Isolation, characterization and in silico study of propenamide alkaloids from Hymenoepmecis bicolor poison against active μ-opioid receptor

Some insects produce venoms to defend against predators and directly interact with opioid receptors. In the present study, it was identified two alkaloids in the wasp venom species Hymenoepimecis bicolor. It was demonstrated that these could act as potential inhibitors of opioid receptors through th...

Description
Summary:Some insects produce venoms to defend against predators and directly interact with opioid receptors. In the present study, it was identified two alkaloids in the wasp venom species Hymenoepimecis bicolor. It was demonstrated that these could act as potential inhibitors of opioid receptors through their robust affinity to the receptors. The interaction profile was given to opioid receptors (μOR), with 60% of targets similar to alkaloid 1, with 0.25 probability, and 46.7% of targets similar to alkaloid 2, with a probability 0.17 of affinity as a target, which is considered signaling macromolecules and can mediate the most potent analgesic and addictive properties of opiate alkaloids. Notably, both alkaloids showed −7.6 kcal/mol affinity to the morphine agonies through six residues, Gly124, Asp147, Trp293, Ile296, Ile322, and Tyr326. These observations suggest further research on opioid receptors using in vitro studies of possible therapeutic applications. Communicated by Ramaswamy H. Sarma
