The present invention relates to agonists of the S1P4 receptor, which are selective for the S1P4 receptor over one or more of the S1P1, S1P2, S1P3 or S1P5 receptors of at least 10 fold, in particular new indol-alanine derivatives of structure I, process for their production, their uses, in particular in transplantation, and pharmaceutical compositions containing them
wherein
R1 is phenyl or naphthyl, wherein phenyl is substituted by one or two of halogen, C1-6alkyl, C1-6alkoxy or phenylC1-6alkyl; and
R2 is hydrogen or C1-6alkyl;
in free or salt form.
本发明涉及S1P4受体的激动剂,其在至少10倍于S1P1、S1P2、S1P3或S1P5受体上对S1P4受体具有选择性,特别是具有新的结构I的
吲哚-丙
氨酸衍
生物,其制备方法、它们的用途,特别是在移植中的用途,以及包含它们的药物组合物。其中R1是
苯基或
萘基,其中
苯基被卤素、C1-6烷基、C1-6烷
氧基或
苯基C1-6烷基中的一个或两个取代;R2是
氢或C1-6烷基;以自由形式或盐形式存在。
