  1-Arylnaphthalene Lignan:  A Novel Scaffold for Type 5 Phosphodiesterase Inhibitor

  摘要：

  1-Arylnaphthalene lignan, which had been reported as a PDE4 inhibitor by Iwasaki, was disclosed as a new structural class of PDE5 inhibitors. The structural requirements for potent and specific PDE5 inhibition were revealed in a 1-arylnaphthalene lignan series, in which 1-(3-bromo-4, 5-dimethoxyphenyl)-5-chloro-3-[4-(2-hydroxyethyl)-1-piperazinylcarbonyl]-2-(methoxycarbonyl)naphthalene hydrochloride (27q) showed the most potent and specific inhibition (PDE5 inhibition IC50 = 6.2 nM, selectivity for PDE5 against PDE1, -2, -3, and -4 > 16 000). It is noteworthy that 27q has the best selectivities against PDE isoforms among PDE5 inhibitors so far reported. Compound 27q exhibited almost the same relaxant effects on rat aortic rings as sodium 1-[6-chloro-4-[(3,4-methylenedioxybenzyl)amino]quinazolin-2-yl]piperidine-4-carboxylate (35) (27q, EC50 = 0.10 mu M; 35, EC50 = 0.20 mu M) and was selected for further biological evaluation.

  A series of 1-aryl-2,3-bis(hydroxymethyl)naphthalene lignans have been synthesized and evaluated for their ability to selectively inhibit PDE IV isolated from guinea pig. Replacement of the 1-phenyl ring by a pyridone ring led to marked improvement of their selectivity for PDE IV over PDE III. The compounds that were most potent and selective involved those bearing an N-alkylpyridone ring at C-1. These

  已经合成了一系列的1-芳基-2,3-双（羟甲基）萘木酚素，并对其选择性抑制豚鼠分离的PDE IV的能力进行了评估。1-吡啶环被吡啶酮环取代导致其对PDE IV的选择性比PDE III显着提高。最有效和最具选择性的化合物涉及在C-1处带有N-烷基吡啶酮环的化合物。这些化合物还显示出有效的抗痉挛活性，而不会引起豚鼠心率的显着变化。最有效的化合物是6,7-二乙氧基-2，3-双（羟甲基）-1- [1-（2-甲氧基乙基）-2-氧代-吡啶-4-基] nap hth alene（17f），ED50值在豚鼠中，组胺诱导的和抗原诱导的支气管收缩分别为0.08和2.3 mg / kg iv。
