  Gold-Catalyzed Proto- and Deuterodeboronation

  摘要：

  A mild gold-catalyzed protodeboronation reaction, which does not require acid or base additives and can be carried out in "green" solvents, is described. As a result, the reaction is very functional-group-tolerant, even to acid- and base-sensitive functional groups, and should allow for the boronic acid group to be used as an effective traceless directing or blocking group. The reaction has also been extended to deuterodeboronations for regiospecific ipso-deuterations of aryls and heteroaryls from the corresponding organoboronic acid. Based on density functional theory calculations, a mechanism is proposed that involves nucleophilic attack of water at boron followed by rate-limiting B-C bond cleavage and facile protonolysis of a Au-sigma-phenyl intermediate.

  Novel indazole and benzimidazole analogues were designed and synthesized as tubulin inhibitors with potent antiproliferative activities. Among them, compound 12b exhibited the strongest inhibitory effects on the growth of cancer cells with an average IC50 value of 50 nM, slightly better than colchicine. 12b exhibited nearly equal potency against both, a paclitaxel-resistant cancer cell line (A2780/T

  设计并合成了新型吲唑和苯并咪唑类似物，作为具有有效抗增殖活性的微管蛋白抑制剂。其中，化合物12b对癌细胞的生长表现出最强的抑制作用，平均IC 50值为50 nM，略高于秋水仙碱。12b对紫杉醇抗性癌细胞系（A2780 / T，IC 50 = 9.7 nM）和相应的亲代细胞系（A2780S，IC 50 = 6.2 nM）表现出几乎相等的效力，因此在体外有效克服了对紫杉醇的抗性。12b的晶体结构通过X射线晶体学分析，将与微管蛋白复合的化合物拆分至2.45Å分辨率，并确认其直接结合至秋水仙碱位点。此外，12b在黑素瘤肿瘤模型中显示出显着的体内抗肿瘤功效，肿瘤生长抑制率分别为78.70％（15 mg / kg）和84.32％（30 mg / kg）。总的来说，这项工作表明12b是一种有前途的铅化合物，作为潜在的抗癌剂值得进一步研究。

  The conformationally restricted, spatially defined macrocyclic ring system of formula (I) is constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. Macrocycles described by this ring system I are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), inhibitory activity on enzymes or antimicrobial activity. In particular, these macrocycles show inhibitory activity on endothelin converting enzyme of subtype 1 (ECE-1) and/or the cysteine protease cathepsin S (CatS), and/or act as antagonists of the oxytocin (OT) receptor, thyrotropin-releasing hormone (TRH) receptor and/or leukotriene B4 (LTB4) receptor, and/or as agonists of the bombesin 3 (BB3) receptor, and/or show antimicrobial activity against at least one bacterial strain. Thus they are showing great potential as medicaments for a variety of diseases.

  A series of Pyrazolo[1,5-a]Pyrimidine analogs were designed and synthesized as novel tubulin inhibitors. Among them, compounds 1a and 1b showed the highest antiproliferative activity against a panel of cancer cell lines with average IC50 values of 24.8 nM and 28 nM, respectively. We determined the crystal structures of 1a and 1b in complex with tubulin and confirmed their direct binding to the colchicine
