In vitro
In vitro	In HEK-293 cells, phosphorylation of the endogenous GSK3α on Tyr279 is greatly decreased after prolonged incubation with Kenpaullone. Also, the Phosphorylation of the endogenous GSK3β also decreases, although less markedly. Kenpaullone also induces the dephosphorylation of both GSK3 isoforms in SH-SY5Y cells and PC12 cells. Kenpaullone (20µM) strongly suppresses the autophosphorylation of GSK3β at Tyr216 in vitro whether GSK3 is expressed in Sf21 cells or in E. coli^[2]^[3].
