The present invention relates to screening methods useful for drug discovery of apoptosis inducing compounds. In particular, the screening methodology relates to using Apoptosis Inducing Proteins (AIPs) as a target for the discovery of apoptosis activators useful as anticancer agents. The screening methods of the present invention can employ homogenous or heterogeneous binding assays using purified or partially purified AIPs; or whole cell assays using cells with altered levels of one or more AIPs. The invention also contemplates use of gambogic acid or GA-related compounds which bind AIPs and can accordingly be used to raise antibodies useful for drug discovery. Alternatively, labeled GA is used for competitive binding assays for drug discovery. Such assays afford high throughput screening of chemical libraries for apoptosis activators.
本发明涉及用于筛选药物发现的凋亡诱导化合物的筛选方法。特别是,筛选方法涉及使用凋亡诱导蛋白(
AIPs)作为靶点,以发现作为抗癌剂有用的凋亡激活剂。本发明的筛选方法可以采用纯化或部分纯化的
AIPs的均质或非均质结合测定;或者使用具有一个或多个
AIPs
水平改变的细胞的全细胞测定。本发明还考虑使用结合
AIPs的甘波酸或GA相关化合物,可以用于制备有用于药物发现的
抗体。或者,标记的GA用于竞争性结合测定以进行药物发现。这些测定提供了
化学库的高通量筛选,以寻找凋亡激活剂。
