Molecular Dynamic simulation of HIV-۱ Protease, Integrase and Reverse- transcriptase with Delta-۹-tetrahydrocannabinol and Curcumin as two herbal ligands

The HIV-۱ virus has three important enzymes: protease, reverse transcriptase, and integrase, which are essential for vital functions. The Acquired immunodeficiency syndrome (AIDS) virus causes a significant number of deaths annually. Herbal drugs, are inexpensive, with minimal side effects, and have been used for many years alongside conventional medicine. In fact, herbal medicine forms the basis of modern pharmacology. In this study, we investigated the potential of two herbal compounds, Curcumin (CRC) and Delta-۹-Tetrahydrocannabinol (THC), as inhibitors of HIV-۱. After conducting ۱۰۰ nanoseconds (ns) of molecular dynamics (MD) simulations for systems involving each of these three proteins in the presence of the ligands, we analyzed the simulated systems. The results, including root-mean-square deviations (RMSD), radius of gyration (Rg), root-mean-square fluctuation (RMSF), solvent accessible surface area (SASA), dictionary of secondary structure of proteins (DSSP), and g_mmpbsa, indicate that both ligands can bind to the active sites of the proteins and inhibit HIV-۱ activity. These MD simulation results suggest that both CRC and THC are effective inhibitors of HIV-۱.
