  Design, Synthesis, and Structure−Activity Relationships of Haloenol Lactones:  Site-Directed and Isozyme-Selective Glutathione S-Transferase Inhibitors

  摘要：

  Overexpression of glutathione S-transferase (GST), particularly the GST-pi isozyme, has been proposed to be one of the biochemical mechanisms responsible for drug resistance in cancer chemotherapy, and inhibition of overexpressed GST has been suggested as an approach to combat GST-induced drug resistance. 3-Cinnamyl-5(E)-bromomethylidenetetrahydro-2-furanone (1a), a lead compound of site-directed GST-pi inactivator, has been shown to potentiate the cytotoxic effect of cisplatin on tumor cells. As an initial step to develop more potent and more selective haloenol lactone inactivators of GST-pi, we examined the relationship between the chemical structures of haloenol lactone derivatives and their GST inhibitory activity. A total of 16 haloenol lactone derivatives were synthesized to probe the effects of (1) halogen electronegativity, (2) electron density of aromatic rings, (3) molecular size and rigidity, (4) lipophilicity, and (5) aromaticity on the potency of GST-pi inactivation. The inhibitory potency of each compound was determined by time-dependent inhibition tests, and recombinant human GST-pi was used to determine their inhibitory activity. Our structure-activity relationship studies demonstrated that (1) reactivity of the halide leaving group plays a weak role in GST inactivation by the haloenol lactones, (2) aromatic electron density may have some influence on the potency of GST inactivation, (3) high rigidity likely disfavors enzyme inhibition, (4) lipophilicity is inversely proportional to enzyme inactivation, and (5) an unsaturated system may be important for enzyme inhibition. This work facilitated understanding of the interaction of GST-pi with haloenol lactone derivatives as site-directed and isozyme-selective inactivators, possibly potentiating cancer chemotherapy.

• Cobalt Carbonyl-Mediated Carbocyclizations of Enynes:  Generation of Bicyclooctanones or Monocyclic Alkenes

  Depending on the thermolytic conditions, dicobalthexacarbonyl-complexed enynes underwent cyclizations to provide different carbocyclic frameworks. Bicyclopentanones were formed from enyne-Co2(CO)6 complexes, or from enynes that were treated with Co2(CO)8, or more effectively, with Co4(CO)12 in an alcoholic solvent under a H2 or N2 atmosphere. This transformation proceeded via a sequential cyclocarbonylation

  取决于热解条件，二钴六羰基复合的烯炔进行环化以提供不同的碳环骨架。双环戊酮是由烯炔-Co2（CO）6配合物形成的，或者由在乙醇溶剂中在H2或N2气氛下用Co2（CO）8或更有效地用Co4（CO）12处理的烯炔形成。该转化通过顺序的环羰基化和1，4-还原进行，并且是使用羰基钴簇的第一个解释。在这些条件下，大概生成了氢化钴，其介导了烯酮还原为饱和酮。相反，在双氢戊烯酮产物之外，在氢气气氛下在甲苯中二巴杂六羰基络合物的炔炔的热解导致它们的还原环化以中等收率形成单环烯烃。在某些情况下，向反应中加入氢硅烷会完全抑制双环戊烯酮的形成。前者的结果证明了在环加成反应之后发生的反应，而后者描述了在Pauson-Khand反应途径中正常途径中断的另一个例子。

  Hydroindation of allenes and radical cyclization of 1,2,7-trienes (allenenes) were accomplished by HInCl2 with high regioselectivity to afford a variety of cyclic compounds. The resulting vinylic indiums could be used for successive coupling reactions in a one-pot procedure. The use of HInCl2 generated slowly in situ is extremely effective for the radical cyclization.

  所有烯的氢化及1,2,7-三烯（烯烯）的自由基环化可通过HInCl2以高区域选择性实现，从而获得多种环状化合物。生成的乙烯基铟可用于一锅法的连续偶联反应。使用缓慢原位生成的HInCl2对自由基环化极为有效。

  DOI：10.1021/ol060606d

  日期：2006.5.1

  [reaction: see text] The skeletal reorganization of enynes is achieved by the presence of InCl(3) as the catalyst. The reaction of enynes having a terminal acetylenic moiety proceeds in a stereospecific manner to give 1-vinylcycloalkenes. The reaction of enynes containing an alkyl group on the acetylenic terminal carbon resulted in a new type of skeletal reorganization to give 1-allylcycloalkenes,
