A series of new N-phenylbenzamido acid derivatives was synthesized and evaluated for their ability to inhibit the IgE-mediated passive cutaneous anaphylaxis in the rat (PCA), as well as for their capacity to inhibit gastric mucosal damage induced by the oral administration of absolute alcohol in the rat. Some of these new derivatives exhibit potent antiallergic and cytoprotective activity, 20-80 times
合成了一系列新的N-苯基苯甲酰胺酸衍生物,并评估了它们抑制IgE介导的大鼠被动皮肤过敏反应(PCA)的能力,以及它们抑制口服绝对剂量诱导的胃粘膜损伤的能力。大鼠饮酒。这些新衍生物中的一些表现出有效的抗过敏和细胞保护活性,比参考的糖基葡萄糖酸二钠(DSCG)高20-80倍。讨论了构效关系。该系列中更有效的化合物之一,即4-(1H-四唑-5-基)-N- [4-(1H-四唑-5-基)苯基]苯甲酰胺的抗过敏活性(化合物44,CR 2039 )在体内进行了进一步评估。该化合物拮抗雾化的卵清蛋白在麻醉的和有意识的IgE致敏豚鼠中引起的支气管收缩,ID50为3.7 mg /动物(气管吹入)和20 mg / kg(im)。在空腹动物急性口服高渗氯化钠溶液或乙酸引起的胃溃疡模型中,评估了进一步的细胞保护作用。在实验中使用的模型中,CR 2039是有效的,而DSCG似乎没有任何保护活性。这种有效的抗过敏和粘膜
