New methods for the preparation of multi-functionalized-6,11-dihydrodibenz[b,e]oxepins were developed. The structural requirements of KW-4994 (1), a promising orally active antiallergic agent, were defined. A carboxyl group at C-2 was critical for enhanced antiallergic activity of 1. The introduction of bromine atom at C-9 of 1 could elongate the duration of the action of the parent. Antiplatelet activity
开发了制备多功能的6,11-二氢二苯并[b,e]氧杂环丁烷的新方法。确定了有希望的口服活性抗过敏药KW-4994(1)的结构要求。C-2处的羧基对于增强1的抗过敏活性至关重要。在C-9处引入1的溴原子可以延长亲本的作用时间。在1的衍生物之一中观察到抗血小板活性,这是该系列化合物的新药理特性。
