MedKoo CAT#: 406278

CAS#: 133052-90-1

Description: GF-109203X is a potent and highly selective PCK inhibitor, which inhibits PKC isozymes alpha, beta 1, beta 2, gamma, delta and epsilon in vitro . GF-109203X inhibited GSK-3 in vitro, when assayed either in cell lysates (IC(50) 360 nM or in GSK-3beta immunoprecipitates (IC(50) 170 nM derived from rat epididymal adipocytes. Pretreatment of adipocytes with GF-109203X (5 microM) reduced GSK-3 activity in total cell lysates, to 25.1+/-4.3% of control.
