assays, the most potent agonists being di(5-fluoro-1H-indole-3-yl)methane (38, PSB-15160, EC50 80.0 nM) and di(5,7-difluoro-1H-indole-3-yl)methane (57, PSB-16671, EC50 41.3 nM). In β-arrestin assays, SARs were different, indicating biased agonism. The new compounds were selective versus related fatty acid receptors and the arylhydrocarbon receptor. Selected compounds were further investigated and found
对于g我蛋白偶联受体GPR84,它是由(羟基)脂肪酸,激活的免疫细胞上高表达。最近,3,3'-二吲哚基甲烷被鉴定为杂环类非脂质GPR84激动剂。我们在微波辐射下通过吲哚与甲醛在水中的缩合反应合成了多种二吲哚甲烷衍生物。在人GPR84上的cAMP和β-arrestin检测中对产品进行了评估。构效关系(SARs)很陡。在cAMP分析中,在吲哚环的5和/或7位带有小的亲脂性残基的3,3'-二吲哚基甲烷显示出最高的活性,最有效的激动剂是di(5-fluoro-1 H -indole-3-甲烷)(38,PSB-15160,EC 5080.0 nM)和二(5,7-二氟-1 H-吲哚-3-基)甲烷(57,PSB-16671,EC 50 41.3 nM)。在β-arrestin检测中,SAR有所不同,表明激动作用存在偏倚。新化合物对相关的脂肪酸受体和芳基烃受体具有选择性。进一步研究了选定的化合物,发现与前
