TDZD-8 is an inhibitor of glycogen synthase kinase-3β (GSK-3β) with IC50 value of 1.4μM [1].

TDZD-8 is a potent inhibitor of GSK-3β. It is found to act as a noncompetitive inhibitor of ATP binding. TDZD-8 is selective against GSK-3β over other protein kinases including PKA, casein kinase II and cyclin dependent kinase 1 (Cdk-1/cyclin B). However, it is also reported that TDZD-8 can inhibit the protein kinase C isoforms PKCβI and PKCδ with IC50 values of 1.4μM and 1.1μM, respectively [1, 2].

In cellular assay, TDZD-8 is found to decrease PDT-induced necrosis of neurons and decrease PDT-induced apoptosis of glial cells through inhibiting GSK-3β as well as PKC. Besides that, TDZD-8 also has anti-leukemia activity in many primary human leukemia cells. It is probably due to its inhibition of PKC and FLT3 [3].
