  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.

  copper-mediated synthesis of diaryl sulfides utilizing Cu(I)-thiophene-2-carboxylate (CuTC) is described. We demonstrate the use of CuTC as a soluble, non-basic catalyst in the coupling of aryl iodides and aryl thiols in the synthesis of synthetically advanced diaryl sulfides. This method allows for the successful coupling of challenging substrates including ortho-substituted and heteroaryl iodides and thiols

  描述了利用Cu（I）-噻吩-2-羧酸盐（CuTC）的铜介导的二芳基硫醚的合成。我们证明了在合成高级二芳基硫醚的合成中，CuTC作为可溶性，非碱性催化剂在芳基碘化物和芳基硫醇的偶联中的应用。这种方法可以成功地耦合包括邻位在内的具有挑战性的基材-取代的和杂芳基碘化物和硫醇。另外，这里使用的大多数芳基碘化物底物包含与嘧啶，吡啶或苯环键合的特权哌嗪支架，因此该方法允许将复杂的哌嗪支架加工成具有生物学意义的分子。此处描述的方法可以将后期结构的多样性纳入到含有哌嗪环的二芳基硫醚中，从而提高了可用于SAR研究的衍生物的数量和性质。
