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
描述了一系列新颖的4,5-二氢-4-氧代-2-(取代的氨基)-3-呋喃羧酸,盐,酯和酰胺的合成。在大鼠介导的皮肤血管通透性和活性过敏试验中进行测试时,标题化合物表现出中度至强效的抗过敏活性。出现了[2-反式-(4-甲基苯基)环丙基]氨基类似物53作为最有活性的衍生物。因此,当以100 mg / kg的剂量腹膜内给予大鼠时,它可抑制血清素,组胺和缓激肽等介质的作用达100%。在大鼠的主动过敏反应测定中,腹膜内给药后,化合物30以100 mg / kg的剂量将水肿抑制了81%。
