In addition to that the available literature survey stimulated our interest to obtain structural information, optimized geometry of ligand HNMAMQ, and its complexes by computing the minimum satiric energy and the theoretical physical parameters, such as bond length and bond angles using MM2CS Chem 3D Ultra 11.0 version molecular modeling program; these models are necessary to obtain a constant, more precise picture of the biological active molecule at the atomic level and furthermore provide new insights that can be used to design novel therapeutic agents.
