Background:

Copanlisib dihydrochloride (BAY 80-6946 dihydrochloride) is a potent, selective and ATP-competitive pan-class I PI3K inhibitor, with IC50s of 0.5 nM, 0.7 nM, 3.7 nM and 6.4 nM for PI3Kα, PI3Kδ, PI3Kβ and PI3Kγ, respectively. Copanlisib dihydrochloride has more than 2,000-fold selectivity against other lipid and protein kinases, except for mTOR. Copanlisib dihydrochloride has superior antitumor activity[1].

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) treatmemnt 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]. Apoptosis Analysis[1] Cell Line: BT20 breast cancer cells

Copanlisib (BAY 80-6946; 0.5-6 mg/kg; intravenous injection; every second day, every third day; for 60 days; athymic nude rats) treatment displays robust antitumor activity in the rat KPL4 tumor xenograft model[1]. Animal Model: Athymic nude rats injected with KPL4 tumor cells[1]
