Batimastat (BB-94) 是一种基质金属蛋白酶的强抑制剂，其结合方式不寻常。 Batimastat 对明胶酶 A 的 IC50 为 4 nM，对明胶酶 B 的 IC50 为 10 nM。与 MMP-1 (3 nM)、MMP-8 (10 nM) 和 MMP-3 (20 nM) 的结果相当[2]，结构相同的胶原酶 Ht-d 的 IC50 为 6 nM。这种金属蛋白酶抑制剂 Batimastat（BB-94，IC50=230 nM）基于异羟肟酸，可成功抑制细胞系 Karpas299 中 CD30 的脱落[3]。

在人乳腺癌原位模型中，鞘内治疗 Batimastat (BB-94) 显着抑制人卵巢癌异种移植物和小鼠黑色素瘤转移的生长，同时延迟原发肿瘤的生长，而不引起细胞毒性或改变 mRNA 水平[2]。合成基质金属蛋白酶抑制剂巴马司他 (BB) -94 在多种肿瘤类型中已证实具有抗肿瘤和抗血管生成特性。所有动物在接受巴马司他（每隔一天 60 毫克/公斤腹腔注射，总共注射 8 次）和顺铂（静脉注射 4 毫克/公斤，每 7 天，总共注射 3 次）治疗后第 200 天均存活且状况良好），这完全阻止了两种异种移植物的生长和扩散[4]。根据 Kaplan-Meier 生存分析（48 小时），与对照组 (75%) 相比，用 Batimastat (BB-94) 治疗的动物具有更高的生存率 (95.2%)，并且这些变化几乎具有统计显着性 (p= 0.064）[5]。 E2 给药后四小时（激素治疗后胶原蛋白密度最低的时期）在用盐水或巴马司他 (40 mg/kg) 预处理的动物中评估基质密度[6]。

Batimastat is a secondary carboxamide resulting from the formal condensation of the carboxy group of (2S,3R)-5-methyl-3-{[(2S)-1-(methylamino)-1-oxo-3-phenylpropan-2-yl]carbamoyl}-2-[(thiophen-2-ylsulfanyl)methyl]hexanoic acid with the amino group of hydroxylamine. It a broad-spectrum matrix metalloprotease inhibitor. It has a role as a matrix metalloproteinase inhibitor, an antineoplastic agent and an angiogenesis inhibitor. It is a L-phenylalanine derivative, a member of thiophenes, an organic sulfide, a triamide, a hydroxamic acid and a secondary carboxamide.

Batimastat is a synthetic hydroxamate with potential antineoplastic activity. Batimastat binds covalently to the zinc ion in the active site of matrix metalloproteinases (MMPs), thereby inhibiting the action of MMPs, inducing extracellular matrix degradation, and inhibiting angiogenesis, tumor growth and invasion, and metastasis. An anticancer drug that belongs to the family of drugs called angiogenesis inhibitors. Batimastat is a matrix metalloproteinase inhibitor.

Matrix metalloproteinases have been implicated in the growth and spread of metastatic tumors. This role was investigated in an orthotopic transplant model of human colon cancer in nude mice using the matrix metalloproteinase inhibitor BB-94 (batimastat). Fragments of human colon carcinoma (1-1.5 mm) were surgically implanted orthotopically on the colon in 40 athymic nu/nu mice. Administration of BB-94 or vehicle (phosphate buffered saline, pH 7.4, containing 0.01% Tween 80) commenced 7 days after tumor implantation (20 animals/group). Animals received 30 mg/kg BB-94 i.p. once daily for the first 60 days and then 3 times weekly. Treatment with BB-94 caused a reduction in the median weight of the primary tumor from 293 mg in the control group to 144 mg in the BB-94 treated group (P < 0.001). BB-94 treatment also reduced the incidence of local and regional invasion, from 12 of 18 mice in the control group (67%) to 7 of 20 mice in the treated group (35%). Six mice in the control group were also found to have metastases in the liver, lung, peritoneum, abdominal wall, or local lymph nodes. Only two mice in the BB-94 group had evidence of metastatic disease, in both cases confined to the abdominal wall. The reduction in tumor progression observed in the BB-94-treated group translated into an improvement in the survival of this group, from a median survival time of 110 days in the control group to a median survival time of 140 days in the treated group (P < 0.01). Treatment with BB-94 was not associated with any obvious toxic effect, and these results suggest that such agents may be effective as adjunctive cancer therapies.

The synthetic matrix metalloproteinase inhibitor batimastat was tested for its ability to inhibit growth and metastatic spread of the B16-BL6 murine melanoma in syngeneic C57BL/6N mice. Intraperitoneal administration of batimastat resulted in a significant inhibition in the number of lung colonies produced by B16-BL6 cells injected i.v. The effect of batimastat on spontaneous metastases was examined in mice inoculated in the hind footpad with B16-BL6 melanoma. The primary tumor was removed surgically after 26-28 days. Batimastat was administered twice a day from day 14 to day 28 (pre-surgery) or from day 26 to day 44 (post-surgery). With both protocols, the median number of lung metastases was not significantly affected, but there was a significant reduction in the weight of the metastases. Finally, the effect of batimastat was examined on s.c. growth of B16-BL6 melanoma. Batimastat administered daily, starting at day of tumor transplantation, resulted in a significant growth delay, whereas treatment starting at advanced stage tumor only reduced tumor growth marginally. Our results indicate that a matrix metalloproteinase inhibitor can not only prevent the colonization of secondary organs by B16-BL6 cells but also limit the growth of solid tumors.
