Structural optimization and in vitro profiling of N-phenylbenzamide-based farnesoid X receptor antagonists
摘要:
Activation of the nuclear farnesoid X receptor (FXR) which acts as cellular bile acid sensor has been validated as therapeutic strategy to counter liver disorders such as non-alcoholic steatohepatitis by the clinical efficacy of obeticholic acid. FXR antagonism, in contrast, is less well studied and potent small molecule FXR antagonists are rare. Here we report the systematic optimization of a novel class of FXR antagonists towards low nanomolar potency. The most optimized compound antagonizes baseline and agonist induced FXR activity in a full length FXR reporter gene assay and represses intrinsic expression of FXR regulated genes in hepatoma cells. With this activity and a favorable toxicity-, stability- and selectivity-profile it appears suitable to further study FXR antagonism in vitro and in vivo.

A photocatalytic approach for carbonisotopeexchange is reported. Utilizing [13C]CO2 and [14C]CO2 as primary C1 sources, this protocol allows the insertion of the desired carbonisotope into phenyl acetic acids without the need for structural modifications or prefunctionalization in one single step. The exceptionally mild conditions required for this traceless transformation are in stark contrast
报道了用于碳同位素交换的光催化方法。利用[ 13 C] CO 2和[ 14 C] CO 2作为主要的C1来源,该方案可将所需的碳同位素插入苯基乙酸中,而无需在单个步骤中进行结构修饰或预功能化。这种无痕转化所需要的异常温和的条件与先前要求使用苛刻的热条件的方法形成了鲜明的对比。
