Highly efficient methods for synthesis of levomethadone hydrochloride or dextromethadone hydrochloride are provided starting from D-alanine, or L-alanine, respectively, with retention of configuration. Methods for treating a subject are provided comprising administering a composition comprising an effective amount of levomethadone hydrochloride having not more than 10 ppm dextromethadone.

This document provides methods and materials for increasing the level of phosphorylated AMPK. For example, compounds (e.g., organic compounds) having the ability to increase the level of phosphorylated AMPK within cells, formulations containing compounds having the ability to increase the level of phosphorylated AMPK within cells, methods for making compounds having the ability to increase the level of phosphorylated AMPK within cells, methods for making formulations containing compounds having the ability to increase the level of phosphorylated AMPK within cells, methods for increasing the level of phosphorylated AMPK within cells, and methods for treating mammals (e.g., humans) having a condition responsive to an increase in the level of phosphorylated AMPK are provided.
