Popis: Abstract: Z-Phe-Pro-(isonicotinic acid methylester) methylketone is a highly potent inhibitor (Ki*= 18 nM) of prolyl endopeptidase from Flavobacterium meningosepticum. It acts as a slow-binding inhibitor and decomposes to compounds still possessing inhibitory activity.The pathway of decomposition was analyzed qualitatively and quantitatively applying MALDI-TOF mass spectrometry.
