triazolylmethyloxy quinazolines were synthesized from anthranilic acid through quinazolyl oxyacetylhydrazide intermediates. All the compounds were characterized by IR, 1H‐NMR, EI‐MS, and C, H, N analyses and evaluated for their antimicrobial activity. Docking studies on the DNA‐gyrase enzyme (1KZN) show their role in the antimicrobial activity of the molecules and explain the higher potency of compounds 6a, 6b, 8a
据报道,喹唑啉衍生物具有抗炎、镇痛、抗菌和抗癌活性。发现在喹唑啉环的第 4 位掺入“OCH2CONH2”(氧甲基脲)会影响分子的生物活性。基于这个原理,一些新的恶二唑基甲氧基喹唑啉、吡唑基乙酰氧基甲基喹唑啉、三唑基甲氧基喹唑啉由邻氨基苯甲酸通过喹唑基氧乙酰基酰肼中间体合成。所有化合物均通过 IR、1H-NMR、EI-MS 和 C、H、N 分析进行表征,并评估其抗菌活性。DNA 旋转酶 (1KZN) 的对接研究显示了它们在分子抗菌活性中的作用,并解释了化合物 6a、6b、8a、
