Abstract
本发明公开了氘代1,2,3‑三唑LPA1抑制剂,如下式Ⅰ所示,本发明涉及氘代1,2,3‑三唑LPA1抑制剂、其药物组合物及用途
Description
技术领域
本发明属于生物医药领域,具体涉及氘代LPA1抑制剂化合物及用途。
背景技术
LPA是甘油脂质从头合成的关键代谢中间体,是质膜的组成成分。大量研究发现LPA具有生物活性,可以调节多种细胞效应,诱导多种细胞过程,包括平滑肌细胞收缩、血小板聚集、细胞增殖、细胞迁移、细胞转化、预防细胞凋亡、减少细胞因子和趋化因子分泌等。
LPA通过至少6种7次跨膜GPCRs介导的细胞外信号转导,发挥功能作用,这些LPA受体被命名为LPA1-6:蛋白质名称LPA1~LPA6,基因名称LPAR1~LPAR6(人类)和Lpar1~Lpar6(非人类)。其中,LPA1~LPA3(也分别称为vzg-1/Edg2、Edg4、Edg7)是内皮细胞分化基因家族的成员;LPA4 (P2Y9/GPR23)、LPA5 (GPR92/93)和LPA6 (P2Y5)属于嘌呤能受体(P2Y)家族。1996年,LPA1成为第一个被确认的溶血磷脂受体,是6种LPA受体中研究最为广泛的。哺乳动物LPAR1基因编码含有364个氨基酸具有7-TM结构域的相对分子质量为41 000的蛋白质。在小鼠和人类中,LPA1在心脏、脑、胎盘、骨骼肌、肾脏、胰腺、脾脏、前列腺、睾丸、卵巢、小肠和结肠中广泛表达。大量研究发现LPA/LPA1信号转导的异常可能介导一系列病理过程,如神经及精神系统疾病、疼痛、心血管疾病、纤维化、骨骼疾病、癌症、不育和肥胖等。
BMS-986278是由百时美施贵宝开发的LPA1拮抗剂,目前处于临床三期阶段,用于治疗特发性肺纤维化,另外还有一项肺纤维化间质性肺病的二期临床开发中。
氘代药物,既将药物分子的一个或多个碳氢键用碳氘键替代的新药物分子,可以通过改善原有药物的药代动力学性质,进而克服药物原有的易于代谢、副作用较大等缺陷。
本发明为氘代LPA1抑制剂药物,可以进一步改善目前LPA1抑制剂药物的药代动力学性质,降低给药剂量和可能的毒副作用。

本发明提供了一种LPA1抑制剂的氘代化合物或药学上可接受的盐,可以进一步改善LPA1抑制剂的氘代化合物或药学上可接受的盐的药代动力学性质,降低给药剂量和可能的毒副作用。
为了实现上述目的,如本发明所述一种如下式Ⅰ所示的LPA1抑制剂的氘代化合物或药学上可接受的盐:
本发明所述的LPA1抑制剂的氘代化合物或药学上可接受的盐,包括以下结构:
。
本发明所述的LPA1抑制剂的氘代化合物或药学上可接受的盐,其药学上可接受的盐选自甲磺酸盐、马来酸盐、盐酸盐或磷酸盐。
本发明所述的氘代化合物或药学上可接受的盐,包括其在制备抗肿瘤药物中的应用的应用。
本发明所述的氘代化合物或药学上可接受的盐,包括氘代化合物或药学上可接受的盐作为活性成分和药学上可接受的载体组成。
本发明所述的氘代化合物及其药学上可接受盐的药物组合物,所述药物组合物选自胶囊剂、散剂、片剂、颗粒剂、丸剂、注射剂、糖浆剂、口服液、吸入剂、软膏剂、栓剂或贴剂。
有益效果:与现有技术相比,本发明具有如下优点:
本发明提供一类氘代化合物或药学上可接受的盐,进一步改善LPA1抑制剂的药代动力学性质,降低给药剂量和可能的毒副作用。

试验例1:LPA1抑制活性测试
实验方法
将过表达hLPA1的CHO细胞或正常人肺纤维细胞的CHO细胞,每孔20000铺板,加入0.02ml的赖氨酸,孵育过夜。隔日,细胞用钙指示剂(AAT Bioquest, Sunnyvale)在室温孵育半小时,然后进行检测使用。待测化合物使用DMSO溶解,使用试验缓冲液(HBSS),20 mMHEPES和0.1%BSA进一步稀释。给药后,细胞孵育20min后,加入LPA刺激。使用logistic方程确定IC50值,根据IC50值,利用公式换算得功能亲和度数值Kb。
由此可见,表1所述实施例化合物相比于阳性对照药,均表现出优异的LPA1抑制剂活性,尤其是实施例化合物4和6活性增益尤为显著。
试验例2:化合物的药代动力学实验
(一)实验仪器和材料
高速冷冻离心机、涡旋振荡器(Vortex Genius3)、高速离心机( Eppendorf5415D)、一次性使用注射器、移液枪(Eppendorf)、实验所用SD雄性大鼠均购自扬州大学,EDTA-K2真空采血管,生理盐水。所有口服组大鼠在给药前禁食12h,自由饮水,给药期间自由进水和进食。
(二)实验步骤
实施例1或BMS-986278使用DMSO/solutol/water(10/10/80)溶解制成澄清溶液,灌胃给药化合物剂量25 mg/kg,尾静脉给药化合物的剂量为5 mg/kg。于尾静脉给药后的2min, 10 min, 30 min, 1 h, 2 h, 3 h, 5 h, 8 h, 12 h, 16 h, 24 h,从眼底静脉丛连续取血0.5 mL至肝素管中,灌胃给药后的5 min, 15 min, 30 min, 1 h, 2 h, 3 h, 5 h,8 h, 12 h, 16 h, 24 h,从眼底静脉丛连续取血0.5 mL肝素管中。将样品在8000 r,4℃条件下离心10 min后,取上层血浆0.15 mL,-20℃条件下保存,之后进行LC-MS/MS分析。数据通过WinNolin非房室模型分析,得到关键药代动力学参数。
(三)实验结果
相对于阳性药BMS-986278,实施例1、4和6口服给药的半衰期提高了一倍以上,口服生物利用度也明显提升,可以有效改进BMS-986278的给药剂量,从而降低BMS-986278高剂量给药的毒副作用。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
