Patent ID: 7544700

Claim:
A sulfonamide according to formula I: wherein Ar 1 and Ar 2 are independently from each other aryl or heteroaryl, X is O or S; R 1 is hydrogen or a C 1 -C 6 -alkyl group, or R 1 forms a 5-6-membered saturated or unsaturated ring with Ar 1 ; n is an integer from 0 to 5; Y is piperidine substituted with —NR 3′ R 3 , wherein R 3′ and R 3 are selected from the group consisting of hydrogen, C 4 -C 18 alkyl, aryl-C 1 -C 18 -alkyl, heteroaryl-C 2 -C 18 -alkyl, C 1 -C 14 alkyl substituted with C 3 -C 12 cyclo-, bicyclo-, or tricyclo-alkyl, wherein said alkyl chains may contain 1-3 oxygen or sulfur atoms; and wherein at least one of R 3 ′ or R 3 is not hydrogen; where Y forms a bond with the sulfonyl group in formula I; wherein said sulfonamide includes its geometrical isomers, in an optically active form as enantiomers, diastereomers, as well as in the form of racemates, as well as pharmaceutically acceptable salts thereof.
