Definitions
- the present invention relates to FXR receptor agonists, pharmaceutically acceptable salts thereof, esters thereof and stereoisomers thereof, pharmaceutical preparations containing the same, and compounds, pharmaceutically acceptable salts thereof, esters thereof and the like Stereoisomers are useful in the preparation of a medicament for the treatment and/or prevention of FXR receptor-mediated non-alcoholic fatty liver disease, primary biliary cirrhosis, lipid metabolic disorders, diabetic complications, and malignancies. the use of.
- the FXR receptor (farnesol X receptor) is a member of the ligand-activated transcription factor nuclear receptor family and has a typical nuclear receptor structure, ie, a highly conserved DNA binding region (DBD) at the amino terminus, and a carboxy terminal ligand binding region. (LBD), an amino terminal ligand independent transcriptional activation domain (AF1), a carboxy terminal ligand-dependent transcriptional activation domain (AF2), and an ankyl region. FXR forms a heterodimer with the retinoid X receptor (RXR).
- DBD highly conserved DNA binding region
- AF1 amino terminal ligand independent transcriptional activation domain
- AF2 carboxy terminal ligand-dependent transcriptional activation domain
- RXR retinoid X receptor
- the FXR conformation can be altered, and the binding region of the DNA binds to the FXR response element of the target gene promoter.
- a co-inhibitory factor such as NCOR
- a coactivator is recruited to exert transcriptional regulation.
- FXR is expressed in many organ tissues, including adipose tissue, liver, gastrointestinal tract, kidney, etc., and the liver is most abundantly expressed.
- FXR signaling pathway can directly or indirectly regulate the expression of multiple downstream genes, such as BSEP, SHP, CYP7A1, FGFR4, OST ⁇ / ⁇ , SREBP-1C, etc., and then regulate various metabolic pathways, such as: triglycerides, cholesterol, Blood sugar and energy stability Metabolize the metabolism of bile acids, and have the function of treating diseases such as cancer, nonalcoholic fatty liver disease, metabolic disorders, and inflammation. By inhibiting the synthesis, binding and transport of cholic acid, and regulating its metabolism, it is the main regulator of bile acid balance in the body.
- FXR agonists currently developed internationally can be divided into two major categories, one is steroids, represented by Intercept's oleic acid (OCA), for nonalcoholic fatty liver disease. Indications, in clinical phase III; the other is a novel molecular entity, an early developed compound such as GW4604 (WO2000/037077), Although it has strong agonistic activity, it is unstable to light and has low bioavailability.
- PX-104 (WO2011020615A1) developed by Phenex has been transferred to Gilead and is currently in Phase II clinical phase.
- An object of the present invention is to provide a compound having a novel molecular structure which is effective for agonizing FXR receptors, enhancing the expression levels of BSEP and SHP genes, and effectively inhibiting the expression of the CYP7A1 gene.
- FXR receptor agonists in order to achieve better therapeutic effects and better meet market demand, it is also desirable to provide FXR receptor agonists with high efficiency, low toxicity and good stability.
- the object of the present invention is to provide a novel structure of FXR receptor agonist which has excellent pharmacological effects and is a FXR receptor agonist for treating nonalcoholic fatty liver and primary biliary liver. Hardening, disorders of lipid metabolism, complications of diabetes, and malignant tumors offer possibilities.
- Another object of the present invention is to provide a method for producing the above FXR receptor agonist.
- Another object of the present invention is to provide a pharmaceutical composition and preparation containing the above FXR receptor agonist.
- a further object of the present invention is to provide a medicament for the preparation of a FXR receptor agonist for the prevention and/or treatment of nonalcoholic fatty liver disease, primary biliary cirrhosis, lipid metabolism disorder, diabetic complications and malignant tumors. Use in.
- the inventors of the present invention have conducted intensive studies to achieve the above object, and as a result, have found that a compound represented by the following formula (I), a pharmaceutically acceptable salt thereof, an ester thereof, and a stereoisomer thereof are effective for agonizing the FXR receptor, thereby completing The invention has been made.

