Quality Control of Diiodo(1,5-cyclooctadiene)platinum(II). Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Platinum(II) complexes of unsymmetrical, potentially bidentate ligands. Author is Anderson, Gordon K.; Kumar, Ravi.

The reactions of Ph2P(CH2)nX (n = 2, X = OMe, NMe2, SMe; n = 3, X = NMe2) with [PtX2(cod)] (X = Cl, I; cod = cycloocta-1,5-diene) are described. The tendency of the ligand to bond to the metal in a bidentate fashion is dependent on the nature of the weak donor, and on the size of the chelate ring formed. Halide abstraction by Ag+ promotes coordination of the ether function to yield [PtCl(PH2PCH2CH2OMe)2]+ and [Pt(Ph2PCH2CH2OMe)2]2+. Reactions of the former with a number of weak donor ligands were studied by 31P{1H} NMR spectroscopy. Complex mixtures were obtained with Ph2PCH2CH2SMe, and the involvement of ion-paired species is suggested in this case.

As far as I know, this compound(12266-72-7)Quality Control of Diiodo(1,5-cyclooctadiene)platinum(II) can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

A range of (2,2′:6′,2”-terpyridine)platinum(II) complexes are shown to possess antiprotozoal activity in vitro against Leishmania donovani, Trypanosoma cruzi, and Trypanosoma brucei, the causative organisms of tropical diseases leishmaniasis and trypanosomiasis. The best compounds caused 100% and 78% inhibition of growth of the intracellular amastigote forms of L. donovani and T. cruzi, resp., at a concentration of 1 μM and 100% inhibition of growth of the bloodstream trypomastigote forms of T. brucei at a concentration of 0.03 μM. The results obtained with complexes in which the fourth ligand to platinum(II) is capable of being substituted with a substitution inert hydroxyethanethiolate complex are compared. The ammine complexes show high antiprotozoal activity suggesting that the trans influence of the 2,2′:6′,2”-terpyridine ligand has a profound effect on the ease of displacement of the fourth ligand in (2,2′:6′,2”-terpyridine)platinum(II) complexes, although nonbonded interaction between the ammine ligand and the 6 and 6” hydrogens probably also weakens the ligation to Pt(II).

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) called Synthesis and structural studies of some 1,1′-dichloroferrocene derivatives of platinum(II).

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Cooperation between Cis and Trans Influences in cis-PtII(PPh3)2 Complexes: Structural, Spectroscopic, and Computational Studies, the main research direction is platinum phenyl phosphine crystal mol structure cis trans isomerism; substituent effect natural bond orbital platinum phenyl phosphine.Related Products of 12266-72-7.

The relevance of cis and trans influences of some anionic ligands X and Y in cis-[PtX2(PPh3)2] and cis-[PtXY(PPh3)2] complexes have been studied by the X-ray crystal structures of several derivatives (X2 = (AcO)2 (3), (NO3)2 (5), Br2 (7), I2 (11); and XY = Cl(AcO) (2), Cl(NO3) (4), and Cl(NO2) (13)), d. functional theory (DFT) calculations, and one bond Pt-P coupling constants, 1JPtP. The latter have allowed an evaluation of the relative magnitude of both influences. Such influences act in a cooperative way and that the cis influence is not irrelevant when rationalizing the 1JPtP values, as well as the exptl. Pt-P bond distances. In the optimized geometries, evaluated through B3LYP/def2-SVP calculations, the cis influence was not observed, except for compounds ClPh (21), Ph2 (22), and, to a lesser extent, Cl(NO2) (13) and (NO2)2 (14). A natural bond order anal. on the optimized structures has shown how the cis influence can be related to the s-character of the Pt hybrid orbital involved in the Pt-P bonds and the net at. charge on Pt. In the X-ray structures of cis-[PtX2(PPh3)2] complexes the two Pt-X and the two Pt-P bond lengths are different each other and are related to the conformation of the phosphine groups, rather than to the crystal packing, since this feature is observed also in the optimized geometries.

Compound: Diiodo(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12I2Pt, CAS is 12266-72-7, about Cytotoxicity of 2,2′:6′,2”-Terpyridineplatinum(II) Complexes against Human Ovarian Carcinoma. Author is Lowe, Gordon; Droz, Anne Sophie; Vilaivan, Tirayut; Weaver, George W.; Park, Jenny J.; Pratt, Jonathan M.; Tweedale, Lindsay; Kelland, Lloyd R..

2,2′:6′,2”-Terpyridineplatinum(II) complexes are shown to possess cytotoxicity against a number of human ovarian tumor cell lines. Many of the complexes show similar activity against cisplatin- and doxorubicin-resistant cell lines as the parental cells suggesting that there is little or no cross-resistance with cisplatin or doxorubicin. The cytotoxicity of bis[2,2′:6′,2”-terpyridineplatinum(II)] complexes is strongly dependent on the nature of the linker. Bis[2,2′:6′,2”-terpyridineplatinum(II)] complexes with a flexible linker at the 4′-position show poor cytotoxicity; by contrast bis[2,2′:6′,2”-terpyridineplatinum(II)] complexes with rigid and short linkers at platinum(II) are strikingly effective. Several of the compounds show greater cytotoxicity against human ovarian cell lines than carboplatin, the therapeutic agent currently advocated for the treatment of human ovarian cancers.
