In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Antitumor activity of Group VIII transition metal complexes. I. Platinum(II) complexes, published in 1973, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, Name: cis-Dichlorobis(pyridine)platinum(II).
A wide variety of Pt(II) complexes were studied for antitumor activity against Sarcoma 180 in female mice. In general only neutral complexes exhibited activity, whereas charged species were inactive and relatively nontoxic. A series of complexes of the type cis-[PtA2X2] (where A2 is either 2 monodentate or 1 bidentate amine ligand and X2 is either 2 monodentate or 1 bidentate anionic ligand) were studied with A and B being systematically varied. At least 10 potentially active antitumor drugs were identified, including cis-dichlorbis(methylamine)platinum(2+) [15273-32-2], diamminepropanedioatoplatinum(2+) [38780-43-7], and (1,2-ethanediammine-N,N’)(2-methylpropanedioato)platinum(2+) [41575-97-7]. The trans isomers were inactive in comparison with active cis complexes, so the presence of cis-reactive ligands seems to be a necessary parameter for antitumor activity. Complexes with highly reactive ligands such as cis-[Pt(NH3)2 (H2O)2](NO3)2 were highly toxic. Pd(II) complexes analogous to the active Pt(II) compounds were themselves inactive.
As far as I know, this compound(15227-42-6)Name: cis-Dichlorobis(pyridine)platinum(II) can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
