than rapamycin. Unlike rapamycin, it also inhibits cap-dependent translation under conditions. Feldman, M.E., et al. "Active-site inhibitors of mTOR target rapamycin-resistant outputs of mTORC1 and mTORC2." PLoS Biol. 7: 371-383 (2009).PP242, but not rapamycin, induced death of mouse and human leukemia cells in vitro. In vivo, PP242 delayed leukemia onset and enhanced the effects of the front-line tyrosine kinase inhibitors more effectively than does rapamycin. However, PP242 had much weaker effects than rapamycin on the proliferation of normal lymphocytes. Janes, M.R., et al. "Effective and selective targeting of leukemia cells using a TORC1/2 kinase inhibitor." Nat. Med. 16: 205-213 (2010).PP242 inhibited basal serum- and glucocorticoid-inducible protein kinase 1 (SGK1) activity and prevented insulin- and dexamethasone-induced SGK1 activation, possibly by suppressing TORC1/2. It inhibited basal Na+ absorption modestly and insulin/dexamethasone-induced Na+ transport substantially. Mansley, M.K. and Wilson, S.M. "Dysregulation of epithelial Na+ absorption induced by inhibition of the kinases TORC1 and TORC2." Br. J. Pharmacol. 161: 1778-1792 (2010).PP242 inhibited growth and induced apoptosis of multiple myeloma (MM) cells more effectively than rapamycin. PP242 was an effective inhibitor of primary MM cells in vitro and growth of 8226 cells in mice. Combining bortezomib with PP242 resulted in synergistic anti-MM effects. Hoang, B., et al. "Targeting TORC2 in multiple myeloma with a new mTOR kinase inhibitor." Blood 116: 4560-4568 (2010).PP242 significantly augmented histone deacetylase inhibitor-induced apoptosis in hepatocellular carcinoma cells. Shao, H., et al.
