G-749 是一种高效的, ATP 竞争性的FLT3抑制剂,对野生型 FLT3 和突变型 FLT3-D835Y 作用的IC50值分别为 0.4 nM 和 0.6 nM。G-749 可用于急性髓系白血病 (AML) 的耐药研究。
生物活性 | G-749 is a potent, oral active and ATP competitiveFLT3inhibitor, withIC50s of 0.4 nM and 0.6 nM forFLT3wild type and FLT3-D835Y, respectively. G-749 can be used for the research of drug resistance for acute myeloid leukemia (AML)[1]. |
IC50& Target | IC50: 0.4 nM (FLT3-WT), 0.6 nM (FLT3-D835Y)[1] |
体外研究 (In Vitro) | G-749 shows potent and sustained inhibition of the FLT3 wild type and mutants including FLT3-ITD, FLT3-D835Y, FLT3-ITD/N676D, and FLT3-ITD/F691L in cellular assays[1]. G-749 inhibits autophosphorylation of FLT3 with an IC50value of ≤8 nM in FLT3-WT bearing RS4-11 and in FLT3-ITD harboring MV4-11 and Molm-14 cells[1]. G-749 (0.0001-10 nM; 72 hours) shows strong antiproliferation of leukemia cells addicted to FLT3-ITD (MV4-11 and Molm-14) in a dose-dependent manner[1]. G-749 (25-100 nM; 36 hours) causes antiproliferative activity through apoptosis[1]. G-749 (1.6-1000 nM; 2 hours) shows more potent inhibition of p-FLT3, p-ERK1/2, and p-AKT than AC220 and PKC412[1].
Cell Proliferation Assay[1] Cell Line: | MV4-11 cells, Molm-14 cells, K562 cells, HEL cells, RS4-11 cells | Concentration: | 0.0001-10 nM | Incubation Time: | 72 hours | Result: | Had antiproliferative activity for leukemia cells addicted to FLT3-ITD. |
Apoptosis Analysis[1] Cell Line: | MV4-11 cells | Concentration: | 25 nM, 50 nM, 100 nM | Incubation Time: | 36 hours | Result: | Increased apoptosis of MV4-11 cells in a dose-dependent manner. |
Western Blot Analysis[1] Cell Line: | Molm-14 cells | Concentration: | 1.6 nM, 80 nM, 40 nM, 200 nM, 1000 nM | Incubation Time: | 2 hours | Result: | Inhibited the phosphorylation of downstream effectors in the FLT3 signaling pathway, such as p-STAT5, p-AKT, p-ERK1/2, and p-FoxO3a. |
