Latest Patents

One of Okuro's latest patents is for a type I natural ceramide derivative and the method for producing it. This invention aims to provide a novel type I natural ceramide derivative that closely resembles the structure of a type I natural ceramide composed of sphingosine and an ω-acyloxy long-chain carboxylic acid. The method involves reacting an ω-acyloxy long-chain fatty acid derivative with dihydrosphingosine or a salt thereof. The resulting ceramide derivative enhances the compatibility of ceramides when combined with other ceramides, facilitating the preparation of compositions such as moisturizers or cosmetics, while also improving their storage stability.

Another significant patent is for an imidazolidinone derivative, which includes a method for producing the same and a method for synthesizing optically active amino acids. This invention provides a novel optically active imidazolidinone derivative that can be used for synthesizing optically active amino acids. The method allows for the easy production of the derivative through preferential crystallization from a mixture of isomers, enabling the stereoselective production of optically active amino acids without the cumbersome procedures typically required by conventional methods.
