NNGH is a cell-permeable, broad-spectrum inhibitor of matrix metalloproteinases (MMPs). It blocks the activity of MMP-8, -9, -12, -13, and -20 with Ki values of 9, 2.6, 4.3, 3.1, and 17 nM, respectively. It also inhibits MMP-1, -3, -7, and -10 with Ki values of 0.17, 0.13, 13, and 0.1 μM, respectively. It is commonly used to study the role of MMP-3 (stromelysin 1) in biological systems.
