An efficient three-component, one-pot protocol is described for the synthesis of biologically interesting 2-(benzylideneamino)-N-(7-chloroquinolin-4-yl)benzohydrazide derivatives from isatoic anhydride, 7-chloro-4-hydrazinylquinoline and aromatic and/or hetero aromatic aldehydes under catalyst free condensation by using water as reaction media. All synthesized compounds were evaluated for their antimycobacterial
描述了一种有效的三组分一锅操作规程,可用于从Isatoic酸酐,7-氯-4-肼基喹啉和芳香族化合物合成生物学上令人感兴趣的2-(苄叉氨基)-N-(7-氯喹啉-4-基)苯并酰肼衍生物和/或杂芳醛在无催化剂的条件下通过用水作为反应介质进行缩合。评估所有合成的化合物对结核分枝杆菌(MTB)的抗分枝杆菌活性和对正常VERO细胞系的细胞毒性活性。合成的化合物具有0.78至25μM的最小抑菌浓度(MIC)。在测试的化合物中,4c,4o,4r和4u表现出有希望的抑制活性(MIC =3.12μM)。化合物4h和4i脱颖而出,其MIC值分别为0.78和1.56μM。
