In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Mechanism of cis-trans photoisomerization of dichlorodipyridineplatinum,(II), published in 1971, which mentions a compound: 15227-42-6, mainly applied to dichlorodipyridineplatinum photoisomerization; complex dichlorodipyridineplatinum photoisomerization; platinum dichlorodipyridine photoisomerization, Product Details of 15227-42-6.

The photochem. behavior of cis- and trans-Pt(py)2Cl2 in CHCl3 solutions has been investigated using 313 nm light. The cis isomer undergoes 2 simultaneous photoreactions, one being an intramol. photoisomerization process (Φisom ∼0.04) and the other a photodissociation reaction involving the pyridine ligand (Φdiss ∼ 0.025). This latter photoreaction provides an intermol. path for the cis → trans isomerization since its products (namely, free pyridine and Pt-containing species) recombine thermally to give cis- and trans-Pt(py)2Cl2 in a 2:1 ratio. The trans isomer undergoes photoisomerization and pyridine release but with much lower quantum yields (∼0.001). Qual. results concerning the photochem. behavior of the above complexes in MeOH solutions upon 254 or 313 nm irradiation are also reported.

Although many compounds look similar to this compound(15227-42-6)Product Details of 15227-42-6, numerous studies have shown that this compound(SMILES:[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2), has unique advantages.

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 Thermal isomerization of complex platinum(II) compounds, published in 1972, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, Computed Properties of C10H10Cl2N2Pt.

The thermal cis-trans isomerization of [PtA2I2] complexes, where A = NH3, MeNH2, EtNH2, pyridine, was studied by derivatography. The heat of isomerization is 1-7 kcal/mole. trans-[Pt(R2SO)ACl2]-type complexes melt upon heating and isomerize in the melt. The isomerization reaction proceeds through formation of a tetrahedral intermediate.

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 Platinum compounds with anti-tumor activity, the main research direction is platinum compound tumor structure; platinum compound antitumor structure.Application In Synthesis of cis-Dichlorobis(pyridine)platinum(II).

Ten Pt coordination complexes with different ligands, comprising both Pt(II) and Pt(IV) complexes of which the cis-compounds all possessed at least some antitumor activity and the trans-compounds were inactive, were tested as to their effect on cell survival and the induction and repair of DNA damage in cultured Chinese hamster cells (CHO). The Pt-compounds were divided in 3 groups on the basis of their cytotoxicity. The compounds with high cytotoxicity were also active antitumor drugs, but a clear correlation between cytotoxicity and antitumor activity was not observed All compounds inhibited semi-conservative DNA synthesis and induced DNA repair replication. No induction of DNA single strand breaks and DNA cross-links was detected. However, the occurrence of alkali labile sites in the DNA of treated CHO cells demonstrated the induction of unidentified DNA bases damages. The cis-compounds were more mutagenic than the trans-compounds

Author is Lucier, Bryan E. G.; Reidel, Alex R.; Schurko, Robert W..

Multinuclear solid-state NMR (SSNMR) experiments were performed on cisplatin and four related square-planar compounds The wideband uniform rate smooth truncation-Carr-Purcell-Meiboom-Gill (WURST-CPMG) pulse sequence was used in NMR experiments to acquire 195Pt, 14N, and 35Cl ultra-wideline NMR spectra of high quality. Standard Hahn-echo and magic-angle spinning 195Pt NMR experiments are also performed to refine extracted chem. shielding (CS) tensor parameters. Platinum magnetic shielding (MS) tensor orientations are calculated using both plane-wave d. functional theory (DFT) and standard DFT methods. The tensor orientations are highly constrained by mol. symmetry elements, but also influenced to some degree by intermol. interactions. 14N WURST-CPMG experiments were performed on three compounds and elec. field gradient (EFG) parameters (the quadrupolar coupling constant, Cq, and the asymmetry parameter, ηq) are reported. First principles calculations of the 14N EFG tensor parameters and orientations and affirm their dependence on the local hydrogen bonding environment. 35Cl WURST-CPMG experiments on cisplatin and transplatin are reported, using two different static magnetic fields to extract EFG and CS tensor parameters, and 35Cl EFG tensor magnitudes and orientations are predicted using 1st principles calculations Transverse (T2) relaxation data for all nuclei were used to study heteronuclear dipolar relaxation mechanisms, as well as the nature of the local hydrogen bonding environments.

