Use of (-) (3-trihalomethylphenoxy) (4-halophenyl) acetic acid derivatives for treatment of insulin resistance, type 2 diabetes, hyperlipidemia and hyperuricemia

1. A method of lowering plasma uric acid levels and plasma glucose levels in a mammal, comprising administering to said mammal a therapeutically effective amount of a (−) stereoisomer of a compound selected from the group consisting of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate, 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid, or a pharmaceutically acceptable salt of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate or 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid; wherein the (−) stereoisomer of the compound is substantially free of the (+) stereoisomer of the compound.

2. A method of lowering plasma uric acid levels and plasma cholesterol levels in a mammal, comprising administering to said mammal a therapeutically effective amount of a (−) stereoisomer of a compound selected from the group consisting of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate, 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid, or a pharmaceutically acceptable salt of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate or 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid, wherein the (−) stereoisomer of the compound is substantially free of the (+) stereoisomer of the compound.

3. A method of lowering plasma uric acid levels and plasma triglyceride levels in a mammal, comprising administering to said mammal a therapeutically effective amount of a (−) stereoisomer of a compound selected from the group consisting of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate, 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid, a pharmaceutically acceptable salt of 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate or 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid, wherein the (−) stereoisomer of the compound is substantially free of the (+) stereoisomer of the compound.

4. The method of claim 1 , wherein the compound is 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate or a pharmaceutically acceptable salt thereof, and wherein the (−) stereoisomer of the compound is in an enantiomeric excess of greater than 98%.

6. The method of claim 3 , wherein the compound is 2-acetamidoethyl 4-chlorophenyl-(3-trifluoromethylphenoxy) acetate or a pharmaceutically acceptable salt thereof, and wherein the (−) stereoisomer of the compound is in an enantiomeric excess of greater than 98%.

7. The method of claim 1 , wherein the compound is 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid or a pharmaceutically acceptable salt thereof, and wherein the (−) stereoisomer of the compound is in an enantiomeric excess of 88% or greater.

8. The method of claim 2 , wherein the compound is 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid or a pharmaceutically acceptable salt thereof, and wherein the (−) stereoisomer of the compound is in an enantiomeric excess of 88% or greater.

9. The method of claim 3 , wherein the compound is 4-chlorophenyl-(3-trifluoromethylphenoxy) acetic acid or a pharmaceutically acceptable salt thereof, and wherein the (−) stereoisomer of the compound is in an enantiomeric excess of 88% or greater.
