phosphine adducts of dithiocarbamatecomplexes 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. Thermalstudies of the complexes were carried out. In
direct synthetic route for the preparation of a novel category of piperazines containing dithiocarbamate functional group. This metal-free and operationally simple approach can be applied with good to excellent yields and high selectivity. Besides, substituted bis-piperazines and piperidines containing dithiocarbamate groups were successfully prepared via the same protocol using quaternized quinuclidine
A series of 21 new analogues of C-12 dithiocarbamate andrographolide was designed and synthesized from natural andrographolide isolated from a common Thai plant, Andrographis paniculata. The reaction used to manipulate the andrographolide scaffold was conducted in one pot under mild reaction conditions. This avoided toxic catalysts and gave nearly quantitative yields of new analogues, generally without by-products and can be easily scaled -up for industrial processing. All new analogues were evaluated against nine cancer cell lines, some analogues exhibited greater selective cytotoxic activity to MCF-7 cancer cell than that of the parent andrographolide and cancer drugs.
