    Product Description

    Galeterone is a CYP17 inhibitor (IC50 = 300 nM) that has been shown to competitively block synthetic androgen binding (EC50 = 845 nM) and to antagonize the androgen receptor in transcriptional activation assays.1 Galeterone can inhibit the growth of castration-resistant prostate cancer cells with an IC50 value of 2.9 µM and demonstrates synergy with everolimus (Item No. 11597) or gefitinib (Item No. 13166) for growth inhibition.1,2
