A series of pyrazole and triazole derivatives containing 5-phenyl-2-furan functionality were designed and synthesized as phosphodiesterase type 4 (PDE4) inhibitors. The bioassay results showed that title compounds exhibited considerable inhibitory activity against PDE4B and blockade of LPS-induced TNFα release. Meanwhile, the activity of compounds containing 1,2,4-triazole (series II) was higher than
设计并合成了一系列含有5-苯基-2-呋喃官能团的吡唑和三唑衍生物,作为4型磷酸二酯酶(PDE4)抑制剂。生物测定结果表明,标题化合物显示出相当大的抑制活性对PDE4B和LPS诱导的TNF阻断α释放。同时,含1,2,4-三唑的化合物(II系列)的活性高于与吡唑连接的衍生物(I系列)的活性。初步的结构-活性关系研究和对接结果表明,化合物IIk的1,2,4-三唑部分在与PDE4B蛋白形成完整的氢键和π–π堆积相互作用方面起着关键作用,而分子的其余部分扩展到催化域中以阻止cAMP的进入,并为抑制PDE4奠定了基础。根据初步的结构-活性关系和分子模型研究,化合物IIk有望作为进一步研究的成功化合物。
