<p style=/line-height:25px/>TDZD-8(NP 01139) is a selective inhibitor of GSK-3, a thiadiazolidinone derivative, non-ATP competitive inhibitor of GSK-3β (IC50 = 2 μM); does not inhibit Cdk-1/cyclin B, CK-II, PKA or PKC at >100 μM.<br>IC50 Value: 2 uM (GSK3β)<br>Target: GSK-3β<br>in vitro: Prophylactic or therapeutic administration of TDZD-8 caused the phosphorylation (Ser(9)) and hence inactivation of GSK-3beta. Infarct volume and levels of S100B protein, a marker of cerebral injury, were reduced by TDZD-8. This was associated with a significant reduction in markers of oxidative stress, apoptosis, and the inflammatory response resulting from cerebral I/R [1]. Notably, cell death was frequently evident within 2 hours or less of TDZD-8 exposure. Cellular and molecular studies indicate that the mechanism by which TDZD-8 induces cell death involves rapid loss of membrane integrity, depletion of free thiols, and inhibition of both the PKC and FLT3 signaling pathways [4].<br>in vivo: Using mouse xenograft models, we demonstrated that LiCl and TDZD-8 significantly suppressed tumor development and growth of subcutaneous xenografts derived from human prostate cancer cells. Similarly, in the TRAMP mice, TDZD-8 and L803-mts reduced the incidence and tumor burden in the prostate lobes [2]. TDZD-8 significantly reduced the degree of pancreas injury, amylase, and lipase serum levels (p < .01); nuclear factor-kappaB activation (p < .01); the production of tumor necrosis factor-alpha and interleukin-1beta (p < .01); the expression of adhesion molecules and neutrophil accumulation (p < .01); the formation of oxygen and nitrogen-derived radicals (p < .01); the degree of lipid peroxidation (p < .01); the expression of transforming growth factor-beta and vascular endothelial growth factor (p < .01); and-ultimately-the mortality rate (p < .01) in rats [3].<br><br></p>
