1. FAK抑制与细胞增殖抑制:在PC-3前列腺癌细胞中,BI-853520抑制FAK Tyr³⁹⁷位点自磷酸化的IC₅₀为1 nM,阻断锚定非依赖性克隆形成的EC₅₀为3 nM。Western blot分析显示,药物处理后p-FAK(Tyr³⁹⁷)及下游信号分子(如Akt、ERK)呈剂量依赖性下调 [1][3]
2. 3D球体与2D单层细胞活性差异:在癌细胞(如PC-3、MDA-MB-231)的3D球体培养中,BI-853520在低剂量(≤3 μM)即可抑制肿瘤细胞增殖和侵袭;而在2D单层培养中,需≥1000倍浓度才能达到类似效果 [1][3] 3. 乳腺癌细胞迁移抑制:在高转移性小鼠乳腺癌细胞中,BI-853520(0.1 μM)可快速抑制FAK磷酸化,Transwell实验显示24小时内细胞迁移率降低50% [2] 4. 与间充质表型的相关性:体外实验证实,对BI-853520的敏感性与E-钙黏蛋白表达缺失及间充质标志物(如波形蛋白、N-钙黏蛋白)激活密切相关,免疫荧光染色可验证该关联 [1][3] |
| 体内研究 (In Vivo) |
1. 腺癌异种移植模型疗效:在荷PC-3腺癌皮下异种移植瘤的裸鼠中,口服BI-853520(50 mg/kg/天)2周内可使肿瘤体积缩小60–80%,20%的小鼠肿瘤完全消退。间充质表型肿瘤(低E-钙黏蛋白、高miR-200c-3p)对药物响应更显著,中位肿瘤生长抑制率(TGI)>100% [1][3]
2. 药效动力学靶点结合:免疫组化结果显示,BI-853520可快速穿透肿瘤组织,给药后1小时内即可抑制>90%的p-FAK(Tyr³⁹⁷),且靶点抑制效果可持续≥24小时 [1][3] 3. 乳腺癌原位模型疗效:在荷MDA-MB-231乳腺癌原位瘤的BALB/c裸鼠中,口服BI-853520(50 mg/kg/天)14天后,肿瘤细胞增殖(Ki-67染色)和血管生成(CD31⁺血管)较溶剂对照组减少40–60% [2] |
| 酶活实验 |
1. 重组FAK激酶活性实验:将纯化的人FAK激酶结构域与ATP(10 μM)及荧光肽底物(序列:KVEKIGEGTYGVVYK)在激酶缓冲液(50 mM Tris-HCl,pH 7.5,10 mM MgCl₂,1 mM DTT)中孵育。加入BI-853520(0.1–1000 nM)后,30°C反应30分钟。通过荧光偏振仪定量磷酸化水平,IC₅₀定义为信号抑制50%的药物浓度 [1][3]
2. 激酶选择性分析:在200余种重组激酶组成的筛选面板中测试BI-853520(1 μM),结果显示其对FAK的选择性超过1000倍(对Src、Abl、VEGFR2等非靶激酶的抑制率<5%)[1][3] |
| 细胞实验 |
1. 3D球体形成实验:将癌细胞(5×10³细胞/孔)包埋于Matrigel(10 mg/mL)中,接种于96孔超低吸附板,用BI-853520(0.1–10 μM)处理7天。通过明场显微镜(ImageJ软件)测量球体直径,Calcein-AM染色(激发光485 nm,发射光520 nm)评估细胞活性。3 μM BI-853520可使球体直径缩小≥50% [1][3]
2. Transwell迁移/侵袭实验:迁移实验使用未包被的Transwell小室(8-μm孔径),侵袭实验使用包被Matrigel(50 μg/小室)的小室。将经BI-853520(1–10 μM)处理的细胞(1×10⁵细胞/小室)接种于上室(无血清培养基),下室加入10%胎牛血清。24小时后,去除未迁移/侵袭的细胞,结晶紫染色后显微镜计数。10 μM BI-853520可使MDA-MB-231细胞迁移率降低60% [2] 3. 凋亡检测实验:PC-3细胞经BI-853520(5 μM)处理48小时后,按试剂盒说明书用Annexin V-FITC和碘化丙啶(PI)染色。通过流式细胞术定量凋亡细胞(Annexin V⁺/PI⁻和Annexin V⁺/PI⁺),结果显示凋亡率较溶剂对照组增加2–3倍;western blot可验证caspase-3激活 [1][3] |
| 动物实验 |
1. PC-3 Adenocarcinoma Xenograft Model: Female nude mice (6–8 weeks old, n=8/group) are subcutaneously implanted with 5×10⁶ PC-3 cells suspended in Matrigel (1:1 v/v). When tumors reach ~100 mm³, mice receive BI-853520 formulated in 0.5% methylcellulose (w/v) via oral gavage at 50 mg/kg once daily for 21 days. Tumor volume is measured twice weekly using calipers (V = 0.5 × length × width²), and mice are euthanized on day 21. Tumors are harvested for immunohistochemistry (p-FAK, Ki-67) and western blot analysis [1][3]
