  Analogues of the Allosteric Heat Shock Protein 70 (Hsp70) Inhibitor, MKT-077, As Anti-Cancer Agents

  摘要：

  The rhodacyanine, MKT-077, has antiproliferative activity against cancer cell lines through its ability to inhibit members of the heat shock protein 70 (Hsp70) family of molecular chaperones. However, MKT-077 is rapidly metabolized, which limits its use as either a chemical probe or potential therapeutic. We report the synthesis and characterization of MKT-077 analogues designed for greater stability. The most potent molecules, such as 30 (JG-98), were at least 3-fold more active than MKT-077 against the breast cancer cell lines MDA-MB-231 and MCF-7 (EC50 values of 0.4 +/- 0.03 and 0.7 +/- 0.2 mu M, respectively). The analogues modestly destabilized the chaperone clients, Aka and Raf1, and induced apoptosis in these cells. Further, the microsomal half-life of JG-98 was improved at least 7-fold (t(1/2) = 37 min) compared to MKT-077 (t(1/2) < 5 min). Finally, NMR titration experiments suggested that these analogues bind an allosteric site that is known to accommodate MKT-077. These studies advance MKT-077 analogues as chemical probes for studying Hsp70s roles in cancer.

  The molecular chaperone, Heat Shock Protein 70 (Hsp70), is an emerging drug target for neurodegenerative diseases, because of its ability to promote degradation of microtubule-associated protein tau (MAPT/tau). Recently, we reported YM-08 as a brain penetrant, allosteric Hsp70 inhibitor, which reduces tau levels. However, the benzothiazole moiety of YM-08 is vulnerable to metabolism by CYP3A4, limiting

  分子伴侣热休克蛋白 70 (Hsp70) 是一种新兴的神经退行性疾病药物靶点，因为它能够促进微管相关蛋白 tau (MAPT/tau) 的降解。最近，我们报道了 YM-08 作为脑渗透剂、变构 Hsp70 抑制剂，可降低 tau 水平。然而，YM-08 的苯并噻唑部分易受 CYP3A4 代谢的影响，限制了其作为化学探针的进一步应用。在这篇手稿中，我们通过将卤素原子系统地引入苯并噻唑环并改变末端吡啶中杂原子的位置，设计并合成了 17 种 YM-08 衍生物。在微粒体测定中，我们发现化合物 JG-23 的代谢稳定性提高了 12 倍，并且在两种基于细胞的模型中保留了降低 tau 水平的能力。
