- Ethanesulfonyl-piperidine derivatives
-
The invention relates to compounds of the general formula STR1whereinR 1 signifies hydrogen or hydroxy; R 2 signifies hydrogen or methyl; and X signifies --O-- or --CH 2 -- and their pharmaceutically acceptable acid addition salts.It has been shown that these compounds have a good affitity to the NMDA receptor and they are therefore useful in the treatment of diseases, wherein the therapeutic indications include acute forms of neurodegeneration caused, e.g., by stroke or brain trauma; chronic forms of neurodegeneration such as Alzheimer''s disease, Parkinson''s disease, Huntington''s disease or ALS (amyotrophic lateral sclerosis); neurodegeneration associated with bacterial or viral infections, and, diseases such as schizophrenia, anxiety, depression and chronic/acute pain.

- Novel phenolic thioethers as inhibitors of 5-lipoxygenase
-
The compounds of the present invention comprise substituted phenolic thioethers represented by the formula: STR1 wherein: R1 and R2 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; R3 represents CO2 H, CO2 -alkyl or a tetrazole group; m is 0 or 1, n is 2, 3 or 4 and p is 1, 2 or 3; and 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.
