Abstract: Matrix metalloproteinases (MMPs) are a family of zinc-containing proteases that participate in many physiological and pathological processes in vivo. Recently, the MMP network has been established according to a deeper understanding of its functions. Some MMPs have been also regarded as biomarkers of various diseases, including inflammation, nerve diseases, and cancers. MMP labelling has been thus paid more attention in recent decades. Accordingly, both reagents and technologies for MMP labelling have been rapidly developed. Here we summarize the recent development of some MMP labelling methods. This review was identified through keyword (MMPs; labelling; etc.) searches in the ScienceDirect database, Scifinder, Web of Science, and PubMed for which typical cases were used for an inductive overview. In spite of the advances in MMP labelling, selective labelling of a specific MMP is still an open issue. We hope that this article can be helpful in developing specific MMP labelling methods in future.

Aβ2,β3-homoproline derivative, (2S, 2′S)-3-phenyl-2-(pyrrolidin-2′-yl)propionic acid, was synthesized starting from l-proline. After preparation of the (4S, 4aS)-4-benzyl-4a,5,6,7-tetrahydro-pyrrolo-[1,2-c]pyrimidine-1,3-dione under a mild condition, the absolute configuration of target compound was assigned using 2D H-H COSY and H-H NOESY technologies.
