    体外研究
    (In Vitro)

    Pazopanib 显示出对所有人类 VEGFR 受体的良好效力,对 VEGFR-1、-2 和-3 的 IC50 分别为 10、30 和 47 nM。还观察到对密切相关的酪氨酸受体激酶 PDGFRβ、c-Kit、FGF-R1 和 c-fms 的显著活性,IC50 分别为 84、74、140 和 146 nM。在细胞试验中,除了抑制 VEGF 诱导的 HUVEC 增殖外,Pazopanib 还有效抑制 VEGF 诱导的 HUVEC 细胞中 VEGFR-2 的磷酸化,IC50 约为 8 nM。Pazopanib 在大鼠、狗和猴子中具有良好的药代动力学,分别在 10、1 和 5 mg/kg 时具有低清除率 (1.4-1.7 mL/min/kg) 和良好的口服生物利用度 (72%、47%、65%)。除了 2C9 (7.9 μM) 外,细胞色素 P450 谱也得到改善,对测试的同工酶的抑制 >10 μM[1]

    体内研究
    (In Vivo)

    用 100 mg/kg 的 Pazopanib 处理小鼠,每天两次,持续 5 天,导致血管形成程度的显著抑制。使用 HT29 (结肠癌)、A375P (黑色素瘤) 和 HN5 (头颈癌) 肿瘤后,在携带已建立的人异种移植物 (200 250 mm3) 的小鼠中检查 Pazopanib 的抗血管生成活性标准的三周疗程。与 A375P 模型相比,HN5 和 HT29 异种移植物在所有剂量下的反应都更好,A375P 模型历来对 VEGFR-2 抑制剂具有更强的耐药性。作为支持观察到的异种移植物生长抑制是通过抗血管生成而非抗肿瘤机制发挥作用的证据,在低于 10 μM 的浓度下未观察到 Pazopanib 对这些在含血清培养基中生长的人类肿瘤细胞系 (HT29、HN5、A375P) 的抗增殖活性。未观察到对小鼠体重的显著影响,并且在整个研究期间动物看起来健康且活跃[1]
    Pazopanib 滴眼液组粘附的白细胞数量低于未处理的糖尿病动物,高于健康动物。粘附在健康动物视网膜脉管系统上的平均白细胞为 37.2±7.8,而糖尿病动物的平均值为 102±15.6,比健康动物高约 3 倍。用 0.5 % w/v Pazopanib 混悬液处理的动物在其视网膜血管系统中粘附了 69.5±9.5 个白细胞,这明显低于糖尿病动物[2]

    Kinase Assay
    [1]

    VEGFR enzyme assays for VEGGR1, VEGFR2, and VEGFR3 are run in homogeneous time-resolved fluorescence (HTRF) format in 384-well microtiter plates using a purified, baculovirus-expressed glutathione-S-transferase (GST) fusion protein encoding the catalytic c-terminus of human VEGFR receptor kinases 1, 2, or 3. Reactions are initiated by the addition of 10 μL of activated VEGFR2 kinase solution [final concentration, 1 nM enzyme in 0.1 M 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), pH 7.5, containing 0.1 mg/mL bovine serum albumin (BSA), 300 μM dithiothreitol (DTT)] to 10 μL substrate solution [final concentration, 360 nM peptide, (biotin-aminohexyl-EEEEYFELVAKKKK-NH2), 75 μM ATP, 10 μM MgCl2], and 1 μL of titrated compound in DMSO. Plates are incubated at room temperature for 60 min, and then the reaction is quenched by the addition of 20 μL of 100 mM ethylene diamine tetraacetic acid (EDTA). After quenching, 20 μL HTRF reagents (final concentration, 15 nM Streptavidin-linked allophycocyanin, 1 nM Europium-labeled antiphosphotyrosine antibody diluted in 0.1 mg/mL BSA, 0.1 M HEPES, pH 7.5) is added and the plates incubated for a minimum of 10 min. The fluorescence at 665 nM is measured with a Wallac Victor plate reader using a time delay of 50 μs[1].

    Cell Assay
    [1]

    The effect of Pazopanib on cell proliferation is measured using 5-bromo-2-deoxyuridine (BrdU) incorporation method using commercially available kits. HUVEC is seeded in medium containing 5% fetal bovine serum (FBS) in type 1 collagen coated 96-well plates and incubated overnight at 37°C, 5% CO2. The medium is aspirated from the cells, and various concentrations of Pazopanib in serum-free medium are added to each well. After 30 min, either VEGF (10 ng/mL) or bFGF (0.3 ng/mL) is added to the wells. Cells are incubated for an additional 72 h and BrdU (10 μM) is added during the last 18 to 24 h of incubation. At the end of incubation, BrdU incorporation in cells is measured by ELISA. Data are fitted with a curve described by the equation, y=Vmax(1−(x/(K+x))), where K is equal to the IC50[1].

    Animal Administration
    [1][2]

    Mice[1]
    Tumors are initiated by injection of tumor cell suspension in 8−12 week old nude mice. When tumors reach a volume of 100−200 mm3, mice are randomized and divided into groups of eight. Pazopanib is administered once or twice daily at 10, 30, or 100 mg/kg. Animals are euthanized by inhalation of CO2 at the completion of the study. Tumor volume is measured twice weekly by calipers, using the equation: tumor volume (mm3)=(length×width2)/2. Results are routinely reported as % inhibition=1−(average growth of the drug treated population/average growth of vehicle treated control population).
    Rats[2]
    Male Brown-Norway (BN; pigmented) rats weighing 200 to 250 g are acclimatized for at least two days prior to any experimental procedure. After overnight fasting for 12-16 h, an intraperitoneal injection of 30 mg/mL solution of Streptozotocin in 10 mM citrate buffer (pH 4.5) is administered (60 mg/kg body weight) to induce diabetes. After 3-4 h of Streptozotocin injection, animals are put on a regular diet and 24 h after Streptozotocin injection, blood sample (5-10 μL) is collected via tail vein. The blood glucose levels in the animals are determined with a glucose monitor. Animals with blood glucose levels greater than 250 mg/dL are considered diabetic. The animals are divided into three groups. Group 1: Healthy (n=12), Group 2: Diabetic (n=12) and Group 3: Diabetic+Treatment (n=12). Treatment is started immediately after diabetes induction. Both eyes are dosed twice daily for 30 days with 0.5 % w/v Pazopanib suspension (10 μL volume in each eye) and animals in all groups are sacrificed on day 31, 16-17 h after last dose on day 30.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
