Novel indenopyrrol-4-one derivatives as potent BRDT inhibitors: synthesis, molecular docking, drug-likeness, ADMET, and DFT studies

We synthesized new, structurally distinct series of indeno[1,2-b]pyrrol-4(1H)-ones. Effective derivatives were found by in silico screening, and our studies revealed that compound 5h exhibited good binding energies for inhibition of BRDT. In addition, DFT studies were carried out by means of the B3LYP/6-3lG basis set in the gas phase to investigate the conformation of protein-ligand interactions. The results of the investigation suggest that these compounds could be considered novel BRDT inhibitors. The pharmacokinetic and drug-like properties of the new indenopyrrol-4(1H)-one derivatives exhibited that these compounds could be represented as potential candidates for further development into anticancer-like agents. Additionally, based on the optimised structures, the optimum geometry for each of the selected molecules was developed. Then, the estimated and the experimentally determined IR vibrational frequencies for each compound were compared. The results of this comparison showed that the theoretical and experimental data were in excellent agreement, which could support the reliability of the experimental analytical data and the applicability of the mathematical model.Communicated by Ramaswamy H.
