Concerning the Baker's Yeast (Saccharomyces cerevisiae) Mediated Reduction of Nitroarenes and Other N-O Containing Functional Groups
摘要:
Nitro- and nitrosoarenes can be reduced using baker's yeast (Saccharomyces cerevisiae) under two distinct sets of conditions, one of which is in fact a well established non-enzymic process. In order to clarify reports in the literature a comparison of the two methods has been made. (C) 1997 Elsevier Science Ltd.

Starting from 1 (MEN14268), a selectivetachykinin NK2 receptor antagonist with an interesting in vitro pharmacological profile, a family of numerous antagonists was obtained through an optimization process focused on iterated structural modifications. The effects of the introduction of a wide variety of substituents on the lipophilic aromatic part of the molecule and the modulation of the structural constraint
The present invention relates to a compound of the formula ##STR1## and the pharmaceutically acceptable salts thereof wherein W is a tricyclic heterocyclic ring system; which is an .alpha.-1 adrenergic antagonist and is useful in the treatment of BPH; also disclosed are .alpha.-1 antagonist compositions and a method for antagonizing .alpha.-1 receptors and treating BPH.
The nucleophilicaromaticsubstitution for heteroatom through electrochemical oxidation of the intermediate sigma-complexes (Meisenheimercomplexes) in simple nitroaromatic compounds is reported for the first time (NASX process). The studies have been carried out with hydride, cyanide, fluoride, methoxy, and ethanethiolate anions and n-butylamine as a nucleophile, at the cyclic voltammetry (CV) and
Certain tricyclic thioxanthone-10,10-dioxide compounds each of which is substituted in the 1-,2-,3- or 4-position by a carboxyl or (5-tetrazolyl) group and each of which is optionally substituted in the 5-,6-,7- or 8-position by a second carboxyl or (5-tetrazolyl) group or a substituent selected from cyano, halogen, nitro, alkyl, alkoxy, acyl, amino, acylamino, thioalkyl, alkylsulphinyl and alkylsulphonyl, as well as salts, and optionally substituted esters and amides of the carboxyl substituted compounds and alkyl derivatives of the tetrazolyl substituted compounds, are useful for the relief or prophylaxis of allergic conditions.
