  摘要：

  热休克蛋白70（Hsp70）抑制剂的发现和开发是目前癌症领域的热门话题。在本期的前一篇论文 (10.1021/jm401551n) 中，我们描述了第一个 Hsp70 抑制剂类的结构-活性关系研究，这些抑制剂经过合理设计以结合位于蛋白质 N 端结构域的新型变构口袋。这些配体含有丙烯酰胺，以利用嵌入变构口袋中的活性半胱氨酸，并在结合时充当共价蛋白质修饰剂。在这里，我们围绕不可逆抑制剂支架进行化学修饰，以证明共价修饰不是此类化合物活性的必要条件。该研究确定了衍生物27c，它模拟了不可逆抑制剂在可比浓度下的生物效应。总的来说，背靠背手稿描述了第一个药效团，这些药效团与 Hsp70 中从未探索过的口袋有利地和选择性地相互作用，并为 Hsp70 定向配体的癌症导向开发提供了新的蓝图。

  Heat Shock Protein 70 Inhibitors. 1. 2,5′-Thiodipyrimidine and 5-(Phenylthio)pyrimidine Acrylamides as Irreversible Binders to an Allosteric Site on Heat Shock Protein 70

  摘要：

  Heat shock protein 70 (Hsp70) is an important emerging. cancer. target whose inhibition may affect multiple cancer-associated signaling pathways and, moreover, result in significant cancer cell apoptosis. Despite considerable interest from both academia and pharmaceutical companies in the discovery and development of druglike Hsp70 inhibitors, little success has been reported so far. Here we describe structure activity relationship studies in the first rationally designed Hsp70 inhibitor class that binds to a novel allosteric pocket located in the N-terminal domain of the protein. These 2,5'-thiodipyrimidine and 5-(phenylthio)-pyrimidine acrylamides take advantage of an active cysteine embedded in the allosteric pocket to act as covalent protein modifiers upon binding. The study identifies derivatives 17a and 20a, which selectively bind to Hsp70 in cancer cells. Addition of high nanomolar to low micromolar concentrations of these inhibitors to cancer cells leads to a reduction in the steady-state levels of Hsp70-sheltered oncoproteins, an effect associated with inhibition of cancer cell growth and apoptosis. In summary, the described scaffolds represent a viable starting point for the development of druglike Hsp70 inhibitors as novel anticancer therapeutics.
