Background:

DS-1205b free base is a potent and selective inhibitor of AXL kinase, with an IC50 of 1.3 nM. DS-1205b free base also inhibits MER, MET, and TRKA, with IC50s of 63, 104, and 407 nM, respectively. DS-1205b free base can inhibit cell migration in vitro and tumor growth in vivo[1].

DS-1205b (0.3-33 μM; 2-24 h) inhibits hGAS6-induced migration in NIH3T3-AXL cells (EC50=2.7 nM)[1].DS-1205b (1-10000 μM; 2-24 h) significantly inhibits the phosphorylation of AXL in NIH3T3-AXL cells. DS-1205b decreases NIH3T3 cell proliferation but not obviously inhibits growth (GI50>10,000 nM)[1].

DS-1205b (3.1-50 mg/kg; p.o. bid for 5 d) exhibits pAXL inhibition mediated antitumor effects in mice[1].
