Novel compounds that have been found effective in inhibiting PDZ domain interactions, and particularly interactions of PDZ domains in MAGIs with the oncogenic (tumor suppressor) protein PTEN and interactions between the PDZ domain in the Dishevelled (Dvl) protein and other proteins such as the Frizzled (Fz) protein, have the general formula (I) or (III) The invention also includes combinatorial libraries, arrays and methods for screening and studying proteins using such compounds. Compounds of the invention have produced apoptosis in certain cell lines that overexpress the Dishevelled protein (Dvl), inhibiting Wnt signaling.
已发现的新型化合物在抑制PDZ结构域相互作用方面表现出有效性,特别是在MAGIs中的PDZ结构域与致癌(肿瘤抑制)蛋白
PTEN之间的相互作用,以及Dishevelled(Dvl)蛋白中的PDZ结构域与其他蛋白质(如Frizzled(Fz)蛋白)之间的相互作用,具有一般式(I)或(III)。该发明还包括组合式文库、阵列和使用这类化合物进行蛋白质筛选和研究的方法。该发明的化合物已在过度表达Dishevelled蛋白(Dvl)的某些
细胞系中诱导凋亡,抑制Wnt信号传导。
