LY2090314

LY2090314 is potent and selective inhibitor of glycogen synthase kinase 3 (GSK3) with IC50 values of 1.5 and 0.9 nM for human recombinant GSK3alpha and GSK3beta, respectively. It has >10-fold selectivity for GSK3 over a panel of 40 kinases at a concentration of 20 µM. LY2090314 induces time-dependent stabilization of beta-catenin total protein and activates Wnt signaling in vitro. It has potent antiproliferative activity in BRAF wild-type/NRAS mutant and BRAF mutant melanoma cell lines (IC50s = 6.0-11.8 nM) but has limited to no activity in non-melanoma cell lines with (IC50s = 430 to >20,000 nM). Knockdown of beta-catenin in A375 and M14 melanoma cells induces LY2090314 resistance in vitro, indicating that LY2090314-induced cell death is dependent upon Wnt activation. In vivo, LY2090314 reduces tumor volume in a murine A375 melanoma xenograft model as a single agent and synergizes with decabarzine for a greater antitumor effect. Formulations containing LY2090314 are under clinical investigation for the treatment of advanced solid tumors.Formal Name: 3-[9-fluoro-1,2,3,4-tetrahydro-2-(1-piperidinylcarbonyl)pyrrolo[3,2,1-jk][1,4]benzodiazepin-7-yl]-4-imidazo[1,2-a]pyridin-3-yl-1H-pyrrole-2,5-dione.
