Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 15227-42-6, is researched, Molecular C10H10Cl2N2Pt, about The effects of single administration of an antitumor platinum compound on ornithine decarboxylase activity in certain tissues of mice bearing L1210 leukemia, the main research direction is antitumor platinum compound ornithine decarboxylase; leukemia platinum compound ornithine decarboxylase.Safety of cis-Dichlorobis(pyridine)platinum(II).

A single dose of cis-dichloro(dipyridine)platinum(II) [15227-42-6], when given to mice bearing 1-day-old L1210 leukemia, suppressed the increase of spleen and liver ornithine decarboxylase (ODC) [9024-60-6] activity which occurs concomitantly with development of the leukemia. The inhibition of ODC, the rate-limiting enzyme in polyamine synthesis, appeared to correlate with the prolonged chemotherapeutic efficacy of a single dose of the platinum complex. These observations suggest an addnl. mechanism by which platinum complexes express their antitumor actions and, in addition, support the view that polyamine synthesis and excretion patterns can be used as predictors of chemotherapeutic response.

A new single-component photocatalyst for the reduction of water to H2, a dichloro(dpbpy)platinum(II) derivative (dpbpy = 4,4′-diphenyl-2,2′-bipyridine) tethered to four pendant viologen acceptors (1), is shown to exhibit twice higher photocatalytic efficiency than the previously reported dichloro(bpy)-platinum(II) analog (2; bpy = 2,2′-bipyridine), consistent with the higher absorptivity of 1 at the metal-to-ligand charge transfer (1MLCT) band due to the larger π-conjugation in dpbpy relative to bpy.

The kinetics of oxidation of cis-[PtCl2L2] (L = py, 3-methyl-, 3- and 4-chloro-, 3- and 4-cyanopyridine) by [AuCl4]- in the presence of [NEt4]Cl and of reduction of cis-[PtCl4L2] by [NEt4]I were studied in MeCN. The rate law for the oxidation reaction was rate = k3[PtCl2L2][AuCl4-][Cl-], where k3 was unaffected by changes in L and had a value ∼100 times higher than that previously found for related phenanthrolineplatinum(II) complexes. The rate law for the reduction reaction was rate = k2[PtCl4L2][I-], where k2 was influenced by the basicity of L, as in related phenanthrolineplatinum(IV) complexes. The kinetic results were discussed in terms of σ and π interactions between the Pt and L.

Author is Giese, Bernd; Deacon, Glen B.; Kuduk-Jaworska, Janina; McNaughton, Don.

There is considerable interest in the development of novel platinum-based anticancer drugs that overcome the disadvantages associated with the widely used drug cisplatin, which are its inactivity against some types of tumors and its toxic side effects. In this study we show the suitability of normal Raman spectroscopy (NRS) and surface enhanced Raman spectroscopy (SERS), assisted by d. functional theor. (DFT) calculations, for the characterization of Pt complexes. The Pt complexes studied include the established drugs cisplatin and carboplatin, as well as five novel Pt complexes with anticancer activity. DFT calculations at the B3LYP/LanL2DZ level are a good prediction of the exptl. NRS spectra of small and medium sized Pt complexes. The use of SERS allows the investigation of Pt complexes at physiol. concentrations, and the binding strengths of the different ligands can be determined The formation of pos. charged hydrolysis products may be necessary for SERS activity. The existing group in the hydrolysis reaction can be identified.

Application In Synthesis of cis-Dichlorobis(pyridine)platinum(II). So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Electrochemical properties of MC60 (M=Pd, Pt) covered electrodes.

The formation of electroactive films containing [60]fullerene and Pd or Pt was observed for solutions with the C60 and different metal complexes, Pd(PhCN)2Cl2, [Pd(CH3CO2)2]3, Pd(CH3CO2)2, [Pt(μ-Cl)Cl(C2H4)]2, cis-PtCl2(py)2, trans-PtCl2(py)2, and PtI2(py)2. Characterization of the film compositions by IR spectroscopy, MS and XPS shows that the films contain solely C60 and metal, as well as cations of the supporting electrolyte of the growth solution, that get incorporated during the cathodic growth process. Scanning electron micrographs of the films show that these consist mainly of spheres of ∼100 nm diameter and that the film thickness can be controlled by the number of cycles used during the growth process. The films show conductivity in the potential range of growth and this conductivity is both electronic and ionic and have thus potential application in high-d. energy storage devices.
