Background/Aim: The prognosis of ovarian cancer (OC) patients is especially poor for patients with chemotherapy resistance. Anlotinib, a novel multi-targeted tyrosine kinase inhibitor, has shown encouraging clinical efficacy in several tumor types. The aim of the present study was to examine the inhibitory efficacy and mechanism of anlotinib on the proliferation and chemosensitivity of OC cells. Materials and Methods: The inhibitory effects of Anlotinib on SKOV3 and OVCAR3 OC cells were examined using CCK-8 cell-viability, colony-formation, flow-cytometry, transwell-migration and sphere-formation assays. A xenograft mouse model was used for in vivo studies. RT-qPCR and western blotting were used to detect gene expression. Results: Molecular targets of anlotinib were elevated in OC patient tumors. Anlotinib significantly inhibited ovarian cancer cell proliferation and migration in vitro. Anlotinib enhanced the sensitivity of ovarian cancer cells to cisplatinum both in vitro and in vivo. Anlotinib suppressed sphere formation and the stemness phenotype of OC cells by inhibiting NOTCH2 expression. Conclusion: Anlotinib inhibits ovarian cancer and enhances cisplatinum sensitivity, suggesting its future clinical promise.
