  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).

  Selective PDE4 inhibition is achieved by aryl and heteroaryl pyrazole compounds. The compounds exhibit improved PDE4 inhibition as compared to compounds such as rolipram and show selectivity with regard to inhibition of other classes of PDEs.

  选择性PDE4抑制是通过芳基和杂环基吡唑化合物实现的。与罗利普兰（rolipram）等化合物相比，这些化合物表现出更好的PDE4抑制作用，并且在抑制其他类PDE时表现出选择性。

  α‐Alkoxycarbonyl and α‐aminocarbonyl compounds are good substrates for the recently developed tosylhydrazide‐promoted Pd‐catalyzed cross‐coupling of carbonyls with aryl halides. The reaction gives rise to enol ethers and enamines, respectively, which are useful synthetic intermediates in heterocyclic synthesis. Otherwise, they can be hydrolyzed to give α,α‐disubstituted aldehydes.

  α-取代很好：α-烷氧羰基和α-氨基羰基化合物是最近开发的甲苯磺酰肼促进的Pd催化的羰基与芳基卤化物交叉偶联的良好底物。该反应分别产生烯醇醚和烯胺，它们是杂环合成中有用的合成中间体。否则，可以将它们水解得到α，α-二取代醛。

  Highly enantioselective syntheses of two important γ-aminobutyric acid (GABA) analogues, the antispastic drug (-)-(R)-Baclofen and the antidepressant agent (-)-(R)-Rolipram, are reported. Key-steps in both syntheses are the Rh-catalyzed asymmetric 1,4-additions of arylboronic acids to 4-aminobut-2,3-enoic acid derivatives.

  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