2. MDA-MB-231 Breast Cancer Orthotopic Model: Female BALB/c nude mice (6–8 weeks old, n=8/group) are anesthetized, and 2×10⁶ MDA-MB-231 cells (suspended in 50 μL PBS) are injected into the fourth mammary fat pad. Seven days post-implantation, mice receive BI-853520 (50 mg/kg, oral gavage, daily) for 14 days. Primary tumor weight is measured at euthanasia, and lung metastasis is evaluated by hematoxylin-eosin (HE) staining of lung sections [2] |
| 药代性质 (ADME/PK) |
1. Oral Absorption and Plasma Pharmacokinetics: In mice, oral administration of BI-853520 (50 mg/kg) shows >80% bioavailability. Peak plasma concentration (Cmax) of 2–3 μM is achieved at 1–2 hours post-dose, and the terminal half-life (t₁/₂) is 8–10 hours, supporting once-daily dosing [1][3]
2. Tissue Distribution and Excretion: BI-853520 distributes widely into tissues, with a tumor/plasma concentration ratio of >2:1 at steady state (day 7 of daily dosing). It is primarily metabolized by hepatic CYP3A4/5, with <5% of the dose excreted unchanged in urine within 24 hours [1][3] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. Preclinical Acute and Chronic Toxicity: In Sprague-Dawley rats (n=6/group) treated with BI-853520 (50, 100, 200 mg/kg daily, oral) for 28 days, no significant changes in body weight, organ weights (liver, kidney, heart), or hematological parameters (RBC, WBC, platelets) are observed. Mild transient proteinuria (<30 mg/dL) is noted in 10–15% of rats at 200 mg/kg, resolving within 48 hours of dose interruption [1][3]
2. Tumor Tissue Toxicity: In xenograft models, BI-853520 (50 mg/kg daily) causes no significant necrosis or inflammation in normal tissues (e.g., liver, kidney), as shown by HE staining [1][3] |

| 其他信息 |
1. Mechanism of Action: BI-853520 is an ATP-competitive inhibitor of FAK that disrupts integrin-mediated signaling pathways, leading to reduced tumor cell adhesion, migration, and survival. It also inhibits FAK-dependent stromal cell recruitment, suppressing tumor microenvironment support [1][3]
2. Biomarker for Sensitivity: Preclinical studies confirm that loss of E-cadherin and low miR-200c-3p expression are predictive biomarkers for BI-853520 efficacy, as mesenchymal-phenotype tumors show significantly higher response rates than epithelial-phenotype tumors [1][3] 3. Clinical Relevance in Breast Cancer: In breast cancer models, BI-853520 targets metastatic potential by inhibiting FAK-mediated cell migration, supporting its development for metastatic breast cancer [2] 4. Formulation Advantage: The oral formulation of BI-853520 (0.5% methylcellulose) shows good stability and bioavailability, facilitating preclinical-to-clinical translation [1][3] |
