for treatment of metastatic castration-resistant prostate cancer (mCRPC), approximately 20–40% of patients have no response to these agents. It has been stipulated that the lack of response and the development of secondary resistance to these drugs may be due to the presence of AR splice variants. HDAC6 has a role in regulating the androgen receptor (AR) by modulating heat shock protein 90 (Hsp90)
尽管恩杂鲁胺和阿比特龙被批准用于治疗转移性去势抵抗性前列腺癌(mCRPC),但大约20–40%的患者对这些药物无反应。已经规定对这些药物缺乏应答和继发性耐药的发展可能是由于AR剪接变体的存在。HDAC6通过调节热休克蛋白90(Hsp90)乙酰化来调节雄激素受体(AR)的作用,该过程可控制雄激素依赖性和独立情况下AR的核定位和激活。使用双作用AR–HDAC6抑制剂,应该有可能靶向对恩杂鲁胺无反应的患者。在本文中,我们描述了靶向AR且对HDAC6特异的双作用化合物的设计,合成和生物学评估。10,其被发现具有强效的双重活性(IC HDAC6 50 = 0.0356μM和AR结合IC 50 = <0.03μM)。进一步评价化合物10的拮抗剂和其他基于细胞的活性,体外稳定性和药代动力学。
