RESUMEN
Studies on the bioactive phytochemicals found in traditional medicinal plants are growing. This study focuses on Rauvolfia tetraphylla L. and its unique bioactive chemical composition. Previous research has demonstrated the plant's antimicrobial properties due to this composition. In this study, however, we also aim to investigate the antiviral properties of the plant. Rauvolfia tetraphylla L. has long been used for medicinal purposes. It is primarily located in Mexico, Central America, the West Indies, and northern South America. Along with checking out its in-silico SARS-CoV-2 activity, current work also evaluates the leaf extracts qualitative phytochemical, antioxidant, and cytotoxicity properties. While several conventional procedures were employed in the bio active compounds and phytochemical study that identified multiple phytochemicals, compounds derived from plants will be the most effective substitution with unfavorable side effects. The focus of this work is on in silico analysis, which determines the experimental plants activity against SARS-CoV-2 using molecular docking and pharmacokinetic analysis. We identified 20 phytochemical compounds from the GC-MS data of the plant, out of these 12 compounds failed to meet ADMET properties and the remaining 8 compounds passed TOPKAT Ames Mutagenicity. These compounds were docked against one important protein 3CLpro (PDB ID: 7DPV) that is implicated in the development of SARS-CoV-2. Docking studies have demonstrated binding results with maximum score and three compounds showed promising results. The results of this study highlighted the potential efficacy of (E,E,E,E,E,E)-()-2,6,10,15,19,23-hexamethyltetracosa-1,6,10,14,18,22-hexaen-3-ol, α-Tocospiro A, and α-Tocopherol. Furthermore, a thorough examination of the in-silico data indicates that the leaf has the potential to be a powerful source of medication and an efficient therapy in the future.
