In an article，Which mentioned a new discovery about 887590-25-2

Starting from 11beta-HSD1 inhibitors that were active ex vivo but with Cyp 3A4 liability, we obtained a new series of adamantane ureas displaying potent inhibition of both human and rodent 11beta-HSD1 enzymes, devoid of Cyp 3A4 interactions, and rationally designed to provide long-lasting inhibition in target tissues. Final optimizations lead to SAR184841 with good oral pharmacokinetic properties showing in vivo activity and improvement of metabolic parameters in a physiopathological model of type 2 diabetes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 887590-25-2 is helpful to your research. Application of 887590-25-2

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world.148231-12-3, Name is 5,8-Dibromoquinoxaline, molecular formula is C8H4Br2N2. In a article，once mentioned of 148231-12-3

In this paper, research work focuses on the synthesis of a series of PPE-based polymers with commonly used conjugated units, including thiophene, benzo[c][1,2,5]thiadiazole (BT), benzo[c][1,2,5]selenadiazole (BSe), etc. The optical bandgaps of these polymers were tuned in the range of 2.10-2.76 eV. The order of bandgap-lowering ability of these units in PPE-derivatives is: M-3 > M-6 > M-5 > M-4 > M-9 ? M-7, M-8 > M-2. Their FRET applications in polymer solar cell and TNT detection were studied respectively, and the results indicated that all these PPE-derivatives were good candidate materials for polymer solar cells or detecting TNT in solution. Furthermore, if electron-acceptor units had structures similar to the diphenylquinoxaline in the PPE-derivatives chain, the polymers would give a better fluorescence quenching in response to TNT compound. Polymers PPE-7 and PPE-8 were chosen as representative samples to investigate their photo-oxidative stability compared with that of PPVs or PTs. The results demonstrated that both polymers PPE-7 and PPE-8 were more photo-oxidatively stable than MEH-PPV or P3HT.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 63810-80-0, Name is 2,3-Dichloro-6,7-dimethylquinoxaline, molecular formula is C10H8Cl2N2. In a Article，once mentioned of 63810-80-0

A trifluoroacetic acid promoted step-economical one-pot approach to the synthesis of furo-fused quinoxalines/pyrazines by the reaction of 2,3-dichloroquinoxalines/pyrazines with alkynes is described. The reaction involves a selective in-situ Sonogashira coupling step and a hydroxylation followed by a metal-free 5-endo-dig cyclization. Preliminary experiments show that trifluoroacetic acid acts as a source of oxygen for the oxyarylation step, and isotopic labeling studies support the proposal that the mechanistic pathway involves activation of the alkyne by the acidic medium. Various kinds of substituents are tolerated, which should prove valuable for structural and biological investigations.