Abstract
本发明提供下述通式(1)所示的化合物、其药学上可接受的盐、其酯或其立体异构体,本发明还提供上述化合物的制备方法以及在制备用于预防和/或治疗非酒精性脂肪肝、原发性胆汁性肝硬化、脂质代谢紊乱、糖尿病并发症及恶性肿瘤的药物中的用途。其中,R1、R2、R3、R4、m、n、W、A、Z、E、F、X、Y如说明书中所定义。
Description
本发明涉及FXR受体激动剂、其药学上可接受的盐、其酯以及它们的立体异构体,含有这些化合物的药物制剂,以及该化合物、其药学上可接受的盐、其酯以及它们的立体异构体在制备治疗和/或预防由FXR受体介导的非酒精性脂肪肝、原发性胆汁性肝硬化、脂质代谢紊乱、糖尿病并发症及恶性肿瘤等相关疾病的药物中的用途。
FXR受体(法尼醇X受体)属于配体激活转录因子核受体家族成员,具有典型的核受体结构,即氨基末端高度保守的DNA结合区(DBD)、羧基末端配体结合区(LBD)、氨基末端配体非依赖性转录激活功能区(AF1)、羧基末端配体依赖性转录激活功能区(AF2)和脚链区。FXR可与视黄醇类X受体(RXR)形成异二聚体,当配体与FXR的LBD区域结合后,FXR构象可发生改变,DNA的结合区结合到靶基因启动子的FXR反应元件(IR-1)上面,释放辅抑制因子(如NCOR),招募了辅激活因子,从而发挥转录调控作用。
FXR在多个器官组织中均有表达,包括脂肪组织、肝脏、胃肠道、肾脏等,其中肝脏中表达量最为丰富。FXR信号通路,可直接或间接调节多个下游基因的表达,如BSEP、SHP、CYP7A1、FGFR4、OSTα/β、SREBP-1C等基因,进而调节多种代谢途径,如:甘油三酯、胆固醇、血糖及能量稳定性代谢胆酸的代谢,具有治疗癌症、非酒精性脂肪肝、代谢紊乱、炎症等疾病的功能。通过抑制胆酸的合成、结合及转运,调节其代谢,是体内胆酸平衡的主要调节者。
部分天然胆酸类化合物可激动FXR受体,如鹅去氧胆酸(CDCA)、脱氧胆酸(DCA)、石胆酸(LCA)及牛磺酸和这些胆酸的甘氨酸结合物。除去天然的化合物,目前国际上研发的FXR激动剂可主要分为两大类,一类是甾体类,以Intercept公司的奥贝胆酸为代表(obeticholicacid,OCA),针对非酒精性脂肪肝适应症,处于临床III期;另一类是新型分子实体,早期研发的化合物如GW4604(WO2000/037077),
虽然具有较强的激动活性,但其对光不稳定且生物利用度较低,另外,Phenex公司研发的PX-104(WO2011020615A1)已转让给Gilead公司,目前处于临床II期研究阶段。
但是,目前依然希望能够开发出高效、低毒、且稳定性较好的新型FXR受体激动剂。
发明内容
本发明的课题在于提供具有新型分子结构的化合物,其可有效激动FXR受体,提升BSEP及SHP基因表达水平,同时有效抑制CYP7A1基因的表达。另外,为了达到更好的治疗效果的目的,更好的满足市场需求,还希望能够提供高效、低毒、且稳定性较好的FXR受体激动剂。
具体而言,本发明的目的在于提供一种新型结构的FXR受体激动剂,其具有很好的药效,为FXR受体激动剂用于治疗非酒精性脂肪肝、原发性胆汁性肝硬化、脂质代谢紊乱、糖尿病并发症及恶性肿瘤提供了可能性。
本发明的其他目的在于提供上述FXR受体激动剂的制备方法。
本发明的另一目的在于提供含有上述FXR受体激动剂的药物组合物和制剂。
本发明的再一目的在于提供上述FXR受体激动剂在制备用于预防和/或治疗非酒精性脂肪肝、原发性胆汁性肝硬化、脂质代谢紊乱、糖尿病并发症及恶性肿瘤的药物中的用途。
本发明人为了实现上述目的持续悉心研究,结果发现下述通式(I)表示的化合物、其药学上可接受的盐、其酯以及它们的立体异构体可有效激动FXR受体,从而完成了本发明。
