The invention concerns synthesized amido-amine-based cationic gemini surfactants with flexible and rigid spacers and different hydrophobic. These gemini surfactants were prepared by modified procedure through amidation of long chain carboxylic acids using 3-(dimethylamino)-1-propylamine followed by treatment with halohydrocarbons and showed excellent thermal stability and surface properties useful for various oilfield applications such as enhanced oil recovery.

Embodiments of the invention include methods of treating, preventing, and/or reduce the risk or severity of a condition selected from the group consisting of muscle wasting, muscle weakness, cachexia, and a combination thereof in an individual in need thereof. In some embodiments, particular small molecules are employed for treatment, prevention, and/or reduction in the risk of muscle wasting. In at least particular cases, the small molecules are inhibitors of STAT3.
