Description

含不饱和脂肪烯键的噻吩并吡啶类衍生物及其制法和用途 技术领域
本发明属于医药技术领域。具体地,本发明涉及一类具有抗血小板聚集作用的化合物、其制备方法和用途以及包含所述化合物的药物组合物。更具体地,本发明涉及一种含不饱和脂肪烯键的噻吩并吡啶类衍生物、其制备方法和用途以及药物组合物。本发明还涉及所述化合物的晶型,所述晶型的制备方法和用途以及包含所述晶型的药物组合物。
背景技术
氯吡格雷是由赛诺菲和施贵宝两家制药公司联合开发并获批上市的口服ADP受体拮抗剂,它是在对早期开发的抗血小板药物噻氯吡啶进行一定结构改造的基础上研制而成,目前作为一线的抗血栓药物用于临床。但多年临床使用已证实,氯吡格雷存在很大缺陷,作为一个前体药物,氯吡格雷在体内需经过肝脏P450酶系两步代谢,代谢为活性代谢产物从而起效,而不同个体相关酶表达存在差异,尤其是第一步代谢所依赖的CYP2C19存在基因多态性,使得氯吡格雷在临床治疗效果上产生较大的个体差异,易出现“氯吡格雷抵抗”现象,会进一步造成具有一定伤害的心血管事件。
普拉格雷由日本第一三共制药与美国礼来两家公司联合开发,它是在氯吡格雷基础上,开发出的一种ADP受体拮抗剂类抗血小板药物。与氯吡格雷相比,普拉格雷起效更快、活性更强,患者对该药的反应差异较小。但普拉格雷也存在很大缺陷,其具有更大的甚至是致死性的出血风险,同时还具有如肝毒、血小板减少、中性粒细胞减少等不良反应。
同时,现有文献报道的噻吩并吡啶类化合物还存在不稳定的现象。如氯吡格雷游离碱为油状物,油状物自身存在不稳定、难以做成口服制剂等众多缺点。部分文献报道的其他噻吩并吡啶类化合物也存在类似缺点,化合物以油状物存在,需同盐酸、硫酸等强酸成盐,产品不稳定,容易降解。这些缺点导致这些化合物成药困难,或在生产、销售、存储、使用过程中容易出现问题。
迄今为止,尚没有研究证明有化合物能既解决氯吡格雷抵抗问题,又能解决普拉格雷出血副反应大、存在潜在肝毒问题,还能解决稳定性差问题。
因此,临床急需开发和研制出疗效明确、无代谢抵抗、安全性更高、稳定性更好的ADP受体拮抗剂类抗血小板药物。

本发明的式(I)结构的化合物和各化合物的晶型,在相当宽的计量范围内是有效的,例如每天服用的剂量在1~1000mg/人范围内,可以分一次或数次给药。实际服用剂量应该由医生根据有关的情况来决定,这些情况包括被治疗者的身体状态,患者的给药途径、年龄、体重、对药物的个体反应和症状的严重程度等等。
本申请的发明人惊奇地发现,药效学研究表明,本发明提供的式(I)结构的化合物具有显著的抑制血小板聚集作用,疗效优于氯吡格雷;药代研究表明,本发明式(I)结构的化合物可快速、有效地转化为药理活性代 谢物而发挥其抑制血小板聚集功效,不会因使用人群相关酶基因多态性而导致抵抗;安全性评价表明,本发明式(I)结构的化合物安全性高;药学研究表明,本发明式(I)结构的化合物易于制备,且以固体形式存在;稳定性研究表明,本发明式(I)结构的化合物稳定性好,更有利于药物的制剂、保存和使用。
同时,本申请的发明人还惊奇地发现,本发明式(I)结构的化合物以固体形式存在,而与本发明式(I)结构的化合物结构相似的化合物,不饱和脂肪烯键上仅仅一个很小的改动,如实施例化合物D-1、D-2、D-3、D-4、D-5、D-6、D-7,就会导致化合物是油状物,且难以成盐,极其不利于成药。
各项研究结果表明,本发明式(I)结构的化合物同现有技术相比,明显具有意想不到的效果。本发明式(I)结构的化合物以固体形式存在,既能解决氯吡格雷抵抗问题,又能解决部分药物出血副反应大、安全性差的问题,还能解决现有化合物稳定性差的问题,可开发成为疗效明确、无抵抗作用、稳定性更好的ADP受体拮抗剂类抗血小板药物。
本发明式(I)结构的化合物的各晶型同样具有的上述药效、药代、安全性和稳定性效果。

