Wang, Hai; Wang, Liang; Wang, Sai; Dong, Xue; Zhang, Jian; Xiao, Feng-Shou published the article 《Aerobic Activation of C-H Bond in Amines Over a Nanorod Manganese Oxide Catalyst》. Keywords: aerobic activation amine nanorod manganese oxide catalyst; amide preparation green chem.They researched the compound: Picolinamide( cas:1452-77-3 ).Application of 1452-77-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1452-77-3) here.

The development of heterogeneous catalysts for the synthesis of pharmaceutically relevant compounds is always important for chem. research. Here, we report a selective aerobic oxidation of aromatic and aliphatic amines to corresponding amides over a nanorod manganese oxide (NR-MnOx) catalyst. The kinetic studies reveal that the NR-MnOx catalyzed amine-to-amide reaction proceeds the oxidative dehydrogenation of the amines into nitriles, followed by hydrolysis of nitrile into amides. The NR-MnOx exhibits fast kinetics and high selectivities in these steps, as well as hinders the byproduct formation. More importantly, the NR-MnOx catalyst is stable and reusable in the continuous recycle tests with water as a sole byproduct, exhibiting superior sustainability and significant advancement to outperform the traditional amide production route in acidic or basic media with toxic byproducts.

Different reactions of this compound(Picolinamide)Application of 1452-77-3 require different conditions, so the reaction conditions are very important.

Category: tetrahydroisoquinoline. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Anisotropic and magnetic properties in non-metal and non-radical organic aggregates of tri-substituted phenyl derivatives. Author is Tun Nur Iskandar, Nur Amanina Juniasari; Guan-Yeow, Yeap; Maeta, Nobuyuki; Ito, Masato M.; Nakamura, Yoshiyuki; Gas, Katarzyna; Sawicki, Maciej.

A new series of tri-substituted Ph derivatives containing an aromatic imine unit and biphenyl ester possessing various numbers of carbon atoms at the terminal alkoxy chain, OCnH2n+1 (n = 7-12), along with a lateral o-ethoxy substituent have been successfully prepared and characterized by CHN microanal. along with spectroscopic techniques (FTIR, 1H- and 13C-NMR). The texture observation under polarized light revealed that all the soft condensed materials exhibited an enantiotropic nematic (N) phase. The current studies have shown that the mesomorphic behavior is greatly influenced by the length of the alkoxy chains wherein the thermal stability of a tri-substituted Ph derivative will decrease if the terminal alkoxy chain is increased from n = 7 to 12. For the first time, these materials which do not possess any magnetic species in their structure, demonstrate magnetic interaction through naked eye observation as well as quant. measurement using a SQUID magnetometer.

The platinum(II) organoamides [Pt(NRCH2)2L2] (L = pyridine (py), R = p-HC6F4, C6F5, p-IC6F4, p-ClC6F4, p-C6F5C6F4; L = 4-methylpyridine, R = p-HC6F4) and [Pt(NRCH2CH2NR’)(py)2] (R = p-HC6F4, R’ = C6F5, p-BrC6F4, or p-MeC6F4) inhibit the growth of murine L1210 leukemia cells in culture with ID50 values for continuous exposure in the range 0.6-2.7 μM. Representative complexes are also active against L1210 cells in 2-h pulse exposures, as well as against the cisplatin-resistant variant L1210/DDP and human colonic carcinoma cell lines HT 29 and BE. Three complexes [Pt(NRCH2)2L2] (R = p-HC6F4, C6F5, or p-IC6F4) have good activity (T/C ≥ 180%) against P388 leukemia in mice, and all other compounds tested are active except when R = p-C6F5C6F4, L = py. Although the mol. basis of the biol. activity of these complexes is not known, the observation of good activity for amineplatinum(II) compounds with no hydrogen substituents on the nitrogen donor atoms introduces a new factor in the anticancer behavior of platinum(II) complexes.

Quality Control of 3-(2,5-Dichloropyrimidin-4-yl)-1-(phenylsulfonyl)-1H-indole. 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: 3-(2,5-Dichloropyrimidin-4-yl)-1-(phenylsulfonyl)-1H-indole, is researched, Molecular C18H11Cl2N3O2S, CAS is 882562-40-5, about Discovery and resistance mechanism of a selective CDK12 degrader. Author is Jiang, Baishan; Gao, Yang; Che, Jianwei; Lu, Wenchao; Kaltheuner, Ines H.; Dries, Ruben; Kalocsay, Marian; Berberich, Matthew J.; Jiang, Jie; You, Inchul; Kwiatkowski, Nicholas; Riching, Kristin M.; Daniels, Danette L.; Sorger, Peter K.; Geyer, Matthias; Zhang, Tinghu; Gray, Nathanael S..

