How to use

In Vitro:

The pyridine carboxamide of GSK-3β inhibitor 2 (Compound 3) makes hydrogen bonds with the hinge V135 backbone amide, and the carbonyl oxygen of the thiazolyl primary amide formed a critical hydrogen bond with K85. The quality of the electron density for the methyl group of the methoxy moiety in GSK-3β inhibitor 2 does not allow its unambiguous placement in the model, but a small molecule crystal structure of GSK-3β inhibitor 2 determined by single crystal X-ray diffraction method confirmed the intramolecular hydrogen bonding between the methoxy -O- and the amide N-H in GSK-3β inhibitor 2.

In Vivo:

The elevation of hyperphosphorylated Tau (pTau) is mimicked in LaFerla 3xTg-C57BL6 mice, and accordingly, these mice are used as an in vivo model of Alzheimer’s disease. GSK-3β inhibitor 2 (Compound 3) shows a significant reduction in pTau396 when administered orally at 30 mg/kg as a nanosuspension to LaFerla 3xTg-C57BL6 male mice. GSK-3β inhibitor 2 shows only modest brain exposure (B/P = 0.26) as determined as a single time point.
