tryptophan in suppression of mast cell activation is established. Hence, we prepared constrained analogs of tryptophan, which are derivatives of 2,3,4,9‐tetrahydrospiro‐β‐carboline‐3‐carboxylic acid, and evaluated them for ex vivo inhibition of compound 48/80‐induced mast degranulation activity. By comparing IC50 (μM) values with that of the standard drug sodium cromoglycate (IC50 = 0.489 ± 0.003 μM), compounds
肥大细胞脱颗粒在哮喘、湿疹、过敏性鼻炎、结膜炎以及过敏性休克等多种疾病中起着重要作用;因此,开发新的肥大细胞稳定剂的需求尚未得到满足。报道的肥大细胞稳定剂具有杂环部分和酸性基团。此外,确定了色氨酸在抑制肥大细胞活化中的作用。因此,我们制备了色氨酸的受限类似物,它们是 2,3,4,9-四氢螺-β-咔啉-3-羧酸的衍生物,并评估它们对化合物 48/80 诱导的肥大脱粒活性的体外抑制作用。通过将 IC50 (μM) 值与标准药物色甘酸钠 (IC50 = 0.489 ± 0.003 μM) 的值进行比较,具有庞大基团的化合物如庚基(化合物 9;IC50 = 0.389 ± 0.015 μM)和辛基(化合物 10;IC50 = 0 . 354 ± 0.023 μM) 被发现具有与色甘酸钠相似的效力。此外,还发现氯丙基(化合物 16;IC50 = 0.382 ± 0.083 μM)和苯甲酰基衍生物(化合物
