Provided herein are methods of treating or ameliorating hypercholemia or a cholestatic liver disease by administering to an individual in need thereof a therapeutically effective amount of an Apical Sodium-dependent Bile Acid Transporter Inhibitor (ASBTI) or a pharmaceutically acceptable salt thereof. Also provided are methods for treating or ameliorating a liver disease, decreasing the levels of serum bile acids or hepatic bile acids, treating or ameliorating pruritis, reducing liver enzymes, or reducing bilirubin comprising administering to an individual in need thereof a therapeutically effective amount of ASBTI or a pharmaceutically acceptable salt thereof.
drug development program and consider the enzymatic approach in parallel to a conventional chemical synthesis of the human metabolites of the bile acid reabsorption inhibitor SAR548304. Chemical preparation of N,N-di-desmethyl metabolite was realized by a seven-step synthesis starting from a late precursor of SAR548304 and included among others palladium catalysis and laborious chromatographic purification
非特异性过氧化酶(UPOs,EC 1.11.2.1)已被证明是稳定的氧转移生物催化剂,可用于依赖H 2 O 2的药物转化。我们已经将UPOs应用于药物开发计划中,并考虑了与胆汁酸重吸收抑制剂SAR548304的人类代谢产物的常规化学合成同时进行的酶促方法。N,N-二-去甲基甲基代谢物的化学制备是通过从SAR548304的较晚前体开始的七步合成实现的,其中包括钯催化和费力的色谱纯化,总收率为27%。酶促方法揭示了马勒斯米乌斯·罗图拉(Marasmius rotula)的UPO特别适用于药物的选择性N-脱烷基反应,使我们能够通过一锅转化制备两种人的代谢产物,其总收率为66%N,N-二-去甲基代谢产物和49%的N-单-去甲基化化合物两个分开的动力学控制反应。
