PF-04217903
CAS No. : 956905-27-4
MCE 国际站：PF-04217903
产品活性：PF-04217903 是一种高效的 ATP 竞争性 c-Met 激酶抑制剂，Ki 为 4.8 nM。PF-04217903 相对于 208 个激酶显示出 1000 倍以上的选择性。具有抗血管生成特性。
研究领域：Protein Tyrosine Kinase/RTK
作用靶点：c-Met/HGFR
In Vitro: PF-04217903 (0.1-10000 nM; 48-72 hours) inhibits proliferation of c-Met–amplified human GTL-16 gastric carcinoma and H1993 NSCLC cells with IC50 values of 12 and 30 nM, respectively.
PF-04217903 (1.5-3333 nM; 48 hours) induces apoptosis of GTL-16 cells (IC50=31 nM).
PF-04217903 also inhibits HGF-mediated cell migration and Matrigel invasion in several c-Met–overexpressing tumor cell lines such as human NCI-H441 lung carcinoma and HT29 colon carcinoma with IC50 values comparable with those for inhibition of c-Met phosphorylation in these cell lines (IC50=7-12.5 nM).PF-04217903 displays similar potency to inhibit the activity of c-Met-H1094R, c-Met-R988C, and c-Met-T1010I with IC50 of 3.1 nM, 6.4 nM, and 6.7 nM, respectively, but has no inhibitory activity against c-Met-Y1230C with IC50 of >10 μM.
In Vivo: PF-04217903 (1-30 mg/kg; p.o.; daily for 16 days) shows dose-dependent tumor growth inhibition, which correlated with the inhibition in c-Met phosphorylation in these tumors.
PF-04217903 (5-50 mg/kg, p.o.; once daily for 3 days) dose dependently inhibits c-Met, Gab-1, Erk1/2, and AKT phosphorylation and induced apoptosis (cleaved caspase-3) in U87MG xenograft tumors at all dose levels. PF-04217903 phenolsulfonate shows a significant dose-dependent reduction of human IL-8 levels in both the U87MG and GTL-16 models and decreases human VEGFA levels in the GTL-16 model. PF-04217903 strongly induces phospho-PDGFRβ levels in U87MG xenograft tumors.

文献和实验用张力计等测定。以水柱的长度（单位：厘米）表示土壤对水的吸力即基质势时，数字的幅度过大，因此 R． K． Schofield取其对数以 PF表示之。 100厘米的水柱相当于 100克 /平方厘米的压力， PF=2，永久凋萎点约相当于 15个大气压， PF=4.2。
血小板因子Ⅲ（PF3）有效性测定 【参考范围】被检者血浆与正常富含血小板血浆（PRP）及乏血小板血浆（PPP）分别反应，后者较前者凝血时间（检测器法）延长不超过5s.【影响因素】1.最好采用硅化或塑料注射器，玻璃试管等需涂硅处理或使用塑料制品。因为玻璃可以激活凝血反应。 2.较理想的抗凝剂应首选枸橼酸钠。 3.止血带不应扎得太紧，时间最好不超过5min，医学教|育网搜集整理并强调采血顺利，以防激活凝血反应。 4.PF3有效测定的准确性取决于富含
