This study used in silico molecular docking approach to investigate whether phytochemicals from Indian spices and medicinal plants can be used as alternative therapeutic agents to synthetic drugs.
Background: The recent outbreak of the novel SARS-CoV-2 across the globe and the absence of specific drug against this virus lead the scientific community to look into some alternative indigenous treatments. India as a hub of Ayurvedic and medicinal plants can shed light on its treatment using specific active bio-molecules from these plants. Objectives: Keeping our herbal resources in mind, we were interested to inquire whether some phytochemicals from Indian spices and medicinal plants can be used as alternative therapeutic agents in contrast to synthetic drugs. Materials and methods: We used in silico molecular docking approach to test whether bioactive molecules of herbal origin such as hyperoside, nimbaflavone, ursolic acid, 6-gingerol, 6-shogaol and 6-paradol, curcumin, catechins and epigallocatechin, alpha-Hederin, piperine could bind and potentially block the M(pro)enzyme of the SARS-CoV-2 virus. Results: Ursolic acid showed the highest docking score (-8.7 kcal/mol) followed by hyperoside (-8.6 kcal/mol), alpha-Hederin (-8.5 kcal/mol) and nimbaflavone (-8.0 kcal/mol). epigallocatechin, catechins, and curcumin also exhibited high binding affinity (Docking score -7.3, -7.1 and -7.1 kcal/mol) with the M-pro. The remaining tested phytochemicals exhibited moderate binding and inhibitory effects. Conclusion: This finding provides a basis for biochemical assay of tested bioactive molecules on SARS-CoV-2 virus. (c) 2021 The Authors.
