INCB053914 phosphate

INCB053914 phosphate is an orally active, ATP-competitive inhibitor of pan-PIM kinase (PIM1, PIM2, PIM3 with IC50s of 0.24 nM, 30 nM, 0.12 nM , respectively) . (In Vitro) :Uzansertib phosphate inhibits proliferation in all multiple myeloma (MM) cell lines tested, with mean GI50 values ranging from 13.2 nM to 230.0 nM in AML, MM, DLBCL, MCL, and T-ALL cell lines.Uzansertib phosphate (0.1, 0.3, 1, 3, 10, 30, 100, 300, 1000 nM) inhibits the phosphorylation of downstream PIM kinase substrates (p70S6K/S6 and 4E-BP1) in a dose-dependent manner in MOLM-16 (AML), Pfeiffer (DLBCL), and KMS-12-PE/BM (MM) cell lines.PIM kinase-mediated phosphorylation of BAD in MOLM-16 and KMS-12-BM cells is particularly sensitive to inhibition by Uzansertib phosphate (mean IC50, 4 nM and 27 nM, respectively) . (In Vivo) :Uzansertib phosphate (25-100 mg/kg; PO; twice a day; for 15 days) inhibits tumor growth in a dose-dependent manner in mice bearing MOLM-16 (AML) or KMS-12-BM (MM) .Uzansertib phosphate demonstrates a dose-dependent inhibition of BAD phosphorylation relative to vehicle at 4 hours post dose (MOLM-16 tumors, IC50=70 nM; KMS-12-BM tumors, IC50=145 nM) .
