from different plants, has been found to present a range of interesting biological properties. This study aimed to evaluate the anti-hypersensitive and anti-inflammatory effects of isocordoin (1) and several natural and semisynthetic derivatives (2–10). Initial evaluation of (1), dihydroisocordoin (2) and six semisynthetic derivatives (3–8) in the inhibition of abdominal writhes induced by acetic acid
Isocordoin (1) 是一种从不同植物中分离出来的查耳酮,已被发现具有一系列有趣的生物学特性。本研究旨在评估异考多因 (1) 和几种天然和半合成衍生物 (2-10) 的抗过敏和抗炎作用。对 (1)、二氢异香豆素 (2) 和六种半合成衍生物 (3-8) 抑制醋酸模型引起的腹部扭动的初步评估表明,只有异香豆素二甲醚 (5) 引起超过 70% 的抑制。对 5 的抗水肿活性和抗过敏作用的进一步评估由角叉菜胶、脂多糖 (LPS)、缓激肽 (BK)、前列腺素 E2 (PGE2) 和肾上腺素引起,结果表明异科尔多因二甲醚 (5) 对角叉菜胶具有离散抑制作用- 和 LPS 诱导的超敏反应,和角叉菜胶引起的爪子水肿,并且它能够显着减少 BK 引起的水肿和超敏反应。此外,当在 PGE2 模型中测试时,5 只干扰爪子水肿,对爪子超敏反应没有任何影响。在 BK 诱导的水肿和超敏反应中对天然异科尔多因 (1)
