Copanlisib (BAY 80-6946; 20-200 nM; 24 hours; BT20 breast cancer cells) treatmemnt induces apoptosis in a subset of tumor cell lines that are resistant to Lapatinib and Trastuzumab[1].
Copanlisib (BAY 80-6946; 0.5-500 nM; 2 hours; ELT3 cells) shows complete inhibition of PI3K-mediated AKT phosphorylation in ELT3 cells[1].
Copanlisib potently inhibits cell proliferation in a panel of human tumor cell lines. Copanlisib has mean IC50 values of 19 nM against cell lines with PIK3CA-activating mutations and 17 nM against HER2-positive cell lines, whereas the activity in PIK3CA wild-type and HER2-negative cells is about 40-fold less potent[1].
