Drug Design, In Silico-Profiling of New Pyrrole Derivatives: Promising Anticancer Agents Against Acute Myeloid Leukemia

Abstract

Molecular docking simulation and synthesis of five compounds of N2, N4-bis (2-(4-substituted phenyl)-4-oxothiazolidin-3-yl)-3,5-dimethyl-1H-pyrrole-2,4-dicarboxamide was carried out to evaluate their theoretical binding affinities, targeting acute myeloid leukemia (AML). The chemical structure of the molecules was accurately drawn using ChemDraw Professional 19.1 software. The designed compounds were evaluated for their selectivity towards FLT3's ATP pocket (PDB ID:6JQR) in comparison with the reference ligand (Gilteritinib) by using GOLD suite from the Cambridge Crystallographic Data Centre (CCDC) software (Version 2021.2.0). All the designed compounds exhibited good binding energies with the receptor active pocket and had promising activity. Compounds 2E and 3E showed the highest PLP Fitness (83.30, 80.86 respectively) and it is higher than that of Gilteritinib (71.91). In-silico ADME and drug-likeness studies were performed by using the Swiss ADME server. The results showed that most of the designed compounds expected to be absorbed from the GIT. Compounds 2B-E have high expected GI absorption. All the investigated compounds have no predicted BBB penetration. Additionally, compounds 2A, 2C, 2D, and 3A are not a substrate to P-gps which may indicate a lower expected incidence of resistance by cancer cells in vitro studies. Finally, all of the investigated compounds are not considered to inhibit CYP1A2 enzyme, except for compounds 2A and 3D.
