AbstractGold complexes that could act as antitumor agents have attracted great attention. Heterocyclic compounds and their metal complexes display a broad spectrum of pharmacological properties. The present study reports the preparation and characterization of four novel gold(I) complexes containing tertiary phosphine and new ligands 5-adamantyl-1,3-thiazolidine-2-thione, 3-methyladamantane–1,3,4-oxadiazole-2-thione

extracellular GSH was also investigated. In general, mononuclear complexes containing thiazolidine–adamantane ligands were more cytotoxic than oxadiazole–adamantane derivatives. PtT complex proved to be as active as cisplatin. Dinuclear compounds were considered inactive to cells in evaluated conditions, due to their high stability with ligands in a chelated and bridged way. Results suggest that GSH cannot

The optimized molecular structure, vibrational frequencies, corresponding vibrational assignments of 5-(Adamantan-1-yl)-3-[(4-fluoroanilino)methyl]-2,3-dihydro-1,3,4-oxadiazole-2-thione are investigated experimentally and theoretically using Gaussian09 software package. Potential energy distribution of normal modes vibrations was done using GAR2PED program. The HOMO and LUMO analysis are used to determine the charge transfer within the molecule. The stability of the molecule arising from hyper-conjugative interaction and charge delocalization has been analyzed using NBO analysis. The calculated geometrical parameters are in agreement with the XRD data. The calculated first hyperpolarizability is high and the title compound is an attractive candidate for further studies in non-linear optical applications. To estimate the chemical reactivity of the molecule, the molecular electrostatic potential is calculated for the optimized geometry of the molecule. (C) 2014 Elsevier B.V. All rights reserved.

The optimized molecular structure, vibrational frequencies, corresponding vibrational assignments of 5-(adamantan-1-yl)-3-anilinomethy1-2,3-dihydro-1,3,4-oxadiazole-2-thione have been investigated experimentally and theoretically. The geometrical parameters are in agreement with XRD data. The stability of the molecule arising from hyper-conjugative interaction and charge delocalization has been analyzed using NBC analysis. The frontier molecular orbital analysis is used to determine the charge transfer within the molecule. As can be seen from the MEP map of the title molecule, the negative region are mainly localized over the C=S and the CH2 group attached to the oxadiazole ring and the maximum positive region is localized near the NH group. The first and second order hyperpolarizability values are also calculated theoretically. The title compound forms a stable complex with PPAR alpha as is evident from the binding affinity values and the results suggest that the compound might exhibit inhibitory activity against PPARc( and this may result in development of new anti-diabetic (Type 2) agents.
