PI-3065 is a potent inhibitor of PI3K p110δ, with IC₅₀ and K_i values of 5 nM and 1.5 nM, and exhibits less potent activity against p110α, p110β, p110γ with IC₅₀s of 910, 600, >10000 nM.

PI-3065 exhibits no inhibition of the growth of 4T1 cells, which do not express detectable levels of p110δ^[1].

Female WT BALB/c mice are orthotopically inoculated in the mammary fat pad on day 0 with 1×10⁵ 4T1 cells. Drug (75 mg/kg PI-3065, once daily) or vehicle (0.5% methylcellulose with 0.2% Tween 80) is administered by oral gavage from day -1 (administered 12 h prior to tumour cell inoculation). Tumour growth is monitored weekly by caliper measurement or by measuring luminescence using a Xenogen imaging platform. On day 35, mice are euthanized, tumours and peripheral organs extracted for in vitro luminescence measurement, followed by fixation in 4% PFA and H&E staining. KPC mice are allowed to develop advanced lesions of 5-10 mm (determined by ultrasound imaging) before treatment with vehicle or PI-3065 for a total of 14 days.
