Palladium(II) complexes of 2-acylpyridines. The crystal structure of dibromo bis(phenyl-2-pyridyl ketone)palladium(II)

Investigating the isolation and interconversion of two diastereoisomers in an octahedral system

Two diastereoisomers of bis(2-benozylpyridine-O,N)dichloridonickel(ii) have been prepared, and experimentally and theoretically studied.

In vitro antitumour and antibacterial studies of some Pt(IV) dithiocarbamate complexes

A few Pt(IV) complexes of the type [Pt(L)(2)Cl(2)] [where L=morpholine dithiocarbamate (L(1)), aniline dithiocarbamate (L(2)), N-(methyl, cyclohexyl) dithiocarbamate (L(3)) and N-(ethyl, cyclohexyl) dithiocarbamate (L(4))] were synthesized. The complexes have been characterized by elemental analysis, molar conductance, IR, electronic, (1)H and (13)C NMR spectroscopic studies. The ligands found to act in monobasic bidentate fashion. Cyclicvoltammetric studies, antibacterial and in vitro antitumour studies were also carried out.

Triphenyl phosphine adducts of platinum(IV) and palladium(II) dithiocarbamates complexes: a spectral and in vitro study

Triphenyl phosphine adducts of dithiocarbamate complexes of platinum(IV) and palladium(II) of the type [Pt(L)2PPh3Cl2] and [Pd(L)2PPh3] [L: morpholine dithiocarbamate (L1), aniline dithiocarbamate (L2) and N-(methyl, cyclohexyl) dithiocarbamate (L3)] were prepared and characterized by elemental analysis, electronic, IR, 1H NMR and 13C NMR spectral studies. Thermal studies of the complexes were carried out. In vitro antitumor activity has been screened towards human adenocarcinoma cell lines and showed significant inhibition even at very low concentration.

Palladium(II) complexes of 2-acetylpyridine N(4)-methyl, N(4)-ethyl and N(4)-phenyl-thiosemicarbazones. Crystal structure of chloro(2-acetylpyridine N(4)-methylthiosemicarbazonato) palladium(II). Synthesis, spectral studies, in vitro and in vivo antitumour activity

The reactions of 2-acetylpyridine N(4)-methyl, (HAc4Me) N(4)-ethyl (HAc4Et) and N(4)-Phenyl (HAc4Ph) thiosemicarbazone with palladium(II) were studied. The ligands and the palladium(II) complexes have been characterized by spectroscopic techniques. The structure of [Pd(Ac4Me)Cl] has been determined by single-crystal x-ray diffraction. The protonation constants of HAc4Me and HAc4Et, Ka1 and Ka2, were determined by spectrophotometry. The effect of palladium compounds on DNA synthesis of P388 and L1210 cell cultures is also reported. Some of these compounds increased the life span of mice bearing tumors.
