A method and composition for the treatment of acne vulgaris, acne rosacea, and other inflammatory skin conditions comprises the oral administration of a composition comprising a dose of nicotinamide delivered at levels substantially in excess of normal dietary levels, the nicotinamide being delivered in combination with zinc. The composition may also include quantities of copper and folic acid. In a most preferred embodiment, the nicotinamide and copper each are present in immediate release formats, while the zinc is present in a sustained release format.
A method for the treatment and prophylaxis of conditions of aging in humans, such conditions of aging associated with a decreased presence of one or more cell-specific carbonic anhydrase enzymes. Such conditions include chronic neurodegenerative conditions including dementia such as Alzheimer's disease. The method comprises administering to the patient a pharmaceutically effective, non-toxic amount of a compound that increases the presence of one or more cell-specific carbonic anhydrase enzymes whose levels are reduced in the patient. Such compound may be the cell-specific carbonic anhydrase enzyme, a compound that when absorbed by the body reacts or dissociates to form the cell-specific carbonic anhydrase enzyme, or a compound that promotes the natural generation of the cell-specific carbonic anhydrase enzyme within the body.
The present invention relates to a sequence for the preparation of amino acids, for example alpha amino acids, in particular methionine, by making use of an amidocarbonylation reaction and reuse of the catalyst.
The present invention relates to a sequence for the preparation of amino acids, for example alpha-amino acids, in particular methionine, by making use of an amidocarbonylation reaction in the presence of a cobalt carbonyl catalyst and separating the catalyst in the form of a Co(N-amino acid).sub.2 compound.
