Description
技术领域
本发明属于药物化学领域,具体涉及通式(I)所示的芳基磺酰胺类化合物及其生理上可接受的盐,以及这些化合物在制备尿酸盐转运蛋白1(urate transporter 1,URAT1)抑制剂中的用途,在制备预防或治疗URAT1相关疾病的药物中的应用,还涉及这些化合物的制备方法,以及含有所述化合物的药物组合物。
背景技术
痛风是尿酸单钠盐在关节及外周组织中沉积析出所导致的炎性关节疾病。尿酸生成增加或(和)排泄减少所产生的高尿酸血症是痛风的直接诱因。痛风和高尿酸血症还与代谢综合症、高血压、糖尿病、心血管疾病等多种疾病密切相关。
降尿酸疗法(urate-lowering therapy,ULT)是治疗高尿酸血症和慢性痛风的主要策略。目前降尿酸疗法主要分为三类:(1)抑制尿酸生成的黄嘌呤氧化酶(xanthineoxidase,XO)抑制剂;(2)促进尿酸排泄的尿酸盐转运蛋白1(urate transporter 1,URAT1)抑制剂;(3)使尿酸转化为水溶性物质的尿酸酶(uricase)。约90%高尿酸血症患者的发病机制与尿酸排泄减少有关,而URAT1是经临床验证调控尿酸重吸收,促进尿酸排泄的重要靶点,因此URAT1抑制剂是重要的降尿酸疗法。目前临床上应用的URAT1抑制剂主要有丙磺舒、苯溴马隆和雷西纳德。然而,丙磺舒和苯溴马隆存在耐受性差、毒副反应多等问题。2015年底上市的雷西纳德在临床上与XO抑制剂别嘌呤醇联用治疗高尿酸血症和慢性痛风,但是其对URAT1的抑制活性偏弱,临床上使用剂量大(200mg/d)。
近年来,随着人们饮食结构的改变和人口老龄化的加速,高尿酸血症和痛风发病率在持续上升,已经成为一个不可忽视的全民健康问题。目前临床治疗药物较少,而且各自存在不同的缺陷。因此,研究新型URAT1抑制剂具有重要的现实意义和市场前景。

培养稳定表达hURAT1的HEK-293T细胞株(DMEM培养基+10%胎牛血清+500μg/mLG418+1% P/S),将细胞接种到96孔细胞培养板中,培养12~24小时。化合物用DMSO配成10mM浓度的母液,再用缓冲液稀释成1mM,进一步进行4倍等比稀释。待96孔板中细胞培养贴壁后即可进行14C-尿酸在稳定表达hURAT1细胞中的吸收试验。每孔加入50微升相应化合物和0.1Ci/mL14C-尿酸溶液,在37℃培养箱中孵育5分钟后,立即加入150微升冰冷的缓冲液以终止吸收。加入50微升/孔的裂解液到所有孔中,置于振荡器上以900rpm的速度振荡5分钟;加入150微升/孔的闪烁液Microsint40,以900rpm的速度振荡5分钟;采用MicroBetaTrilux(PerkinElmer公司生产)仪器测定放射活性,并通过XL-fit软件进行分析数据。
结果:
分别测定了上述化合物在浓度为10μM时对hURAT1的抑制率;测定并计算抑制活性较好的化合物的IC50值,结果如表1所示。
