Axl-IN-21

Axl-IN-21 is an orally active and selective AXL inhibitor (Kd = 2.7 nM, IC50 = 4.0 nM) . Axl-IN-21 displays kinase selectivity and retains strong activity against cancer-related mul-kinases (Mer with Kd = 1.4 nM, DDR1 with IC50 = 22.2 nM, HIPK4 with Kd = 11.0 nM and LOK with Kd =10 nM) . Axl-IN-21 overcomes tumor microenvironment-driven resistance by blocking CAF-derived GAS6-induced AXL/STAT3/ABCG1 signaling, restoring chemosensitivity and inhibiting drug efflux in gastric cancer (GC) . Axl-IN-21 suppresses TGF-β1-induced epithelial-mesenchymal transition (EMT), migration, and invasion in MDA-MB-231 cells. Axl-IN-21 exhibits no significant cytotoxicity in non-cancerous cells. Axl-IN-21 can be research for triple negative breast cancer and gastric cancer[1] [2] .
