  摘要：

  微管是抗癌疗法中经过充分验证的目标。然而，微管结合剂（TBA）的临床开发一直受到毒性和化疗抗性问题的阻碍，因此有必要寻找新的TBA。在此，我们报告了一种新型细胞通透性、微管不稳定性分子的鉴定——4,5,6,7-四氢-1H-吲唑-3-羧酸[1-甲苯基-甲-(E)-亚基]-酰肼（命名为Suprafenacine，SRF）。SRF是通过对注释化学库的计算机筛选鉴定的，它被证明在秋水仙素结合位点与微管结合并抑制聚合。这导致G2/M细胞周期阻滞和通过线粒体介导的凋亡途径的细胞死亡。细胞死亡之前是线粒体膜电位的丧失，JNK介导的Bcl-2和Bad的磷酸化，以及caspase-3的激活。有趣的是，SRF被发现能选择性抑制癌细胞增殖，并通过其绕过多药耐药转运蛋白P-糖蛋白的能力对耐药癌细胞有效。总的来说，我们的结果表明SRF具有作为抗癌化疗药物的潜力，并为开发改进的抗癌药物提供了另一种支架结构。

  Reaction of 2-oxocylalkaneglyoxylate esters with N-phenylmethyleneaniline yields spiro compounds such as 2-aza-3,4,6,-trioxo-1,2-diphenylspiro[4.4]nonane 4 and cycloalkane-2-aza-3,4,6-trioxo-1,2-diphenylspiro-[4.5]decanes 5–7. These undergo solvolytic opening of the the oxocycloalkane ring to yield 4-substituted-1,5-dihydro-3-hydroxy-2-oxo-1,5-diphenyl-2H-pyrroles 12–17.

  phosphine-catalyzed transformation has been developed for the synthesis of chiral cyclobutene triesters and fluorinated spirocyclic compounds. The strategy involved a P(III)/P(V) redox cycling process, via in situ reduction of phosphine oxide with phenylsilane. This catalytic methodology has enabled the enantioselective synthesis of functionalized cyclobutenes (24 examples, up to 94% ee). On the occasion of the

  Various ()-2-hydroxy acids such as ()-2-hydroxy-3-enoic-, 3,5-dienoic-, 4-oxo-, ()-3-hydroxy and some others were prepared on a scale up to 0.12 mol by biocatalytic reduction of the corresponding 2-oxo acids with P. vulgaris and hydrogen gas and/or formate as electron donors. With the exception of the 2-hydroxy-4-oxo acids it could be proved that the enantiomeric excess is > 97%. For the 4-oxo derivatives

  各种（）-2-羟基酸如（）-2-羟基-3-烯酸，3,5-二烯酸，4-氧代，（）-3-羟基等，其制备规模可达到通过以寻常的毕赤酵母和氢气和/或甲酸作为电子给体，对相应的2-氧代酸进行生物催化还原，可得到0.12摩尔。除2-羟基-4-氧代酸外，可以证明对映体过量> 97％。对于4-氧代衍生物，可以假定该对映体过量。分离出的产物的产率很高，因为它们是从相当少量的生物催化剂中分离出来的，并且缓冲液的浓度很低，获得的产物浓度在0.1–0.24 M的范围内。在15–20小时内形成1 mmol的产品，约20–40 mg（干重）寻常型毕赤酵母 单元格是必需的。
