Abstract

This study explains the vibration and interaction of three pharmaceutically active hydrazine derivatives, (E)-3-((2-(2,5-difluorophenyl)hydrazono)methyl)-4H-chromen-4-one (DFH), (E)-3-((2-(4-(trifluoromethyl)phenyl)hydrazono)methyl)-4Hchromen-4-one (TMH), and (E)-3-((2-(3,5-bis(trifluoromethyl)phenyl)hydrazono)methyl)-4H-chromen-4-one (BPH) using theoretical approach. The trend in chemical reactivity and stability of the studied compounds was observed to show increasing stability and decreasing reactivity and this was obtained from orbital energies. The effect of bromine and chlorine atoms, instead of fluorine atoms, is also noted. Surface analysis on the covalent bond was attained by ELF and LOL analysis. Biological activities were predicted using molecular docking studies. Docking results were analyzed with standard drugs, 5-fluorouracil/piperine. Antitumor activity of hydrazine derivativeswas found to be higher than reference ones. Molecular dynamics (MD) simulation was performed for 100 ns to validate the stability behavior of hydrazine derivatives with the dual specificity threonine tyrosine kinase (TTK) protein. RMSD, RMSF, Rg, SASA, and intermolecular analysis of DFH, TMH, and BPH with threonine tyrosine kinase forms stable ligand-protein interactions. The molecular and predictive biological properties of three pharmaceutically active hydrazine derivatives which can be helpful to researchers in future experimental validation through in vitro and in vivo studies.
