The synthesis of a series of novel 4,5-dihydro-4-oxo-2-(substituted amino)-3-furancarboxylic acids, salts, esters, and amides is described. The title compounds when tested in the mediator-induced dermal vascular permeability and active anaphylaxis assays in rats demonstrated moderate to potent antiallergic activity. The [2-trans-(4-methylphenyl)cyclopropyl]amino analogue 53 emerged as the most active
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.
