LDC1267 inhibits cancer cell proliferation, colony formation, and glioblastoma cell invasion, without causing obvious impairment of cytotoxic autophagic flux. LDC1267 exerts a synergistic effect when used in combination with Imatinib (HY-15463) in chronic myeloid leukemia models. LDC1267 can be widely applied in studies related to glioblastoma and chronic myeloid leukemia.
