Inhibition of cholinesterase activity and amyloid aggregation by berberine-phenyl-benzoheterocyclic and tacrine-phenyl-benzoheterocyclic hybrids
摘要:
A series of berberine-phenyl-benzoheterocyclic (26-29) and tacrine-phenyl-benzoheterocyclic hybrids (44-46) were synthesised and evaluated as multifunctional anti-Alzheimer's disease agents. Compound 44b, tacrine linked with phenyl-benzothiazole by 3-carbon spacers, was the most potent AChE inhibitor with an IC50 value of 0.017 mu M. This compound demonstrated similar A beta aggregation inhibitory activity with cucurmin (51.8% vs 52.1% at 20 mu M, respectively), indicating that this hybrid is an excellent multifunctional drug candidate for AD.

(EN) This invention relates to a class of novel aliphatic amino bis-aryl compounds containing at least four carbon atoms and an amino group either substituted thereon or incorporated therein and is furhter linked or bridged to two mono- and/or bicyclic rings. Compounds of this invention reduce levels of serum cholesterol in the body without significantly reducing mevalonic metabolite synthesis. This invention relates also to pharmacological compositions and method of treatment for lowering serum cholesterol levels using the compounds of this invention.(FR) Cette invention concerne une classe de nouveaux composés amino bis-aryle aliphatiques contenant au moins quatre atomes de carbone et un groupe amino substituant ou incorporé dans la structure et en outre lié ou formant un pont avec deux groupes mono- et ou bicycliques. Les composés de cette invention réduisent les niveaux du cholestérol du sérum dans le corps sans diminuer d'une manière significative la synthèse du métabolite mévalonique. Cette invention concerne également des compostions pharmacologiques et un procédé de traitement pour diminuer les niveaux de cholestérol du sérum en utilisant les composés de cette invention.
