| Vibrational spectral analysis of 2-[(4-chlorobenzyl)sulfanyli-4-(2-methylpropy1)-6-(phenylsulfanyl)-pyrimidine-5-carbonitrile was carried out using FT-IR and FT-Raman spectroscopic techniques. The equilibrium geometry and vibrational wave numbers have been computed using density functional B3LYP method with 6-311++G(d,p)(5D,7F) as basis set. Stability of the molecule arising from hyper conjugative interactions, charge delocalization has been analyzed using NBO analysis. The nonlinear optical behavior of the title compound is also theoretically predicted. From the MEP, it is evident that the negative charge covers the C equivalent to N group and the positive region is over the phenyl and the pyrimidine rings. From the potential energy scan it is clear that the lone pairs of the sulfur atom prefer to point away from the pyrimidine ring and the C equivalent to N group resulting with two possible minimum conformations at the N4C8S1C25 angle equal nearly 0 degrees or 150 degrees. Molecular docking results suggest that the compound might exhibit inhibitory activity against GPb and may act as potential anti-diabetic compound. (C) 2014 Elsevier B.V. All rights reserved. |
