Effectiveness of Active Compounds of Herbal Plants as Aphrodisiacs Through Molecular Docking Against Human Phosphodiesterase-5 Receptors

Abstract

Based on the evaluation of side effects the use of sildenafil as a human phosphodiesterase 5 inhibitor drug (HPDE5) has prompted the search for new compounds that have the potential to be aphrodisiacs. The purpose of this study was to determine the interaction of the active compounds nilocitin, stigmasterol, protodioscin, icariin, yohimbine, and ginsenoside against the HPDE5 receptor as an aphrodisiac. The method used in this study was experimental conducted in silico. The metabolite structure is downloaded from the PubChem application, the protein is downloaded from PDB (Protein Data Bank) with the code 2H42. The result of this study is that the active compound may interact with HPDE5 receptors. The interaction that occurs results in the formation of van der waals bonds, hydrogen, carbon hydrogen, sigma, sulfur cation anions, T-shape and alkyls. The active compounds each have a sildenafil bond energy of -9.5 kcal/mol; niloticin -7.8 kcal/mol; stigmasterol -10.7 kcal/mol; protodioscin -13.1 kcal/mol; icariin -11.1 kcal/mol; yohimbine -10.1 kcal/mol and ginsenoside -12.1 kcal/mol with RMSD 0. The interaction with the HPDE5 receptor results in the formation of the same amino acid residue as the comparison ligand. The residual equation shows that the compounds have the same activity and can be predicted as aphrodisiacs
