N - methylated analog of Amidomycin, was synthesized by solution phase peptide synthesis using dicyclohexylcarbodiimide (DCC) as the coupling agent and triethylamine (TEA) as the base. T he structure of the compound was confirmed by IR, 1 H NMR, 13 C NMR, FABMASS and elemental analysis. T he synthesiz ed cyclic peptide was evaluated for Minimum Inhibitory Concentration (MIC) against four strains of bacteria and three strains of fungi. It was f ound to be active against both bacteria and fungi from 50 - 100 μ g.
