9-O-Acetamide analogs of berberine bromide were prepared in 20–87% yields via reaction of the isoquinoline alkaloid berberrubine with tertiary amides of bromoacetic acid. Aminolysis did not occur during reaction of methyl-2-(9-demethoxyberberine bromide-9-yl)hydroxyacetate with secondary amines. The corresponding acid or its ethyl ester was isolated.
A series of novel 9-O-substituted-berberine derivatives were synthesized and their anti-inflammatory activities were evaluated. Among them, compounds 3i and 5e exhibited excellent anti-inflammatory potential.

of novel berberine derivatives were designed, synthesized, and biologically evaluated as inhibitors of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among these derivatives, compound 48a, berberine linked with 3-methylpyridinium by a 2-carbon spacer, was found to be a potent inhibitor of AChE, with an IC50 value of 0.048 μM and compound 40c, berberine linked with 2-thionaphthol
