Single morphic forms of known peptide metalloproteinase inhibitors

摘要

The present invention pertains to single morphic forms of a compound selected from 2S-[4-(2,5-dioxopyrrolidin-1-yl)-2S-mercaptobutyrylamino]4-methylpentanoic acid (2,2-dimethyl-1S-methylcarbamoylpropyl)amide and 2S-[2S-mercapto-4-(3,4,4-trimethyl-2,5-dioxoimidazolidin-1-yl)butyrylamino]-4-methylpentanoic acid (2,2-dimethyl-1S-methylcarbamoylpropyl)amide, isolable as such.
