Structural modification of the isocoumarin moiety (A and B rings) of 1'-benzylspiro-[isocoumarin-piperidines] (1a and 2a), which inhibit the compound 48/80-induced release of histamine from isolated rat peritoneal mast cells, was undertaken to clarify the structure-activity relationship. Chromanone (3), chroman (4), 1, 3-benzoxazine (5), 1, 3-benzothiazine (6), and 4-quinazolinone (7) analogs were active, although there were differences in potency. Substituent effects on the benzene moiety (A ring) of 3 were examined.
1'-苄基螺-[异香豆素-哌啶](1a 和 2a)的异香豆素分子(A 环和 B 环)可抑制化合物 48/80 诱导的离体大鼠腹膜肥大细胞释放组胺,为明确其结构-活性关系,对其进行了结构改造。色满酮(3)、色满(4)、1,3-苯并恶嗪(5)、1,3-苯并噻嗪(6)和 4-喹唑啉酮(7)类似物均具有活性,但效力存在差异。对 3 的苯分子(A 环)的取代作用进行了研究。
