The present invention relates to novel
fatty acid analogous of the general formula (I): R1—[xi—CH2]n—COOR2 wherein R1 is: a C6-C24
alkene with one or more double bonds and / or with one or more triple bonds, and / or a C6-C24
alkyne, and / or a C6-C24
alkyl substituted in one or several positions with one or more compounds selected from the group comprising
fluoride,
chloride, hydroxy, C1-C4 alkoxy, C1-C4 alkylthio, C2-C5 acyloxy or C1-C4
alkyl, and wherein R2 represents
hydrogen or C1-C4
alkyl, and wherein n is an integer from 1 to 12, and wherein i is an odd number and indicates the position relative to COOR2, and wherein Xi independent of each other are selected from the group comprising O, S, SO, SO2, Se and CH2, and with the proviso that at least one of the Xi is not CH2, and with the proviso that if R1 is an alkye, then the carbon-carbon
triple bond is positioned between the (ω-1) carbon and the (ω-2) carbon, or between the (ω-2) carbon and the (ω-3) carbon, or between the (ω-3) carbon and the (ω-4) carbon, a salt,
prodrug or complex thereof, which can be used for the treatment and / or prevention of
syndrome X,
obesity, hypertension,
fatty liver, diabetes, hyperglycaemia,
hyperinsulinemia and
stenosis. Further, the invention relates to a
nutritional composition comprising said
fatty acid analogues, and a method for reducing the total weight, or the amount of
adipose tissue in an animal.
