Their ability to inhibit histamine release from these cells and from a mucosal mast cell preparation has also been evaluated. These compounds, nedocromil sodium (TILADE 86) and minocromil (the free acid of 72), are at present undergoing therapeutic evaluation. The rationale for the screening procedure and the relevance of the second carboxylic acid function of these dibasic acids to receptor binding are
已经合成了许多潜在用于哮喘局部治疗的抗过敏性吡喹啉二羧酸衍生物。所有化合物均已针对大鼠被动皮肤过敏反应和狗低血压筛查进行了评估。这是后一种筛选方法用于识别抗过敏剂的第一个详细说明。两种化合物,9-乙基-6钠,9-二氢-4,6-二氧代-10-丙基-4H-吡喃[3,2-g]喹啉-2,8-二羧酸酯(86)和6-(甲氨基二钠) )-4-氧代-10-丙基-4H-吡喃并[3,2-g]-喹啉-2,8-二羧酸酯(72),并进一步评估了它们诱导78000分子量相关蛋白磷酸化的能力与大鼠腹膜肥大细胞。还已经评估了它们抑制组胺从这些细胞和粘膜肥大细胞制剂中释放的能力。这些化合物,奈多克罗米钠(TILADE 86)和米诺克罗米尔(72的游离酸),目前正在接受治疗评估。讨论了筛选程序的原理以及这些二元酸的第二羧酸功能与受体结合的相关性。
