Mubritinib is a potent inhibitor of the human epidermal growth factor receptor 2 (HER2) tyrosine kinase. For inhibitory testing, HER2 was expressed in the following cell types: bladder (HT1376, UMUC3, T24), kidney (ACHN), and prostate (DU145, LNCaP, LN-REC4). IC50 values for mubritinib for the bladder cancer cell lines varied from 0.09 uM to greater than 25 uM. All of the prostate cancer cell lines studied were sensitive (IC50=0.053-4.6 uM) to mubritinib, but ACHN cells were relatively less sensitive. In the xenograft model, treatment with mubritinib for 14 days significantly inhibited growth of UMUC-3 (22.9%), ACHN (26.0%), and LN-REC4 (26.5%) when compared to control.
