Recommanded Product: cis-Dichlorobis(pyridine)platinum(II). Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Interaction of cis platinum(II) compounds with poly(L-glutamate). A doubly anchored spin-label and a doubly anchored chromophore-label. Author is Chao, Yen Yau H.; Holtzer, Alfred; Mastin, Stephen H..

The free-radical 4-amino-2,2,6,6-tetramethylpiperidinyl-1-oxy [14691-88-4] yields cis-Pt(ATMPO)2(NO3)2 [64716-94-5], which is used to label poly(L-glutamate) (I), poly(L-aspartate) (II), and poly(L-lysine) (III). Labeling occurs by displacement of nitrate by polymer side chains. EPR spectra of oriented films of labeled I are strongly anisotropic; several arguments suggest that the major cause is g anisotropy. Spectra of solutions, in several solvents, of labeled I are also anisotropic and monitor the helix-coil transition and polymer aggregation. Since monofunctional, side-chain labels show only isotropic motions, Pt must be bifunctionally anchored to adjacent carboxylates, requiring the label to follow backbone segmental motions. With shorter side chains (II) adjacent double anchoring is impossible; with longer side chains (III), flexibility reduces coupling to backbone motion; in each, therefore, spectra are isotropic. Chromophoric compounds, particularly cis-Pt(bipy)(H2O)2][NO3]2 [64800-95-9], are similarly used. Bifunctional attachment is evidenced by the absence of base-induced UV spectral shifts (characteristic of attachment of OH- to Pt) shown by label alone, and by similarity of the spectra of labeled polymer and labeled oxalate. Induced CD appears for α helix in the region of the chromophore π-π* bands; transition to random coil drastically reduces this CD. With extensively labeled polymer differences in the course of the helix-coil transition as monitored by CD in the backbone region with that monitored in the chromophore region show that the label stabilizes its attached helical residue. A study of Corey-Pauling-Koltun models and extant theories suggests that the induced CD arises by coupling of the carboxylate π-π* and the bound chromophore 1B1 elec. transition moments.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Metathesis reactions between heavy D8 fluorides and I(III)-pyridine complexes.Related Products of 15227-42-6.

The reaction between trans-[AuF2(pyridine)2]+ and [PhI(pyridine)2]2+ results in the formation of PhIF2 and [Au(pyridine)4]3+. Investigation of the reaction pathway using model Pd and Pt analogs of the gold complex indicate the most likely mechanism is attack by the Au-F onto the I(III), rather than a redox process. This demonstrates that the Au(III)-F fragment can behave in a nucleophilic manner even in a relatively electron poor cationic complex.

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, Mutation Research called Prophage induction and mutagenicity of a series of antitumor platinum(II) and platinum(IV) coordination complexes, Author is Mattern, I. E.; Cocchiarella, L.; Van Kralingen, C. G.; Lohman, P. H. M., which mentions a compound: 15227-42-6, SMILESS is [Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2, Molecular C10H10Cl2N2Pt, Formula: C10H10Cl2N2Pt.

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.

There is still a lot of research devoted to this compound(SMILES：[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2)Formula: C10H10Cl2N2Pt, and with the development of science, more effects of this compound(15227-42-6) can be discovered.

cis-[PtL2Cl2] (L = Et2NOH) was prepared by the reaction of K2PtCl4 with L. cis-[PtL2Cl2] does not react with amines (NH3, pyridine, Et2NOH) and L does not react with cis-[PtA2Cl2] (A = NH3, py). cis-[PtL2Cl2] is monoclinic, space group C2, a 7.569(2), b 12.384(7), c 15.428(2) Å, β 100.00(2)°, Z = 4, R = 0.0287. One L coordinates to Pt through the N atom whereas the other is in the zwitterionic form and coordinates through the O atom. The low reactivity of cis-[PtL2Cl2] in substitution reactions is explained on the basis of H bonding and agostic interactions due to which the axial positions in the square planar complexes are blocked against nucleophilic attack.

Platinum(II) complexes. Author is Cleare, Michael J.; Hoeschele, James D..

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.
