Synthesis, Structure, and Antibacterial Activity of 4-Imino-1, 4-dihydrocinnoline-3-carboxylic Acid and 4-Oxo-1, 4-dihydrocinnoline-3-carboxylic Acid Derivatives as Isosteric Analogues of Quinolones
The crystal structure of one analogue determined by X‐ray diffraction shows the dipolar formof the compound in the solid state. The in vitro antibacterial activity of the synthesized compounds against Gram‐positive and Gram‐negative bacteria was examined. The MIC of the most active compounds lies in the range of the first generation of quinolones such as nalidixic acid. The compounds with dichlorobenzyl
以提高其抗菌活性和抗菌谱为目的,对肉诺沙星进行化学修饰研究。合成了一系列4-亚氨基-1, 4-二氢肉啉-3-羧酸衍生物并评价了它们的体外抗菌活性。这些衍生物被设计为氟喹诺酮类的等排类似物,其特征是在 4 位存在亚胺基而不是氧代基团,在 2 位存在氮原子。 X 射线衍射测定的一种类似物的晶体结构显示固态化合物的偶极形式。检查合成的化合物对革兰氏阳性和革兰氏阴性细菌的体外抗菌活性。最活跃的化合物的 MIC 在第一代喹诺酮类药物的范围内,例如萘啶酸。
