  Antipsoriatic anthrones with modulated redox properties. 1. Novel 10-substituted 1,8-dihydroxy-9(10H)-anthracenones as inhibitors of 5-lipoxygenase

  摘要：

  The syntheses, the biological evaluation, and the structure-activity relationships of a novel series of 1,8-dihydroxy-9(10H)-anthracenones bearing acyl-, alkyl-, or alkylidene-linked aromatic substituents in the 10-position are described. The phenylacyl and phenylalkylidene analogs were far more potent inhibitors of 5-lipoxygenase (5-LO) from bovine polymorphonuclear leukocytes (IC50 values in the 10(-7) M range) than the antipsoriatic drug anthralin, whereas phenylalkyl analogs were only weak inhibitors. Among the active compounds were both potent generators of hydroxyl radicals, as determined by deoxyribose degradation, and strong reducers of the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH). However, several derivatives of this series maintained 5-LO inhibitory activity but did not generate hydroxyl radicals and were not reactive with DPPH. In particular, phenylacyl analogs were also 6 times more efficient in inhibition of lipid peroxidation in model membranes than anthralin. Structure-activity relationships have shown that the presence of free phenolic groups in the attached aromatic ring is beneficial but not required for 5-LO inhibitory potency. The inhibitory potency in the 10-phenylacyl series increased with the length of the acyl chain with three methylene units being the optimum, suggesting a specific enzyme interaction which would not be expected for nonspecific redox inhibitors.

  with ferrous sulfate. C-C bond scission and radical formation was followed by dimerization of the radicals formed. Ozonides reacted similarly. Acyclic and cyclic olefins, including a cyclic enol ether, gave rise to a range of α,ω-disubstituted products in modest yields. By using ferric chloride, ω-chloro esters were obtained from the alkoxy hydroperoxides derived from olefinic esters.

  背景：H 3受体拮抗剂被认为是治疗阿尔茨海默氏病，注意力缺陷多动障碍，记忆和学习缺陷以及癫痫症的潜在药物。有效的H 3受体拮抗剂的最初开发集中于天然配体组胺的广泛修饰。然而，已显示含咪唑的配体与细胞色素P450酶的抑制有关，该抑制是由于在酶的活性位点上咪唑氮络合至血红素铁而引起的。由于这些原因，迫切需要开发有效的非咪唑H 3受体拮抗剂。 目的：以前，我们报道了一系列有效的组胺H 3受体非咪唑拮抗剂的合成和体外药理学表征，这些拮抗剂属于取代的2-噻唑-4-正丙基哌嗪类。该族的先导化合物1是带有乙基氨基甲基丙基链的衍生物。 方法：为了增加亲脂性，这将帮助配体穿过血脑屏障，我们合成了一系列新的2-噻唑-4-n-丙基哌嗪，其中的乙基氨基甲基丙基部分被对位取代的-一个未取代的苯环和噻唑环的4和5位上的ω--苯基烷基取代基。使用电收缩豚鼠空肠在体外测试所有化合物的H 3拮抗作用。 结果：呈现的系列3d
