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).

|Cell Lines||seipin-nKO mice|
|Incubation Time||28 days|
|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|

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
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.
