Antimicrobial screening and molecular docking of synthesized 4,6-di(1H-indol-3-yl)-1,6-dihydropyrimidin-2-amine

Abstract

A variety of medicinal compounds, including 4,6-di(1H-indol-3-yl)-1,6-dihydropyrimidin-2-amine, were synthesized through a single-step, multicomponent, stepwise reaction. In this reaction, a mixture of 1H-indole-3-Carbaldehyde, 1-(1H-indol-3-yl) ethanone and guanidine nitrate in ethanol was refluxed. The synthesized compounds were characterized using ¹H NMR and ¹³C NMR studies and their antimicrobial activities against Escherichia coli, Staphylococcus aureus, Aspergillus niger and Aspergillus flavus were evaluated. Molecular docking analysis revealed specific amino acid residues (LEU704, GLY708, LEU707, GLN711, MET749, PHE764, VAL746, MET787, MET745, LEU873, HIS874, VA; 903, MET742, ILE898, MET895, ILE899, TRP741, THR877, P HE 876, LEU701, MET780) are involved in the interaction between androgen receptor and ligand. The optimal interaction and docking score were observed (7.0 ​kcal/mol).
