  摘要：

  最近，我们报道了4-儿茶酚取代的顺-（+/-）-4a，5,6,7,8,8a-六-和顺-（+/-）-4a，5,8,8a-四氢-2H-酞嗪-1-酮显示出对磷酸二酯酶（PDE4）活性的有效抑制作用，而相应的反式外消旋混合物仅表现出弱至中等的活性。为了确定各个顺式对映异构体的绝对构型和PDE4抑制活性，已合成了几种旋光性邻苯二氮酮。用作起始原料的各种γ-酮酸的对映异构体通过形成非对映异构体盐以经典方式拆分，然后以对映选择性的方式将其分别转化为旋光性酞嗪酮。顺式六氢酞嗪酮（+）-12的（+）-对映体的绝对构型通过X射线晶体学测定。发现在4a和8a位置的碳原子分别具有S-和R-构型。在本系列的六氢和四氢邻苯二氮酮中，观察到了对PDE4抑制的立体选择性。邻苯二氮酮的顺-（+）-对映体显示高抑制活性，而它们的（-）-对映体仅显示弱至中等活性。对于顺式（-）-类似物，所有顺式（+）-邻苯二氮酮都可能具有（4

  Novel Selective PDE4 Inhibitors. 2. Synthesis and Structure−Activity Relationships of 4-Aryl-Substituted cis-Tetra- and cis-Hexahydrophthalazinones

  摘要：

  A series of 4-aryl-substituted cis-4a,5,8,8a-tetra- and cis-4a,5,6,7,8,8a-hexahydro-2H-phthalazin-1-ones with high inhibitory activity toward cAMP-specific phosphodiesterase (PDE4) was synthesized. To study structure-activity relationships various substituents were introduced to the 2-, 3-, and 4-positions of the 4-phenyl ring. Substitution at the 4-position of the phenyl ring was restricted to a methoxy group, probably due to unfavorable steric interactions of larger groups with the binding site. The introduction of many alkoxy substituents including distinct ring systems and functional groups was allowed to the 3-position. It was found that in general the cis-4a,5,8,8a-tetrahydro-2H-phthalazin-1-ones are more potent than their hexahydrophthalic counterparts, the best activity residing in (4-imidazol-1-yl-phenoxy)butoxy analogue 16o (pIC(50) = 9.7).

  shows large differences which shows the potential for obtaining parasite selective PDE inhibitors. The results of these studies support the pharmacological validation of the Trypanosome PDEB family as novel therapeutic approach for HAT and provide as well valuable information for the design of potent TbrPDEB1 inhibitors that could be used for the treatment of this disease.

  锥虫磷酸二酯酶B1和B2（TbrPDEB1和TbrPDEB2）在布鲁氏锥虫的生命周期中起着重要作用，布鲁氏锥虫是人类非洲锥虫病（HAT）的致病性寄生虫，也被称为非洲昏睡病。击倒这两种酶会导致细胞周期停滞，并且对寄生虫具有致命性。最近，我们报道了phenylpyridazinone，NPD-001，具有低纳摩尔IC 50个在两个TbrPDEB1值（IC 50：4 1nM）和TbrPDEB2（IC 50：3 nM）的（。传染病杂志 2012，206（229）。在这项研究中，我们现在报告一系列作为TbrPDEB1抑制剂的苯基哒嗪酮类似物的第一个结构活性关系。还显示了选择的化合物是抗寄生虫的。重要的是，观察到TbrPDEB1 IC 50和EC 50与整个寄生虫之间具有良好的相关性。对TbrPDEB1和人PDE上所选化合物的SAR的初步分析显示出很大的差异，这显示出获得寄生虫选择性PDE抑制剂的潜力

  As there is a continuous need for novel anti-infectives, the present study aimed to fuse two modes of action into a novel 3-nitroimidazo[1,2-b]pyridazine scaffold to improve antiparasitic efficacy. For this purpose, we combined known structural elements of phosphodiesterase inhibitors, a target recently proposed for Trypanosoma brucei and Giardia lamblia, with a nitroimidazole scaffold to generate

  由于对新型抗感染药物的持续需求，本研究旨在将两种作用模式融合到新型 3-硝基咪唑并[1,2- b ]哒嗪支架中，以提高抗寄生虫功效。为此，我们将磷酸二酯酶抑制剂的已知结构元素（最近提出的针对布氏锥虫和贾第鞭毛虫的靶标）与硝基咪唑支架结合以产生亚硝化应激。这些化合物在体外针对一组原生动物寄生虫进行了评估，即兰氏贾第鞭毛虫、布氏锥虫、克氏锥虫、婴儿利什曼原虫和恶性疟原虫以及对 MRC-5 细胞的细胞毒性。有趣的是，获得了针对G. lamblia的选择性亚纳摩尔活性，并且通过测试具有和不具有硝基的几种类似物，表明硝基的存在而非 PDE 抑制是低 IC 50值的原因这些新颖的化合物。3-硝基咪唑并[1,2- b ]哒嗪系列的关键化合物具有良好的类药物特性（低分子量、cLogP (1.2–4.1) 和低极性表面积），可被视为进一步研究的有价值的产物。抗贾第虫病药物的探索与开发。

  8a-tetrahydro-2H-phthalazin-1-ones show potent inhibition of phosphodiesterase (PDE4) activity, while the corresponding trans racemic mixtures exhibit only weak to moderate activity. To determine the absolute configuration and PDE4 inhibitory activity of the individual cis-enantiomers, several optically active phthalazinones have been synthesized.
