catalyzes the aromatization reaction of androgen substrates to estrogens, the last and rate-limiting step in estrogen biosynthesis. Inhibition of aromatase is a new and promising approach to treat hormone-dependent breast cancer. We present here the design and development of isoflavanone derivatives as potential aromatase inhibitors. Structural modifications were performed on the A and B rings of isoflavanones
芳香酶 (CYP19) 催化雄激素底物对雌激素的芳香化反应,这是雌激素生物合成的最后一个限速步骤。芳香化酶的抑制是治疗激素依赖性乳腺癌的一种新的、有前景的方法。我们在此介绍了异黄烷酮衍生物作为潜在芳香酶抑制剂的设计和开发。通过微波辅助、金催化的羟基醛和炔烃的环化反应,对异黄酮的 A 和 B 环进行了结构修饰。这些化合物的体外芳香酶抑制作用是通过利用重组人芳香酶(杆状病毒/昆虫细胞表达)的基于荧光的测定来确定的。化合物 3-(4-phenoxyphenyl)chroman-4-one ( 1h ), 6-methoxy-3-phenylchroman-4-one ( 2a) 和 3-(pyridin-3-yl)chroman-4-one ( 3b ) 对芳香酶表现出有效的抑制作用,IC 50值分别为 2.4 μM、0.26 μM 和 5.8 μM。采用对接模拟来研究关键的酶/抑制剂相互作用,
