ethanol-loaded rat, various sesquiterpenes having an alpha-methylene-gamma-butyrolactone moiety, costunolide (1), dehydrocostus lactone (2), zaluzanin D (3), reynosin (4), santamarine (5), 3alpha-acetoxyeudesma-1,4(15),11(13)-trien-12,6alpha-+ ++olide (6) and 3-oxoeudesma-1,4,11(13)-trien-12,6alpha-olide (7), were isolated as the active principle from the leaves of Laurus nobilis (bay leaf, laurel). In
通过在抑制口服乙醇的大鼠血液乙醇升高方面具有抑制活性的生物测定指导分离,各种倍半萜具有α-亚甲基-γ-丁内酯部分,木香酚内酯(1),脱氢古斯内酯(2),扎鲁赞宁D(3),肌球蛋白(4),三mar(5),3alpha-acetoxyeudesma-1,4(15),11(13)-trien-12,6alpha- + ++ olide(6)和3-oxoeudesma-1,4,11(从月桂叶(月桂叶,月桂树)的叶子中分离出作为活性成分的13)-trien-12,6α-内酯(7)。为了表征活性的结构要求,由2合成了几种还原产物(2a-2d)和α-亚甲基-γ-丁内酯部分的氨基酸加合物(2e,2f),并且这些倍半萜烯具有抑制活性,连同α-亚甲基-γ-丁内酯(12)及其相关化合物(13-16),被检查。这些结果表明,具有α-亚甲基或α-甲基的γ-丁内酯或γ-丁内酯部分对于抑制乙醇吸收是必不可少的。由于1、
