一种由下式表示的5，8-二氢-5-氧代吡啶并[2，3-d]嘧啶衍生物，其中R1表示氢或低级烷基; R2表示氢、低级烷基、羟基、卤素原子、低级烷氧基、氨基或低级烷硫基; R3表示氢、低级烷基、羟基、低级烷氧基、低级烷硫基或下式所示的基团（其中R“代表氢、烷基、环烷基、氨基、羟烷基或烷基取代的氨基烷基，R”代表氢或烷基，R ′和R ″可以是相同或不同的基团，R ′和R ″可以键合在一起形成含氮杂原子的5-或6-元杂环）;和R4代表氢或烷基。此类衍生物可用作抗菌剂。
A 5,8-dihydro-5-oxopyrido [2,3-d] pyrimidine derivative represented by the following formula WHEREIN R1 stands for hydrogen or a lower alkyl radical; R2 stands for hydrogen, a lower alkyl radical, hydroxyl group, a halogen atom, a lower alkoxy radical, an amino radical or a lower alkylthio radical; R3 stands for hydrogen, a lower alkyl radical, hydroxyl group, a lower alkoxy radical, a lower alkylthio radical or a radical represented by the formula (WHEREIN R' stands for hydrogen, an alkyl radical, a cycloalkyl radical, an amino radical, a hydroxyalkyl group or an alkyl substituted amino alkyl radical, and R'' stands for hydrogen or an alkyl radical, R' and R'' may be the same or a different radical and R' and R'' may bond together to form a 5- or 6- membered heterocyclic ring containing a nitrogen hetero atom); and R4 stands for hydrogen or an alkyl group. Such derivatives are useful as antibacterial agents.
