LY2090314 is a potent inhibitor of glycogen synthase kinase-3 (GSK-3) with IC₅₀ values of 1.5 nM and 0.9 nM for GSK-3α and GSK-3β, respectively.

LY2090314 (20 nM) promotes a time-dependent stabilization of β-catenin total protein as well as an induction of Axin2. LY2090314 is highly selective towards GSK3 as demonstrated by its fold selectivity relative to a large panel of kinases. LY2090314 potently induces apoptotic cell death in a panel of melanoma cell lines irrespective of BRAF mutation status. Cell death induced by LY2090314 is dependent on β-catenin and GSK3β knockdown increases the sensitivity of cells to LY2090314. LY2090314 remains active in cell lines resistant to PLX4032 and has an independent mechanism of action^[2].

LY2090314 exhibits high clearance (approximating hepatic blood flow) and a moderate volume of distribution (appr 1-2 L/kg) resulting in rapid elimination (half-life appr 0.4, 0.7, and 1.8-3.4 hours in rats, dogs, and humans, respectively). LY2090314 is rapidly cleared by extensive metabolism with negligible circulating metabolite exposures due to biliary excretion of metabolites into feces with no apparent intestinal reabsorption^[1]. LY2090314 (25 mg/kg Q3D, i.v.) elevates Axin2 gene expression in vivo, demonstrates single agent activity in the A375 xenograft model of melanoma and enhances the efficacy of DTIC^[2].

Five million A375 human melanoma cancer cells are injected S.C. in the flank of female 6 to 8 week old athymic nude mice in a 1:1 mixture with matrigel. Mice are monitored daily for palpable tumors. When tumors reach appr 100 mm² mice are randomized into groups receiving either LY2090314 (25 mg/kg Q3D) or vehicle (20% Captisol/0.01N HCl) via i.v. administration. Tumor volume (measured by calipers) and animal body weight are recorded twice weekly. Tumor volumes are calculated using the formula: (a² × b)/2 (a being the smaller and b being the larger dimension of the tumor). For combination studies with DTIC (60 mg/kg QD), LY2090314 is dosed at 2.5 mg/kg Q3D and tumor growth monitored.
