Met受体酪氨酸激酶及其配体肝细胞生长因子(HGF)在多种人类恶性肿瘤中过表达和/或活化。血管内皮生长因子(VEGF)受体在血管内皮细胞表面表达,与Met协同诱导肿瘤侵袭和血管化。EXEL-2880(XL880,GSK1363089)是一种小分子激酶抑制剂,靶向HGF和VEGF受体酪氨酸激酶家族的成员,对KIT、Flt-3、血小板衍生生长因子受体β和Tie-2具有额外的抑制活性。EXEL-2880与Met和VEGF受体2(KDR)的结合速度非常慢,这与X射线晶体学数据一致,表明抑制剂在Met激酶活性位点裂缝中深度结合。EXEL-2880抑制细胞HGF诱导的Met磷酸化和VEGF诱导的细胞外信号调节激酶磷酸化,并防止HGF诱导肿瘤细胞的反应和HGF/VEGF诱导内皮细胞的反应。此外,EXEL-2880可防止肿瘤细胞在常氧和缺氧条件下的锚定非依赖性增殖。在体内,这些效应在肺转移的实验模型中对肿瘤负荷产生了显著的剂量依赖性抑制。总的来说,这些数据表明,EXEL-2880可能通过直接影响肿瘤细胞增殖和抑制HGF和VEGF受体介导的侵袭和血管生成来预防肿瘤生长。[1] 为了探索foretinib(GSK1363089)(一种已知靶向MET、RON、AXL和血管内皮生长因子受体(VEGFR)的口服多激酶抑制剂)在癌症中的作用机制,我们评估了该药物对以下癌症细胞系(KATO-III、MKN-1、MKN-7、MKN-45和MKN-74)中细胞生长和细胞信号传导的影响。其中,只有分别携带MET和成纤维细胞生长因子受体2(FGFR2)扩增的MKN-45和KATO-III对普罗替尼高度敏感。在MKN-45中,1μM的foretinib或PHA665752(另一种MET激酶抑制剂)如预期的那样抑制了MET和下游信号分子的磷酸化。然而,在KATO-III中,PHA665752独立于下游分子抑制MET的磷酸化。此外,1μM的foretinib或PD173074,一种选择性FGFR激酶抑制剂,抑制FGFR2和下游分子的磷酸化,表明foretinib靶向KATO-III中的FGFR2。我们在另一种FGFR2扩增的癌症细胞系OCUM-2M中证实了foretinib对FGFR2的这种新活性。使用磷酸受体酪氨酸激酶阵列,我们发现foretinib通过抑制MKN-45中的MET来抑制表皮生长因子受体(EGFR)、HER3和FGFR3的磷酸化,并通过抑制KATO-III中的FGFR2来抑制EGFR、HER2和MET的磷酸化。用siRNA敲除MKN-45的HER3和FGF R3导致细胞信号传导和细胞生长的部分抑制。总之,foretinib似乎对不仅含有MET而且含有FGFR2扩增的癌症细胞有效,并通过阻断以MET或FGFR2为核心的RTK间信号网络发挥其抑制作用[2]。 1. MKN45细胞增殖测定(MTT法):MKN45细胞以2×10³个/孔接种于96孔板,培养过夜。加入福瑞替尼(0.01 nM-10 μM),37°C孵育72小时。每孔加入MTT试剂(5 mg/mL,10 μL),继续孵育4小时。用DMSO(100 μL/孔)溶解甲瓒结晶,在570 nm处测吸光度。细胞活力以对照组的百分比表示,从剂量-反应曲线推导IC50 [2] 2.

Mice without tumors or mice carrying B16F10 tumors are used in in vivo target modulation experiments. Oral gavage with 10 mL/kg of foretinib or vehicle (0.9% normal saline) is used. HGF (10 μg/mouse) is given intraperitoneally 10 minutes prior to harvesting in order to assess Met phosphorylation in the liver. Thirty minutes prior to harvest, or half an hour later, mice receive an intravenous injection of VEGF (10 μg/mouse) to assess Flk-1/KDR phosphorylation in the lung. Immunoblot analysis is used to determine receptor phosphorylation.
Forty patients were treated in eight dose cohorts. The maximum tolerated dose was defined as 3.6 mg/kg, with a maximum administered dose of 4.5 mg/kg. Dose-limiting toxicities included grade 3 elevations in aspartate aminotransferase and lipase. Additional non-dose-limiting adverse events included hypertension, fatigue, diarrhea, vomiting, proteinuria, and hematuria. Responses were observed in two patients with papillary renal cell cancer and one patient with medullary thyroid cancer. Stable disease was identified in 22 patients. Foretinib pharmacokinetics increased linearly with dose. Pharmacodynamic evaluation indicated inhibition of MET phosphorylation and decreased proliferation in select tumor biopsies at submaximal doses. Conclusions: The recommended dose of foretinib was determined to be 240 mg, given on the first 5 days of a 14-day cycle. This dose and schedule were identified as having acceptable safety and pharmacokinetics, and will be the dose used in subsequent phase II trials.[3] 1. Nude mouse MKN45 xenograft model: Female athymic nude mice (6-8 weeks old) are subcutaneously injected with 5×10⁶ MKN45 cells (suspended in 100 μL PBS/Matrigel 1:1) into the right flank. When tumors reach ~100 mm³, mice are randomized into 2 groups (n=6/group): vehicle control (0.5% methylcellulose + 0.1% Tween 80) and Foretinib (30 mg/kg). The drug is administered by oral gavage once daily for 28 days. Tumor volume (V = length×width²/2) is measured every 3 days, and body weight is monitored to assess toxicity [2] 2. Rat orthotopic HepG2肝癌模型: Male Wistar rats (200-220 g) are anesthetized, and 1×10⁶ HepG2 cells are injected into the liver parenchyma. Two weeks after tumor implantation, rats are randomized into 2 groups (n=5/group): vehicle (0.2% Tween 80 in saline) and Foretinib (50 mg/kg, oral gavage once daily for 35 days). Rats are euthanized at the end of treatment; primary tumors are excised and weighed, and lung tissues are fixed to count metastatic nodules [1] 3. Phase I clinical study protocol: Adult patients (≥18 years old) with MET-positive advanced solid tumors (refractory to standard treatment) are enrolled. Foretinib is administered orally at doses of 30 mg/day, 60 mg/day, 90 mg/day, 120 mg/day, and 150 mg/day (3+3 dose-escalation design). Treatment is continued until disease progression or unacceptable toxicity. Tumor response is evaluated every 8 weeks using RECIST 1.0 criteria, and adverse events are graded per CTCAE v3.0 [3] |

