The discovery and development of heat shock protein 70 (Hsp70) inhibitors is currently a hot topic in cancer. In the preceding paper in this issue (10.1021/jm401551n), we have described structure–activity relationship studies in the first Hsp70 inhibitor class rationally designed to bind to a novel allosteric pocket located in the N-terminal domain of the protein. These ligands contained an acrylamide
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。
