The molecular chaperone Hsp90 plays important roles in maintaining malignant phenotypes. Recent studies suggest that Hsp90 exerts high-affinity interactions with multiple oncoproteins, which are essential for the growth of tumor cells. As a result, research has focused on finding Hsp90 probes as potential and selective anticancer agents. In a high-throughput screening exercise, we identified quinoline
分子伴侣 Hsp90 在维持恶性表型中起重要作用。最近的研究表明,Hsp90 与多种癌蛋白产生高亲和力相互作用,这对肿瘤细胞的生长至关重要。因此,研究的重点是寻找 Hsp90 探针作为潜在和选择性的抗癌剂。在高通量筛选练习中,我们将喹啉 7 鉴定为 Hsp90 的中度抑制剂。进一步的命中识别、SAR 研究和生物学调查揭示了该系列中的几种合成类似物在荧光偏振 (FP) 测定和基于细胞的蛋白质印迹 (WB) 测定中均具有微摩尔活性。这些化合物代表了一类具有简单化学结构的新型 Hsp90 抑制剂。
