体外活性
Human mammary carcinoma MCF-7 cell line responsiveness to the pteridines xanthopterin and isoxanthopterin was studied using the MTS assay for measurement of cell viability. The pteridines were tested at concentrations ranging from 7.8 to 500 μM singly and in 11 isoxanthopterin:xanthopterin ratios. IC50s of xanthopterin and isoxanthopterin were 109±13 μM (mean±SEM of y estimate) and 103±9 μM, respectively.
