A selective PI3K inhibitor
Copanlisib is an inhibitor of class I phosphoinositide 3-kinase (PI3K) isoforms (IC50s = 0.5, 3.7, 6.4, and 0.7 nM for α, β, γ, and δ, respectively).1 It is weakly active or inactive against numerous other kinases. Copanlisib is effective in vivo when administered intravenously, inhibiting PI3K signaling and inducing tumor regression via apoptosis in xenograft tumors in mice.1,2
