Chemical structure and the cytotoxic activity of sitravatinib in ABCG2-overexpressing cell lines and their corresponding sensitive cell lines. (A) Chemical structure of sitravatinib. The cell viability-concentration curves for NCI-H460/MX20 and NCI-H460 (B), S1-M1-80 and S1 (C), HEK293 cell lines transfected with full length ABCG2 or empty vector (D) after treatment with serial concentrations of sitravatinib for 72 h. Data are shown as mean ± SD, obtained from at least three experiments performed independently.
