2.49%. To improve the chemical efficacy and bioavailability, we designed and synthesized NOR analogues. Using various in vitro assays, 2-methoxy-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinoline-9-ol (III11) was discovered as a potent AhR agonist. Compound III11 enhanced the expression of AhR downstream target genes, triggered AhR nuclear translocation, and promoted differentiation of regulatory T cells
芳烃受体(AhR)是一种转录因子,属于基本螺旋-环-螺旋-Per-ARNT-SIM家族,与健康和疾病密切相关。以 AhR 为靶点是针对多种疾病的新兴治疗策略。Norisoboldine (NOR) 是乌药的主要生物碱,已知可以激活 AhR。不幸的是,NOR的口服生物利用度(F)仅为2.49%。为了提高化学功效和生物利用度,我们设计并合成了NOR类似物。使用各种体外测定,发现2-甲氧基-5,6,6a,7-四氢-4H-二苯并[de,g]喹啉-9-醇( III 11 )是一种有效的AhR激动剂。化合物III 11增强AhR下游靶基因的表达,触发AhR核转位,促进调节性T细胞分化。更重要的是,III 11在10 mg/kg的剂量下在溃疡性结肠炎小鼠模型中表现出良好的生物利用度(F = 87.40%)和显着的治疗效果。这些发现可为设计新型抗免疫和炎症疾病的AhR激动剂提供参考。
