A new series of coumarin inhibitors of hsp90 lacking the noviose moiety as well as substituents on C-7 and C-8 positions of the aromatic ring was synthesised and their hsp90 inhibitory activity has been delineated: for example, their capacity to induce the degradation of client proteins and to inhibit estradiol-induced transcription in human breast cancer cells. In cell proliferation assay, the most
合成了一系列新的hsp90香豆素抑制剂,它们缺少新手部分以及芳香环的C-7和C-8位置上的取代基,并且已经描述了它们的hsp90抑制活性:例如,它们诱导Hsp90降解的能力。客体蛋白并抑制雌二醇诱导的人乳腺癌细胞转录。在细胞增殖试验中,活性最高的化合物5g的效价约为其母体新霉素天然化合物的8倍。
