PF-04802367是GSK-3高选择性抑制剂，对GSK-3β酶的IC50为 2.1 nM。它抑制两种 GSK-3 亚型（GSK-3α和GSK-3β）效果差不多，IC50值分别为 10.0 和 9.0 nM。它具有理想的中枢神经系统特性和效力。

PF-04802367 is a highly selective GSK-3 inhibitor with an IC50 of 2.1 nM based on a recombinant human GSK-3β enzyme assay and 1.1 nM based on ADP-Glo assay. It shows desirable central nervous system (CNS) properties and potency. It is equally effective at inhibition of the two known GSK-3 isoforms (GSK-3α and GSK-3β) with IC50 values of 10.0 and 9.0 nM in mobility shift assays, respectively.

PF-04802367 (PF-367) is efficient at inhibiting GSK-3β enzymatic activity in vitro with ligand and lipophilic efficiency scores of 0.46 and 7.0, respectively[1]. PF-367 has reasonable in vitro stability in human hepatic microsomes (t1/2=78.7 min), has excellent passive permeability[1]. In a stable inducible CHO cell line over-expressing GSK-3β and its substrate tau, PF-367 inhibited phosphorylation of tau with an IC50 of 466 nM[1]. PF-367 has good cell viability (IC50 of 117 μM in THLE cytotoxicity assays) and an IC50 >100 μM in a hERG screening assay[1]. PF-367 shows significant right shifts against β-catenin translocation in HeLa cells with EC50 of 6.2 μM, gene transcription in U20S cells with EC50 of 20.6 μM, and cell proliferation in HeLa cells as evaluated by Ki-67 incorporation with EC50 of 9.0 μM[1].

PF-04802367 (PF-367) a potent GSK-3 inhibitor with exceptional kinome selectivity that modulates phosphorylated tau levels in vivo. Inhibition of phosphorylation of tau in brain by PF-367 (A single subcutaneous of 1, 3.2, 10, 32 or 50 mg/kg) is dose-dependent[1]. PF-04802367 (PF-367), a potent type-I dual GSK-3α/β inhibitor, showing promising absorption; distribution, metabolism and elimination (ADME) properties combined with robust CNS/peripheral p-Tau and muscle phosphorylated glycogen synthase (pGS) inhibition in vivo[2].
