Linifanib (ABT-869) 是一种高效、口服的VEGFR和PDGFR家族多靶点抑制剂,对 KDR、FLT1、PDGFRβ、FLT3 的IC50s 分别为 4、3、66、4 nM。Linifanib 具有显著的抗肿瘤活性。Linifanib 对无关 RTKs、可溶性酪氨酸激酶或丝氨酸/苏氨酸激酶的活性要低得多。Linifanib 是一种特异的 miR-10b 抑制剂,阻断miR-10b的生物合成。
生物活性 | Linifanib (ABT-869) is a potent and orally active multi-target inhibitor ofVEGFRandPDGFRfamily withIC50s of 4, 3, 66, and 4 nM for KDR, FLT1,PDGFRβ, andFLT3, respectively. Linifanib shows prominent antitumor activity. Linifanib has much less activity against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. Linifanib is a specific miR-10b inhibitor that blocksmiR-10bbiogenesis[1][2]. |
IC50& Target[1] | Flt-1 3 nM (IC50) | KDR 4 nM (IC50) | PDGFRβ 66 nM (IC50) | FLT3 4 nM (IC50) | CSF-1R 3 nM (IC50) | Kit 14 nM (IC50) |

体外研究 (In Vitro) | Linifanib (0-10000 nM; 72 hours) inhibits in vitro the cell proliferation of 8305C and 8505C cell lines in a concentration-dependent manner[3]. Linifanib significantly decreased the levels of phospho-CSF-1R after 24 h and 72 h in both 8505C and 8305C cells[3].
Cell Viability Assay[3] Cell Line: | 8305C and 8505C cells | Concentration: | 0-10000 nM | Incubation Time: | 72 hours | Result: | Inhibited the 8305C and 8505C cell proliferation with an IC50 of 0.7 nM and 123.7 nM, respectively. |

体内研究 (In Vivo) | The synergistic ATC antitumor activity of linifanib (10 mg/kg; p.o.; daily for 33 days)/Irinotecan combination significantly increases the survival of ATC affected mice and induces some complete responses[3].
Animal Model: | Six-week-old CD nu/nu male mice (bearing 8505C ATC cells)[3] | Dosage: | 10 mg/kg | Administration: | P.o.; daily for 33 days | Result: | The combination of linifanib and irinotecan produced a greater survival result than either monotherapy, and resulted in a significant higher median survival of 100 days. |
