a strong foundation of SAR and creating a novel chemical tool for target identification of homoisoflavonoid-binding proteins, various types of photoaffinity probes were designed and synthesized in which benzophenone and biotin were attached to homoisoflavanonoids using PEG linkers on either the C-3' or C-7 position. Notably, the photoaffinity probes linking on the phenol group of the C-3' position
天然存在的异黄酮,cremastranone(1)可在体内和体外抑制血管生成。我们开发了一种类似物SH-11037(2),在人的视网膜微血管内皮细胞(HREC)中比cremastranone更有效,并能在动物模型中阻断新血管形成。尽管具有功效,但这些化合物的机理尚不完全清楚。在建立SAR的坚实基础并创建用于识别同异黄酮结合蛋白的靶标的新型化学工具的过程中,设计并合成了各种类型的光亲和探针,其中使用PEG接头在二异黄酮类化合物上将二苯甲酮和生物素连接到同异黄酮类化合物上。 C-3'或C-7位置。值得注意的是,光亲和探针连接在C-3'的酚基上
