In vivo anticancer effect of KBJK557 in tumor xenograft mice models. KBJK557 treatment (15 mg/kg body weight/100 μL per 1 week) of A549 tumor-bearing mice. A Treatment schedule for the A549 cells xenograft tumors model treated with vehicle solution and KBJK557. B The change of tumor volume was measured every 3–4 days. (n = 4) **P < 0.01. C Tumors picture for size. D Tumor weight of all mice in each group. *P < 0.05. E The change of body weight of all mice was measured every 3–4 days
