Synthesis and biological activity of a novel series of 4-[2'-(6'-nitro)benzimidazolyl]benzoyl amino acids and peptides.

A series of new 4-[2'-(6'-nitro)benzimidazolyl]benzoyl amino acids and peptides have been synthesized by coupling the 4-[2'-(6'-nitro)benzimidazolyl]benzoic acid with amino acid methyl esters/dipeptides using DCC as the coupling agent. All the synthesized compounds were found to exhibit potent anthelmintic activity along with moderate antimicrobial activity.
