Mechanistic insights into novel cyano-pyrimidine pendant chalcone derivatives as LSD1 inhibitors by docking, ADMET, MM/GBSA, and molecular dynamics simulation.

Cancer presents a formidable and complex foe, standing as one of the foremost contributors to disease-related fatalities across the globe. According to data from the Global Cancer Observatory (GLOBOCAN), projections indicate a staggering 28.4 million cases of cancer, encompassing both new diagnoses and deaths, by 2040. Therefore, developing effective and comprehensive treatment approaches for cancer patients is essential and the conventional approved treatments for cancers are associated with various harmful side effects. Our study aims to address the critical and widespread need for alternative therapies that can effectively combat cancer with minimal side effects. The present contribution outlines a targeted approach using Lysine Specific Demethylase 1 (LSD1) to evaluate novel cyano-pyrimidine pendant chalcone derivatives as potential antiproliferative agents. Two sets of novel cyano-pyrimidine pendant chalcone derivatives were produced, and molecular docking was performed on the LSD1 protein. The ligands A1 and B1 belonging to series A and B, respectively, were found to have the highest docking scores of -11.095 and -10.773 kcal/mol, in that order. The ADME and toxicity studies of the ligands showed promising responses with respect to various pharmacokinetic and physicochemical parameters. The Molecular dynamics (MD) simulation results indicated effective diffusion of both complexes inside the protein cavity, facilitated by prominent interactions with various amino acids. Additionally, the complexes displayed high relative binding free energy. The computational screening of ligands indicates that ligands A1 and B1 exhibit potential for further exploration using various
