with hormonal adjuvant therapy in the treatment of breast cancer. Herein we report a modified synthesis of a known RARα antagonist, 2-fluoro-4-[[[8-bromo-2,2-dimethyl-4-(4-methylphenyl)chroman-6-yl]carbonyl]amino]benzoic acid and a synthesis of its unknown, desfluoro analog, 4-[[[8-bromo-2,2-dimethyl-4-(4-methylphenyl)chroman-6-yl]carbonyl]amino]benzoic acid. The modified route allows for facile reaction
视黄酸受体α(RARα) 选择性化合物可以指导可与激素辅助疗法联合用于治疗乳腺癌的药物的设计。在此,我们报告了已知 RARα 拮抗剂 2-fluoro-4-[[[[8-bromo-2,2-dimethyl-4-(4-methylphenyl)chroman-6-yl]carbonyl]amino]benzoic acid 的改进合成及其未知的脱氟类似物4-[[[8-溴-2,2-二甲基-4-(4-甲基苯基)色满-6-基]羰基]氨基]苯甲酸的合成。修改后的路线允许轻松的反应后处理,提高产量,降低成本,并纳入绿色替代步骤。通过基于功能细胞的测定确定的构效关系研究表明,这两种化合物都对 RARα 具有拮抗作用。