Cycloaddition reaction of the carbene N2CHCO2Et to norbornene in the presence of Rh(II) gave 95% tricyclic esters I (R = CO2Et), which were reduced with LiAlH4 to give 63% I (R = CH2OH) (II). Kinetic resolution of II by oxidative insertion with Pt(py)2Cl2 gave 93% complex III (R = CH2OH) and its isomer, which underwent stereospecific acid-catalyzed ring expansion to give 70-80% complexes IV (R1 = H, Me, CHO; L = py) and their isomers. Ligand substitution with P(OMe)3 gave 100% IV [L = P(OMe)3], which underwent reductive elimination on heating to give 80-90% III (R = OR1).

We’ll tell you more about this compound (cas:15227-42-6).

cis-[PtL2L12]2+ (L = guanosine, 9-methylhypoxanthine, L1 = Me-substituted 1,3-propanediamines, py, α-picoline, 2,2′-bipyridine, 1,2-bis(pyridin-2-yl)ethane) were prepared and studied by NMR. Rotation of L about their Pt-N7 bonds is fast on the NMR time scale, when no Me groups are present on the nitrogens of the 1,3-propanediamine ligands. Rotation is slow when 2 Me groups are present on 1 N of a 1,3-propanediamine chelate. A single Me group on a N hardly seems to interfere with this rotation. Coordinated pyridines do not hinder rotation. In compounds containing 2-methylpyridine ligands, the rotation of the pyridines is slow at room temperature, but becomes fast at higher temperatures Rotation of L, however, is fast on the NMR time scale from -30 to +90°. In compounds containing 1,2-bis(pyridin-2-yl)ethane, rotation of L is slow at low temperatures, but becomes fast at room temperature Furthermore, the results obtained with these compounds show that the purines are preferentially oriented in a head-to-tail arrangement.

Eleven Pt compounds with N donor ligands (aminocyclopentane, aminocyclohexane, pyridine, etc.), previously tested for antitumor activity, were studied for induction of prophage λ and for mutagenicity in the Ames assay, with various strains of Salmonella. The compounds included cis and trans isomers of Pt(II) and Pt(IV) complexes and were tested with and without metabolic activation. All the cis compounds elicited prophage induction, whereas the trans compounds were inactive. Mutagenicity was found only in strains containing the R factor, indicating that SOS-type repair processes are required for the conversion of initial DNA lesions into mutations. Mutation induction was also influenced by the excision-repair process. The 2 trans compounds were not, or only slightly, mutagenic; all other compounds were mutagenic in at least one strain, exhibited a 2-20-fold increase over the spontaneous background level. Addition of liver homogenate had no significant effect on the number of mutants. One compound induced exclusively frameshift mutations. The other mutagenic compounds induced frameshift mutations as well as base-pair substitutions. Seven compounds were more mutagenic for the repair-proficient than for the repair-deficient strains; only one showed the opposite effect. Apparently, for mutagenicity testing of Pt compounds, repair-proficient strains are more sensitive indicators. The differences in response of the various strains toward the compounds suggest the formation of different DNA lesions and(or) a selective action of repair processes on these lesions. In general, a good qual. correlation was observed between prophage-inducing capacity, mutagenicity in bacterial and mammalian cells and antitumor activity.

Category: tetrahydroisoquinoline. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Mass spectrometry of cis-platin in urine. Author is Sumino, Kimiaki; Mio, Takaya; Yamamoto, Ryoji; Ishigami, Joji; Kamidono, Sadao; Hamami, Gaku.

The mass spectra of cisplatin  [15663-27-1] and its analogs are presented. A urine sample of a cancer patient treated with cisplatin was extracted with 0.1N-HCl and then washed with COMe2/CHCl3. The component containing Pt was eluted with 2N-HBr using an ion exchange chromatog. technique. The mass spectrum of the component showed the change from Cl-type to Br-type as the unchanged type of carrier ligand. Thus, mass spectrometry may be a useful method to elucidate the action mechanism of cisplatin.
