P11149, a derivative of Galanthamine, acts as a competitive, orally active, and selective AChE inhibitor with the ability to weakly penetrate the blood-brain barrier (BBB). It demonstrates selective inhibition, exhibiting an IC50 of 1.3 μM for rat BChE/AChE, and shows central cholinergic activity, behavioral efficacy, and safety. P11149 is utilized in Alzheimer’s disease research[1].

BChE/AChE (rat):1.3 μM (IC50)

P11149 is a GAL analog that is rapidly hydrolyzed in vivo to yield the potent AChE inhibitor, 6-DMG[1].P11149 exhibits greater s.c. bioavailability than p.o. [1].Oral P11149 in mice produces Sal, Lac and tremors at doses similar to those in rats, whereas 6-DMG, P1 1012 and GAL produces Sal and Lac at doses lower than those in rats[1].P11149 exhibits T1/2(el) of 2.4 h and Cmax of 585 ng/mL in rat plasma[1].
