摘要:The invention relates to biochemical synthesis of 6-amino caproic acid from 6-aminohex-2-enoic acid compound or from 6-amino-2-hydroxyhexanoic acid, by treatment with an enzyme having α,β-enoate reductase activity towards molecules containing an α,β-enoate group and a primary amino group. The invention also relates to processes for obtaining suitable genetically engineered cells for being used in such biotransformation process, and to precursor fermentation of 6-amino caproic acid from intermediates leading to 6-amino caproic acid. Finally, the invention relates to certain novel biochemically produced compounds, namely 6-aminohex-2-enoic acid, 6-aminohexanoic acid, as well as to caprolactam produced therefrom and to nylon-6 and other derivatives produced from such biochemically produced compounds or caprolactam.

标题 :Method of using synthetic L-Se-methylselenocysteine as a nutriceutical and a method of its synthesis
发明人:SPALLHOLZ JULIAN E; REID TED W; WALKUP ROBERT D
权利人:PHARMASE INC
摘要:A synthesis of and use for L-Se-methylselenocysteine as a nutriceutical is described, based upon the knowledge that L-Se-methylselenocysteine is less toxic than L-selenomethionine towards normal cells. The synthesis proceeds by mixing N-(tert-butoxycarbonyl)-L-serine with a dialkyl diazodicarboxylate and at least one of a trialkylphosphine, triarylphosphine, and phosphite to form a first mixture that includes N-(tert-butoxycarbonyl)-L-serine β-lactone. Methyl selenol or its salt is mixed with the N-(tert-butoxycarbonyl)-L-serine β-lactone to form a second mixture that includes N-(tert-butoxycarbonyl)-Se-methylselenocysteine. The tert-butoxycarbonyl group is removed from the N-(tert-butoxycarbonyl)-Se-methylselenocysteine to form L-Se-methylselenocysteine. This synthesis significantly improves the manufacturability, manufacturing efficiency, and utility of this naturally occurring rare form of organic-selenium. L-Se-methylselenocysteine formed, for example, in this manner may be used as a nutriceutical for supplementation into the diets of humans or animals for various beneficial purposes, such as, for example, to prevent or reduce the risk of developing cancer.
