Various 1'-(o, m, and/or p-substituted benzyl) (5), 1'-(heterocyclic arylmethyl) (6), and 1'-acyl (7) analogs of spiro [isochroman-3, 4'-piperidin]-1-one were prepared and tested for inhibitory activity on the compound 48/80-induced release of histamine from mast cells. The biological results suggested that the activity is mainly affected by the lipophilicity rather than by the electrostatic character of the 1'-substituent. 4-Benzylspiro [cyclohexane-1, 3'-hexahydroisochroman]-1'-one (17) and 9-benzyl-1-oxaspiro [5.5] undecan-2-one (18) were prepared and found to be inactive, implying that the benzene moiety in the isochroman ring is essential for the activity.
制备了多种 1'-(邻、间和/或对取代的苄基)(5)、1'-(杂环芳甲基)(6) 和 1'-酰基 (7) 的螺[异苯并吡喃-3, 4'-哌啶]-1-酮类似物,并测试了这些类似物对化合物 48/80 诱导的肥大细胞释放组胺的抑制活性。生物学结果表明,其活性主要受亲脂性而非 1'- 取代基的静电特性的影响。制备了 4-苄螺[环己烷-1,3'-六氢异苯并吡喃]-1'-酮(17)和 9-苄基-1-氧杂螺[5.5]十一烷-2-酮(18),发现它们没有活性,这意味着异苯并吡喃环中的苯分子对活性至关重要。
