Several members of a new family of non-sugar-type α-glucosidase inhibitors, bearing a phthalimide moiety connected to a variously substituted phenoxy ring by an alkyl chain, were synthesized and their activities were investigated. The efficacy of the inhibition activity appeared to be governed by the chain length of the substrate. Substrates possessing 10 carbons afforded the highest levels of activity

A series of 9-N-substituted berberine derivatives were synthesized and biologically evaluated as antioxidant and inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase and amyloid-beta aggregation. Most of these compounds exhibited very good antioxidant activities, inhibitive activities of AChE and amyloid-beta aggregation. Among them, compound 8d, (o-methylphenethyl)amino linked at the 9-position of berberine, was found to be a good antioxidant (with 4.05 mu M of Trolox equivalents), potent inhibitor of AChE (an IC50 value of 0.027 mu M), and high active inhibitor of amyloid-beta aggregation (an IC50 value of 2.73 mu M).
