生物活性:
TL4830031 (compound 8i), a quinolone antibiotic derivatives, is a potent Axl inhibitor with an IC50 value of 26 nM. TL4830031 inhibits the phosphorylation of Axl. TL4830031 inhibits cell invasion and migration. TL4830031 can be used for cancer research.

体内研究:
TL4830031 (compound 8i) (0-800 mg/kg; p.o.; daily, for 7 d; ICR mice) has toxicity to liver and kidney in ICR mice.TL4830031 (2.5-50 mg/kg; p.o. and i.v.; SD rats) exhibits reasonable pharmacokinetic (PK) properties with an AUC0-∞ value of 25944.7 μg/mL·h and a T1/2 value of 5.68 h at an oral dose of 25 mg/kg. The Cmax (2386.9 μg/L=3.6 μM) occurred at 4.0 h postdose.Animal Model:ICR mice

体外研究:
TL4830031 (compound 8i) binds to Axl with a Kd value of 1.1 nM. TL4830031 exhibits a 25 fold less potency against Mer with a Kd value of 25 nM, while it is much less potent to Tyro3 with a Kd value of 750 nM.TL4830031 (0-5000 nM; 4 h; MDA-MB-231 cells) inhibits the phosphorylation of Axl (pAxl (Tyr702)) and the downstream Akt(pAkt(Thr308)) in a dose-dependent manner.TL4830031 (0-5000 nM; 4 h) reverses the expression of the EMT markers induced by TGF-β1 in MDA-MB-231 cells.TL4830031 (0-5000 nM; 24 h) suppresses migration and invasion of MDA-MB-231 cells.
