[Structure: see text] The total synthesis and preliminary biological evaluation of the first bryostatin analogs (bryologs) to incorporate B-ring substitution are reported. Asymmetric syntheses of two new polyketide "spacer" domains are described, one exploiting the pseudosymmetry of the C1-C13 region. These fragments are convergently joined to the "recognition" domain through a remarkably versatile
[结构:见正文]报告了第一个纳入B环取代的bryostatin类似物(bryologs)的总合成和初步生物学评估。描述了两个新的聚酮化合物“间隔”域的不对称合成,其中一个利用了C1-C13区域的拟对称性。这些片段通过非常通用的宏缩醛化过程会聚到“识别”域。所得的新类似物对蛋白激酶C(PKC)表现出强大的纳摩尔或皮摩尔亲和力,与溴代他汀相似或更好。
