Abstract: The present invention relates to a novel substance, viz. the N-methyl-d-glucosamine complex of 4-methyluracil of the formula: ##SPC1##A process for producing same, and use thereof.The method for producing said substance consists in reacting 4-methyluracil with an equimolar amount of N-methyl-d-glucosamine in an aqueous medium at a temperature of from 20.degree. to 50.degree. C, followed by isolation of the desired product from the solution.The N-methyl-d-glucosamine complex of 4-methyluracil possesses a pharmacological activity and is useful in medicine as a medicated compound which is a cell-growth biostimulator increasing unspecific immunity and accelerating reparative regeneration of macroorganism tissues. The medicated compound has a high activity, sufficiently wide range of therapeutical applications, and a low toxicity.Said complex may be also useful as a growth stimulator for baking, nutrient, and other yeast.
