earlier, was expanded to allow the synthesis of the first series of these tetrasubstituted pyrazoles directly from alpha,beta-unsaturated ketones. The binding affinity of some of these pyrazoles for the estrogen receptor (ER) subtypes ERalpha and ERbeta is very high, and the overall affinity pattern suggests the importance of three phenol substituents for high affinity, ERalpha-selective binding.
我们已经开发了两个新颖的四取代的吡唑系列,体现了1,3-二芳基-4,5-二烷基或3,5-二芳基-1,4-二烷基取代的模式。我们先前开发的区域选择性方法的范围得以扩展,可以直接从α,β-不饱和酮合成第一系列的这些四取代的吡唑。这些吡唑中的一些对雌激素受体(ER)亚型ERalpha和ERbeta的结合亲和力非常高,总体亲和力模式表明三个酚取代基对于高亲和力,ERalpha选择性结合的重要性。
