Fludarabine (FA) and Clofarabine (FCA), two novel drugs, were studied both experimentally and theoretically. The solvation free energies of FA and FCA were calculated using different solvents, and their absorption properties were evaluated. Structural features of the drugs were characterized using spectroscopic techniques. Theoretical calculations, molecular docking analysis, and MD simulations were performed to investigate the chemical and electronic characteristics, binding affinities, and stability of the drugs.
Fludarabine (FA) and Clofarabine (FCA) two novel drugs are studied experimentally and theoretically. The solvation free energies of FA and FCA molecules have been calculated using water, ethanol, Dimethylsulfoxide, and acetonitrile solvent. Various protic and aprotic solvents are used to evaluate the absorption properties. Fourier Transform Infrared, FT-Raman and Nuclear magnetic resonance spectroscopy are used to characterize structural features of fludarabine and clofarabine. On the studied molecules, Density Functional theory (DFT) was performed to find various chemical and electronic characteristics. Molecular docking analysis employed optimized geometrical structures. Dual Fukui functions, dual local softness, and philicity were studied and discussed in extensive detail. The crystal structures of leukaemia virus protease, 2B7F, 4G0U, and 6ZTD were used to test fludarabine and clofarabine. Out of the three PDBs, 4G0U gives high binding affinity with FCA/FA during docking analysis and hence MD simulations are performed for further investigation to find the interactions and stability.
