产品描述 | Pexidartinib (PLX-3397) is an inhibitor of CSF-1R and c-Kit (IC50=20/10 nM) with selective, ATP-competitive, and oral activity. Pexidartinib has antitumor activity and induces apoptosis. |
靶点活性 | c-Kit:10 nM, FLT3:160 nM, CSF1R:20 nM |
体外活性 | 方法:BMDM-CSF-1、BMDM-LM8 和 BMDM-NFSa 细胞用 Pexidartinib (500 nM) 处理,使用 Flow cytometry 检测细胞表型。 结果:Pexidartinib 剂量依赖性降低 BMDM-CSF-1、BMDM-LM8 和 BMDM NFSa 的中 CD45+/CD11b+/CD206+ 细胞。相对于对照细胞,在 500nM Pexidartinib 下,CD206+/CD80+ 的 MFI 在所有这些细胞中降低了 50% 以上。[1] 方法:人绒毛膜癌细胞系 Bewo 和人乳腺癌细胞 MDA-MB-231 用 Pexidartinib (0-200 µM) 处理 96 h,使用 MTS assay 检测细胞活性。 结果:Pexidartinib 剂量依赖性抑制 Bewo 和 MDA-MB-231 细胞活性,IC50 分别为 5.64 µM 和 185.48 µM。[2] |
体内活性 | 方法:为对脂肪组织巨噬细胞水平的影响,将 Pexidartinib (50 mg/kg,5% DMSO and 25% PEG300 in ddH2O) 灌胃给药给喂食高脂肪饮食的 C57BL/6 小鼠,每两天一次,持续三周。 结果:Pexidartinib 治疗显著减少了进食和高脂肪饮食喂养小鼠脂肪组织中的巨噬细胞数量,而不影响总髓细胞水平。Pexidartinib 并没有极大地改变葡萄糖稳态,不影响高脂饮食诱导的内脏脂肪细胞因子表达 (IL-6 和Tnfa) 的增加,并且对应激激酶 JNK 和 ERK 的磷酸化以及巨噬细胞极化的影响有限。[3] |
激酶实验 | Competitive binding fluorescent polarization assay: Recombinant Hsp90β, TAMRA-radicicol, or various concentrations of NVP-BEP800 is added in assay buffer (50 mM TRIS pH 7.4, 5 mM MgCl2, 150 mM KCl, and 0.1% CHAPS), mixed, and incubated at room temperature for 30 to 45 minutes prior to reading. The 2D-FIDA-based HTS assay based on confocal technologies monitors the decreased fluorescence polarization on displacement of the high affinity ligand TAMRA-radicicol from Hsp90β by NVP-BEP800. The concentration of NVP-BEP800 which inhibits Hsp90β by 50% is determined from the competition curve. |
