Description

(1R,3S)-1-(4-羟基-3-甲氧羰基)-1,2,3,4-四氢-β-咔啉-3-甲酰氨基酸衍生物及其制备和应用
技术领域
本发明涉及一种抗血小板药物,特别涉及(1R,3S)-1-(4-羟基-3-甲氧羰基)-1,2,3,4-四氢-β-咔啉-3-甲酰氨基酸衍生物及其制备和应用,属于生物医药领域。
背景技术
血栓性疾病是严重危害人类健康的重大疾病之一。血栓形成一般认为与多种因素引起的血小板聚集、黏附及释放有关。因此,抗血小板药一直是人们研究的热点。
S-咔啉羧酸是从小根蒜或薤中分离得到的一种生物碱,具有安全、便宜等优点,而且具有明确的抗血小板聚集活性,咔啉羧酸的体外实验证明其抗血小板聚集活性是阿司匹林的6倍。实验室以前的研究成果表明,将内源性的氨基酸引入咔啉羧酸的3位羧基,能明显改善其水溶性,提高生物利用度,增强抗血小板聚集活性。发明人在研究中认识到,3-位氨基酸修饰的咔啉羧酸的抗栓活性与它们的构象伸展程度(Jiawang Liu,Xueyun Jiang,Ming Zhao,Xiaoyi Zhang,Meiqing Zheng,Li Peng and Shiqi Peng,A class of 3S-2-aminoacyltetrahydro-β-carboline-3-carboxylic acids:Their facile synthesis,inhibition for plateletactivation and high in vivo anti-thrombotic potency.J.Med.Chem.2010,53,3106-3116)。发明人计算了一批1-位不同取代基取代的3-位氨基酸修饰的咔啉羧酸,发现1-位水杨酸甲脂取代的3-位氨基酸修饰的咔啉羧酸的构象伸展程度最高。基于这些理由,本发明以1-位水杨酸甲脂取代的咔啉羧酸为母核,将内源性氨基酸对咔啉羧酸母核的3-位羧基进行修饰,得到新型的咔啉羧酸衍生物并对其进行体内外抗血栓评价,期望可以改善药物的转运与代谢过程,提高生物利用度,获得更好的抗血栓活性。

表1为母核3及化合物5a-p对PAF和TH诱导的血小板聚集作用的影响。
表2为母核3及化合物5a-p对ADP诱导的血小板聚集作用的影响。
表1数据说明除母核3外,16个氨基酸修饰的目标化合物对PAF(血小板活化因子,终浓度1×10-6M)诱导的血小板聚集有抑制作用,母核3以及16个氨基酸修饰的目标化合物对TH(凝血酶,终浓度1×10-5M)诱导的血小板聚集具有明显抑制作用。
表2数据说明母核3以及16个氨基酸修饰的目标化合物对ADP(二磷酸腺苷,终浓度1×10-6M)诱导的血小板聚集基本无抑制作用。
通过数据还可以看到本发明经过氨基酸修饰后的目标化合物抑制PAF以及TH诱导的血小板聚集作用比母核抑制作用明显增强。
