LDC1267 blocks GAS6-induced AXL phosphorylation and the downstream AKT/ERK1/2 signaling pathway. 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.

UNC569 also inhibits Axl and Tyro3 with IC₅₀s of 37 nM and 48 nM, respectively. UNC569 can be used for acute lymphoblastic leukemia (ALL) and atypical teratoid/rhabdoid tumors research

UNC5293 is a MERTK-selective and potent inhibitor (K_i=190 pM). UNC5293 inhibits MERTK (IC₅₀=0.9 nM) and is more selective over Axl, Tyro3 and Flt3. UNC5293 exhibits excellent mouse PK properties and is used for bone marrow leukemia research.

Gilteritinib (ASP2215) hemifumarate is a potent and ATP-competitive FLT3/AXL inhibitor with IC₅₀ of 0.29 nM/0.73 nM, respectively.

Tamnorzatinib (ONO-7475) is a potent, selective, and orally active Axl/Mer inhibitor with IC50 values of 0.7 nM and 1.0 nM, respectively. Tamnorzatinib sensitizes AXL-overexpressing EGFR-mutant NSCLC cells to the EGFR-TKIs, suppresses the emergence and maintenance of tolerant cells. Tamnorzatinib combines with Osimertinib (HY-15772) provides a bright promise for the study of EGFR-mutated non-small cell lung cancer (NSCLC).

SGI-7079 is a selective, ATP-competitive, orally active inhibitor of the receptor tyrosine kinase Axl. SGI-7079 blocks Axl-mediated signaling pathways such as NF-κB activation and MMP-9 expression, thereby inhibiting tumor cell proliferation, migration and invasion. 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. Tilvestamab significantly inhibits Gas6-induced AXL activation in 786-0-Luc RCC cells and inhibits downstream AKT phosphorylation. Tilvestamab can be used in cancer research, particularly in AXL overexpressing renal cell carcinomas.

UNC9426 reduces platelet aggregation without increasing bleeding time and blocks TYRO3-dependent functions in tumor cells and macrophages. UNC9426 demonstrates a favorable safety profile with no significant increase in bleeding risk in vivo. UNC9426 can be used for functional studies of TYRO3-dependent phenotypes such as non-small cell lung cancer (NSCLC).
