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

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.

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 Lamotrigine: Design and synthesis of new multicomponent solid forms, published in 2019-03-01, which mentions a compound: 1452-77-3, mainly applied to lamotrigine multicomponent solid forms; Co-crystals and salts; Diflunisal; Lamotrigine; Pyridinecarboxamides; Stability assay; Xanthines, Synthetic Route of C6H6N2O.

In this work, a crystal engineering and thermodn. based approach has been used aiming at contributing to a deeper knowledge of lamotrigine multicomponent solid forms. Two types of co-mols. have been chosen that can give rise to co-crystals with lamotrigine through different supramol. heterosynthons: the xanthines, theophylline and caffeine, and the three isomeric pyridinecarboxamides. Association with diflunisal, which may result in a salt, was also investigated. Mechanochem., differential scanning calorimetry, thermogravimetry, X-ray powder and single crystal diffraction, IR spectroscopy were the methods used. For all the systems, exploratory neat mechanochem. experiments, carried out on lamotrigine + co-mol. binary mixtures of different compositions, were not successful in promoting association From differential scanning calorimetry data and the binary solid-liquid phase diagrams, co-crystals/salts were identified as well as their resp. stoichiometry, and a methodol. of synthesis was established. For pyridinecarboxamides, mol. recognition is dependent on the position of the amide group in the pyridine ring: co-crystallization did not occur with picolinamide co-former. Both xanthines form co-crystals with lamotrigine, (1:1) with theophylline and (2:1) lamotrigine:caffeine. Addnl., the crystalline structure of a lamotrigine:theophylline 1:1 monohydrate was solved. The (1:1) lamotrigine:theophylline co-crystal converts to this monohydrate in accelerated stability tests. A (1:1) lamotrigine:diflunisal salt was identified, which proved to be stable in accelerated stability assays.

Category: tetrahydroisoquinoline. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Polar functional group-containing glycolipid CD1d ligands modulate cytokine-biasing responses and prevent experimental colitis. Author is Inuki, Shinsuke; Hirata, Natsumi; Kashiwabara, Emi; Kishi, Junichiro; Aiba, Toshihiko; Teratani, Toshiaki; Nakamura, Wataru; Kojima, Yoshimi; Maruyama, Toru; Kanai, Takanori; Fujimoto, Yukari.

The MHC class I-like mol. CD1d is a nonpolymorphic antigen-presenting glycoprotein, and its ligands include glycolipids, such as α-GalCer. The complexes between CD1d and ligands activate natural killer T cells by T cell receptor recognition, leading to the secretion of various cytokines (IFN-γ, IL-4, IL-17A, etc.). Herein, we report structure-activity relationship studies of α-GalCer derivatives containing various functional groups in their lipid acyl chains. Several derivatives have been identified as potent CD1d ligands displaying higher cytokine induction levels and/or unique cytokine polarization. The studies also indicated that flexibility of the lipid moiety can affect the binding affinity, the total cytokine production level and/or cytokine biasing. Based on our immunol. evaluation and investigation of physicochem. properties, we chose bisamide- and Bz amide-containing derivatives 2 and 3, and evaluated their in vivo efficacy in a DSS-induced model of ulcerative colitis. The derivative 3 that exhibits Th2- and Th17-biasing responses, demonstrated significant protective effects against intestinal inflammation in the DSS-induced model, after a single i.p. injection.

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.

Product Details of 1452-77-3. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Picolinamide, is researched, Molecular C6H6N2O, CAS is 1452-77-3, about Green ultrasound assisted magnetic nanofluid-based liquid phase microextraction coupled with gas chromatography-mass spectrometry for determination of permethrin, deltamethrin, and cypermethrin residues. Author is Shirani, Mahboube; Akbari-adergani, Behrouz; Jazi, Masoud Boroumand; Akbari, Ali.

