“ Biochanin A supplementation also resulted in reduced microbial urease activity with half the maximal inhibitory concentration of 320 nM and also inhibited the degradation rates of total amino acids, valine, lysine, methionine and leucine by 18%, 56%, 37%, 13%, and 12%, respectively.”
“Microbial urease activity was inhibited by Biochanin A with the IC50 of 320 nM. Biochanin A also inhibited the degradation rate of Val, Lys, Met, Leu and total amino acids, respectively.”
