The present invention relates to compositions comprising branched-chain amino acids (BCAA) and the dipeptide L-Alanyl-L-alanine and their use for improving the performance and recovery during physical activity and for the prevention and/or treatment of muscle wasting associated to pathological or age-related conditions.

A method, composition, and kit for treating a malarial infection in a subject by using an enzyme conjugate comprising a variant cystathione-gamma-lyase and a targeting ligand which binds to erythrocytes infected with Plasmodium pathogens. The variant cystathione-gamma-lyase has methioninase activity. Also disclosed is a method of treating Plasmodium-infected blood by exposing the infected blood with the enzyme conjugate.

The disclosure provides compounds having formula (I):

##STR00001##

and the pharmaceutically acceptable salts thereof, wherein R.sub.1, R.sub.2, R.sub.2′, and X are as defined as set forth in the specification, for use in treating cognitive deficits and/or psychiatric disorders, such as those associated with neurological or neurodegenerative disorders, psychiatric or mood disorders, and HIV-associated neurocognitive disorders (HAND). Compounds having formula (I) are prodrugs that release glutamine analogs, e.g., 6-diazo-5-oxo-L-norleucine (DON).

A composition and method of treatment of neuromuscular, neuromuscular degenerative, neurodegenerative, autoimmune, developmental, traumatic, hearing loss related, and/or metabolic diseases, including spinal muscular atrophy (SMA) syndrome (SMA1, SMA2, SMA3, and SMA4, also called Type I, II, III and IV), traumatic brain injury (TBI), concussion, keratoconjunctivitis sicca (Dry Eye Disease), glaucoma, Sjogren's syndrome, rheumatoid arthritis, post-LASIK surgery, anti-depressants use, Wolfram Syndrome, and Wolcott-Rallison syndrome. The composition is selected from the group consisting of 2,3-DNP, 2,4-DNP, 2,5-DNP, 2,6-DNP, 3,4-DNP, or 3,5-DNP, bipartite 2,3-dinitrophenol, 2,4-dinitrophenol, 2,5-dinitrophenol, 2,6-dinitrophenol, 3,4-dinitrophenol, or 3,5-dinitrophenol (2,3-DNP, 2,4-DNP, 2,5-DNP, 2,6-DNP, 3,4-DNP, or 3,5-DNP) prodrugs; Gemini prodrugs, bioprecursor molecules, and combinations thereof. A dose of the composition for treatment of neurodegenerative diseases may be from about 0.01 mg/kg of body weight to about 50 mg/kg of body weight of the patient in need of treatment. A dose of the composition for treatment of metabolic diseases may be from about 1 mg/70 kg of body weight to about 100 mg/70 kg of body weight of the patient in need of treatment, and a maximum dose per day is about 200 mg/70 kg of body weight of the patient in need of treatment.
