  A dual inhibitor of matrix metalloproteinases and a disintegrin and metalloproteinases, [18F]FB-ML5, as a molecular probe for non-invasive MMP/ADAM-targeted imaging

  摘要：

  Background: Numerous clinical studies have shown a correlation between increased matrix metalloproteinase (MMP)/a disintegrin and metalloproteinase (ADAM) activity and poor outcome of cancer. Various MMP inhibitors (MMPIs) have been developed for therapeutic purposes in oncology. In addition, molecular imaging of MMP/ADAM levels in vivo would allow the diagnosis of tumors. We selected the dual inhibitor of MMPs and ADAMs, ML5, which is a hydroxamate-based inhibitor with affinities for many MMPs and ADAMs. ML5 was radiolabelled with F-18 and the newly obtained radiolabelled inhibitor was evaluated in vitro and in vivo.Materials and methods: ML5 was radiolabelled by direct acylation with N-succinimidyl-4-[F-18]fluorobenzoate ([F-18]SFB) for PET (positron emission tomography). The resulting radiotracer [F-18]FB-ML5 was evaluated in vitro in human bronchial epithelium 16HBE cells and breast cancer MCF-7 cells. The non-radioactive probe FB-ML5 and native ML5 were tested in a fluorogenic inhibition assay against MMP-2, -9, -12 and ADAM-17. The in vivo kinetics of [F-18]FB-ML5 were examined in a HT1080 tumor-bearing mouse model. Specificity of probe binding was examined by co-injection of 0 or 2.5 mg/kg ML5. Results: ML5 and FB-ML5 showed high affinity for MMP-2, -9, -12 and ADAM-17; indeed IC50 values were respectively 7.4 +/- 2.0, 19.5 +/- 2.8, 2.0 +/- 0.2 and 5.7 +/- 2.2 nM and 12.5 +/- 3.1, 31.5 +/- 13.7, 138.0 +/- 10.9 and 24.7 +/- 2.8 nM. Radiochemical yield of HPLC-purified [F-18]FB-ML5 was 13-16% (corrected for decay). Cellular binding of [F-18]FB-ML5 was reduced by 36.6% and 27.5% in MCF-7 and 16HBE cells, respectively, after co-incubation with 10 mu M of ML5. In microPET scans, HT1080 tumors exhibited a low and homogeneous uptake of the tracer. Tumors of mice injected with [F-18]FB-ML5 showed a SUVmean of 0.145 +/- 0.064 (n = 6) which decreased to 0.041 +/- 0.027 (n = 6) after target blocking (p < 0.05). Ex vivo biodistribution showed a rapid excretion through the kidneys and the liver. Metabolite assays indicated that the parent tracer represented 23.2 +/- 7.3% (n = 2) of total radioactivity in plasma, at 90 min post injection (p.i.).Conclusion: The nanomolar affinity MMP/ADAM inhibitor ML5 was successfully labelled with F-18. [F-18]FB-ML5 demonstrated rather low binding in ADAM-17 overexpressing cell lines. [F-18]FB-ML5 uptake showed significant reduction in the HT1080 tumor in vivo after co-injection of ML5. [F-18]FB-ML5 may be suitable for the visualization/quantification of diseases overexpressing simultaneously MMPs and ADAMs. (C) 2014 Elsevier Ltd. All rights reserved.

  A compound library of 96 enantiopure N-terminal succinyl hydroxamate functionalized peptides was synthesized on solid phase. All compounds were tested for their inhibitory potential towards MMP-9, MMP-12 and ADAM-17, which led to the identification of both broad spectrum inhibitors and metalloproteinase-selective ones. Eight potent and less potent inhibitors were immobilized on Sepharose beads and evaluated in solid-phase enrichment of active MMP-9, MMP-12 and ADAM-17. In addition, one of these inhibitors was used for solid-phase enrichment of endogenous ADAM-17 from a complex proteome (a lysate prepared from cultured A549 cells).

  targeting of MMPs by engineering a functionally silent cysteine mutation that enables highly specific covalent modification by a designed activity-based probe. Here, we describe the translation of that technology into a mouse model of breast cancer and subsequent demonstration of the utility of the approach for studies of MMP-14 activation in the tumor microenvironment. Using this approach, we find that MMP-14

  基质金属蛋白酶（MMPs）是锌依赖性内肽酶的一大家族，参与多种生理和病理学过程，特别是在癌症中。当前的成像和定量MMP活性的方法缺乏足够的选择性和时空分辨率，无法进行体内特定MMP功能的研究。以前，我们报道了通过设计功能性沉默的半胱氨酸突变来选择性靶向MMP的策略，该突变使半胱氨酸突变能够通过设计的基于活性的探针进行高度特异性的共价修饰。在这里，我们描述了将该技术翻译成乳腺癌的小鼠模型，并随后证明了该方法在肿瘤微环境中研究MMP-14激活的实用性。使用这种方法，我们发现MMP-14在晚期肿瘤中具有活性，并且主要与已被肿瘤细胞产生的特定信号分子（例如TGFβ）激活的基质细胞群相关。我们的数据证明了该方法在整个生物体中MMP功能研究中的适用性，并确定了肿瘤微环境中MMP-14活性的重要调控机制。
