Abstract

Limonoids serve as vital secondary metabolites. Citrus limonoids show a wide range of pharmacological potential. As a result of which limonoids from citrus are of considerable research interest. Identification of new therapeutic molecules from natural origins has been widely adopted as a successful strategy in drug discovery. This work mainly focused on the high-throughput computational exploration of the antiviral potential of three vital limonoids, i.e. Obacunone, Limonin and Nomilin against spike proteins of SARS CoV-2 (PDB:6LZG), Zika virus NS3 helicase (PDB:5JMT), Serotype 2 RNA dependent RNA polymerase of dengue virus (PDB:5K5M). Herein we report the molecular docking, MD simulation studies of nine docked complexes, and density functional theory (DFT) of selected limonoids. The results of this study indicated that all three limonoids have good molecular features but out of these three obacunone exerted satisfactory results for DFT, docking and MD simulation study.
