A series of novel benzimidazole-pyridine-piperidine hybrids were 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, gram-negative organisms viz., Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and also against fungal strains like Candida albicans, Saccharomyces cervisiae of yeasts, Aspergillus flavus, Aspergillus niger was done according to CLSI Standard Protocol. Compound 5a showed promising activity against all tested organism exclude Bacillus subtilis when compared to standard drugs.
