A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 40003-41-6, Name is 2-Bromo-4-methylthiazole-5-carboxylic acid, molecular formula is C5H4BrNO2S. In a Article£¬once mentioned of 40003-41-6, Recommanded Product: 2-Bromo-4-methylthiazole-5-carboxylic acid

Pyridine carboxamide-based inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified and optimized to a variety of topologically related scaffolds. In particular, the 2-methyl nicotinic acid scaffold was developed into inhibitors with improved biochemical (IC50-GT1b = 0.014 muM) and cell-based HCV replicon potency (EC50-GT1b = 0.7 muM). Biophysical and biochemical characterization identified this novel series of compounds as palm site binders to HCV polymerase.

A series of 1, 5-benzothiazepines were synthesized using disulfides and alpha, beta-unsaturated carbonyl or nitrile compounds as reaction substrates. After reductive cleavage of the S-S bond of disulfides, the resulting thiols were reacted with alpha,beta-unsaturated carbonyl or nitrile compounds to generated seven-membered heterocyclic compounds. In the presence of ammonium thioglycolate, the Michael reaction occurred between disulfides (1) and 4-methyl-3-penten-2-one to give 2, 2, 4-trymethyl-3H-1, 5-benzothiazepine derivatives in good yields. When ethyl acrylate or acrylonitrile was used as the Michael acceptor, 90-99% of (2-amino- phenylsulfanyl)propionitriles (3) and/or 92-99% of (2-amino-phenylsulfanyl) propionic acid ethyl esters (4) were produced. Subsequently, the 1, 5-benzothiazepine compounds 5 and 6 were obtained due to the cyclization reaction. The Japan Institute of Heterocyclic Chemistry.
