Abstract :
Introduction of D-amino acids and N-methylation of amino acids like tyrosine, valine, alanine etc enhanced antimicrobial activity. Condensation of heterocyclic moieties viz nicotinic acid, thiazole, coumarin, quinoline, furan, imidazole etc. with amino acids and peptides resulted in compounds with potent biological activities. 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. The new threonine derivatives compounds are characterized by using IR, H1NMR and mass spectroscopy.