Ultrasound-assisted magnetic nanofluid-based liquid-phase microextraction was coupled to GC-MS in a method for simultaneous determination of the pyrethroid insecticides permethrin, deltamethrin, and cypermethrin. A highly efficient extraction solvent called “”magnetic nanofluid (MNF)”” is introduced for preconcentration of pyrethroids. The MNF consists of magnetic multiwalled carbon nanotubes (MMWCNTs) and deep eutectic solvent. Following microextraction, the MNF was detached by an external magnet from the medium without the need for centrifugation. 2-Pyridinecarboxamide, choline chloride, and anhydrous ferric chloride were used for the synthesis of the deep eutectic solvent. The effects of pH value, volume of MNF, sonication time, sample volume, and ionic strength, type and amount of back extraction solvent were investigated. Under optimum conditions of MNF volume of 50μL, time of 5 min, 100μL acetone as back extraction solvent, NaCl concentration of 1 mol.L-1 and sample volume of 30 mL, the detection limits are 2.8, 2.7 and 2.0 ng.mL-1 for permethrin, deltamethrin and cypermethrin, resp. The linear response ranges are between 0.01 and 250 ng.mL-1, and relative standard deviations (for n = 7) are 3.5, 3.2 and 2.8%. The method was successfully applied to the determination of trace levels of permethrin, deltamethrin and cypermethrin in (spiked) milk samples.

The method of classical polarog. on a dropping Hg electrode in propylene carbonate was used to study the reduction of the isomeric complexes of Pt(IV) of type [Pt(C5H5N)2Cl2Br2] and of Pt(II) of type [Pt(C5H5N)2X2], where X = Cl, Br. The reduction of cis,cis,trans-[Pt(C5H5N)2Cl2Br2] and of cis,trans,cis-[Pt(C5H5N)2Cl2Br2] occurs according to an electrochem.-chem. mechanism during which, and following the 1-electron reduction of Pt(IV) to Pt(III), there occurs an intramol. redox process with participation of coordinated pyridine.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Ligand effects in platinum binding to DNA. A comparison of DNA binding properties for cis- and trans-[PtCl2(amine)2] (amine = NH3, pyridine), the main research direction is DNA binding platinum pyridine complex.Electric Literature of C10H10Cl2N2Pt.

The DNA binding properties of cis- and trans-[PtCl2(pyridine)2] have been examined and compared with their NH3 analogs, cis- and trans-DDP. The presence of a planar ligand reduces the rates of DNA binding but does not greatly affect the overall conformation of CT DNA, as measured by CD spectroscopy. The sequence specificity of trans-[PtCl2(py)2] includes alternating purine-pyrimidine sequences. The sequence specificity is further different between the two pyridine isomers, and the steric effects of two cis-pyridine groups are demonstrated by the appearance of relatively few binding sites in the 49-bp duplex. The effects of the pyridine ligand are further manifested by a greatly enhanced DNA-DNA interstrand crosslinking efficiency for the trans isomer, with a cross-link per adduct frequency of between 0.14 and 0.23, depending on the rb of the sample. The unwinding of closed circular pUC19 DNA by trans-[PtCl2(pyridine)2] is also more efficient than that by either DDP isomer. In contrast, little unwinding is induced by cis-[PtCl2(pyridine)2]. These results invert the standard cis/trans structure-activity relationships observed previously for [PtCl2(NH3)2]. The results are discussed with respect to the previously demonstrated effect of activation of the trans-platinum geometry using sterically hindered ligands.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 4-Chloro-4′-ethynyl-1,1′-biphenyl(SMILESS: C#CC1=CC=C(C2=CC=C(Cl)C=C2)C=C1,cas:57399-11-8) is researched.Recommanded Product: 1452-77-3. The article 《Copper-Catalyzed and Proton-Directed Selective Hydroxymethylation of Alkynes with CO2》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:57399-11-8).

An intriguing strategy for copper-catalyzed hydroxymethylation of alkynes with CO2 and hydrosilane was developed. Switched on/off a proton source, for example, t-BuOH, direct hydroxymethylation and reductive hydroxymethylation could be triggered selectively, delivering a series of allylic alcs. and homobenzylic alcs., resp., with high levels of Z/E, regio- and enantioselectivity. Such a selective synthesis is attributed to the differences in response of vinylcopper intermediate to proton and CO2. The protonation of vinylcopper species is demonstrated to be prior to hydroxymethylation, thus allowing a diversion from direct alkyne hydroxymethylation to reductive hydroxymethylation in the presence of a suitable proton source.

Although many compounds look similar to this compound(57399-11-8)Application In Synthesis of 4-Chloro-4′-ethynyl-1,1′-biphenyl, numerous studies have shown that this compound(SMILES:C#CC1=CC=C(C2=CC=C(Cl)C=C2)C=C1), has unique advantages.
