Several substituted-quinazolin-3(4H)-ones 8—11ad were synthesized by condensation of 2-chloro-N-(4-oxo-substituted-quinazolin-3(4H)-yl)-acetamides with various substituted imidazoles through one pot reaction. Elemental analysis, IR, 1H-NMR and mass spectral data confirmed the structure of the newly synthesized compounds. Synthesized quinazolin-4-one derivatives were investigated for their antitubercular, antibacterial and antifungal activities. Some of the tested compounds showed good antitubercular activity. None of the synthesized compounds showed significant antibacterial and antifungal activity.
通过 2-氯-N-(4-氧代-取代-喹唑啉-3(4H)-基)-乙酰胺与各种取代咪唑的一锅反应缩合合成了多种取代-喹唑啉-3(4H)-酮 8-11ad。元素分析、红外光谱、1H-NMR 和质谱数据证实了新合成化合物的结构。对合成的喹唑啉-4-酮衍生物进行了抗结核、抗菌和抗真菌活性研究。一些测试化合物显示出良好的抗结核活性。合成的化合物均未显示出明显的抗菌和抗真菌活性。
