Silver-loaded TiO2 (Ag-TiO2) and acidic clay (K10 montmorillonite) composite photocatalyst has been successfully applied for the light-induced conversion of o-phenylenediamine (OPD) and its derivatives to substituted benzimidazoles with various alcohols in acetonitrile using UV-A and solar light. The influence of the various photocatalysts, solvents, and substituents on the yield and selectivity of the products has been investigated. The mechanism of photocatalysis is proposed. Loading silver on TiO2 enhances product yield and selectivity both in UV and solar light. In the presence of primary alcohols, 2-aminothiophenol forms only disulfide and hence Ag-TiO2/ clay can be used as a green catalyst for the synthesis of disulfides.

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 6344-72-5 is helpful to your research. Application of 6344-72-5

The number of collisions between reactants and catalyst is at a maximum.In a patent, 49679-45-0, name is Ethyl 3-chloroquinoxaline-2-carboxylate, introducing its new discovery. Electric Literature of 49679-45-0

We identified a new series of quinoxaline-2-carboxylic acid derivatives, targeting the human proviral integration site for Moloney murine leukemia virus-1 (HsPim-1) kinase. Seventeen analogues were synthesized providing useful insight into structure-activity relationships studied. Docking studies realized in the ATP pocket of HsPim-1 are consistent with an unclassical binding mode of these inhibitors. The lead compound 1 was able to block HsPim-1 enzymatic activity at nanomolar concentrations (IC50 of 74 nM), with a good selectivity profile against a panel of mammalian protein kinases. In vitro studies on the human chronic myeloid leukemia cell line KU812 showed an antitumor activity at micromolar concentrations. As a result, compound 1 represents a promising lead for the design of novel anticancer targeted therapies.

Piperidine, cyclohexylamine, methoxide ion and para-thiocresolate ion react with 2-chloro-3-nitroquinoxaline 1 by selectively substituting the nitro group, in contrast to be behavior of most ortho-chloronitroaromatics which loose halide when subjected to nucleophilic substitution reactions.This inversion is interpreted as being due to the lack of activation of the 2-position by the nitro group in the 3-position because of the low value of the ?-bond index between these two vertices.It is also suggested that the substitution by neutral reagents such as amines is strongly influenced by stabilizing interactions between the negatively charged nitro group and the ammonium moiety in the ? complex; this built-in solvation may be responsible for inversions in the chemoselectivity between chloro and nitro nucleofugicities.

RhoA, a member of the Rho GTPases, is involved in a variety of cellular functions and could be a suitable therapeutic target for the treatment of cardiovascular diseases. However, few small-molecule RhoA inhibitors have been reported. Based on our previously reported lead compounds, 32 new 2-substituted quinoline (or quinoxaline) derivatives were synthesized and tested in biological assays. Six compounds showed high RhoA inhibitory activities, with IC50 values of 1.17-1.84 muM. Among these, (E)-3-(3-(ethyl(quinolin-2-yl)amino)phenyl)acrylic acid (26b) and (E)-3-(3-(butyl(quinolin-2-yl)amino)phenyl)acrylic acid (26d) demonstrated noticeable vasorelaxation effects against phenylephrine-induced contraction in thoracic aorta artery rings, and compound 26b had good water solubility and showed significant in vivo efficacy, which was similar to that of 5-(1,4-diazepane-1-sulfonyl)isoquinoline (fasudil) in a subarachnoid hemorrhage-cardiovascular model. To the best of our knowledge, compound 26b is the first example of a small-molecule RhoA inhibitor with potent in vivo efficacy, which could serve as a good lead for designing cardiovascular agents.

A convenient and practical iodobenzene-catalyzed synthesis of trideuteroalkoxylated quinoxalinones has been developed under transition-metal-free conditions. The present transformation can be accomplished through C[sbnd]H/O[sbnd]H cross-dehydrogenative-coupling of quinoxalinones with deuterated alcohol. Various substrates are compatible, providing the corresponding products in moderate to good yields. A free radical pathway mechanism is advised for the transformation.
