  将硒掺入DNA编码库中的化学。

  摘要：

  常规的直接CH H硒化反应具有简单的硒化，有限的原子经济性和复杂的反应体系。在这项工作中，我们设计了苯并硒氮酮作为一种新型的双功能硒化物试剂，用于在铑（III）催化下进行脱氢和脱氢CHH硒化反应。我们表明，使用苯并硒氮唑酮允许以快速，有效的方式生产一系列含有相邻氨基酰基的硒化产物，并具有较高的原子经济性。通过利用酰胺官能团作为亲核试剂，导向基团和酰胺偶联伙伴，证明了该方法的合成应用。这项工作显示出在促进快速构建含硒DNA编码化学文库（SeDEL）方面的巨大潜力，并为开发含硒药物奠定了基础。

  基于多奈哌齐和埃布塞林融合的抗阿尔茨海默氏病多靶标配体的合成和评价

  摘要：

  通过将胆碱酯酶抑制剂多奈哌齐和抗氧化剂依布硒啉融合获得的一系列新化合物被设计为针对阿尔茨海默氏病的多靶标配体。体外测定表明，这些分子中的某些分子没有表现出强效的胆碱酯酶抑制活性，但确实具有与依布硒仑相关的各种其他药理作用。在这些分子中，发现化合物7d是最有效的乙酰胆碱酯酶抑制剂之一（电泳电乙酰胆碱酯酶的IC 50值为0.042μM，人乙酰胆碱酯酶的IC 50值为0.097μM），是一种强丁酰胆碱酯酶抑制剂（IC 50值为1.586μM），拥有快速的H 2 O 2和过氧亚硝酸盐清除活性，谷胱甘肽过氧化物酶样活性（ν 0 = 123.5μM分钟-1），并且是哺乳动物的TrxR的基板。小鼠毒性试验显示，剂量高达2000 mg / kg时无急性毒性。根据体外血脑屏障模型，7d能够穿透中枢神经系统。

  A novel series of compounds obtained by fusing the metal-chelating agent clioquinol and the antioxidant ebselen were designed, synthesized and evaluated as multi-target-directed ligands against Alzheimer's disease (AD). Specifically, compared with their parent compounds clioquinol and ebselen, these hybrids demonstrated significant potency in inhibiting self- and Cu(II)-induced amyloid-β (Aβ) aggregation

• Inhibition of thioredoxin reductase by a novel series of bis-1,2-benzisoselenazol-3(2H)-ones: Organoselenium compounds for cancer therapy

  Thioredoxin reductase (TrxR) is critical for cellular redox regulation and is involved in tumor proliferation, apoptosis and metastasis. Its C-terminal redox-active center contains a cysteine (Cys497) and a unique selenocysteine (Sec498), which are exposed to solvent and easily accessible. Thus, it is becoming an important target for anticancer drugs. Selective inhibition of TrxR by 1,2-(bis-1,2-benzisoselenazol-3(2H)-one)ethane (4a) prevents proliferation of several cancer cell lines both in vivo and in vitro. Using the structure of 4a as a starting point, a series of novel bis-1,2-benzisoselenazol-3(2H)-ones was designed, prepared and tested to explore the structure-activity relationships (SARs) for this class of inhibitor and to improve their potency. Notably, 1,2-(5,5'-dimethoxybis(1,2-benzisoselenazol-3(2H)-one))ethane (12) was found to be more potent than 4a in both in vitro and in vivo evaluation. Its binding sites were confirmed by biotin-conjugated iodoacetamide assay and a SAR model was generated to guide further structural modification. (C) 2012 Elsevier Ltd. All rights reserved.

  The two different types of steroidal benzisoselenazolone hybrids were synthesized by incorporating benzisoselenazolone scaffold into dehydroepiandrosterone and B-norcholesterol. The antiproliferative activity of the synthesized compounds against some carcinoma cell lines were investigated. The results showed that some of these compounds have better inhibitory activity than abiraterone on the proliferation of tumor cells associated with human growth hormone, and have less cytotoxicity on normal human cells. In particular, the IC50 values of the compound 8a and 8f are 5.4 and 6.5 mu mol/L against human ovarian carcinoma (SKOV3) cell line, and possess SI values of 13.9 and 10.5, respectively. The information obtained from the studies may be useful for the design of novel chemotherapeutic drugs.

  To identify novel multi-target-directed drug candidates for the treatment of cancer, a series of benzoselenazole-stilbene hybrids were synthesised by combining the pharmacophores of resveratrol and ebselen. The biological assay indicated that all of the hybrids exhibited antiproliferative activities against four human cancer cell lines and demonstrated good TrxR inhibitory activities. The mechanism of cell apoptosis was investigated in G2/M cell cycle arrest induced by compound 6e and the apoptosis of the human liver carcinoma Bel-7402 cell line. The significant increase in intracellular ROS confirmed that compound 6e was capable of causing oxidative stress-induced apoptosis in cancer cells. Our results support the potential of compound 6e as a candidate for further studies examining the development of novel drugs for cancer treatment. (C) 2015 Elsevier Masson SAS. All rights reserved.
