| Résumé: | Copyright © 2020. Published by Elsevier Masson SAS. Abscisic acid (ABA) although complicated and expensive to produce, plays an important role in signalling responsible for regulation of developmental manifestations such as seed maturation and surviving through stress conditions. Hence, development of cost effective molecules with minimal side effects that mimic the functions of ABA is the need of the hour. In this agreement, we screened a series of 27 in-house synthesized 3-methyleneisoindolin-1-one molecules over three ABA receptors (PYR1, PYL1, and PYL3). The commercial ABA agonist Pyrabactin was taken as a standard ligand in this study. The top three molecules for each receptor were selected and further evaluated to estimate the dynamical contribution and complex stability via Molecular Mechanics-Poisson Boltzmann surface area calculations. Two molecules (Mol26 and Mol25) showed higher binding free energy and stable complex conformation for PYL3 in comparison to Pyrabactin. This study revealed the structural basis of the binding mechanism of 3-methyleneisoindolin-1-one molecules with ABA receptors. Mol26 and Mol25 were identified for the development of specific PYL3 agonists with a vast potential in agriculture to accentuate the ABA like action in plants |
