AJ-4
AJ-4 is an orally active, blood-brain barrier-permeable GSK-3β/AChE inhibitor, with an IC50 of 4.7 nM against GSK-3β and 2.97 μM against AChE. AJ-4 increases the level of phosphorylated GSK-3β and reduces the expression of Amyloid-β and phosphorylated Tau. AJ-4 improves scopolamine-induced learning and memory impairment and alleviates hippocampal neuron damage in AD mice. AJ-4 can be used for the research of Alzheimer's disease.

AJ-4 (10 μM; 24 h) significantly restores the viability of SH-SY5Y cells damaged by Aβ25-35[1].
AJ-4 (5-20 μM; 24 h) regulates key Alzheimer's disease (AD)-related proteins in Aβ25-35-damaged SH-SY5Y cells in a concentration-dependent manner, with the specific mechanism involving upregulation of p-GSK-3β and downregulation of APP and p-Tau[1].
AJ-4 (5-20 μM; 24 h) concentration-dependently inhibits Aβ25-35-induced secretion of TNF-α and IL-1β in SH-SY5Y cells, exhibiting anti-inflammatory activity[1].
