  摘要：

  核糖核苷酸还原酶（RR）是已确立的癌症靶标，通常被抗代谢物抑制，该抗代谢物表现出多种交叉反应作用。最近，我们发现了基于萘基水杨酰基的人RR（hRR）的抑制剂（NSAH或E - 3a）在催化位点（C-位）结合并可逆地抑制hRR。我们在此报告了25种不同类似物的合成和生化特性。我们基于2.7ÅX射线晶体结构（PDB ID：5TUS），通过对接至hRR的C位点设计了每个类似物。观察到对微小结构变化的广泛耐受性，从而保持了抑制效力。E - 3f（82％的收率）显示了体外IC 50相对于hRR为5.3±1.8μM，使其在该系列中最有效。动力学测定表明，E - 3a，E - 3c，E - 3t和E - 3w通过可逆和竞争模式结合并抑制hRR。建立了对hRR R1亚基的目标选择性，为抑制这种关键酶提供了一种新颖的方法。

• Xanthates as Thiol Surrogates for Nucleophilic Substitution with Aryl Halides

  We herein report an unprecedented xanthate-based protocol for the preparation of aryl-alkyl thioethers. Heating xanthates with aryl halides and namely cesium carbonate in methanol provides the target thioethers in generally good yields within short reaction times. This method allows one to avoid contact with odorous thiols and also to introduce substituents of which the corresponding thiols are virtually

  我们在此报告了一种前所未有的基于黄原酸盐的制备芳基-烷基硫醚的方案。用芳基卤化物加热黄原酸酯，即甲醇中的碳酸铯，可在较短的反应时间内以通常良好的产率提供目标硫醚。这种方法可以避免与有气味的硫醇接触，并且还可以引入相应的硫醇实际上不可用或使用不方便的取代基。

  日期：2016.10.10

  An unprecedented rhodium-catalyzed selective cleavage of double alkyl-oxygen bonds of bis/tris(o-alkyloxyphenyl)phosphine has been realized, in which P atom functions as a. directing group and simple aryl acids are the methyl group acceptor to provide methyl esters and a quaternary phosphonium salt. The preliminary mechanism was investigated via an O-18 labeling experiment and stoichiometric reaction between a Rh-A crystal and an aromatic acid.

  Ribonucleotide reductase (RR), an established cancer target, is usually inhibited by antimetabolites, which display multiple cross-reactive effects. Recently, we discovered a naphthyl salicyl acyl hydrazone-based inhibitor (NSAH or E-3a) of human RR (hRR) binding at the catalytic site (C-site) and inhibiting hRR reversibly. We herein report the synthesis and biochemical characterization of 25 distinct
