  Structural Studies on Bioactive Compounds. 32. Oxidation of Tyrphostin Protein Tyrosine Kinase Inhibitors with Hypervalent Iodine Reagents

  摘要：

  Hydroxylated styrenes (tyrphostins) undergo oxidation by hypervalent iodine oxidants such as [(diacetoxy)iodo]benzene (DAIB) to give a range of products depending on the structure of the phenolic substrate, the solvent, the oxidant stoichiometry, and the purification strategy. Conditions have been developed to modify the phenolic component of the tyrphostin without affecting the appended substituted-vinyl moiety. Novel products include: unstable 2-acyloxy-2-methoxy-4-(substituted-vinyl)cyclohexadienones and their rearrangement products 2-acyloxy-4-hydroxy-3 -methoxy-1-(substituted-vinyl)benzenes; phenyliodoniophenolates and their rearrangement products iodophenoxytyrphostins; and 3,3'-dialkoxy-2,2'-dihydroxy-5,5'-di(substituted-vinyl)biphenyls. None of these oxidation products displayed enhanced activity in vitro in the NCI 60-cell line panel or in a panel of human breast cancer cell lines, compared to their tyrphostin precursors. The inhibitory activity of three representative tyrphostins (3e,n, 28) was not modulated by aerobic/anaerobic conditions in MCF-7 and MDA 468 cells and was independent of EGFR status in clones of ZR75B cells transfected with this receptor. Basal growth of MCF-7 cells was unaffected by co-administration of the growth factors EGF, TGF-alpha, IGF-I, and IGF-II, and the new agents did not inhibit EGFR and c-erbB2 autaphosphorylation in cell lysates from MDA 468 or SkBr3 cells, respectively, suggesting that receptor tyrosine kinases are not targets for these compounds. Growth stimulation by the tyrphostin 3n in the ER+ breast cell lines MCF-7, T47D, and ZR75-1 was abolished by 1 mu M tamoxifen, suggesting that this compound has estrogen agonist activity.

  使用各种醛和活性亚甲基化合物的高活性铜 (I)-硫属元素酮催化 Knoevenagel 缩合反应

  摘要：

  已经报道了第一个铜 (I) 硫属元素酮催化的 Knoevenagel 缩合反应。没有发现在 Knoevenagel 缩合催化中使用这种铜-硫属元素酮络合物类的说明。因此，铜(I)双(苯并咪唑-2-硫属元素酮)催化剂[Cu( L 1 ) 4 ] + BF 4 - ( 1 ) 和[Cu( L 2 ) 4 ] + BF 4 - ( 2 ) ( L 1  =双(1-异丙基-苯并咪唑-2-selone)-3-乙基；L 2 =双（1-异丙基-苯并咪唑-2-硫酮）-3-乙基）已被用作Knoevenagel缩合反应中的催化剂。这些铜 (I) 硫属元素酮催化剂在芳基醛和活性亚甲基化合物的催化 Knoevenagel 缩合反应中表现出高效率。特别是配合物2表现出最好的催化活性。已经用 22 种不同的分子研究了催化反应的范围。已经描述了具有富电子或缺乏芳基醛的各种类型的底物的优异催化活性。本研究的特点是反应条件
