Biological Activity

AR-A014418 is an ATP-competitive, and selective GSK3β inhibitor with IC50 and Ki of 104 nM and 38 nM, without significant inhibition on 26 other kinases tested. AR-A014418 inhibits tau phosphorylation at a GSK3-specific site (Ser-396) in 3T3 fibroblasts expressing human four-repeat tau protein with IC50 of 2.7 μM, and protects cultured N2A cells from death induced by blocking PI3K/PKB pathway. In hippocampal slices, AR-A014418 inhibits neurodegeneration mediated by beta-amyloid peptide. While in NGP and SH-5Y-SY cells, AR-A014418 reduces neuroendocrine markers and suppresses neuroblastoma cell growth. AR-A 014418, 48 hrs posttreatment, caused dose (25-100  μ M) dependent inhibition in U373 and U87 cell viability with also inhibition in activating tyrosine phosphorylation of GSK3alpha (Tyr 279) and beta (Tyr 216).

Results As shown in Fig. 5b, the level of cleaved caspase-3 (c-caspase-3) in the SN of 8-M-old seipin-nKO mice was higher than that in control mice (P < 0.01, n =6), whereas there was no significant difference between 3-M-old control mice and seipin-nKO mice

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
