Abstract

9 - Polyhydroxyalkyl - isoalloxazines are solubilized by means of an N-alkylamide of an aliphatic acid containing not more than six carbon atoms, the amide being used in liquid form. The solutions are useful therapeutically. When the amide is not itself liquid, it may be liquefied by means of water or other solvent such as glycol, propylene-glycol or butylene-glycol, or by p admixture with another solid or liquid N-alkylamide or another amide. According to the examples, (1) lactoflavin, i.e. 9-d-ribityl-6 : 7-dimethyl-isoalloxazine (vitamin B2 or G), is dissolved in a mixture of N-methylacetamide and water, a mixture in equal parts by weight of N-methyl- and ethyl-acetamides, a mixture of N-(b -hydroxyethyl)-acetamide and water, a mixture of N - (b - acetylamino - ethyl) - acetamide and water, a mixture of N-hydroxyethyl-lactic acid amide and water, a saturated aqueous solution of oxalic acid-bis-hydroxyethylamide, a mixture of N-b -hydroxyethylpropionic acid amide and water, a mixture of sarcosine anhydride and water, and a mixture of N-methylacetamide and 1 : 2 - propylene - glycol; (2) 6 : 7-dimethyl-9-l-arabityl-isoalloxazine is dissolved in a mixture of N-methylacetamide and water. Acid amides.-N - hydroxyethyl - lactic acid amide is prepared by boiling lactic acid ethyl ester with ethanolamine. N-b -hydroxy-ethyl-propionic acid amide is similarly obtained using propionic acid ethyl ester.ALSO:9 - Polyhydroxyalkyl - isoalloxazines are solubilized by means of an N-alkylamide of an aliphatic acid containing not more than six carbon atoms, the amide being used therapeutically in liquid form.
