The present invention relates to a compound represented by the formula (I’) wherein A is a benzene ring optionally having substituents, R1, R2a and R3 are each a hydrogen atom, a hydrocarbon group optionally having substituents or a heterocyclic group optionally having substituents, R1 and R2a may form a ring via X, when R1 and R2a form a ring via X, R1 and R2a are each a bond or a divalent C1-5 acyclic hydrocarbon group optionally having substituents, and X is a bond, an oxygen atom, an optionally oxidized sulfur atom or an imino group optionally having a substituent, provided that R1, R2a and X are not bonds at the same time, or a salt thereof, and an agent for inhibiting kinase (phosphorylation enzyme), which contains this compound or a prodrug thereof. The compound of the present invention has an inhibitory activity against kinase such as a vascular endothelial growth factor receptor (VEGFR) and the like, and is useful as an agent for the prophylaxis or threatment of cancer and the like.

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.
