The design, synthesis, and biological evaluation of new phosphodiesterase type 4 (PDE4) inhibitors, which possessed 7-(cyclopentyloxy)-6-methoxy 1,2,3,4-tetrahydroisoquinoline ring, were described. Compound 8 [(7-cyclopentyloxy)-6-methoxy-3,4-dihydroisoquinolin-2(1H)-yl)(4-hydroxy-3-methoxy-phenyl)methanone] showed the best inhibitory activity and good selectivity against PDE4B. The docking results
描述了具有7-(环戊氧基)-6-甲氧基1,2,3,4-四氢异喹啉环的新型4型磷酸二酯酶(PDE4)抑制剂的设计,合成和生物学评估。化合物8 [(7-环戊氧基)-6-甲氧基-3,4-二氢异喹啉-2(1 H)-基)(4-羟基-3-甲氧基-苯基)甲酮显示出最佳的抑制活性和对PDE4B的良好选择性。对接结果表明,化合物8的邻苯二酚二醚部分在与PDE4B蛋白形成完整的氢键方面起着关键作用,而分子的其余部分延伸到催化域中以阻止cAMP的进入并为抑制PDE4奠定了基础。 。化合物8 基于初步的结构-活性关系和分子模型研究,作为进一步研究的热门化合物将有很大的希望。
