, and with the proviso that if R1 is an alkye, then the carbon-carbon triple bond is positioned between the (&ohgr;-1) carbon and the (&ohgr;-2) carbon, or between the (&ohgr;-2) carbon and the (&ohgr;-3) carbon, or between the (&ohgr;-3) carbon and the (&ohgr;-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.
本发明涉及一种新型脂肪酸类似物,其一般式为(I):R1—[xi—CH2]n—COOR2,其中R1是:具有一个或多个双键和/或一个或多个三键的C6-C24烯烃,和/或C6-C24炔烃,和/或在一个或多个位置上用来自氟化物、氯化物、羟基、C1-C4烷氧基、C1-C4烷基硫基、C2-C5酰氧基或C1-C4烷基的化合物组成的群体的一种或多种取代的C6-C24烷基;其中R2表示氢或C1-C4烷基,n为1到12的整数,i为奇数,表示相对于COOR2的位置,Xi独立于彼此,选自包括O、S、SO、SO2、Se和CH2的群体,但至少有一个Xi不是CH2,如果R1是炔烃,则碳-碳三键位于(ω-1)碳和(ω-2)碳之间,或者位于(ω-2)碳和(ω-3)碳之间,或者位于(ω-3)碳和(ω-4)碳之间,一种盐、前药或其复合物,可用于治疗和/或预防综合征X、肥胖、高血压、脂肪肝、糖尿病、高血糖、高胰岛素血症和狭窄。此外,本发明还涉及一种包含所述脂肪酸类似物的营养组合物,以及一种减少动物体内总体重或脂肪组织量的方法。
