wherein L is CH 2 -O, CH 2 -S, CH 2 -CH 2 , or CH=CH; R 1 and R 2 are independently selected out of H, halogen, C1 to C3 alkyl, halogenated C1 to C3 alkyl, C1 to C3 alkyloxy, or halogenated C1 to C3 alkyloxy; Ar is an aryl moiety, preferably phenyl or naphthyl, or a moncyclic- or bicyclic heteroaryl moiety, wherein optionally the aryl or heteroaryl moiety is further substituted; X is O, S, or NR 3 , wherein R 3 is H, C1 to C3 alkyl, halogenated C1 to C3 alkyl, or tert -butyloxycarbonyl; Y is O, S, NR 4 or N(R 4 )R 5 , wherein R 4 and R 5 are independently selected out of H or C1 to C3 alkyl; and wherein if Y is O, S, or NR 4 , then both A are NH, and the punctuated bonds represent a double bond to Y and single bonds to each A; or wherein if Y is N(R 4 )R 5 , then one A is N, the other A is NH, and the punctuated bonds represent a double bond to the A being N, a single bond to the A being NH and a single bond to Y; and use of such a compound in treatment or prevention of an inflammatory disease or an inflammation-related disorder.
