Abstract

The invention comprises N-butyryl-, N-benzoyl- and N-palmitoyl-glutamines and N-butyryl-, N-palmitoyl- and N-diphenylacetylasparagines. These compounds, and other N-acyl-glutamines and asparagines such as the N-formyl, N-acetyl, N-propionyl, N-valeryl, N-isobutyryl, N-phenylacetyl, N-trimethylacetyl, N-stearoyl and N-sulphonyl compounds, may be prepared by reacting glutamine or asparagine with an acylating agent such as an acyl halide or acid anhydride, conveniently in a liquid reaction medium at 0 DEG C. under substantially neutral conditions, such conditions being conveniently achieved by first neutralizing the glutamine or asparagine with a base e.g. aqueous sodium hydroxide, and then adding, simultaneously, a solution of the acylating agent and a solution of a base. Salts of the N-acylated glutamines and asparagines may be prepared by conventional methods. Examples describe the preparation of the L-forms of the compounds of the invention and also the preparation of N-acetyl - L - glutamine, N - p - toluenesulphonyl-L - glutamine, N - acetyl - L - asparagine and N-phenylacetyl-L-asparagine.ALSO:An anticonvulsant composition comprises at least one compound selected from N-acyl derivatives of glutamine and of asparagine and salts of such derivatives and a solid pharmaceutical carrier, or a sterile liquid suitable for parenteral injection or an orally administrable oil. A liquid carrier may be accompanied by a solubilizer and/or dispersing agent, a liquid composition may be contained in a capsule and a solid composition may be in the form of a tablet or powder and may contain flavouring and disintegrating agents. Suitable solid carriers include corn starch, sugar, talc, and magnesium carbonate, and suitable oils include olive oil and sesame oil. Preferably the N-acyl group has 20 carbon atoms or less and is derived from a monocarboxylic acid, but it may be, for example, an N-sulphonyl group. Compositions in unit dosage form may contain from 500 mg. to 75 g. of active ingredient. A composition containing benzoyl-L-asparagine, veegum H.V., glycerine, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate and water is described.
