therapies, for example with GnRH analogues. However, steroidal drugs are known for side effects which are due to affinities for steroid receptors. Therefore we decided to synthesize non-steroidal compounds mimicking the natural CYP17 substrates pregnenolone and progesterone. The synthesis and biological evaluation of a series of 15 novel and highly active non-steroidal CYP17 inhibitors are reported. The compounds
最近,类固醇CYP17抑制剂阿比特龙进入治疗雄激素依赖性前列腺癌的II期临床试验。由于17α-羟化酶-17,20-裂合酶(CYP17)催化雄激素生物合成的最后一步,对该靶标的抑制不仅会影响睾丸,还会影响肾上腺雄激素的形成。因此,CYP17抑制剂应优于现有疗法,例如使用GnRH类似物。然而,由于类固醇受体的亲和力,类固醇药物的副作用是已知的。因此,我们决定合成模拟天然CYP17底物孕烯醇酮和孕酮的非甾体化合物。报道了一系列15种新型和高活性非甾体CYP17抑制剂的合成和生物学评估。这些化合物是通过Suzuki交叉偶联制备的,用在大肠杆菌中表达的重组人CYP17检测了格氏反应和与咪唑的CDI辅助的S N t反应及其抑制活性。进一步测试了有前途的化合物对肝酶CYP3A4和糖皮质激素形成酶CYP11B1的选择性。事实证明所有化合物均为有效的CYP17抑制剂。活性最高的化合物7和8比酮康唑具有更高的活性,其活性可与阿比特龙媲美(IC
