Resumen:
It has been discussed in the literature that electron delocalization along the peptide backbone and side chain modulates the physical and chemical features of peptides and proteins. The structure and properties of peptides are determined by their charge-density distribution, such that the modification of its side chain plays an important role on its electronic structure and physicochemical properties. Research on Entamoeba histolytica soluble factors led to the identification of the pentapeptide Met-Gln-Cys-Asn-Ser, with anti-inflammatory in vivo and in vitro effects. A synthetic pentapeptide, Met-Pro-Cys-Asn-Ser, maintained the same anti-inflammatory actions in experimental assays. A previous theoretical study allowed proposing the Cys-Asn-Ser tripeptide (CNS tripeptide) as the pharmacophore group of both molecules. This theoretical hypothesis was recently confirmed experimentally. The objective of this work was to study the influence of the electron donor and electron withdrawing sub
