Preparations containing creatine and imino sugars
View Patent ↗Compounds produced by combining imino sugars and creatine are herein disclosed. The compounds being in the form of a creatine imino sugar amides and produced by the disclosed methods; protecting the guanidine group of creatine and then activating the protected creatine with DCC and reacting it with an imino sugar, followed by removal of the guanidine protecting groups. The resulting creatine imino sugar amides have enhanced stability in solution as compared to related esters. In addition, specific benefits are conferred by the imino sugar in addition to, and separate from, the creatine substituent. Methods of preparation and use of these compounds are also disclosed.
