The present invention relates to novel substituted pyrazole derivatives of the general formula (I)
in which R1, R2, R3 and A are each as defined, and to processes for their preparation and to their use as medicaments, in particular as medicaments for the treatment of cardiovascular disorders.
A pharmaceutical useful as a therapeutic agent and a preventive agent for hyperlipemia, and a pharmaceutical useful as a therapeutic agent and a preventive agent for hepatic disorders associated with cholestasis, particularly, primary biliary cirrhosis and primary sclerosing cholangitis, and a pharmaceutical useful as a therapeutic agent and a preventive agent for obesity, fatty liver and steatohepatitis are provided. A benzothiazepine or benzothiepine compound represented by the following formula (1A) having a thioamide bond and a quaternary ammonium substitutent:
A method for inhibiting ileal bile acid transporter activity in a subject, comprising administering to said subject an effective amount of a compound represented by formula (1):
Selective oxygenation of C(sp3)–Hbonds adjacent to nitrogen atoms is a highly attractive strategy for synthesizing various formamide derivatives while preserving the substrate skeletons. Herein, an environmentally benign electrochemically enabled decyanative C(sp3)–H oxygenation of N-cyanomethylamines using H2O as a carbonyl oxygen atom source is described, leading to the synthesis of a large class
与氮原子相邻的C(sp 3 )–H 键的选择性氧化是合成各种甲酰胺衍生物同时保留底物骨架的极具吸引力的策略。在此,描述了使用 H 2 O 作为羰基氧原子源对N-氰基甲胺进行环境友好的电化学脱氰 C(sp 3 )–H 氧化反应,从而以良好至优异的收率合成了一大类甲酰胺,具有在无金属和无氧化剂的条件下具有广泛的底物范围。这种电化学技术突出了将N-甲酰基轻松结合到一些重要的生物活性分子中。
