The invention relates to novel pyrrole compounds of the formula (I) wherein A represents -CH2CH2-, -CH=CH-, or -NH-CH2; Ar represents phenyl; mono-, di-, or tri-substituted phenyl, wherein the substituents are independently selected from halogen, lower alkyl, lower alkoxy, hydroxy-lower alkyl, hydroxy-lower alkoxy, 1-glyceryl, 2-glyceryl, cycloalkyl, mono- or di-lower alkylamino, methylenedioxy, ethylenedioxy, trifluoromethyl and trifluoromethoxy; or unsubstituted mono- or di-substituted 2-, 3- or 4-pyridyl, wherein the substituents are independently selected from lower alkoxy and hydroxy-lower alkoxy. The present invention provides novel compounds of formulae (I), (II) and (III) that are agonists for the G protein-coupled receptor S1P1/EDG1 and have a powerful and long-lasting immunosuppressive effect which is achieved by reducing the number of cirulating and infiltrating T- and B-lymphocytes, whitout affecting their maturation, memory or expansion. The reduction of circulating T-/B-lymphocytes as a result of S1P1/EDG1 agonism, possibly in combination with the observed improvement of endothelial cell layer function associated with S1P1/EDG1 activation, makes such compounds useful to treat uncontrolled inflammatory disease and to improve vascular functionality.
该发明涉及式(I)的新型吡咯化合物,其中A代表-CH2CH2-,-CH=CH-或-NH-CH2;Ar代表苯基;单取代、双取代或三取代苯基,其中取代基独立地选自卤素、低烷基、低烷氧基、羟基-低烷基、羟基-低烷氧基、1-甘油基、2-甘油基、环烷基、单取代或双取代的低烷基氨基、亚甲二氧基、乙二氧基、三氟甲基和三氟甲氧基;或未取代的单取代或双取代的2-、3-或4-吡啶基,其中取代基独立地选自低烷氧基和羟基-低烷氧基。本发明提供了式(I)、(II)和(III)的新型化合物,它们是G蛋白偶联受体S1P1/EDG1的激动剂,并具有强大且持久的免疫抑制作用,通过减少循环和浸润的T和B淋巴细胞的数量来实现,而不影响它们的成熟、记忆或扩张。由于S1P1/EDG1的激动作用导致循环T/B淋巴细胞的减少,可能与S1P1/EDG1激活相关的内皮细胞层功能的改善相结合,使得这类化合物在治疗不受控制的炎症性疾病和改善血管功能方面非常有用。
