    • Structural differences in binding pockets of members of the HSP90 family can be exploited to achieve differential degradation of kinases and other signaling proteins through the use of designed small molecules which interact with the N-terminal binding pocket with an affinity which is greater than ADP and different from the ansamycin antibiotics for at least one species of the HSP90 family. Moreover, these small molecules can be designed to be soluble in aqueous media, thus providing a further advantage over the use of ansamycin antibiotics. Pharmaceutical compositions can be formulated containing a pharmaceutically acceptable carrier and a molecule that includes a binding moiety which binds to the N-terminal pocket of at least one member of the HSP90 family of proteins. Such binding moieties were found to have antiproliferative activity against tumor cells which are dependent on proteins requiring chaperones of the HSP90 family for their function. Different chemical species have different activity, however, allowing the selection of, for example Her2 degradation without degradation of Raf kinase. Thus, the binding moieties possess an inherent targeting capacity. In addition, the small molecules can be linked to targeting moieties to provide targeting of the activity to specific classes of cells. Thus, the invention further provides a method for treatment of diseases, including cancers, by administration of these compositions. Dimeric forms of the binding moieties may also be employed.
    • 可以利用HSP90家族成员的结合口袋的结构差异,通过使用与N末端结合口袋相互作用的设计的小分子来实现激酶和其他信号传导蛋白质的差异降解,其亲和力大于ADP和不同 对于至少一种HSP90家族的安莎霉素抗生素。 此外,这些小分子可以被设计成可溶于含水介质,因此比使用安莎霉素抗生素提供了进一步的优点。 药物组合物可以配制成含有药学上可接受的载体和分子,该分子包括与蛋白质的HSP90家族的至少一个成员的N-末端口袋结合的结合部分。 发现这样的结合部分具有抗肿瘤细胞的抗增殖活性,其依赖于需要HSP90家族伴侣的功能的蛋白质。 不同的化学物质具有不同的活性,然而,允许选择例如Her2降解而不降解Raf激酶。 因此,结合部分具有固有的靶向能力。 此外,小分子可以连接到靶向部分,以提供对特定细胞类别的活性的靶向。 因此,本发明还提供了通过施用这些组合物来治疗疾病,包括癌症的方法。 还可以使用结合部分的二聚体形式。
