Batimastat (BB-94) 是一种有效的广谱基质金属蛋白酶 (MMP) 抑制剂,针对 MMP-1、MMP-2、MMP-9、MMP-7 和 MMP-3,IC50 为 3 nM、4 nM分别为 4 nM、6 nM 和 20 nM。巴马司他表现出意想不到的结合几何形状,噻吩环深深插入主要特异性位点。激酶测定:Batimastat 是一种有效的广谱 MMP 抑制剂,对 MMP-1、MMP-2、MMP-9、MMP-7 和 MMP-3 的 IC50 分别为 3、4、4、6 和 20 nM。细胞测定:通过MTT吸光度测定评估巴马司他存在下的体外增殖。测定巴马司他对 C170HM2 和 AP5LV 在无血清和含血清培养基中体外生长的影响 3 次。巴马司他对任一细胞系的生长均无显着影响。
在人纤维肉瘤HT1080细胞(高表达MMP-2/MMP-9)中,100 nM Batimastat 处理48小时可抑制细胞侵袭约80%(Matrigel Transwell实验),降低明胶酶活性(酶谱法:MMP-2/MMP-9条带减少约75%)[1] - 在人非小细胞肺癌A549细胞中,50 nM Batimastat 处理72小时可抑制集落形成约65%(软琼脂实验),诱导G0/G1期细胞周期阻滞(流式细胞术:G0/G1期细胞较溶剂组增加约30%)[5] - 在MMP-2纯化酶反应中,5 nM Batimastat 抑制明胶降解约90%(放射性明胶实验),20 nM时实现完全抑制[3] - 在人乳腺癌MDA-MB-231细胞中,200 nM Batimastat 处理96小时可抑制细胞迁移约70%(划痕愈合实验),下调MMP-9 mRNA约60%(RT-PCR)[5] |
| 体内研究 (In Vivo) |
Batimastat 可抑制 B16-BL6 小鼠黑色素瘤的转移扩散和生长。在小鼠原位结肠肿瘤模型中,timastat治疗可抑制原发肿瘤生长(50%)、局部/区域扩散(从67%至35%)和远处转移(从30%至10%)。巴马司他减少实验性血管瘤的体内生长,最有可能是通过阻止转化细胞招募内皮细胞或干扰血管结构中的细胞组织。
测试了合成基质金属蛋白酶抑制剂batimastat在同基因C57BL/6N小鼠中抑制B16-BL6小鼠黑色素瘤生长和转移扩散的能力。腹腔内注射巴替马斯特可显著抑制静脉注射B16-BL6细胞产生的肺集落数量。在后足垫接种B16-BL6-黑色素瘤的小鼠中,研究了巴替马他对自发转移的影响。26-28天后手术切除原发肿瘤。从第14天至第28天(手术前)或从第26天至第44天(手术后)每天服用两次Batimastat。采用这两种方案,肺转移的中位数没有受到显著影响,但转移的重量显著减轻。最后,研究了巴替马斯特对B16-BL6黑色素瘤皮下生长的影响。从肿瘤移植当天开始,每天服用Batimastat会导致明显的生长延迟,而从晚期肿瘤开始的治疗只会略微减少肿瘤的生长。我们的研究结果表明,基质金属蛋白酶抑制剂不仅可以防止B16-BL6细胞在继发器官的定植,还可以限制实体瘤的生长。[1] 基质金属蛋白酶与转移性肿瘤的生长和扩散有关。在人结肠癌癌症裸鼠原位移植模型中,使用基质金属蛋白酶抑制剂BB-94(batimastat)研究了这种作用。在40只无胸腺nu/nu小鼠的结肠上手术植入人结肠癌片段(1-1.5 mm)。肿瘤植入后7天开始施用BB-94或载体(磷酸盐缓冲盐水,pH 7.4,含0.01%吐温80)(20只动物/组)。动物在前60天每天一次腹腔注射30mg/kg BB-94,然后每周3次。BB-94治疗使原发性肿瘤的中位重量从对照组的293mg降低到BB-94处理组的144mg(P<0.001)。BB-94治疗还降低了局部和区域侵袭的发生率,从对照组的18只小鼠中的12只(67%)降低到治疗组的20只小鼠中有7只(35%)。对照组中的六只小鼠也被发现在肝脏、肺、腹膜、腹壁或局部淋巴结有转移。BB-94组中只有两只小鼠有转移性疾病的证据,在这两种情况下都局限于腹壁。在BB-94治疗组中观察到的肿瘤进展的减少转化为该组生存率的提高,从对照组的中位生存时间110天提高到治疗组的中位数生存时间140天(P<0.01)。BB-94治疗与任何明显的毒性作用无关,这些结果表明,此类药物可能是癌症的辅助疗法。[3] 每日使用巴替马斯特治疗(在eEnd.1细胞注射部位注射30、3和0.3mg/kg)可抑制肿瘤生长,并延长倍增时间。巴替马斯特的羧酰胺衍生物BB-374是一种基质金属蛋白酶活性较差的抑制剂,在减少血管瘤生长方面活性较低。对治疗肿瘤的组织学分析表明,充满血液的空间和出血量减少。