  • Publication number: 20230312596
    Abstract: The present invention provides a method for biological and chemical synthesis of tetrodotoxin, specifically comprising the following steps: using cheap and easily available benzyl acetate as a raw material, and performing biological fermentation to obtain an optically pure intermediate ((5S, 6R)-5, 6-dihydroxycyclohexa-1, 3-dienyl) methyl acetate (formula I); and performing a series of chemical conversions on the intermediate to finally obtain tetrodotoxin at a purity of 95% or more without purifying the product. The present invention has the potential of large-scale production, and is an excellent alternative to the existing extraction method from a pufferfish.
