2-Styrylquinazolones are reported as a novel class of potent anti-mycobacterial agents. Forty-six target compounds have been synthesized using one pot reaction involving isatoic anhydride, amine, and triethyl orthoacetate followed by aldehyde to construct the 2-styrylquinazolone scaffold. The anti-mycobacterial potency of the compounds was determined against H37Rv strain. Twenty-six compounds exhibited
据报道2-苯乙烯基喹唑啉酮是一类新型的有效的抗分枝杆菌药。使用一锅反应合成了46种目标化合物,该反应包括等角酸酐,胺和原乙酸三乙酯,然后通过醛来构建2-苯乙烯基喹唑酮骨架。测定了化合物对H 37 Rv株的抗分枝杆菌效力。26种化合物的抗Mtb活性在0.40–6.25μg/ mL的范围内。三种化合物8c,8d和8ab的MIC均为0.78μg/ mL,并且对治疗指数> 64的HEK 293T细胞系无毒(在50μg/ mL处抑制<50%)。最有效的化合物8ar显示MIC为0.40μg/ mL,治疗指数> 125。已经建立了这类化合物的早期结构活性关系。计算研究表明这些化合物与青霉素结合蛋白(PBPs)结合的可能性。
