  • Alpha-amylase inhibitors: the montbretins and uses thereof
    Patent number: 8431541
    Abstract: Particular naturally occurring glycosylated acyl-flavonols are now shown to be effective mammalian ?-amylase inhibitors. Such compounds can be obtained from plants of the genus Crocosmia and the compounds are useful in controlling starch digestion such as for management of glycemia in pre-diabetic or diabetic subjects, for management of obesity or for inhibiting oral caries or plaque formation.

  • Myoglobin with peroxidase activity
    Patent number: 5854041
    Abstract: Myoglobin is shown to have Manganese (Mn.sup.2') binding and peroxidase capacity. Mn binding and peroxidase activity is enhanced by modification of the amino acid sequence of myoglobin to provide a Mn binding site on the surface of the protein near the heme group. Peroxidase activity of myoglobin not specific to Mn is enhanced by substituting amino acids at residues 39, 45, 46, 97 and 107 of myolglobin.
