  Geldanamycin derivatives and neuroprotective effect on cultured P19-derived neurons

  摘要：

  Geldanamycin (1), an antifungal and anticancer ansamycin, was reported as a neurotrophic and neuroprotective substance against antineoplastic drugs, pactitaxel, vincristine, and cisplatin, on cultured dorsal root ganglion neurons from chick embryos. In this study, 1 in a large quantity, together with a known 17-O-demethylgeldanamycin (2), and a new 17-O-demethylgeldanamycin hydroquinone (3) were obtained from a mangrove Streptomyces sp. A series of O-alkyl and N-alkyl derivatives of 1 were prepared by modification of C-17 and/or C-19 on the quinone ring and were evaluated for in vitro activity against P19-derived neurons. Compound 1 and 19-O-methylgeldanamycin (7) at a very low dose (1 nM) enhanced survival and neurite outgrowth of P19-derived neurons and prevented neurotoxicity of paclitaxel and vinblastine. Compound 7, possessing the lowest cytotoxicity and neurotoxicity, is serving as the most promising candidate in neurodegenerative therapy against neurotoxic anticancer drugs. (c) 2006 Elsevier Ltd.

  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 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.

  The present invention provides pharmacological compounds including an effector moiety conjugated to a binding moiety that directs the effector moiety to a biological target of interest. Likewise, the present invention provides compositions, kits, and methods (e.g., therapeutic, diagnostic, and imaging) including the compounds. The compounds can be described as a protein interacting binding moiety-drug conjugate (SDC-TRAP) compounds, which include a protein interacting binding moiety and an effector moiety. For example, in certain embodiments directed to treating cancer, the SDC-TRAP can include an Hsp90 inhibitor conjugated to a cytotoxic agent as the effector moiety.
