生物活性
SKLB4771 is a potent and selective Flt3 inhibitor with an IC50 value of 10 nM. SKLB4771 downregulates the phosphorylation of FLT3/STAT5/ERK, blocks cell proliferation, and induces apoptosis in tumor tissue[1][2].
体外研究
(In Vitro)
SKLB4771 (compound 20c) (72 h) inhibits FLT3-ITD-expressing MV4-11 cells with an IC50 value of 6 nM, and inhibits other cancer cells with IC50s of 3.05 μM (Jurkat), 6.25 μM (Ramos), 3.72 μM (PC-9), 6.94 μM (H292), and 8.91 μM (A431), respectively[1].
SKLB4771 (0-300 nM; 20 h) inhibits FLT3 phosphorylation and also decreases the phosphorylation of the downstream signaling proteins STAT5 and ERK1/2 at concentrations >0.1 μM[1].
体内研究
(In Vivo)
SKLB4771 (20-100 mg/kg; i.p.; once daily; 21 d) inhibits tumor growth in vivo without significant weight loss or any other obvious signs of toxicity on mice[1].