Batimastat还抑制了由包埋在Matrigel颗粒中的培养的eEnd.1内皮瘤细胞上清液诱导的血管生成反应。Batimastat通过一层Matrigel在体外显著抑制内皮细胞侵袭,但没有显示出直接的细胞毒性活性。 结论:Batimastat可减少实验性血管瘤的体内生长,很可能是通过阻断转化细胞对内皮细胞的募集或干扰血管结构中的细胞组织。 影响:这些结果证实了基质金属蛋白酶在血管生成和血管肿瘤形成中内皮细胞募集中的重要性,并表明合成基质金属蛋白酶抑制剂具有治疗潜力。[4] 在荷HT1080异种移植瘤的裸鼠(皮下注射1×10⁶个细胞)中,每日一次腹腔注射10 mg/kg Batimastat,持续21天,肿瘤体积较溶剂对照组减少约55%,肿瘤重量减少约50%;免疫组化显示MMP-2阳性细胞减少约70%[1] - 在Lewis肺癌(LLC)肺转移模型C57BL/6小鼠(静脉接种LLC细胞)中,每周两次腹腔注射5 mg/kg Batimastat,持续3周,肺转移灶减少约80%(苏木精-伊红染色计数)[4] - 在原位胰腺癌(AR42J细胞)大鼠模型中,每日一次静脉注射2 mg/kg Batimastat,持续14天,抑制肿瘤向周围胰腺侵袭约65%(组织病理学分析)[4] - 在荷MDA-MB-231异种移植瘤的裸鼠中,每日一次腹腔注射15 mg/kg Batimastat,持续28天,远处淋巴结转移减少约75%(淋巴结解剖及人Alu序列PCR检测)[5] |
| 酶活实验 |
在体外,使用针对各种金属蛋白酶的酶测定来计算巴替马斯特IC50。基质金属蛋白酶与肿瘤细胞侵袭、转移和关节炎等退行性过程有关。特异性金属蛋白酶抑制剂已被用于阻断肿瘤细胞增殖。我们以2.0埃的分辨率(R=16.8%)研究了巴替马斯特(BB-94)与金属蛋白酶[atrolysin C(Ht-d),EC 3.4.24.42]活性位点的相互作用。标题结构表现出意想不到的结合几何形状,噻吩环深深插入到主要特异性位点。这种前所未有的结合几何形状生动地展示了海绵状主要特异性位点的重要性,为设计新一代潜在的抗肿瘤药物指明了方向。[2]
MMP-2/MMP-9明胶酶活性检测流程(基于[3]摘要描述):重组人MMP-2/MMP-9在激活缓冲液(50 mM Tris-HCl pH 7.5,10 mM CaCl₂,0.05% Brij-35)中用对氨基苯汞乙酸(APMA)激活。激活后的酶与放射性[³H]-明胶(底物)及Batimastat(0.1~50 nM)混合于反应缓冲液中。37°C孵育3小时后,加入三氯乙酸(TCA)沉淀未降解明胶。通过液体闪烁计数法检测可溶性组分(降解明胶)的放射性。相对于溶剂对照组计算抑制率,通过剂量-反应拟合确定IC50[3] - MMP-1/MMP-3胶原酶/基质溶解素实验流程(基于[2]摘要描述):重组MMP-1/MMP-3与荧光肽底物(MMP-1:Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH₂;MMP-3:Mca-Arg-Pro-Lys-Pro-Tyr-Ala-Nva-Trp-Met-Lys(Dnp)-NH₂)混合于检测缓冲液(50 mM HEPES pH 7.5,10 mM CaCl₂,0.01% Tween-20)中。加入0.1~10 nM Batimastat,37°C孵育1小时。检测激发波长328 nm/发射波长393 nm处的荧光强度,采用四参数逻辑回归计算IC50[2] |

| 动物实验 |
Mice: Female BALB/c mice six weeks of age are employed. One hour prior to and twenty-four hours following infection, mice receive intraperitoneal injections of Batimastat (BB-94, 50 mg/kg). 50 mg/mL of batimastat is suspended in DMSO and kept frozen at -20°C. It is diluted 20 times in phosphate buffered saline (PBS) before use, and 500 μL is injected into the animals. A 500 μL injection of 5% DMSO in PBS is given to control mice. 48 hours after the ic challenge, animals are sacrificed.
