series of nitroso derivatives (11–15), isoxazolopyrazoles (17a–c) and isoxazolo[3,4-d]pyridazines (18a–c) were prepared from the hydroxyimoyl chloride 10. In vitro COX1⧹2 inhibition activities were evaluated, both of 17b and 18a proved a promising inhibitory activity with IC50 = 1.12, 0.78 μM in sequent. Carrageenan induced Paw edema, ulcer liability, nitric oxide (NO) release and histopathological study
从羟基碘酰氯10制备了三个新系列的亚硝基衍生物(11 – 15),异恶唑并吡唑(17a – c)和异恶唑并[3,4- d ]哒嗪(18a – c)。评估了体外COX1⧹2抑制活性,随后17b和18a均被证明具有良好的抑制活性 ,随后的IC 50 = 1.12,0.78μM 。角叉菜胶诱发的爪水肿,溃疡病,一氧化氮(NO确定释放和组织病理学研究。大多数制备的化合物显示出优异的活性。研究了2-氨基吡啶和烯胺酮与羟基碘酰氯10的反应,并通过2D NMR进行了证明。对大多数活性化合物进行了分子对接,为化合物与受体之间的相互作用提供了提示。
