be equipotent or less potent that of rebamipide. Pharmacological studies suggest that the presence of a methoxy group at position C-5 or C-8 of the scoparone’s phenyl ring significantly improves gastroprotective activity, whereas the presence of a dioxolane ring at C-6, C-7, or C-8 was found to have decreased activity. In order to assess toxicological safety, two of the potent gastroprotective scoparone
这项研究调查了合成的二十烷酮衍生物对实验性胃炎的胃保护作用及其毒理学安全性。合成了六种scoparone衍生物,并针对HCl /乙醇和吲哚美辛诱导的胃溃疡筛选了胃保护活性。在这些化合物中,发现5,6,7-三甲氧基香豆素和6,7,8-三甲氧基香豆素的胃保护活性大于标准药物瑞巴派特。发现6-甲氧基-7,8-亚甲基二氧基香豆素,6-甲氧基-7,8-(1-甲氧基)-亚甲基二氧基香豆素,6,7-亚甲基二氧基香豆素和6,7-(1-甲氧基)-亚甲基二氧基香豆素是等价的或瑞巴比特的药效较弱。药理研究表明,在二十烷酮苯环的C-5或C-8位上存在甲氧基可显着改善胃保护活性,而在C-6,C-7或C-8上存在二氧戊环则可改善胃保护活性。被发现活动减少。为了评估毒理学安全性,研究了两种有效的胃保护性scoparone衍生物(5,6,7-三甲氧基香豆素和6,7,8-三甲氧基香豆素)对小鼠的急性毒性以及对细胞色素P45
