Abstract [en]

The invention relates to benzoic acid derivs. of formula I, which are inhibitors of glycine receptors (GlyRs). In compds. I, Y is H, OH, halo, (un)substituted C1-6 alkoxy, or (un)substituted C1-6 alkyl; R1 is (un)substituted C3-6 cycloalkyl, (un)substituted heterocyclyl, (un)substituted aryl, (un)substituted alkylaryl, (un)substituted heteroaryl, or (un)substituted C3-6 alkyl; L is selected from a bond, heteroarylene, -C(O)-, -CH2-, -CH(OR4)-, -N(OH)-, -N(R4)-, -S(O)n-, where R4 is H or C1-6 alkyl and n is 0, 1, or 2; R2 is H, halo, cyano, dimethylamino, (un)substituted C1-6 alkyl, (un)substituted C3-6 cycloalkyl, (un)substituted heterocyclyl, (un)substituted aryl, (un)substituted alkylaryl, (un)substituted heterocyclyl or (un)substituted heteroaryl; and R3 is OH or C1-6 alkoxy; with the exclusion of several compds. The invention also relates to the prepn. of I, pharmaceutical compns. comprising a therapeutically effective amt. of a compd. I with one or more pharmaceutically acceptable diluents, excipients and/or inert carriers, as well as to the use of the compns. for the treatment of conditions that respond to glycine receptor inhibition, such as neuropathic or inflammatory pain syndromes. Chlorination of 4-methoxybenzenethiol followed by C-substitution with 3-tert-butyl-2-hydroxy-6-methylbenzoic acid and oxidn. gave (arylsulfonyl)benzoic acid II. Several compds. of the invention expressed IC50 values against human GlyR α1 of about 10 nM to about 30 μM (no specific data). [on SciFinder(R)]
