JNJ-1289 is a potent, selective, competitive and allosteric human spermine oxidase (hSMOX) inhibitor (IC50: 50 nM). JNJ-1289 can be used in the research of polyamine catabolism, inflammation and cancers.
JNJ-1289 (0.1 nM-1 μM, 0 and 2 h) inhibits hSMOX activity in a time-dependent manner[1].
JNJ-1289 initially forms a weak complex with hSMOX with an apparent Ki value of 1.4 μM, followed by a relatively slow protein isomerization that forms the final tightly bound inhibitor-enzyme complex[1].
