Abstract
Novel compounds which are 2,6-di-t-butylphenols substituted in the 4 position by an alkoxy or benzyloxy group or a benzylthio group, which alkoxy or benzyloxy group is directly substituted by a tetrazole ring, and which benzylthio group is directly substituted by carboxy or tetrazolyl are useful as inhibitors of leukotriene biosynthesis and as antiallergic agents.
