Synonyms:	(2R*,3R*)-3-{[(2S)-1-({3-[(4-aminobutyl)amino]propyl}amino)-1-oxo-3-phenylpropan-2-yl]carbamoyl}oxirane-2-carboxylic acid
Definition:	An epoxide which is a carboxamide obtained by the formal condensation of one of the carboxy groups of oxirane-2,3-dicarboxylic acid with N-{3-[(4-aminobutyl)amino]propyl}-L-phenylalaninamide. It is a natural product, isolated from Gliocladium sp. F-2665. TMC-52C acts as an inhibitor of cysteine proteinases, particularly cathepsin B (EC 3.4.22.1), cathepsin L (EC 3.4.22.15), and papain (EC 3.4.22.2), with IC50 values of 460 nM, 10 nM, and 88 nM, respectively. The epoxide group has trans configuration but its exact stereochemistry is uncertain: it is either (2R,3R) or (2S,3S).
