Abstract

Abstract Novel compounds which are 2,6-di-t-butylphenols substituted in the 4 position by a carbamyl or acylamino group, which carbamyl or acylamino group is substituted by a group which includes an acidic substituent are useful as inhibitors of leukotriene biosynthesis and as antiallergic agents. Pharmacological methods for using such compounds and synthetic intermediates for preparing such compounds are also disclosed.
