Author is Goswami, Abir; Gaikwad, Sudhakar; Schmittel, Michael.

Enzymes are encoded with a gamut of information to catalyze a highly selective transformation by selecting the proper reactants from an intricate mixture of constituents. Mimicking biol. machinery, two switchable catalysts with differently sized cavities and allosteric control are conceived that allow complementary size-selective acyl transfer in an on/off manner by modulating the effective local concentration of the substrates. Selective activation of one of two catalysts in a mixture of reactants of similar reactivity enabled upregulation of the desired product.

Author is Guo, Jianpeng; Yu, Wenying; Cai, Guiping; Zhang, Wenda; Li, Shanshan; Zhu, Jiawen; Song, Dongmei; Kong, Lingyi.

Persistent activated STAT3 has a striking correlation with cancer development and inhibition of STAT3 signaling pathway is a novel therapeutic way for human cancers. Among STAT family, STAT1 and STAT3 play opposite roles in tumorigenesis. However, the discovery of selective STAT3 inhibitors is still challenging to date. In this study, a series of small-mol. (MW<500) benzensulfanilamide derivatives were designed to selectively suppress STAT3 activation for anti-cancer treatment. The most potent compound 11 inhibited both overexpressed and IL-6 induced STAT3 phosphorylation, whereas 11 displayed little effect on the phosphorylation of other STAT isoforms STAT1, STAT5, demonstrating 11 was a selective STAT3 inhibitor. Meanwhile, 11 dismissed STAT3 DNA binding activity and colony formation. In addition, 11 elevated the ROS level and induced apoptosis of cancer cells. Furthermore, 11 effectively suppressed tumor growth in an in vivo mouse-xenograft model.

Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about Effect of triethylamine/anhydrous HF ratio on the anodic polarization of nickel in acetonitrile media. Author is Noel, M.; Suryanarayanan, V.; Krishnamoorthy, S..

The effect of the addition of 0.5M, 1.5M, 3M and 4.5M triethylamine in acetonitrile containing 3M anhydrous HF (AHF) on the anodic polarization behavior of Ni was studied using cyclic voltammetry and chronoamperometry. The structure and composition of the film formed on a nickel electrode in these media was studied using SEM and XRD. The severe dissolution noticed in aqueous HF solution decreases significantly in acetonitrile containing AHF. Addition of small molar ratios of triethylamine leads to enhanced uniform dissolution due to the simultaneous presence of H+ as well as fluoride ions. Further addition of triethylamine suppresses the HF concentration This leads to anodic dissolution at a significantly more pos. potential. Dissolution and film growth occurs as individual crystallites. In all cases, NiF2·4H2O and another phase is formed on the electrode surface.

Electric Literature of F2H8NiO4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms.

A systematic study of x-ray intensity ratios of the K-series lines was made on compounds of Ni and Co to examine the influence of chem. state and 0.6 and 1.2 T external magnetic fields on energy-dispersive x-ray fluorescence anal. The samples were excited by 22.69 keV x-rays emitted from a Cd-109 radioisotope source and characteristic K x-rays emitted from the samples were counted by an Si(Li) detector. For B = 0, the present exptl. results were compared with the exptl. and theor. data in literature. The results demonstrate a clear dependence of the Kβ/Kα intensity ratios on the chem. state of the element in the sample and values of external magnetic field.

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 Highly Enantioselective Hydrogenation of Quinoline and Pyridine Derivatives with Iridium-(P-Phos) Catalyst, published in 2010-04-30, which mentions a compound: 221012-82-4, mainly applied to quinoline dihydroquinolinone enantioselective hydrogenation iridium phosphino bipyridine catalyst; tetrahydroquinoline hexahydroquinolinone asym synthesis, COA of Formula: C38H34N2O4P2.

The use of a chiral iridium catalyst generated in situ from the (cyclooctadiene)iridium chloride dimer, [Ir(COD)Cl]2, the P-Phos ligand [4,4′-bis(diphenylphosphino)-2,2′,6,6′-tetramethoxy-3,3′-bipyridine] and iodine for the asym. hydrogenation of 2,6-substituted quinolines and 2-substituted 7,8-dihydroquinolin-5(6H)-ones is reported. The catalyst worked efficiently to hydrogenate a series of quinoline derivatives to provide chiral 1,2,3,4-tetrahydroquinolines in high yields and up to 96% ee. The hydrogenation was carried out at high S/C (substrate to catalyst) ratios of 2000-50000, reaching up to 4000 h-1 TOF (turnover frequency) and up to 43000 TON (turnover number). The catalytic activity is found to be additive-controlled. At low catalyst loadings, decreasing the amount of additive I2 was necessary to maintain the good conversion. The same catalyst system could also enantioselectively hydrogenate 2-substituted 7,8-dihydroquinolin-5(6H)-ones, affording the chiral hexahydroquinolinone derivatives in nearly quant. yields and up to 99% ee. Interestingly, increasing the amount of I2 favored high reactivity and enantioselectivity in this case. The high efficacy and enantioselectivity enable the present catalyst system of high practical potential.

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: 945400-80-6, is researched, Molecular C7H5BrN2S, about Discovery of 2-aryl and 2-pyridinylbenzothiazoles endowed with antimicrobial and aryl hydrocarbon receptor agonistic activities, the main research direction is aryl pyridinylbenzothiazole hydrocarbon receptor antimicrobial agonistic activity; Agonism; Ah receptor; Antibacterial; Antibiofilm; Antifungal; Benzothiazole.Quality Control of 2-Bromobenzo[d]thiazol-6-amine.

Benzothiazole is a privileged scaffold in medicinal chem. present in diverse bioactive compounds with multiple pharmacol. applications such as analgesic, anticonvulsant, antidiabetic, anti-inflammatory, anticancer and radioactive amyloidal imagining agents. We reported in this work the study of sixteen functionalized 2-aryl and 2-pyridinylbenzothiazoles as antimicrobial agents and as aryl hydrocarbon receptor (AhR) modulators. The antimicrobial activity against Gram-pos. (S. aureus and M. luteus) and Gram-neg. (P. aeruginosa, S. enterica and E. coli) pathogens yielded MIC ranging from 3.13 to 50μg/mL and against the yeast C. albicans, the benzothiazoles displayed MIC from 12.5 to 100μg/mL. All compounds showed promising antibiofilm activity against S. aureus and P. aeruginosa. The arylbenzothiazole 12 displayed the greatest biofilm eradication in S. aureus (74%) subsequently verified by fluorescence microscopy. The ability of benzothiazoles to modulate AhR expression was evaluated in a cell-based reporter gene assay. Six benzothiazoles (7, 8-10, 12, 13) induced a significant AhR-mediated transcription and interestingly compound 12 was also the strongest AhR-agonist identified. Structure-activity relationships are suggested herein for the AhR-agonism and antibiofilm activities. Furthermore, in silico predictions revealed a good ADMET profile and druglikeness for the arylbenzothiazole 12 as well as binding similarities to AhR compared with the endogenous agonist FICZ.

There is still a lot of research devoted to this compound(SMILES：NC1=CC=C2N=C(Br)SC2=C1)Quality Control of 2-Bromobenzo[d]thiazol-6-amine, and with the development of science, more effects of this compound(945400-80-6) can be discovered.
