Description
技术领域
本公开属于医药领域,涉及一种LPA1小分子拮抗剂。
背景技术
血磷脂系膜衍生生物活性脂质介体,其中医学上最重要的溶血磷脂中的一者为溶血磷脂酸(LPA),溶血磷脂影响包括增殖、分化、存活、迁移、黏附、侵袭及形态发生的基本细胞功能。这些功能影响许多生物进程,其包括但不限于神经发生、血管发生、伤口愈合、纤维化、免疫及致癌作用。
LPA是非单一分子实体而系具有不同长度及饱和度的脂肪酸的内源性结构变体的集合。LPA的结构主链是衍生自基于甘油的磷脂,诸如磷脂酰胆碱(PC)或磷脂酸(PA)。溶血磷脂酸(LPA)为已显示经特异性G-蛋白偶联受体(GPCR)组以自分泌及旁分泌方式起作用的溶血磷脂。LPA结合至其同源GPCR(LPA1、LPA2、LPA3、LPA4、LPA5、LPA6)活化细胞内信号传导途径以产生各种生物反应。发现LPA受体的拮抗剂用于治疗LPA起作用的疾病、障碍或病症。

本公开中所述化合物可药用盐可选自无机盐或有机盐。
本公开化合物可以存在特定的几何或立体异构体形式。本公开设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本公开的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本公开的范围之内。本公开的含有不对称碳原子的化合物可以以光学活性纯的形式或外消旋形式被分离出来。光学活性纯的形式可以从外消旋混合物拆分,或通过使用手性原料或手性试剂合成。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本公开某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
本发明所述化合物的化学结构中,键表示未指定构型,即如果化学结构中存在手性异构体,键可以为或或者同时包含和两种构型。本公开所述化合物的化学结构中,键并未指定构型,即键的构型可以为E型或Z型,或者同时包含E和Z两种构型。
本公开的化合物和中间体还可以以不同的互变异构体形式存在,并且所有这样的形式包含于本公开的范围内。术语“互变异构体”或“互变异构体形式”是指可经由低能垒互变的不同能量的结构异构体。例如,质子互变异构体(也称为质子转移互变异构体)包括经由质子迁移的互变,如酮-烯醇及亚胺-烯胺、内酰胺-内酰亚胺异构化。内酰胺-内酰亚胺平衡实例是在如下所示的A和B之间。
本发明中的所有化合物可以被画成A型或B型。所有的互变异构形式在本发明的范围内。化合物的命名不排除任何互变异构体。
本公开还包括一些与本文中记载的那些相同的,但一个或多个原子被原子量或质量数不同于自然中通常发现的原子量或质量数的原子置换的同位素标记的本公开化合物。可结合到本公开化合物的同位素的实例包括氢、碳、氮、氧、磷、硫、氟、碘和氯的同位素,诸如分别为2H、3H、11C、13C、14C、13N、15N、15O、17O、18O、31P、32P、35S、18F、123I、125I和36Cl等。
除另有说明,当一个位置被特别地指定为氘(D)时,该位置应理解为具有大于氘的天然丰度(其为0.015%)至少1000倍的丰度的氘(即,至少10%的氘掺入)。示例中化合物的具有大于氘的天然丰度可以是至少1000倍的丰度的氘、至少2000倍的丰度的氘、至少3000倍的丰度的氘、至少4000倍的丰度的氘、至少5000倍的丰度的氘、至少6000倍的丰度的氘或更高丰度的氘。本公开还包括各种氘化形式的式(I)化合物。与碳原子连接的各个可用的氢原子可独立地被氘原子替换。本领域技术人员能够参考相关文献合成氘化形式的式(I)化合物。在制备氘代形式的式(I)化合物时可使用市售的氘代起始物质,或它们可使用常规技术采用氘代试剂合成,氘代试剂包括但不限于氘代硼烷、三氘代硼烷四氢呋喃溶液、氘代氢化锂铝、氘代碘乙烷和氘代碘甲烷等。
“任选地”或“任选”是指意味着随后所描述的事件或环境可以但不必发生,该说明包括该事件或环境发生或不发生的场合。例如“任选的被卤素或者氰基取代的C1-6烷基”是指卤素或者氰基可以但不必须存在,该说明包括烷基被卤素或者氰基取代的情形和烷基不被卤素和氰基取代的情形。
术语解释:
