N-(2-[2-(1H-Indol-2-ylcarbonyl)hydrazinyl](oxo)acetyl}phenyl)acetamides (5a–h) and N-[2-(2-[2-(acetylamino)phenyl](oxo)acetyl}hydrazinyl)-2-oxoethyl]-1H-indole-2-carboxamides (5i–l) were synthesized and characterized with different analytical tools. N-Acetylisatines 4a–d were subjected to ring opening at their C2 carbons with the aid of different indole-bearing hydrazides 3a,b and 7 to afford the
N-(2-[2-(1H-Indol-2-ylcarbonyl)hydrazinyl](oxo)acetyl}苯基)乙酰胺 (5a–h) 和 N-[2-(2-[2-(乙酰氨基)苯基] ](oxo)acetyl}hydrazinyl)-2-oxoethyl]-1H-indole-2-carboxamides (5i-l) 被合成并用不同的分析工具表征。借助不同的含吲哚酰肼 3a、b 和 7,N-乙酰丝氨酸 4a-d 在其 C2 碳上进行开环,得到相应的乙醛酰胺 5a-l。借助抑菌圈直径 (DIZ) 和最小抑菌浓度 (MIC) 测定对一组革兰氏阳性菌和革兰氏阴性菌以及某些真菌菌株,评估了目标化合物 5a-l 的抗菌活性。抗菌药物筛选显示金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌、和白色念珠菌是对合成化合物 5a-l 最敏感的微生物。此外,化合物 5c 和 5h 分别是金黄色葡萄球菌和白色念珠菌最活跃的同源物。分子对接研究揭示了化合物
