Abstract

Dermestes maculatus is a very important pest of smoke-dried fish that destroys the flesh, eating away the muscles, and leaving the skeletons when cured fish are stored for long period. This necessitates the idea of establishing an alternative repellant from natural plant products. In this article, compounds of Capsicum annum will be studied against repellent protein NDS2 of D. maculatus. The compounds present in C. annum. were docked against The NADH dehydrogenase subunit 2 (NDS2) protein of D. maculatus. PyRx-Python prescription 0.8 was used to identify binding affinities of compounds against the proteins. The results we obtained from molecular docking show that among 48 molecules of natural origin from C. annuum was downloaded in SDF format from the NCBI PubChem database. Six molecules are the best compounds observed through molecular docking and some hydrogen bonding and hydrophobic interactions are proposed as the efficacy from C. annuum on a repellent protein of D. maculatus. The molecular docking was performed to establish efficacy and binding affinity of ligands from C. annum on the repellent protein of D. maculatus. ADMET analysis is performed to establish the possible toxicity of the ligands.  Importantly, all six natural compounds present in C. annum.  may be more potent in new insecticide against NSD2 in D. maculatus but needs further experimental research.
