PHA-665752
CAS No. : 477575-56-7
MCE 国际站:PHA-665752
产品活性:PHA-665752 是一种选择性的 ATP 竞争活性位点 c-Met 激酶抑制剂,Ki 为 4 nM,IC50为 9 nM。PHA-665752 对 c-Met 的选择性比一组不同的酪氨酸和丝氨酸苏氨酸激酶高 50 倍。PHA-665752 诱导细胞凋亡和细胞周期阻滞,具有细胞还原性抗肿瘤活性。
研究领域:Protein Tyrosine Kinase/RTK | Autophagy | Apoptosis
作用靶点:c-Met/HGFR | Autophagy | Apoptosis
In Vitro: PHA-665752 is a potent and ATP-competitive inhibitor of c-Met kinase activity with a Ki of 4 nM and an IC50 of 9 nM.
PHA-665752 exhibits >50-fold selectivity for c-Met enzyme compared with the majority of kinases evaluated.
PHA-665752 shows potent inhibition of c-Met RTK autophosphorylation in NIH3T3 cells engineered to express high levels of c-Met and hepatocyte growth factor (HGF).
PHA-665752 inhibits HGF-stimulated or constitutive phosphorylation of mediators of downstream of c-Met such as Gab-1, ERK, Akt, STAT3, PLC-γ, and FAK in multiple tumor cell lines.
PHA-665752 (0-1.25 μM; 18 hours) potently inhibits HGF and c-Met-driven phenotypes such as cell growth (proliferation and survival), cell motility, invasion, and/or morphology of a variety of tumor cells.
PHA-665752 (0-1.25 μM; 72 hours) induces apoptosis in both the presence and absence of HGF at concentrations that inhibited tyrosine phosphorylation of c-Met in GTL-16 cells.
PHA-665752 (0.0125-0.2 μM; 4 hours) potent inhibits HGF-induced c-Met phosphorylation in A549 cells.
In Vivo: PHA-665752 (7.5-30 mg/kg/day; i.v. ; for 9 days) exhibits statistically significant dose-dependent tumor growth inhibition of 68%, 39%, and 20% of vehicle control at the 30 mg/kg/day, 15 mg/kg/day, and 7.5 mg/kg/day doses, respectively.
PHA-665752 shows a potent cytoreductive activity in a gastric carcinoma xenograft model.

文献和实验高压灭菌,使用前需经灭菌0.22μm孔径滤膜滤过处理。 三、血清 培养中常使用小牛血清(或胎牛血清)。血清亦不能高压灭菌,无菌的小牛血清需在56℃水浴30分钟灭活补体,置4℃冰箱存放待用。配制时含量视培养细胞种类、时间而定,一般用10—15%。由于血清成分复杂、条件不易控制,可选用无血清培养基。 四、抗菌素 为防止培养时期细菌的污染,可在培养基中添加适当抗菌素,一般用量与组织 细胞培养 相同:卡那霉素100单位
血清)。血清亦不能高压灭菌,无菌的小牛血清需在56℃水浴30分钟灭活补体,置4℃冰箱存放待用。配制时含量视培养细胞种类、时间而定,一般用10-15%。由于血清成分复杂、条件不易控制,可选用无血清培养基。四、抗菌素为防止培养时期细菌的污染,可在培养基中添加适当抗菌素,一般用量与组织细胞培养相同:卡那霉素100单位/毫升,或双抗--青霉素100单位/毫升,链霉素100微克/毫升。非增殖期的细胞不能制备染色体,如人外周血淋巴细胞,但在离体培养过程中,在PHA的作用下,可被刺激转化为淋巴母细胞而进入有丝分裂
过程 1. 常规外周血培养54~56小时。 2. 同步化:同步化的药物可用氨甲蝶呤或胸腺嘧啶核苷。如用氨甲蝶呤,则加入上述已培养过的外周血中,使其最终浓度为10~7 M;如用胸腺嘧啶核苷则加入已培养过的外周血中,使其最终浓度达0.3 mg/ml。同步化需在加上述药物后再置于37℃中继续培养17小时。 3. 无菌(pH=7.0)Hank液在无菌室中洗去培养物中的残余药物。其方法是将同步化培养后的培养物在无菌室中先置于无菌离心管中用1000转/分,离心10分钟,吸去上清液培养液,加入无菌
