  4,5-Diarylisoxazole Hsp90 Chaperone Inhibitors: Potential Therapeutic Agents for the Treatment of Cancer

  摘要：

  Inhibitors of the Hsp90 molecular chaperone are showing considerable promise as potential chemotherapeutic agents for cancer. Here, we describe the structure-based design, synthesis, structure-activity relationships and pharmacokinetics of potent small-molecule inhibitors of Hsp90 based on the 4,5-diarylisoxazole scaffold. Analogues from this series have high affinity for Hsp90, as measured in a fluorescence polarization (FP) competitive binding assay, and are active in cancer cell lines where they inhibit proliferation and exhibit a characteristic profile of depletion of oncogenic proteins and concomitant elevation of Hsp72. Compound 40f (VER-52296/NVP-AUY922) is potent in the Hsp90 FP binding assay (IC50 = 21 nM) and inhibits proliferation of various human cancer cell lines in vitro, with GI50 averaging 9 nM. Compound 40f is retained in tumors in vivo when administered i.p., as evaluated by cassette dosing in tumor-bearing mice. In a human colon cancer xenograft model, 40f inhibits tumor growth by approximately 50%.

  针对保守的水分子：使用基于片段的筛选和基于结构的优化设计4-芳基-5-氰基吡咯并[2,3- d ]嘧啶Hsp90抑制剂

  摘要：

  Hsp90分子伴侣的抑制剂有望作为抗癌药。在这里，我们描述了一系列的4-芳基-5-氰基吡咯并[2,3- d]嘧啶ATP竞争性Hsp90抑制剂，这些是通过基于NMR的专有片段文库筛选揭示的嘌呤命中结构驱动优化后鉴定的。配体-Hsp90的X射线结构与分子建模相结合，导致了保守水分子的合理置换，从而通过荧光偏振，等温滴定量热法和表面等离振子共振测定法测量了对Hsp90的亲和力。该取代是通过腈基实现的，是有效增加结合亲和力且分子量增加最小的一个例子。该化学系列中的某些化合物在体外抑制人癌细胞系的增殖，并导致致癌的Hsp90客户蛋白耗竭并伴随伴侣伴侣Hsp70升高。此外，一种化合物被证明在小鼠中具有口服生物利用度。这项工作证明了基于结构的设计对有效的Hsp90抑制剂快速进化的强大作用，以及在药物设计中考虑保守水分子的重要性。

  Inhibitors of the Hsp90 molecular chaperone are showing considerable promise as potential molecular therapeutic agents for the treatment of cancer. Here we describe novel 2-aminothieno[2,3-d]pyrimidine ATP competitive Hsp90 inhibitors, which were designed by combining structural elements of distinct low affinity hits generated from fragment-based and in silico screening exercises in concert with structural

  Libraries of nonpurified resorcinol amide derivatives were screened by surface plasmon resonance (SPR) to determine the binding dissociation constant (off-rate, k(d)) for compounds binding to the pyruvate dehydrogenase kinase (PDHK) enzyme. Parallel off-rate measurements against HSP90 and application of structure-based drug design enabled rapid hit to lead progression in a program to identify pan-isoform ATP-competitive inhibitors of PDHK. Lead optimization identified selective sub-100-nM inhibitors of the enzyme which significantly reduced phosphorylation of the E1 alpha subunit in the PC3 cancer cell line in vitro.
