Title: Hua Bai and a Potentially Scalable Route to Tetrodotoxin

Introduction

Hua Bai is an inventor associated with Shanghai, China. His work includes a patent describing a biological and chemical synthesis method for tetrodotoxin, a compound traditionally obtained through extraction from pufferfish.

Latest Patents

Bai is associated with 1 patent: “Method for Large-Scale Synthesis of Tetrodotoxin.” The invention begins with benzyl acetate, an inexpensive and readily available raw material, and uses biological fermentation to produce an optically pure intermediate, ((5S, 6R)-5, 6-dihydroxycyclohexa-1, 3-dienyl) methyl acetate. A series of chemical conversions then yields tetrodotoxin with a reported purity of at least 95%, without purifying the product. The method is presented as having potential for large-scale production and as an alternative to extraction from pufferfish.