化合物药代特性研究:氯吡格雷属于前药,其在体内需经两步代谢才能转变为活性代谢产物,步骤如下:
Figure PCTCN2018101729-appb-000033
研究表明,人类CYP2C19存在基因多态性,主要会影响氯吡格雷第一步代谢,相当比例人群对氯吡格雷的代谢较低。据文献报道,日本人、亚洲人、澳洲人、高加索人和非裔美国人中的基因突变率分别为28%、30%、35%、13%和18%,该部分人群易产生“氯吡格雷抵抗”,从而容易发生心脑血管严重事件。故相关药物在血浆中是否可顺利代谢为2-氧代(2-Oxo)产物,可以说明该药物能否解决“药物抵抗”问题。
用人空白血浆分别制备1μM的本发明化合物、氯吡格雷硫酸氢盐(代号LBGL)、2-氧代(2-Oxo)含药血浆(双样本),37℃孵育,分别于不同时间点,取上述孵育血浆50μL,加入沉淀剂(乙腈:甲醇=7:3)100μL和内标50μL。涡旋1min,离心10min,取上清液100μL于内插管中,离心5min,进样LC-MS/MS分析。
空白对照样品制备(PPT-0),取冻存的人空白血浆100μL,加入195μL乙腈和内标100μL,再加入本发明化合物或氯吡格雷或2-氧代(20μM)5μL,涡旋1min,离心10min,取上清液100μL于内插管中,离心5min,进样LC-MS/MS分析,结果如表9–表11所示:

由试验结果可见,氯吡格雷在人血浆120min内基本稳定;本发明代表性化合物I-1、I-2在人血浆中快速生成2-氧代产物。
试验结果表明,本发明式(Ⅰ)结构的化合物不受CYP2C19基因多态性影响,在血浆中可迅速代谢为2-氧代(2-Oxo)产物,可以解决“氯吡格雷抵抗”问题。

安全性试验:
化合物I-1,I-2单次给药安全性评价:
试验设一个生理对照组、一个溶剂对照组、两个给药组,每组4只动物,雌雄各半。受试化合物分别以2g/kg剂量,经口灌胃单次给药,溶剂对照组给予相同给药体积的空白溶剂。试验期间每天观察动物各项情况;给药前、给药后1h、药后7、14天进行心电图检查;给药前、给药后1、7、12天进行血液学、血液生化检查。
给药期间及给药后观察期间动物活动正常、精神状态良好,饮食情况正常,心电图检查、血液学检查、血清生化检查均未见明显异常。
而据文献报道,普拉格雷犬急毒试验中,剂量≥300mg/kg时出现呕吐,ALP升高,血小板聚集降低等毒性表现,剂量为1000mg/kg时出现呕吐等毒性表现,剂量为2000mg/kg出现肝细胞萎缩等毒性表现。
可知灌胃给予本发明化合物对比格犬的毒性较小,动物在较大给药剂量下未见毒性反应,化合物安全性较高。
化合物I-1,I-2多次给药安全性评价:
试验设一个生理对照组、一个溶剂对照组、两个给药组,每组4只动物,雌雄各半。受试化合物设置100mg/kg、300mg/kg两个剂量组,分别经口灌胃给药14天,溶剂对照组给予相同给药体积的空白溶剂。试验期间每天观察动物各项情况;给药前、给药后第7、14天进行心电图检查;给药前、给药第7、15天进行血液学检查及血液生化检查。
100mg/kg剂量组:给药后动物活动正常、精神状态良好,饮食情况正常,给药第7、14天心电图检查、血液学检查、血清生化检查均未见明显异常。
300mg/kg剂量组:给药后动物活动正常、精神状态良好,饮食情况正常,给药第7、14天心电图检查、血液学检查、血清生化检查均未见明 显异常。
试验结果表明,连续灌胃给予本发明代表性化合物I-1和I-2 14天,对比格犬的外观、精神活动、食欲食量及血液学、血液生化及心电图等各项检查未见明显药物相关的毒性影响。未见散瞳、呕吐等异常现象,未见ALP、ALT升高等肝毒表现,未见其他异常毒性。
而据文献报道,普拉格雷在犬两周经口多次给药试验中,剂量≥100mg/kg/day时,出现散瞳、呕吐、粪便中白色物质(未吸收的受试物)、血小板聚集降低、ALP升高、肝脏总量升高、肝细胞肿胀、玻璃样表面、睾丸生精上皮萎缩等毒性反应;剂量≥300mg/kg/day时,还出现体重下降等毒性反应。
可知灌胃给予本发明式(I)结构化合物对比格犬的毒性较小,化合物安全性较高。
