孤儿受体GPR17可能是炎性疾病的新型药物靶标。3-(2-羧乙基)-4,6-二氯-1- ħ -吲哚-2-羧酸(MDL29,951,1)先前被确定为有效的适度GPR17激动剂。在本研究中,我们调查的结构-活性关系(SARS)1。取代吲哚的1-,5-或7-位是有害的。在4-位仅容忍小的取代基,而在6-位容纳大的亲脂性残基。最有效的化合物是含有以下取代基的3-(2-羧乙基)-1 H-吲哚-2-羧酸衍生物:6-苯氧基(26,PSB-1737,EC 50 270 nM),4-氟-6 -溴(33,PSB-18422,EC 50 27.9 nM),4-氟-6碘(35,PSB-18484,EC 50 32.1 nM)和4-氯-6己氧基(43,PSB-1767,EC 50 67.0 nM)。(3-(2-羧乙基)-6-己氧基-1 H-吲哚-2-羧酸(39,PSB-17183,EC 50 115 nM)表现为部
