antibiotics are not only potent inhibitors of DNA gyrase but also represent the most effective C-terminal inhibitors of 90 kDa heat shock proteins (Hsp90) reported thus far. In contrast to the N-terminal ATP-binding site, little is known about the Hsp90 C-terminus. In addition, very limited structure-activity relationships exist between this class of natural products and Hsp90. In this letter, the syntheses
香豆素抗生素不仅是DNA促旋酶的有效抑制剂,而且是迄今为止报道的最有效的90 kDa热休克蛋白(Hsp90)C端抑制剂。与N端ATP结合位点相反,对Hsp90 C端的了解很少。此外,这类天然产物与Hsp90之间存在非常有限的构效关系。在这封信中,介绍了二聚香豆素类似物的合成及其在乳腺癌细胞系中的抑制作用。
