呋喃嘧啶衍生物是重要的含氮杂环化合物,其类似嘌呤结构具有良好的杀菌、抗病毒、防辐射、抗凝血作用以及具有除草、杀虫活性,是一类具有良好生物活性和药理活性的杂环化合物,早在20世纪30年代就备受人们的关注。研究表明一些呋喃并嘧啶衍生物通过抑制血管内皮细 Furopyrimidine derivatives are important nitrogen-containing heterocyclic compounds, which have the similar bactericidal, antiviral, radiation-proof and anticoagulant activities as purine structures and herbicidal and insecticidal activity, and are a class of compounds having good biological activities and pharmacological activities Of heterocyclic compounds, as early as the 1930s on the much attention. Studies have shown that some furopyrimidine derivatives through the inhibition of vascular endothelial thin
