In the past two decades, a wide variety of bioactive peptides have been discovered. Many of the heterocyclic found to exhibit antifungal, antibacterial, cytotoxic, antineoplastic, insecticidal, anti-inflammatory, tyrosinase inhibitory and melanin production inhibitory activities.Imidazole has been drawn as promising structural units in the field of medicinal chemistry. Introduction of D-amino acids and N-methylation of amino acids like tyrosine, valine, alanine etc enhanced antimicrobial activity. Hence an attempt is made towards the sythesis of 5-nitroimidazolyl-benzoic acid derivative of N-methyl amino acids and peptide using solution phase technique of peptide synthesis.
