Deltonin inhibits ERK1/2 and AKT activation. Deltonin (0.5-8 μM) significantly inhibits the proliferation of several colon cancer cell lines including SW480, SW620, LOVO and C26, with IC ₅₀ s of 1.3, 1.29, 2.11 and 1.22 μM. Deltonin also causes G2-M phase arrest and induces apoptosis in C26 cells. Deltonin (0-5 μM) decreases the phosphorylation of AKT and ERK1/2 levels in MDA‑MB‑231 cells. Deltonin (0.5-8 μM) also dose-dependently inhibits the proliferation, and causes apoptosis with ROS production in MDA‑MB‑231 cells.

Deltonin (20 and 40 mg/kg, p.o.) reduces the tumor growth of 37.7% and 56.7%, and causes a 50-day survival rate of 60% and 50%, respectively, in mice. Deltonin also inhibits tumor angiogenesis in mice.
