Synthesis, biological evaluation, and molecular modeling studies of methylene imidazole substituted biaryls as inhibitors of human 17α-hydroxylase-17,20-lyase (CYP17)—Part II: Core rigidification and influence of substituents at the methylene bridge
Thirty-five novel substituted imidazolyl methylene biphenyls have been synthesized as CYP17 inhibitors for the potential treatment of prostate cancer. Their activities have been tested with recombinant human CYP17 expressed in Escherichia coli. Promising compounds were tested for selectivity against CYP11B1, CYP11B2, and hepatic CYP enzymes 3A4, 1A2, 2B6 and 2D6. The core rigidified compounds (30-35)

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
