RO314724 is a HDAC inhibitor. RO314724 is also a a reversible, tightly binding, MMP inhibitor with a Ki of 26 nm. Matrix metalloproteinases (MMPs) belong to the key enzymes of the proteolytic destruction of cartilage matrix during chronic rheumatic diseases. Ro314724 displayed MMP-proteoglycanase inhibitory activity both in vitro and ex vivo and proved to be not harmful to the morphology, viability and proteoglycan biosynthesis of bovine articular cartilage explants.
Dnp-PLAYWAR is a fluorogenic substrate for matrix metalloproteinase-8 (MMP-8) and MMP-26. The activity of MMP-8 and MMP-26 can be quantified by measuring tryptophan fluorescence that is unquenched upon peptide hydrolysis that removes the N-terminal dinitrophenol (Dnp) group.
