Potassium-competitiveacidblockers (P-CABs) constitute a new therapeutic option for the treatment of acid-related diseases that are widespread and constitute a significant economical burden. Enantiomerically pure tetrahydrochromenoimidazoles were prepared using the readily available candidate 4 (BYK 405879) as starting material or the Noyori asymmetric reduction of ketones as key reaction. A comprehensive
钾竞争性酸阻滞剂(P-CAB)构成了治疗与酸有关的疾病的新的治疗选择,这些疾病与疾病相关的疾病广泛且构成重大的经济负担。使用容易获得的候选物4制备对映体纯的四氢色氮咪唑(BYK 405879)作为起始原料或Noyori酮的不对称还原是关键反应。建立了关于5-羧酰胺和8-芳基残基对体外活性,Ghosh Schild大鼠体内酸抑制和对hERG通道的亲和力影响的综合SAR。此外,通过瘘管犬的24 h pH测量,检查了最有希望的目标化合物的抗分泌作用的功效和持续时间,与Ghosh Schild大鼠相比,观察到了明显不同的SAR。鉴定了几种与候选物4具有可比性的四氢色氮咪唑。
