Patent ID: 8759558

Claim:
A lipid compound of formula (I): wherein R 1 is chosen from a C 10 -C 22 alkenyl group having 3-6 methylene interrupted double bonds in Z configuration and a C 10 -C 22 alkynyl group having 1-6 triple bonds; R 2 and R 3 are the same or different and each are independently chosen from a hydrogen atom, a hydroxy group, an alkyl group, a halogen atom, an alkoxy group, an acyloxy group, an acyl group, an alkenyl group, an alkynyl group, an aryl group, an alkylthio group, an alkoxycarbonyl group, a carboxy group, an alkylsulfinyl group, an alkylsulfonyl group, an amino group, or an alkylamino group, provided that R 2 and R 3 are not both a hydrogen atom; or R 2 and R 3 are connected in order to form a cycloalkane; Y is chosen from sulphur, sulfoxide, and sulfone; X is a carboxylic acid or a derivative thereof, wherein the derivative is a carboxylic ester, or a carboxamide, a monoglyceride, a diglyceride, a triglyceride or a phospholipid; or a pharmaceutically acceptable salt thereof, with the proviso that the compound of formula (I) is not 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenylthio) butanoic acid.
