Histone deacetylase inhibitors (HDACIs) can disrupt the viability of prostate cancer (PCa) cells through modulation of the cytosolic androgen receptor (AR) chaperone protein heat shock protein 90 (HSP90). However, toxicities associated with their pleiotropic effects could contribute to the ineffectiveness of HDACIs in PCa treatment. We designed hybrid molecules containing partial chemical scaffolds
组蛋白脱乙酰基酶抑制剂(HDACIs)可通过调节胞质雄激素受体(AR)伴侣蛋白热休克蛋白90(HSP90)来破坏前列腺癌(PCa)细胞的生存能力。但是,与其多效性作用相关的毒性可能会导致HDACI在PCa治疗中无效。我们设计了杂化分子,该分子包含恩杂鲁胺和suberoylanilide异羟肟酸(SAHA)的部分化学支架,具有减弱的固有泛HDACI活性,从而靶向耐恩杂鲁胺的PCa细胞中的HSP90和AR。新分子的效力为:化合物2-75 [4-(3-(4-氰基-3-(三氟甲基)苯基)-5,5-二甲基-4-氧代-2-硫代氧杂咪唑啉-1-基)-2 -氟-N-(7-(羟基氨基)-7-氧庚基)苯甲酰胺]和1005 [(E)-3-(4-(3-(4-氰基-3-(三氟甲基)苯基)-5] [5-二甲基-4-氧代-2-硫代氧杂咪唑啉-1-基)-2-氟苯基)-N-羟基丙烯酰胺],作为核和胞质组蛋白脱乙酰基酶的抑制
