A series of novel benzimidazole-pyridine-piperidine hybrids was synthesized in good yields and characterized
by spectral and elemental analyses. The compounds 4a-h and 5a-c were evaluated for their in vitro antibacterial activity
against gram-positive organisms viz., Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis, gramnegative
organisms viz., Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and also against fungal strains
like Candida albicans, Saccharomyces cervisiae of yeasts, Aspergillus flavus, Aspergillus niger according to the CLSI
Standard Protocol. Compound 5a showed promising activity against all tested organism excluding Bacillus subtilis when
compared to standard drugs.
一系列新型苯并咪唑-吡啶-哌啶杂化物被高效合成并通过光谱和元素分析进行了表征。化合物4a-h和5a-c在体外抗菌活性测试中,针对革兰氏阳性菌如枯草芽孢杆菌、金黄色葡萄球菌、表皮葡萄球菌,革兰氏阴性菌如大肠埃希氏菌、铜绿假单胞菌、肺炎克雷伯菌,以及酵母菌株如白色念珠菌、酿酒酵母,霉菌如黄曲霉、黑曲霉,均依据CLSI标准协议进行了评估。化合物5a与标准药物相比,显示了对除枯草芽孢杆菌外的所有测试菌株的潜在活性。
