Triple Inhibitor Mechanism of Antiretroviral from Sambucus nigra Phytochemical through Screening Docking

Abstract

Human immunodeficiency virus type 1 (HIV-1) has a higher infectious nature than HIV-2 because of the genetic drift mechanism. Several HIV-1 strains such as A, B, C, D, E, F, G, H, & J were obtained from Africa, Asia, Europe, Australia, and America. Endemic cases of HIV-1 are often found and HIV-2 is very rare, therefore the development of antiretroviral drugs is currently focused on treating HIV-1 infection5. Research on HIV-1 vaccines is still in the research phase and some patients are only taking antiretrovirals to survive. Sambucus nigra L. is used by the community for traditional medicine such as influenza A, B, C and SARS-CoV-2 infectious diseases. There are no research reports related to the potential of Sambucus nigra L. as an antiretroviral in the treatment of HIV-1 infection and the specific molecular mechanisms that explain it, therefore this research is important for the discovery of alternative antiretroviral drugs from natural materials. The in silico method used in this study consists of Sambucus nigra L. compounds retrieval, HIV-1 protein preparation, molecular docking, and 3D visualization. Sambucus nigra L. can have inhibitory activity on three enzymes of HIV-1 such as protease (PR), reverse transcriptase (RT), integrase (INT) through naringenin and Cyanidin-3,5-diglucoside compounds. Both compounds have more negative binding energy, form stable binding interactions in the target domain, and trigger inhibitory activity.
