Latest Patents

Ichirou Ikeda's latest patents include a method for producing cytosine nucleoside compounds. This invention provides a method for producing a cytosine nucleoside compound from pentose-1-phosphate and cytosine or a derivative thereof using a nucleoside phosphorylase reactive to cytosine or a bacterium having the enzyme activity. The invention also offers a method for specifically reducing the activity to degrade the substrates or the product, resulting in efficient production of the cytosine nucleoside compound. According to the invention, little by-product is produced in the process of creating cytonucleoside compounds. Another patent involves a process for selectively producing a 1-phosphorylated sugar derivative anomer and a process for producing nucleoside. In this process, a desired isomer is selectively prepared by phosphorolyzing and isomerizing an anomer mixture of a 1-phosphorylated saccharide derivative while crystallizing one of the isomers to displace the equilibrium. Furthermore, using the action of a nucleoside phosphorylase, a nucleoside is prepared from the 1-phosphorylated saccharide derivative obtained and a base with improved stereoselectivity and a higher yield.
