Tetrahydropyranodiquinolin-8-amines as new, non hepatotoxic, antioxidant, and acetylcholinesterase inhibitors for Alzheimer's disease therapy
摘要:
Herein we report an efficient two step synthesis and biological assessment of 12 racemic tetrahydropyranodiquinolin-8-amines derivatives as antioxidant, cholinesterase inhibitors and non-hepatotoxic agents. Based on the results of the primary screening, we identified 7-(3-methoxypheny1)-9,10,11,12-tetrahydro-7H-pyrano[2,3-b:5,6-h']diquinolin-8-amine (2h) as a particularly interesting nonhepatotoxic compound that shows moderate antioxidant activity (1.83 equiv Trolox in the ORAC assay), a non competitive inhibition of hAChE (IC50 = 0.75 +/- 0.01 mu M), and brain permeable as determined by the PAMPA-Blood Brain Barrier assay.

A series of halogenated 2-amino-4-aryl-4H-pyrano[3,2-h]quinoline-3-carbonitrile derivatives were prepared via interaction of 8-hydroxyquinoline, 5-chloro-8-hydroxyquinoline, and 8-hydroxy-2-methylquinoline with various α-cyanocinnamonitriles. The assignments of the structure of all synthesized compounds were based on spectral data. The cytotoxic activities of the synthesized compounds against four
