JNJ0966 is a potent and highly selective inhibitor of matrix metalloproteinase-9 (MMP-9) zymogen activation. It appears th at JNJ0966 binds to a structural pocket in proximity to the MMP-9 zymogen cleavage site near Arg-106. JNJ0966 reduces disease severity in in a mouse experimental autoimmune encephalomyelitis (EAE) model. JNJ0966 does not inhibit activation of MMP-2 zymogen, and has no effect on MMP-1, MMP-2, MMP-3, MMP-9 or MMP-14 catalytic activity.
