  Fragment-Based Drug Discovery Applied to Hsp90. Discovery of Two Lead Series with High Ligand Efficiency

  摘要：

  Inhibitors of the chaperone Hsp90 are potentially useful as chemotherapeutic agents in cancer. This paper describes an application of fragment screening to Hsp90 using a combination of NMR and high throughput X-ray crystallography. The screening identified an aminopyrimidine with affinity in the high micromolar range and subsequent structure-based design allowed its optimization into a low nanomolar series with good ligand efficiency. A phenolic chemotype was also identified in fragment screening and was found to bind with affinity close to 1 mM. This fragment was optimized using structure based design into a resorcinol lead which has subnanomolar affinity for Hsp90, excellent cell potency, and good ligand efficiency. This fragment to lead campaign improved affinity for Hsp90 by over 1,000,000-fold with the addition of only six heavy atoms. The companion paper (DOI: 10.1021/jm100060b) describes how the resorcinol lead was optimized into a compound that is now in clinical trials for the treatment of cancer.

  The cumulative evidence supports STAT3, a transcriptional mediator of oncogenic signaling, as a therapeutic target in cancer. The development of STAT3 inhibitors remain an active area of research as no inhibitors have yet to be approved for cancer treatment. In a continuing effort to develop more potent STAT3 inhibitors based on our previously identified hit compound 16w, a series of benzothiazole

  累积的证据支持STAT3（一种致癌信号的转录介质）作为癌症的治疗靶标。STAT3抑制剂的开发仍然是一个活跃的研究领域，因为尚未批准任何抑制剂用于癌症治疗。在基于我们先前确定的命中化合物16w不断开发更有效的STAT3抑制剂的过程中，设计，合成和生物学评估了一系列在STAT3的SH2结构域具有独特结合模式的苯并噻唑衍生物。值得注意的是，化合物B19对IC 50表现出优异的针对IL-6 / STAT3信号通路的活性通过萤光素酶报告基因测定法测定的值低至0.067μM。此外，多种化合物显示出对MDA-MB-468和JAK2突变HEL细胞系有效的抗增殖活性。使用蛋白质印迹法的进一步生化研究表明，B19阻断了Tyr 705和Ser 727处STAT3的磷酸化，从而抑制了STAT3介导的c-MYC和MCL-1基因表达。同时，它在MDA-MB-468和HEL细胞系中诱导癌细胞G2 / M期阻滞和凋亡。最
