P11149 is a competitive, BBB-penetarated weakly, orally active and selective inhibitor of AChE. P11149 exhibits an IC50 of 1.3 μM for rat BChE/AChE. P11149, a Galanthamine derivative, demonstrates central cholinergic activity, behavioral efficacy and safety. P11149 is used in the study for Alzheimer’s disease[1]. 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].
