quinazoline-based thiourea/4-thiazolidinone/chalcone hybrids. The newly synthesized compounds were studied for efficacy against several bacteria (Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, and Klebsiella pneumoniae) and fungi (Candida albicans and Aspergillus clavatus) using the broth dilution technique. From the biological evaluation, (E)-3-(3,4-dimethoxyphenyl)-1-(4-((4-(4-ethylp
在寻找新的生物实体以对抗最近的耐药微生物菌株的框架中,我们报告了一个基于喹唑啉的硫脲/4-噻唑烷酮/查尔酮杂化物库。使用肉汤稀释技术研究了新合成的化合物对几种细菌(金黄色葡萄球菌、蜡状芽孢杆菌、铜绿假单胞菌和肺炎克雷伯菌)和真菌(白色念珠菌和棒曲霉)的功效。从生物学评价,(E)-3-(3,4-二甲氧基苯基)-1-(4-((4-(4-乙基哌嗪-1-基)喹唑啉-2-基)氨基)苯基)prop-2 -en-1-one 被发现是抑制细菌生长最活跃的类似物(微生物抑制浓度 3.12 μg/mL)。与标准品相比,其余化合物表现出同等效力 (3.12–12.5 μg/mL)。
