In this present study, a series of 5-phenyl-2-furan and 4-phenyl-2-oxazole derivatives were designed and synthesized as phosphodiesterase type 4 (PDE4) inhibitors. In vitro results showed that the synthesized compounds exhibited considerable inhibitory activity against PDE4B and blockade of LPS-induced TNF-α release. Among the designed compounds, Compound 5j exhibited lower IC50 value (1.4 μM) against
在本研究中,设计并合成了一系列5-苯基-2-呋喃和4-苯基-2-恶唑衍生物,作为4型磷酸二酯酶(PDE4)抑制剂。体外结果表明,合成的化合物对PDE4B表现出相当大的抑制活性,并阻断LPS诱导的TNF- α释放。在设计的化合物中,化合物5j在体外酶法检测中对PDE4的IC 50值(1.4μM)低于母体咯利普兰(2.0μM),在体内也显示出良好的LPS诱发的哮喘/ COPD和败血症动物模型中的活性降低。对接结果表明,在苯环对位引入甲氧基,表现出与PDE4B的金属结合口袋结构域良好的相互作用,这有助于增强抑制活性。
