Peptide Derivatives of 1,2-Dihydro-3-Methyl-2-Oxoquinoxaline-6-Carboxylic Acid: Synthesis and Evaluation of Antimicrobial, Antifungal and Antiviral Potential

摘要

1,2-dihydro-3-methyl-2-oxoquinoxaline-6-carboxylic acid (S1) was prepared and coupled with various amino acid tri/tetrapeptide methyl esters to afford new quinoxalopeptide derivatives (S1a - S1i). The synthesized derivatives were characterized and screened for their antibacterial, antifungal and anthelmintic activity. Furthermore, molecular docking study revealed their potential in targeting human papillomavirus (HPV-16) E6 oncoprotein.
