3‐dihydro‐1H‐pyrrolizines with functional groups at position 5 of the heterocyclic moiety were synthesized and tested. To determine their antiinflammatory activity bovine blood was used as enzyme source for the cyclooxygenase and 5‐lipoxygenase, respectively. The iminoxy acetic acid derivative and the iminotetrazole selectively inhibit the 5‐lipoxygenase, all the other compounds show medium or low affinity to the active
合成并测试了在杂环部分的 5 位具有官能团的 6-(4-氯苯基)-7-苯基-2,3-二氢-1H-吡咯嗪。为了确定它们的抗炎活性,分别使用牛血作为环氧合酶和 5-脂氧合酶的酶源。亚氨基乙酸衍生物和亚氨基四唑选择性抑制5-脂氧合酶,其他化合物对环加氧酶和5-脂氧合酶的活性位点显示中等或低亲和力。通常,所有化合物比环氧合酶更有效地抑制 5-脂加氧酶。关于 5- 脂氧合酶的抑制,发现的最活跃的化合物与相应的丙酸化合物等效,但它们不是很好平衡的双重抑制剂,如羧酸衍生物所示。
