Trp741→Cys that cause anti-androgens such as flutamide and bicalutamide to function as agonists are likely associated with anti-androgen withdrawal syndrome in PCa therapy. The recently solved crystal structure of bicalutamide was used to design analogues that would complement the Trp741→Leu mutation, effectively restoring antagonist action of the ligand. Three out of the six designed analogues showed potent
核/类固醇激素受体 (NHR) 作为参与发育和体内平衡的不同基因组的配体依赖性转录调节因子发挥作用。NHR 成员雄激素受体 (AR) 的突变与激素疗法在前列腺癌 (PCa) 治疗中的失败有关。已经提出AR突变如Thr877→Ala、Trp741→Leu和Trp741→Cys导致抗雄激素如氟他胺和比卡鲁胺作为激动剂起作用,可能与PCa治疗中的抗雄激素戒断综合征有关。最近解决的比卡鲁胺晶体结构用于设计类似物,以补充 Trp741→Leu 突变,有效恢复配体的拮抗作用。
