A series of 5-keto-substituted 7-tert-buty1-2,3-dihydro-3,3- dimethylbenzofurans (DHDMBFs) were found to be nonsteroidal antiinflammatory and analgesic agents. These compounds are inhibitors of 5-lipoxygenase (5-LOX) and cyclooxygenase (COX) with selectivity for the COX-2 isoform. A series of analogues were prepared to investigate the scope of this lead. Five ketone side chains from active DHDMBFs
发现一系列5-酮基取代的7-叔丁基1-2,3-二氢-3,3-二甲基
苯并呋喃(DH
DMBF)是非甾体类抗炎药和
镇痛药。这些化合物是5-脂氧合酶(5-LOX)和环氧合酶(COX)的
抑制剂,对COX-2同工型具有选择性。准备了一系列类似物来研究这种潜在的范围。来自活性DH
DMBF的五个酮侧链用于研究DH
DMBF“核心”变化的影响:杂环的大小和特性以及杂环和苯环的取代基要求。
生物测试表明可以适应多种结构变化,但是没有任何一种结构明显优于DH
DMBF结构。
