non-bile acid FXR agonists that introduce a bicyclic nortropine-substituted benzothiazole carboxylic acid moiety onto a trisubstituted isoxazole scaffold. Herein, we report the discovery of 1 (tropifexor, LJN452), a novel and highly potent agonist of FXR. Potent in vivo activity was demonstrated in rodent PD models by measuring the induction of FXR target genes in various tissues. Tropifexor has advanced
法尼醇X受体(FXR)是一种核受体,可作为胆汁酸代谢和信号转导的主要调节剂。FXR的激活抑制胆汁酸的合成并增加胆汁酸的结合,转运和排泄,从而保护肝脏免受胆汁积聚的有害影响,从而导致人们对FXR作为治疗胆汁淤积和非酒精性脂肪性肝炎的治疗靶标产生了浓厚的兴趣。我们确定了一系列新型的强效非胆汁酸FXR激动剂,该激动剂可将双环的奥氮平取代的苯并噻唑羧酸部分引入三取代的异恶唑支架上。在此,我们报告1的发现(tropifexor,LJN452),一种新型且高效的FXR激动剂。通过测量各种组织中FXR靶基因的诱导,在啮齿类动物PD模型中证明了体内活性很强。Tropifexor已进入NASH和PBC患者的2期人类临床试验。
