Claim:
A compound of formula (I): wherein A is a cyclic moiety selected from the group consisting of C 3-14 cycloalkyl, 3-14 membered heterocycloalkyl, C 4-14 cycloalkenyl, 3-14 membered heterocycloalkenyl, aryl, heteroaryl; the cyclic moiety being optionally substituted with 1-3 substituents, each of which is independently selected from the group consisting of alkyl, alkenyl, alkynyl, alkoxy, hydroxyl, hydroxylalkyl, halo, haloalkyl, amino, alkylcarbonyloxy, alkyloxycarbonyl, alkylcarbonyl, alkylsulfonylamino, aminosulfonyl, and alkylsulfonyl; each of X 1 and X 2 , independently, is O or S; Y 1 is —CH 2 —, —O—, —S—, —N(R a )—, —N(R a )—C(O)—O—, —O—C(O)—N(R a )—, —N(R a )—C(O)N(R b )—, —O—C(O)—O—, or a bond; each of R a and R b , independently being hydrogen, alkyl, alkenyl, alkynyl, alkoxy, hydroxylalkyl, hydroxyl, or haloalkyl; Y 2 is CH 2 ; L is an unsaturated C 4-8 hydrocarbon chain containing at least one double bond; said unsaturated-hydrocarbon chain being substituted with C 3-5 cycloalkyl, 3-5 membered heterocycloalkyl, monocyclic aryl, 5-6 membered heteroaryl, C 1-4 alkylcarbonyloxy, C 1-4 alkylcarbonyl, or formyl, —NH 2 , —NH(C 1-2 alkyl), or —N(C 1-2 alkyl) 2 , or —N(C 1-2 alkyl) 2 ; provided that when L contains two or more double bonds, the double bonds are not adjacent to each other; or a salt thereof, wherein the compound is not 8-phenyl-5-octenoic acid, 6-phenyl-5-hexenoic acid, 5,5-diphenylpent-4-enoic acid, 2,2-dichloro-12-phenyl-11-dodecenoic acid, 8-phenyl-6-octenoic acid or 13-phenyl-11-triedecenoic acid.
