N-{(2R,4R,5S)-2-benzyl-5-[(tert-butoxycarbonyl)amino]-4-hydroxy-6-phenylhexanoyl}-L-leucyl-N-{15,25,41,49-tetraoxo-53-[(3aS,4S,6aR)-2-oxohexahydro-1H-thieno[3,4-d]imidazol-4-yl]-4,7,10,17,20,23,30,33,36-nonaoxa-44,45-dithia-14,26,40,48-tetraazatripentacont-1-yl}-L-phenylalaninamide
GCB is an organic disulfide that is L-685,458 in which the C-terminal amide group is coupled to a biotin moiety via a long linker containing the disulfide group. It has a role as an EC 3.4.23.46 (memapsin 2) inhibitor. It is an organic disulfide, a polyether, a secondary alcohol, a carbamate ester and a monocarboxylic acid amide. It is functionally related to a biotin and a L-685,458.