Cyclin-dependent kinase 12 (CDK12) is an emerging therapeutic target due to its role in regulating transcription of DNA-damage response (DDR) genes. However, development of selective small mols. targeting CDK12 has been challenging due to the high degree of homol. between kinase domains of CDK12 and other transcriptional CDKs, most notably CDK13. In the present study, the rational design and characterization of a CDK12-specific degrader, BSJ-4-116 (I), is reported. BSJ-4-116 selectively degraded CDK12 as assessed through quant. proteomics. Selective degradation of CDK12 resulted in premature cleavage and poly(adenylation) of DDR genes. Moreover, BSJ-4-116 exhibited potent antiproliferative effects, alone and in combination with the poly(ADP-ribose) polymerase inhibitor olaparib, as well as when used as a single agent against cell lines resistant to covalent CDK12 inhibitors. Two point mutations in CDK12 were identified that confer resistance to BSJ-4-116, demonstrating a potential mechanism that tumor cells can use to evade bivalent degrader mols.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: cis-Dichlorobis(pyridine)platinum(II)(SMILESS: [Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2,cas:15227-42-6) is researched.Electric Literature of C6H6N2O. The article 《ESR of hot ions: low spin platinum(III) complex ions produced by γ-irradiation》 in relation to this compound, is published in Bulletin of the Chemical Society of Japan. Let’s take a look at the latest research on this compound (cas:15227-42-6).

Tervalent Pt complex ions were observed by ESR upon γ-irradiation of both bivalent and quadrivalent complexes. From their g-values, the tervalent complex ions can be classified into 2 types, one axially sym. and the other orthorhombic, the former having typical g-values of 2(g‖) and 2.4(g.perp.), and the latter a g1-value slightly lower than the free electron value of 2.0023. The hyperfine interaction due to 195Pt is 1 order of magnitude larger than that in Co complexes with 3d7 low spin configuration, indicating that the configuration interaction involving 6s-orbital is more important than that for 3d transition metal complexes involving 4s-orbital, and that 5d electrons penetrate deeply into inner shells, resulting in core polarization.

Structure-activity studies with 17 Pt-containing complexes showed a correlation between the ability of these complexes to inhibit cell division in corn roots and their known antitumor activities. For the more active compounds C90 (90% suppression of root growth rate) for 3 days was 3 × 10-6M, close to the corresponding amount for highly active inhibitors of other chem. classes. Possible use of the root growth rate to study the biol. activity of Pt-containing complexes is suggested. Structure-activity relations were discussed.

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 Redox-active films formed by electrochemical reduction of solutions of C60 and platinum complexes, published in 2002-07-31, which mentions a compound: 15227-42-6, mainly applied to redox active film electrochem reduction solution fullerene platinum complex; pyridine chloro platinum complex ferrocene electroreduction redox active film, Quality Control of cis-Dichlorobis(pyridine)platinum(II).

Electroreduction of a toluene-acetonitrile (4:1 volume/volume) solution of C60 and cis-Pt(py)2Cl2 in the presence of 0.10M tetra(n-butyl)ammonium perchlorate as supporting electrolyte produces a black, redox active film that coats the electrode surface. This film retains its redox activity when transferred to an acetonitrile solution that contains only the supporting electrolyte, 0.10M tetra(n-butyl)ammonium perchlorate. The film was characterized by IR spectroscopy, laser desorption mass spectrometry, and XPS spectroscopy. The formation of this film is dependent on the platinum complex used as precursor and on the potential range used during film growth. No film growth is observed when Pt(bipy)Cl2, Pt(py)2I2, cis-Pt(PPh3)2Cl2 or trans-Pt(py)2Cl2 were used as precursors, but {Pt(μ-Cl)Cl(C2H4)}2 is a useful precursor which allows film growth at less neg. potentials. Chem. prepared C60Pt1 is also electrochem. active when precipitated on a platinum electrode. The formation of an electroactive film from the electroreduction of C70 and cis-Pt(py)2Cl2 is also reported.
