Study on Molecular Anti-tumor Mechanism of 2-Thiohydantoin Derivative based on Molecular Docking and Bioinformatic Analyses

Abstract

Objective: Several methods for synthesizing 2-thiohydantoin derivatives have been devised and exploited, and they have found widespread application as antioxidants, antimicrobials, antivirals, and anticancer agents. As a result, we tried to understand the underlying processes of the 2-thiohydantoin derivative's anti-LIHC activity. Methods: We predicted the anticancer mechanism of N-(4-oxo-5-(2-oxo-2-(p-tolylamino)ethyl)-3-phenyl-2-thioxoimidazolidin-1-yl)benzamide as a derivative of 2-thiohydantoin by utilizing molecular docking and molecular dynamic simulation. Furthermore, based on the results of molecular dynamic modelling, we employed bioinformatics to anticipate the immunotherapy of this molecule in the tumor microenvironment (TME) of Liver Hepatocellular Carcinoma (LIHC) patients. Next, we examined how this derivative affected proliferation, cell cycle progression, reactive oxygen species production, and apoptosis in HepG2 cancer cells. Results: Substantially, our investigation revealed that the IC50 value was 2.448 µM and that it arrested the cell cycle of HepG2 in the S phase. Furthermore, molecular docking and dynamics studies revealed a worthy interaction of this compound with AKT1 and CDK2 proteins. Considerably, AKT1 and CDK2 have negative affinity energies of -10.4 kcal/mol and -9.6 kcal/mol, respectively. Several bioinformatic tools were used in this investigation to provide insight into the future clinical application of this derivative as a novel candidate to target immune cells such as macrophages, neutrophils, eosinophils, and CD8+ T cells. Conclusion: The relevance of this 2-thiohydantoin derivative was demonstrated by our experimental tests, docking studies, and bioinformatics analysis, and it may be investigated as a lead molecule for anticancer medicines, notably as AKT1 and CKD2 inhibitors.

Metformin as a promising target for DPP4 expression: computational modeling and experimental validation

“…A simulation interaction figure was used to comprehensively investigate the MD simulation data. The root mean square deviation (RMSD) of the DPP4-metformin complex, the DPP4’s root mean square fluctuation (RMSF), the DPP4-ligand interaction figure, the interacting amino acid residues with the ligand in each trajectory frame, and the trajectory of different ligand properties were all investigated in comparison to sitagliptin as the control [ 17 , 19 ].…”

Development of a novel tumor microenvironment-related radiogenomics model for prognosis prediction in hepatocellular carcinoma

“…Accumulating research has highlighted the essential role of the tumor microenvironment (TME) in the progression of HCC ( 5 - 7 ). The TME is mainly composed of recruited immune cells and stromal cells that interact with cancer cells to promote the process of proliferation by resisting cell apoptosis and evading immune surveillance, ultimately affecting tumor metastasis, treatment effectiveness, and survival ( 6 - 8 ).…”
