title: Antiinflammatory 2,6-di-tert-butyl-4-(2-arylethenyl)phenols.
abstract: A series of 2,6-di-tert-butyl-4-(2-arylethenyl)phenols was prepared and examined for their ability to inhibit cyclooxygenase and 5-lipoxygenase in vitro and developing adjuvant arthritis in vivo in the rat. Structure-activity relationships are discussed. Among the best compounds is (E)-2,6-di-tert-butyl-4-[2-(3-pyridinyl)ethenyl]phenol (7d). It has an IC50 of 0.67 microM for cyclooxygenase and 2.7 microM for 5-lipoxygenase and an ED50 of 2.1 mg/kg in developing adjuvant arthritis. Additional in vivo data are reported for 7d.
