Sitravatinib inhibits ABCG2-mediated mitoxantrone transport. The accumulation of tritium-labeled mitoxantrone in NCI-H460 and NCI-H460/MX20 (A), S1 and S1-M1-80 (B). The ABCG2-mediated efflux activity in NCI-H460 (C), S1 (E) and their corresponding mitoxantrone-selected cell line NCI-H460/MX20 (D), S1-M1-80 (F) at a series of time points (0, 30, 60, 120 min). Data from at least three independent experiments are shown as mean ± SD. *p < 0.05 compared with control group.
