Description

FXR小分子激动剂及其制备方法和用途 技术领域
本发明涉及医药领域，涉及一类作为FXR激动剂的化合物及其制备和用途。具体而言，涉及一类可作为FXR激动剂的非甾体化合物及其对映异构体、非对映异构体、互变异构体、溶剂合物、前药、或其药学上可接受的盐，其制备方法以及其在制备治疗FXR相关疾病药物中的应用。
背景技术
核受体广泛存在生物体内，是一类依靠特异性配体激活的核转录调节因子，代谢性核受体是核受体中的一类，在体内调控者物质代谢、细胞增殖、凋亡等。法尼醇X受体(farnesoid X receptor,FXR)是核受体超家族的一员，最早于1995年由Foman等首次发现，因其转录活性可被法尼酯增强而命名。
FXR结构包含氨基端非配体依赖性的转录活化域(AF1)，DNA结合域(DBD)，铰链区，配体结合域(LBD)以及碳端配体依赖的转录活化域(AF2)，是典型的核受体结构。FXR在体内由胆汁酸激活，参与生命体中胆汁酸代谢、脂代谢、糖代谢等过程。FXR调控胆汁酸代谢和转运机制主要通过调控胆汁酸合成限速酶胆固醇7α羟化酶(cholesterol 7α-hydroxylase，CYP7A1)的转录完成，尽管FXR不能直接作用于CYP7A1启动子上，但是可诱导小分子异源二聚体伴侣(small heterodimer partner，SHP)的表达并结合HNF-4α(hepatocyte nuclear factor 4α，)以及LRH-1(liver receptor homolog)来下调CYP7A1的转录。脂代谢过程中，肝脏中FXR通过直接或间接调控PPARα，VLDL受体(very low density lipoprotein receptor，VLDLR)、前蛋白转化酶枯草溶菌素-9(proprotein convertase subtilisin kexin type 9，PCSK9)、肝脏清道夫受体(scavenger receptor group B type 1，SRB1)、磷脂转运蛋白(phosphor lipid transfer protein，PLTP)、肝脏X受体(liver X receptor，LXR)、固醇调节元件结合蛋白-1C(sterol regulatory element-binding protein-1C，SREBP-1C)和脂肪酸合成酶(fatty acid synthetase，FAS)、活化脂蛋白脂酶(lipoprotein lipase，LPL)等，调控脂质代谢和转运而达到降低血浆游离脂肪酸以及甘油三酯。在糖代谢过程中，FXR的激活能够促进肝脏糖原的合成以及增加胰岛素的敏感性及胰岛素分泌来控制体内血糖水平。由于FXR在胆汁酸代谢、脂代谢和糖代谢等过程中都起着重要的作用，FXR配体小分子化合物有望成为治疗高甘油三酯血症、2型糖尿病、代谢综合征以及NAFLD等代谢相关疾病治疗的新药。

体内肝纤维化药理活性测试
1)化合物1(LXF-32)对TAA诱导的肝纤维化模型大鼠的药效学评价
本实验采用TAA诱导肝纤维化模型大鼠，考察化合物1长期口服给药对该模型大鼠肝纤维化的影响。
实验方法：雄性SD大鼠按150mg/kg剂量一周三次腹腔注射硫代乙酰胺(TAA，溶于生理盐水)诱导肝纤维化模型。造模四周后，对大鼠进行眼球后静脉丛取血，检测血清ALP指标，根据ALP、体重等指标，将大鼠随机分为3组，每组8只，分别为模型对照组(Vehicle)、化合物1组(20mg/kg)、阳性化合物OCA组(20mg/kg)等，口服灌胃给药，一天一次。给药期间监测动物摄食和体重，给药2周后对大鼠进行眼球后静脉丛取血，检测血清ALP指标，给药4周眼球后静脉丛取血后脱臼处死大鼠，取肝脏称量肝重后取部分肝脏用4％多聚甲醛固定，部分肝脏-80℃冻存。整个实验过程中另设8只同窝大鼠腹腔注射相同体积的生理盐水作为系统正常对照组(WT)。该实验通过检测血清中肝功能指标ALP水平、肝脏中α-SMA及Col1α1(纤维化相关基因)基因水平的表达、肝脏中羟脯氨酸(胶原特征性氨基酸)含量及肝脏病理学改变(天狼猩红染色)等指标反映化合物是否具有缓解肝纤维化的作用。
研究结果表明，本发明的化合物1给药4周能够显著降低血清中ALP水平、降低肝脏组织中羟脯氨酸的含量、显著下调肝脏组织中α-SMA及Col1α1 mRNA表达(图1)；对天狼猩红染色的肝脏病理切片的定量分析中，化合物1能减少肝脏中胶原含量，因模型组组内差异大，无统计学差异(图2)。
综上所述，本发明的化合物1(LXF-32)长期给药能明显改善TAA诱导肝纤维化大鼠的肝功能，下调α-SMA及Col1α1 mRNA表达，减少肝脏中胶原的沉积，对肝纤维化有一定的缓解作用。
2)化合物8(LXF-116)对CCL4诱导的肝纤维化模型小鼠的药效学评价
本实验采用CCl4诱导肝纤维化模型小鼠，考察化合物化合物8长期口服给药对该模型小鼠肝纤维化的影响。
实验方法：雄性C57BL/6j小鼠按2mL/kg、10％CCl4(溶于橄榄油)一周三次腹腔注射诱导肝纤维化模型。造模两周后，对小鼠进行眼球后静脉丛取血，检测血清ALT、AST、TBA、LDH指标，根据ALT、AST、TBA、LDH、体重等指标，将小鼠随机分为5组，每组10只，分别为模型对照组(Vehicle)、化合物8低剂量组(6mg/kg)，化合物8高剂量组(20mg/kg)、阳性化合物OCA低剂量组(6mg/kg)，OCA高剂量组(20mg/kg)等，口服灌胃给药，一天一次。给药期间监测动物摄食和体重，给药3周后对小鼠进行眼球后静脉丛取血，检测血清ALT、AST、TBA、LDH、指标，给药6周眼球后静脉丛取血后脱臼处死小鼠，取肝脏称量肝重后取部分肝脏用4％多聚甲醛固定，部分肝脏-80℃冻存。整个实验过程中另设10只同窝小鼠腹腔注射相同体积的橄榄油作为系统正常对照组(WT)。该实验通过检测血清中肝功能指标ALT、AST、TBA、LDH水平、肝脏中α-SMA及Col1α1基因水平的表达及肝脏病理学改变(天狼猩红染色)等指标反映化合物是否具有缓解肝纤维化的作用。
研究结果表明，本发明的化合物8高低剂量组给药6周均能显著降低血清中ALT、AST、TBA的水平，对LDH影响不大；阳性化合物OCA高剂量组能显著降低血清中ALT、AST、TBA的水平，低剂量组仅对TBA有降低作用；化合物8低剂量的效果略优于OCA的低剂量组(图3)。化合物8高剂量组能显著下调肝脏中α-SMA表达，下调肝脏中col1α1表达(图4)；对天狼猩红染色的肝脏病理切片的定量分析中，化合物8高低剂量组均能显著减少肝脏中胶原含量，化合物8低剂量的效果略优于OCA的低剂量组(图5)。
综上所述，本发明的化合物8(LXF-116)长期给药能明显改善CCl4诱导肝纤维化小鼠的肝功能，下调α-SMA及Col1α1 mRNA表达，减少肝脏中胶原的沉积，对肝纤维化有较好的缓解作用。
