Synthesis, Antimicrobial Evaluation, DFT, in Silico-Docking, and ADMET Investigations of Novel Chromene-based 2,4-Thiazolidinediones.

Abstract

Three series of thiazolidinedione (TZD) derivatives (5a-f, 7a-f, and 9a-f) were prepared efficiently. Afterward, the synthesized candidates' antibacterial efficacy against both gram-positive and gram-negative bacteria was assessed. Compounds 7c, 7d, and 7f had values comparable to that of ampicillin, a reference antibiotic, whereas compounds 5c, 5d, and 7e exhibited the greatest values (23.0 ± 1.0, 27.7 ± 0.6, and 20.0 ± 1.0, respectively) against gram-positive bacteria (Staphylococcus aureus). The optimal structure of the produced molecules was determined by DFT computing. To assess the binding energy and elucidate the interaction between the potential candidates and different proteins, silico-docking is employed. ADMET analysis to assess the synthesized compounds' toxicity, metabolism, excretion, distribution, and absorption.
