Abstract
Abstract The compounds of the present invention comprise substituted phenolic thioethers represented by the formula: ##STR1## wherein: R 1 and R 2 are the same or different and independently represent tert-alkyl or phenyl; A represents methylene or methylene substituted by alkyl, dialkyl or hydroxy, provided that when A includes hydroxymethylene, the hydroxymethylene group is not adjacent to a heteroatom; B represents sulfur, sulfoxide, sulfone, oxygen, --NH-- or nitrogen substituted by alkyl, phenyl, benzyl, substituted phenyl or substituted benzyl; C represents methylene or methylene substituted by alkyl; R 3 represents CO 2 H, CO 2 -alkyl or a tetrazole group; m is 0 or 1, n is 2, 3 or 4 and p is 1, 2 or 3; amd the pharmaceutically acceptable salts thereof. The compounds of the present invention are specific inhibitors of 5-lipoxygenase and, therefore, are useful in the treatment of local and systemic inflammation, allergy and hypersensitivity reactions and other disorders in which agents formed in the 5-lipoxygenase metabolic pathway are involved.