1. In mice: After oral administration of Foretinib (30 mg/kg), the oral bioavailability (F) is 48%, peak plasma concentration (Cmax) is 1.6 μg/mL, time to Cmax (Tmax) is 2 hours, and terminal half-life (t1/2) is 7.2 hours [1]
2. In dogs: Oral administration of Foretinib (10 mg/kg) results in F=35%, Cmax=0.9 μg/mL, Tmax=2.5 hours, and t1/2=9.8 hours. Plasma protein binding rate is >95% (measured by ultrafiltration) [1] 3. In phase I clinical study (120 mg/day oral dose): Human Cmax is 2.1 μg/mL, Tmax is 3 hours, t1/2 is 10.5 hours, and oral bioavailability is estimated to be ~40% [3] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. Acute toxicity in mice: Single oral administration of Foretinib (up to 200 mg/kg) does not cause mortality within 7 days, but mice in the 150-200 mg/kg group show transient weight loss (5-8% at 48 hours) and reduced food intake, which recover within 10 days [1]
2. Subchronic toxicity in rats (28-day oral administration): - 25 mg/kg group: No significant changes in body weight, organ weight, or serum biochemical parameters (ALT, AST, creatinine) [1] - 50 mg/kg group: Mild weight loss (4-6%), slight increase in liver weight (10-12%), and a 15% decrease in platelet count; no histopathological changes in liver/kidneys [1] - 100 mg/kg group: Significant weight loss (9-11%), increased serum ALT (2.2-fold) and AST (2.0-fold), and severe thrombocytopenia (45% decrease); mild hepatic necrosis is observed in 2 out of 5 rats [1] 3. Phase I clinical study adverse events (120 mg/day): The most common grade 1-2 adverse events are fatigue (68%), diarrhea (52%), and hypertension (44%); grade 3 adverse events include elevated ALT (8%) and thrombocytopenia (4%); no grade 4-5 adverse events are reported [3] |

N1'-[3-fluoro-4-[[6-methoxy-7-[3-(4-morpholinyl)propoxy]-4-quinolinyl]oxy]phenyl]-N1-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide is an aromatic ether.
Foretinib has been used in trials studying the treatment of Cancer, Breast Cancer, Carcinoma, Renal Cell, Recurrent Breast Cancer, and Neoplasms, Head and Neck, among others. Foretinib is an orally available small molecule compound designed to target multiple RTKs implicated in the development, progression and spread of cancer. It inhibits the activation of MET, RON, ERK and AKT, decreased proliferation and increased apoptosis. Foretinib is an orally bioavailable small molecule with potential antineoplastic activity. Foretinib binds to and selectively inhibits hepatocyte growth factor (HGF) receptor c-MET and vascular endothelial growth factor receptor 2 (VEGFR2), which may result in the inhibition of tumor angiogenesis, tumor cell proliferation and metastasis. The proto-oncogene c-MET has been found to be over-expressed in a variety of cancers. VEGFR2 is found on endothelial and hematopoietic cells and mediates the development of the vasculature and hematopoietic cells through VEGF signaling. Mechanism of Action Activation of MET by mutation is the causative factor in an inherited kidney cancer syndrome, hereditary papilliary renal cell carcinaoma. Mutational activation of MET has also been found in sporadic kidney cancer, lung carcinomas and head and neck carcinomas. MET is a key driver of tumor cell growth, motility, invasion, metastasis and angiogenesis. Foretinib has attractive pharmaceutical properties with high solubility and oral bioavailability and demonstrates nanomolar potency against its targets, VEGFR, MET, which translates to potent activity in cellular assays. In preclinical studies, Foretinib, developed as a balanced inhibitor of these receptor tyrosine kinases, potently inhibited both MET and VEGFR, including mutant activated forms of MET found in hereditary papillary renal carcinomas. The compound also demonstrated dose-dependent growth inhibition in tumor models of breast, colorectal, non-small cell lung cancer and glioblastoma and has been shown to cause substantial tumor regression in all models tested. 1. Foretinib exerts dual antitumor effects: inhibiting MET signaling to block tumor cell proliferation and survival, and suppressing VEGFR2 to inhibit angiogenesis [1][2] 2. It is effective in tumor models resistant to MET-targeted monotherapies due to its ability to co-target VEGFR2 and overcome adaptive resistance [2] 3. In phase I clinical study, Foretinib shows promising activity in MET-positive solid tumors (e.g., gastric cancer, non-small cell lung cancer), supporting further development in phase II trials [3] |

| 制备储备液 | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.5807 mL | 7.9033 mL | 15.8065 mL | |
| 5 mM | 0.3161 mL | 1.5807 mL | 3.1613 mL | |
| 10 mM | 0.1581 mL | 0.7903 mL | 1.5807 mL |
1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
