To provide a novel furanone derivative, and a medicine including the same. The furanone derivative is represented by the formula (I):
wherein A represents —COOR1 or a hydrogen atom; R1 represents a hydrogen atom, an optionally substituted hydrocarbon group, or an optionally substituted heterocycle; R2 and R3 are the same or different and each independently represent a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted phenyl group, an optionally substituted heterocycle, an optionally substituted heterocyclic fused ring, or an optionally substituted amino group; or alternatively, R2 and R3, taken together with the nitrogen atom to which they are attached, may form an optionally substituted heterocycle or an optionally substituted heterocyclic fused ring; and R4 represents a hydrogen atom or a halogen atom; with the proviso that when A represents —COOR1, R2 and R3 are not optionally substituted amino groups at the same time, and when A represents a hydrogen atom, R3 represents a hydrogen atom.
提供一种新的呋喃酮衍生物,以及包括该衍生物的药物。该呋喃酮衍生物由式(I)表示:其中,A代表—COOR1或氢原子;R1代表氢原子、可选取代的烃基或可选取代的杂环;R2和R3相同或不同,且每个独立地代表氢原子、可选取代的烃基、可选取代的苯基、可选取代的杂环、可选取代的杂环融合环或可选取代的氨基;或者,R2和R3连同它们所连接的氮原子可以形成可选取代的杂环或可选取代的杂环融合环;R4代表氢原子或卤素原子;但是,当A代表—COOR1时,R2和R3不能同时为可选取代的氨基,当A代表氢原子时,R3代表氢原子。
