There are now described some novel alpha-[1-aryl-2,2,2-trifluoroethoxy (or-ethylthio)]alkanoic acids that are useful for reducing triglycerides and cholesterol levels in the blood of animals. The percentage reduction in test rats has been observed to be from 20 to 65 for triglycerides and from 15 to 50 for cholesterol. A representative compound of the invention is alpha-(2,2,2-trifluoro-1-phenyl-1-ethoxy)butyric acid. Most of the compounds have an LD.sub.50 greater than 800 mg/kg, intraperitoneally, in male mice. A method of use, compositions, and a process for synthesis are also described.
现在描述了一些新颖的α-[1-芳基-2,2,2-三氟乙氧基(或-乙硫基)]脂肪酸,可用于降低动物血液中的甘油三酯和胆固醇水平。测试大鼠中观察到的甘油三酯降低百分比为20至65,胆固醇降低百分比为15至50。该发明的代表性化合物是α-(2,2,2-三氟-1-苯基-1-乙氧基)丁酸。大多数化合物在雄性小鼠腹腔内的LD.sub.50大于800毫克/千克。还描述了一种使用方法、组合物和合成过程。
