  The new analogue 2 of combretastatin A-4 was discovered to be an inhibitor of tubulin polymerization with an IC50 of 7.6 microM and reduced angiogenesis in the in vivo chick embryo model. Interestingly, in a series of 2,3-diarylmaleimides closely related to this lead, no other compound was found to be active in the tubulin polymerization assay. However, by screening in the in vivo chick embryo assay

  发现康美他汀A-4的新类似物2是微管蛋白聚合的抑制剂，在体内鸡胚模型中的IC50为7.6 microM，并减少了血管生成。有趣的是，在一系列与该铅紧密相关的2，3-二芳基马来酰亚胺中，在微管蛋白聚合测定中未发现其他化合物具有活性。然而，通过在体内进行筛选，将雏鸡胚胎测定法10鉴定为有效的血管生成抑制剂，表明了另一种靶标。确实，分子建模研究表明在模型激酶CDK2的ATP结合位点有一个合理的10结合模式。根据这些结果，在10种类似的12种蛋白激酶中筛选了10种类似物的抑制活性，发现10种对VEGF-R2的高亲和力表明IC50为2.5 nM。

  A facile preparation of trans-epoxides was achieved by a (EtO)3P–ZnBr2-mediated deoxygenation reaction of the corresponding 2-nitrobenzaldehydes. The sterically hindered analogues of 2-nitrobenzaldehyde underwent a reaction with triethyl phosphite in the presence of ZnBr2 as the catalyst to form benzisoxazoles as the sole product. Under identical conditions, the reactions of electron-rich as well as
