Abstract

The disclosure provides methods for treating fatty liver disease and associated conditions by inhibiting the synthesis of glucosphingolipids, as exemplified by the use of glucosylceramide synthase substrate analogs.

Claims

1. A method of treating fatty liver disease in a subject in need thereof, comprising administering to the subject an effective amount of a compound of Formula I:

2. The method of claim 1, wherein R₁ is chosen from substituted and unsubstituted phenyl.

3. The method of claim 2, wherein R₁ is 1,4-benzodioxan-6-yl.

4. The method of claim 1, wherein R₂ is chosen from substituted and unsubstituted C₇-C₁₈ alkyl.

5. The method of claim 4, wherein R₂ is chosen from substituted and unsubstituted C₇ or C₈ alkyl.

6. The method of claim 5, wherein R₂ is 1-(1-hydroxyheptyl), 1-(6-hydroxyheptyl), 1-(1-hydroxyoctyl) or 1-(7-hydroxyoctyl).

7. The method of claim 1, wherein R₃ is pyrrolidine.

8. The method of claim 7, wherein R₃ is pyrrolidino, and R₂ is C₇ or C₈ alkyl.

9. The method of claim 1, wherein the compound of Formula I is

10. The method of claim 1, wherein the compound of Formula I is 1-(R)-(1,4-benzodioxan-6-yl)-2(R)-octanoylamino-3-pyrrolidino-1-propanol, or a pharmaceutically acceptable salt thereof.

11. The method of claim 1, wherein the pharmaceutically acceptable salt is tartrate.

12. The method of claim 1, further comprising administering to the subject at least one compound selected from the group consisting of an α

-glucosidase inhibitor, a biguanide, insulin, a meglitinide, a sulfonylurea, a thiazolidinedione, an antioxidant, a lipid-lowering agent, a weight-loss agent, a cytoprotective agent, an alpha-2 adrenergic agonist, an anticonvulsant, a barbiturate, a benzodiazepine, a beta-adrenergic blocker, disulfiram, an opioid antagonist, a phenothiazine, and a serotonin reuptake inhibitor.