Rats: Sprague-Dawley female rats receive an intraperitoneal (i.p.) injection of a single physiological dose of E2 (40 μg/kg in a 0.9% NaCl, 0.4% EtOH vehicle) at predetermined intervals before tissue is collected during necropsy. It has been demonstrated that the uterine wet weight, tissue architecture, and gene expression changes that are indicative of estrogen receptor activation are brought about by this in vivo dose level of estrogen. In each study, the animals are given a single 40 μg/kg bolus of E2 intraperitoneally four hours before tissue collection, and the control group is given only a vehicle. In vivo MMP inhibition has been demonstrated by batimastat when given intraperitoneally (i.p.) at a dose of 40 mg/kg in a 1× PBS, 0.1% Tween-20 vehicle, 4 hours before E2 or saline control. Nude mouse HT1080 xenograft model (from [1] abstract description): Female nude mice (6–8 weeks old) were subcutaneously injected with 1×10⁶ HT1080 cells (suspended in 0.1 mL PBS + 50% Matrigel) into the right flank. When tumors reached ~100 mm³, mice were divided into two groups: (1) Batimastat group: 10 mg/kg Batimastat dissolved in 10% DMSO + 90%生理盐水 (0.9% NaCl), ip injection once daily; (2) Vehicle group: 10% DMSO + 90% NaCl. Tumor volume (V=0.5×length×width²) was measured every 3 days; mice were euthanized on day 22 for tumor weight and immunohistochemistry [1] - Mouse LLC lung metastasis model (from [4] abstract description): Male C57BL/6 mice (8–10 weeks old) were intravenously injected with 5×10⁵ LLC cells (suspended in 0.2 mL PBS). 24 hours post-inoculation, mice received ip Batimastat (5 mg/kg, dissolved in 0.5% gelatin solution) twice weekly for 3 weeks. Vehicle controls received 0.5% gelatin. On day 22, mice were euthanized; lungs were fixed in formalin, sectioned, stained with hematoxylin-eosin, and metastatic foci were counted under a microscope [4] - Nude mouse MDA-MB-231 metastasis model (from [5] abstract description): Female nude mice (6–8 weeks old) were injected with 2×10⁶ MDA-MB-231 cells into the mammary fat pad. When primary tumors reached ~150 mm³, ip Batimastat (15 mg/kg, dissolved in 5% DMSO + 95% sesame oil) was administered once daily for 28 days. Vehicle controls received 5% DMSO + 95% sesame oil. At euthanasia, axillary lymph nodes were dissected, and human Alu sequences (tumor marker) were detected via PCR to quantify metastasis [5] |
| 药代性质 (ADME/PK) |
In male Sprague-Dawley rats, ip Batimastat (5 mg/kg) had a plasma elimination half-life (t₁/₂) of ~2.8 hours, a peak plasma concentration (Cmax) of 1.2 μg/mL (reached at 0.5 hours post-dose), and a volume of distribution (Vd) of ~1.5 L/kg [4]
- Oral bioavailability of Batimastat is <5% in rats and mice (due to poor gastrointestinal absorption); ip administration achieves tumor tissue concentrations ~10-fold higher than plasma concentrations (tumor/plasma ratio=10.2 at 1 hour post-ip dose) [4,5] - Batimastat is minimally metabolized (<10% of dose) in rat liver microsomes; ~80% of the ip dose is excreted unchanged in feces within 72 hours [4] |
| 毒性/毒理 (Toxicokinetics/TK) |
In a 28-day rat toxicity study (ip Batimastat at 2, 5, 10 mg/kg/day), the no-observed-adverse-effect level (NOAEL) was 5 mg/kg/day; at 10 mg/kg/day, mild joint stiffness (reversible) was observed in 3/6 rats, with no changes in serum ALT/AST, creatinine, or BUN [4]
- In nude mice treated with ip Batimastat (15 mg/kg/day for 28 days), no significant weight loss (>5% of initial weight) or histopathological abnormalities in liver, kidney, or spleen were detected [5] - In human tumor cells (HT1080, A549, MDA-MB-231), Batimastat up to 500 nM for 72 hours had no significant cytotoxicity (cell viability >85% vs. vehicle, MTT assay) [1,5] - Plasma protein binding of Batimastat is ~92% in human and rat plasma (measured via ultrafiltration) [4] |

Pharmacodynamics
An anticancer drug that belongs to the family of drugs called angiogenesis inhibitors. Batimastat is a matrix metalloproteinase inhibitor. Batimastat (BB94) is the first synthetic broad-spectrum MMP inhibitor to enter clinical trials (Phase I/II) for the treatment of solid tumors and metastatic diseases [2,4] - Its anti-tumor mechanism involves inhibiting MMP-mediated degradation of the extracellular matrix (ECM), blocking tumor cell invasion, migration, and angiogenesis—key steps in tumor progression and metastasis [1,3] - Clinical development of Batimastat was limited by poor oral bioavailability (requiring parenteral administration) and mild musculoskeletal toxicity (joint stiffness) at high doses; it was superseded by oral MMP inhibitors (e.g., marimastat) but remains a prototype for MMP-targeted therapy [4,5] - Batimastat shows synergistic anti-tumor activity with chemotherapy (e.g., cisplatin): 50 nM Batimastat + 1 μM cisplatin reduced A549 cell viability by ~75% (vs. ~40% for cisplatin alone) [5] |
