چکیده

Some new nitrogen bridge-head pyrido[1,2-b][1,2,4]triazepines incorporating 6methylchromone moiety have been synthesized from the reaction of 1,6-diamino-4-(6methyl-4-oxo-4H-chromen-3-yl)-2-oxo-1,2-dihydropyridine-3,5-dicarbonitrile (4) with some α,γ-bifunctional electrophiles including 2-cyano-3,3-bis(methylthio)acrylonitrile, 2cyano-3,3-bis(methylthio)prop-2-enamide, 5-chloro-3-methyl-1-phenylpyrazole-4carboxaldehyde, 2-chloro-3-formylquinoline, p-methoxybenzylidene-malononitrile, ethyl 2cyano-3-(4-methoxyphenyl)prop-2-enoate, chromone-3-carbonitrile. Structures of the newly synthesized products have been deduced upon the help of elemental analysis and spectral data. The synthesized compounds were screened for their antimicrobial activity.

New series of spiroindeno[1,2-b]pyrido[2,3-d]pyrimidine-5,3′-indolines as new urease inhibitors were synthesized by the catalytic procedure in high yield and short reaction time. In this method, biacidic carbon was prepared as a novel heterogeneous acid and was subsequently used as an efficient catalyst in this synthesis. The inhibitory activities of synthesized compounds were tested against Ja...

Considerable interest has been focused on the triazole structure, which has been known to possess a broad spectrum of biological activities such as antitumor, anti-inflammatory, antimicrobial, antiviral, and anticonvulsant activities. Before this, several heterocyclic compounds containing triazole were synthesized that had shown considerable anticonvulsant activity. As part of our continuous re...
