AZ14145845 reduces the phagocytosis of photoreceptor outer segments by polarized human retinal epithelial cells. AZ14145845 inhibits tumor growth and induces tumor regression in vivo, and its combination with anti-PD1 antibody and ionizing radiation improves the survival rate of mice with colorectal cancer. AZ14145845 causes retinal degeneration in mice, with pathological changes similar to those in MERTK loss-of-function models. AZ14145845 can be used in studies related to retinal degeneration, lymphoma and colorectal cancer.

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.

SGI-7079 is mainly used in the research of malignant tumors such as inflammatory breast cancer and bladder cancer, as well as in combination with immunization (used in combination with PD-1 therapy)[1][2][3].

Tilvestamab (BGB149) is a humanized anti-AXL antibody that blocks AXL-mediated cell signaling.
