DFT, hirshfeld and molecular docking studies of a hybrid compound - 2,4-Diamino-6-methyl-1,3,5-triazin-1-ium hydrogen oxalate as a promising anti -breast cancer agent.

The six-membered heterocyclic ring - 1,3,5-triazine and its derivatives have garnered a lot of attention because they're good bioactive herbicides, cancer agents, and other things. One such triazine derivative, 2,4-diamino-6-methyl-1,3,5-triazin-1-ium hydrogen oxalate (DMTHO), was produced in this work, and the structure was optimised using density functional theory's B3LYP functional and the basis set 6-31++G (d,p). Additionally, the chemical underwent in-depth research using molecular docking analysis, Hirshfeld, and density functional theory. The electron densities distribution in the atoms is provided by natural orbital analysis, which also characterises the chemical bonding and reaction behaviour of the compound. The calculated HOMO and LUMO energies indicate that charge transfer occurs inside the molecule. Chemical reactivity traits including HOMO-LUMO energy gaps, softness, total energy, chemical hardness, electronic chemical potential, and electrophilicity of bioactive substances have all been subjected to analytical investigation. Total dipole moment (μ) and first-order hyperpolarizability (β) measurements for the investigated chemical indicate that DMTHO may exhibit microscopic nonlinear optical (NLO) behaviour with nonzero values. A quantitative description about intermolecular interactions in the produced crystal is provided by the Hirshfeld surface analysis. Further docking studies of the compound have been performed and the results reveals that the compound inhibit the breast cancer related protein - casein kinase (CK2) - and the possibility of developing as a potential anti breast cancer lead.
