TCS 2002 is a Wnt/β-catenin signaling modulator, which is associated with diseases such as cancer and Alzheimer’s diasease.
tcs 2002 is a potent inhibitor of gsk-3β with ic50 value of 35 nm [1].glycogen synthase kinase 3 (gsk-3) is a serine/threonine protein kinase and functions by phosphorylating a serine or threonine residue on its target protein. gsk3β plays an important role in neuronal cell development, energy metabolism and body pattern formation.tcs 2002 is a potent gsk -3β inhibitor with ic50 value of 35 nm. (s) -tcs 2002 and (r) -tcs 2002 inhibited gsk-3β with ic50 values of 34 and 140 nm, respectively. tcs 2002 exhibited good bioavailability (f=40%) and solubility (38 μg/ml). (s) -tcs 2002 showed no inhibitory activity against 12 tyrosine kinases and 10 serine/threonine kinases up to 10 μm, indicating that (s) -tcs 2002 was a highly selective gsk -3β inhibitor [1].in mice, cold water stress (cws) induced tau hyperphosphorylation at several gsk -3β directed sites such as s199, thr205, thr231 and ser396. (s) -tcs 2002 significantly inhibited tau phosphorylation by 35% [1].
TCS2002 (Compound 9b) (1-3 mg/kg;1-24 hours; GS rats andC57BL/6N mice) exhibits good pharmacokinetic profiles and favor able BBB permeability with AUC0-24h value is 734 ng h/g and Kp value (ratio of brain and plasma) is 1.6[1].
