Spectroscopic, quantum chemical and molecular docking studies on 2,4-dimethoxy-1,3,5-triazine: a potent inhibitor of protein kinase CK2 for the development of breast cancer drug

ABSTRACT The theoretical calculations of the 2,4-dimethoxy-1,3,5-triazine (DMT) molecule were performed with the help of density functional theory (DFT) calculations using 6-311++G(d,p) basis set. The conformational analysis of the DMT molecule was carried out and the most stable molecular structure was predicted. The structural parameters and vibrational wavenumbers of the title molecule were also calculated. Fourier transform-infrared (FT-IR) and Fourier transform-Raman (FT-Raman) spectra of the molecule were observed and simulated. The ultraviolet-visible (UV-Vis) absorption spectra of the molecule were simulated in the gas phase as well as in the liquid phase. The frontier molecular orbitals of the molecule were simulated, which confirms the bio-active nature of the molecule. The molecular electrostatic potential surface was visualized to confirm the reactive regions of the molecule. The natural bond orbital analysis reveals the bio-activity of the molecule. The thermodynamic functions of the molecule were computed. The molecular docking analysis confirms that the title molecule could act as a potent inhibitor of protein kinase, casein kinase (CK2), which is a key protein for breast cancer. The obtained results show that the title molecule is a potential bio-active agent which may be valuable for the designing of drugs for the treatment of breast cancer.
