Latest Patents

Maeda holds a patent for a new alpha-amylase inhibitor derived from wheat, known as WAI-53. This inhibitor is characterized by a molecular weight of 24,000, as determined by gel filtration. It exhibits a single band at an electrophoretic mobility of 0.53 on polyacrylamide gel electrophoresis, according to the Davis Disc Electrophoresis Method. The WAI-53 inhibitor produces saturation curves with human salivary alpha-amylase and human pancreatic alpha-amylase, with a ratio of the amount of WAI-53 required to produce 50% inhibition of human salivary alpha-amylase to that of human pancreatic amylase above 1:250. This alpha-amylase inhibitor is particularly useful for the quantitative analysis of alpha-amylase isozymes in body fluids. Maeda has 1 patent to his name.
