In search for the new antimicrobial agents owing to drug resistant bacteria and fungi, a series of rationally designed aza analogs of flavones has been designed and synthesized. The design of the analogs involved incorporation of quinolone nucleus within the flavone framework keeping in view the antimicrobial potential of both the classes. The series of compounds was evaluated for the antibacterial
为了寻找由于抗药性细菌和真菌引起的新的抗菌剂,已经设计并合成了一系列合理设计的黄酮类氮杂类似物。类似物的设计涉及在黄酮骨架内掺入喹诺酮核,同时要考虑两类的抗菌潜力。评价了该系列化合物对3种革兰氏阴性细菌菌株的抗菌和抗真菌活性。大肠杆菌(MTCC 82),伤寒沙门氏菌(MTCC 1251),铜绿假单胞菌(MTCC 2642),枯草芽孢杆菌2克阳性细菌菌株(MTCC 2451),金黄色葡萄球菌(MTCC 96)和2病原性真菌菌株,白色念珠菌(MTCC 3018),热带念珠菌(MTCC)。抗菌评估的结果清楚地表明,与带有失活基团的化合物相比,带有甲氧基取代基的化合物表现出显着的抗菌特性,与在2位芳基环相连的电子因子的影响。还观察到双环,杂芳基和双环杂芳基环在类似物的第二位的位置的影响。
