Novel Selective PDE IV Inhibitors as Antiasthmatic Agents. Synthesis and Biological Activities of a Series of 1-Aryl-2,3-bis(hydroxymethyl)naphthalene Lignans
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。

5,6-Dimethoxy isobenzofuran is generated from the dimethylacetal of 6-hydroxymethyl veratraldehyde and intercepted by a variety of dienophiles to produce the expected oxygen-bridged adducts in good yield. Many of the latter are easily aromatised to naphthalenes.
