substituted acetylated nicotinic acid derivatives by sequential transformation involving formation of hydrazide, Schiff’s base and finally acylated oxadiazole derivatives. The synthesized compounds were characterized by spectroscopic techniques and evaluated in vitro for the antimicrobial, antifungal, as well as antitubercular activity. Among all the synthesized derivatives, compounds 6b, 6d, 6e, 6g, and
摘要通过依次转化酰肼,席夫碱和最后酰化的恶二唑衍生物,将烟酸转化为不同的取代的乙酰化烟酸衍生物。合成的化合物通过光谱技术进行表征,并在体外评估其抗微生物,抗真菌和抗结核活性。在所有合成的衍生物中,化合物6b,6d,6e,6g和6j对枯草芽孢杆菌具有优异的抗菌活性。化合物6d,6j和化合物6b,6f,6h,和6i在500 µg / mL的浓度下分别表现出对白色念珠菌和黑曲霉的最大抑制作用。6f,6g和6d表现出的抗结核活性,最小抑菌浓度(MIC)分别为1.2、3.1和7.8 µg / mL。通过分子对接通过Autodock Vina对合成的化合物进行了研究,以评估它们在相应蛋白质上的相互作用。此外,还评估了合成衍生物对人红细胞表面形态以及溶血的影响。结果表明溶血毒性的程度较小。 图形概要
