  Rationally Designed High-Affinity 2-Amino-6-halopurine Heat Shock Protein 90 Inhibitors That Exhibit Potent Antitumor Activity

  摘要：

  Heat shock protein 90 (Hsp90) is a molecular chaperone protein implicated in stabilizing the conformation and maintaining the function of many cell-signaling proteins. Many oncogenic proteins are more dependent on Hsp90 in maintaining their conformation, stability, and maturation than their normal counterparts. Furthermore, recent data show that Hsp90 exists in an activated form in malignant cells but in a latent inactive form in normal tissues, suggesting that inhibitors selective for the activated form could provide a high therapeutic index. Hence, Hsp90 is emerging as an exciting new target for the treatment of cancer. We now report on a novel series of 2-amino-6-halopurine Hsp90 inhibitors exemplified by 2-amino-6-chloro-9-(4-iodo-3,5-dimethylpyridin-2-ylmethyl)purine (30). These highly potent inhibitors (IC50 of 30 = 0.009 mu M in a HER-2 degradation assay) also display excellent antiproliferative activity against various tumor cell lines (IC50 of 30 = 0.03 mu M in MCF7 cells). Moreover, this class of inhibitors shows higher affinity for the activated form of Hsp90 compared to our earlier 8-sulfanylpurine Hsp90 inhibitor series. When administered orally to mice, these compounds exhibited potent tumor growth inhibition (> 80%) in an N87 xenograft model, similar to that observed with 17-allylamino-17-desmethoxygeldanamycin (17-AAG), which is a compound currently in phase I/II clinical trials.

  日期：2019.6.2

  A new transition‐metal‐free one‐pot cascade process for the direct conversion of alcohols to nitriles was developed without introducing an “additional carbon atom”. This protocol allows transformations of readily available, inexpensive, and abundant alcohols to highly valuable nitriles.

  The process starts by reacting 2,3,5 trimethylpyridine with hydrogen peroxide in the presence of catalysts, giving new reactive ionic species allowing the number of required steps to be substantially reduced. In the final important step, oxidation to omeprazol, there are used new salts of 5-methoxy-2-((3,5-dimethyl-4-methoxy-2-pyridine)methylthio)-1H-benzimidazole which, as the oxidation evolves, precipitate the omeprazol. The new oxidation method avoids superoxidations, provide for faster oxidation, high purity and yields of over 90%.

  该过程首先是通过在催化剂存在下，将2,3,5-三甲基吡啶与过氧化氢反应，产生新的具有反应性的离子物种，从而大大减少所需步骤的数量。在最后一个重要步骤中，氧化成奥美拉唑时，使用了5-甲氧基-2-((3,5-二甲基-4-甲氧基-2-吡啶基)甲硫基)-1H-苯并咪唑的新盐，随着氧化的进行，沉淀出奥美拉唑。这种新的氧化方法避免了超氧化反应，实现了更快的氧化速度，高纯度和超过90%的产率。

  A practical, general and mild oxidation of primary and secondary alcohols to carbonyl compounds proceeds in yields of up to 99% using SO2F2 as electrophile in DMSO as both the oxidant and the solvent at ambient temperature. No moisture‐ and oxygen‐free conditions are required. Stoichiometric amount of inexpensive K2CO3, which generates easy to separate by‐products, is used as the base. Thus, 5‐gram

  在环境温度下，使用SO 2 F 2作为亲电子试剂在DMSO中作为氧化剂和溶剂，伯醇和仲醇进行实用，通用且温和的氧化成羰基化合物的收率可达99％。不需要无湿气和无氧条件。化学计量的廉价K 2 CO 3生成易于分离的副产物的油基用作基础。因此，通过简单的过滤作为后处理，以几乎定量的产量进行了5克规模的运行。还应注意使用通常促进竞争的Pummerer重排的极性溶剂（例如DMSO）。该协议与（杂）芳烃，烯烃和炔烃底物上的各种常见的N-，O-和S-官能团兼容（68个例子）。该方案被应用（99％的产率）用于重要的降胆固醇药物瑞舒伐他汀的正式合成。

  chelation‐assisted copper catalysis was employed for the development of new azides that display unprecedented reactivity in the copper(I)‐catalyzed azide–alkyne [3+2] cycloaddition (CuAAC) reaction. Azides that bear strong copper‐chelating moieties were synthesized; these functional groups allow the formation of azide copper complexes that react almost instantaneously with alkynes under diluted conditions.
