  摘要：

  盖尔达霉素衍生物可以在飞托摩尔浓度下阻断uPA-纤溶酶网络，抑制胶质母细胞瘤细胞和其他肿瘤的生长和侵袭，潜在地是高活性的抗癌药物。已披露了盖尔达霉素（GA）和各种17-氨基-17-去甲氧基盖尔达霉素衍生物，可以在飞托摩尔水平下阻断HGF/SF介导的Met酪氨酸激酶受体依赖的uPA激活。其他吖丝霉素类化合物（马克贝辛I和II）、盖尔达霉素衍生物和雷地可（radicicol）需要更高几个数量级（≥nM）的浓度才能实现这种抑制作用。经测试的化合物的抑制活性与该类药物已知结合到hsp90的能力不符，表明存在一种新的靶标，用于抑制HGF/SF介导的肿瘤发展事件。公开了使用这类化合物来抑制癌细胞活动和治疗肿瘤的方法。用这些高活性化合物的低剂量进行治疗为治疗各种表达Met的肿瘤提供了一种选择，特别是侵袭性脑癌，可以单独使用或与常规手术、化疗或放疗结合使用。

  Geldanamycin interferes with the action of heat shock protein 90 (Hsp90) by binding to the N-terminal ATP binding site and inhibiting an essential ATPase activity. In a program directed toward finding potent, water soluble inhibitors of Hsp90, we prepared a library of over sixty 17-alkylamino-17-demethoxygeldanamycin analogs, and compared their affinity for Hsp90, ability to inhibit growth of SKBr3 mammalian cells, and in selected cases, water solubility. Over 20 analogs showed cell growth inhibition potencies similar to that of 17-allylamino-17-demethoxygeldanamycin (17-AAG), the front-runner geldanamycin analog that is currently in multiple clinical trials. Many of these analogs showed water solubility properties that were desirable for formulation. One of the most potent and water-soluble analogs in the series was 17-(2-dimethylaminoethyl)amino-17-demethoxygeldanamycin (17-DMAG), which was independently prepared by the NCI and will soon enter clinical trials. Importantly, the binding affinity of these analogs to the molecular target Hsp90 does not correlate well with their cytotoxicity in SKBr3 cells. (C) 2004 Elsevier Ltd. All rights reserved.

  The erbB-2 oncogene encodes a transmembrane protein tyrosine kinase which plays a pivotal role in signal transduction and has been implicated when overexpressed in breast, ovarian, and gastric cancers. Naturally occurring benzoquinoid ansamycin antibiotics herbimycin A, geldanamycin (GDM), and dihydrogeldanamycin were found to potently deplete p185, the erbB-2 oncoprotein, in human breast cancer SKBR-3 cells in culture. Chemistry efforts to modify selectively the quinoid moiety of GDM afforded derivatives with greater potency in vitro and in vivo. Analogs demonstrated inhibition of p185 phosphotyrosine in cell culture and in vivo after systemic drug administration to nu/nu nude mice bearing Fisher rat embryo cells transfected with human erbB-2 (FRE/erbB-2). Specifically, dosed intraperitoneally at 100 mg/kg, 17-(allylamino)-17-demethoxygeldanamycin and other 17-amino analogs were effective at reducing p185 phosphotyrosine in subcutaneous flank FRE/erbB-2 tumors. Modifications to the 17-19-positions of the quinone ring revealed a broad structure-activity relationship in vitro.

  The invention features methods, compositions, and kits for the administration of an HSP90 inhibitor, OBAA, flunarizine, aphidicolin, damnacanthal, dantrolene, or an analog thereof, alone, or in combination with, e.g., a TAA, an antigen-binding scaffold (e.g., an antibody, a soluble T cell receptor, or a chimeric receptor) specific for a TAA, a cell (e.g., a white blood cell that targets a cancer cell), and/or an IFN-β receptor agonist or an IFN-γ receptor agonist, for the treatment of cancer.
