Screening of Reverse Transcriptase Inhibitor from Moringa oleifera Bioactive Compound through In Silico Study Againts HIV-1

Human immunodeficiency virus type 1 (HIV-1) from the retrovirus family can trigger opportunistic diseases of the immune system or AIDS. In these conditions the immune system fails due to infection with bacteria, protozoa, fungi, and other viruses. HIV-1 has several enzymes consisting of reverse transcriptase (RT), integrase (INT), & protease (PR), all of which play an important role in the replication process. Reverse transcriptase plays a role in the formation of HIV-1 cDNA in several stages consisting of lysyl tRNA having a binding site, RT then adds a nucleotide to synthesize cDNA to the non-coding or U5 and R (repeat) region of the viral RNA. RT activity has a crucial role in viral replication and is very likely to be a target in drug design. This study aims to reveal the molecular mechanism of compounds from Moringa oleifera to be antiviral for HIV-1 through a bioinformatics approach. Kaempferitrin and β-sitosterol from Moringa oleifera are predicted to be HIV-1 antiviral agents. Both compounds can produce more negative binding affinity and weak bond interactions. This indicates the stability of the binding interaction that triggers the inhibitory activity.
