Background:

IC50: 8 nM

MMP-13 Inhibitor is a MMP-13 inhibitor.

Matrix metalloproteinases (MMPs), a family of zinc endopeptidases, can degrade proteins of the extracellular matrix, such as collagens, elastins, matrix glycoproteins, and proteoclycans. Zymogen activation and endogenous tissue inhibitors of matrix metalloproteinases control MMP activity during normal morphogenesis and tissue homeostasis. Abnormal expression or activity of MMPs has been reported to be related with pathological processes including metastasis, angiogenesis, cardiovascular disease, and rheumathoid arthritis and osteoarthritis.

In vitro: MMP-13 Inhibitor was previously synthesized as a pyrimidine dicarboxamide that could inhibit the matrix metalloproteinase-13 (MMP-13) with the IC50 of 8 nM. Moreover, MMP-13 Inhibitor was found to be able to bind to MMP pockets that are unique to MMP-13 rather than the catalytic zinc, and therefore was specific for MMP-13 over other MMPs. In addition, during endochondral ossification, MMP-13 Inhibitor could also block osterix-dependent calcification of matrices in limb bud cells [1, 2, 3].

In vivo: So far, there is no animal in vivo study reported.

Clinical trial: So far, no clinical study has been conducted.
