Abstract

Heterocyclic compounds are the greatest invention by the scientists in the present scenario. Now-a days they are the ultimate goal for solving several health complexities. Presence of hetero atoms in a molecule as pharmacophore is responsible for wide variety of therapeutical activity. Objective of this work is to improvement of humble and relaxed method for generation of 2-substituted benzimidazole derivatives. It involves insertion of aromatic aldehyde into the 2nd position of benzimidazole nucleus. Which results a number of derivatives. Each derivatives were interpreted through IR spectroscopy & evaluated for antimicrobial & anthelmintic activity. Antimicrobial activity was confirmed by disc diffusion methods. Minimum zone of inhibition (7 mm) was found in case of compound, 2C (E.coli) & Maximum zone of inhibition (14 mm) was found in case of compound 2D (S.aureus) followed by 12 mm in case of 2B (E.coli). All derivatives also found to possess anthelmintic activity when we compare with the a standard drug albendazole.

Keywords: Derivatives, Synthetic, Disc diffusion, anthelmintic.
