Several 2-(arylamino)pyrimidine-5-carboxylic acids were designed as novel retinoid X receptor (RXR) antagonists. Compound 6a or 6b alone did not exhibit differentiation-inducing activity toward HL-60 cells and did not affect the activity of a retinoic acid receptor (RAR) agonist, Am80, but did inhibit the synergistic activity of an RXR agonist, PA024 (3), in the presence of Am80. The activity of 6
几种2-(芳基氨基)嘧啶-5-羧酸被设计为新型维甲酸X受体(RXR)拮抗剂。单独的化合物6a或6b并未表现出对HL-60细胞的诱导分化活性,也不影响视黄酸受体(RAR)激动剂Am80的活性,但确实抑制了RXR激动剂PA024的协同活性(3) ,在Am80的存在下。6的活性归因于RXR-RAR异二聚体的RXR位点的选择性拮抗作用。
