ABSTRACT:
Novel synthetic isohirudins with improved stability The invention relates to novel synthetic isohirudins which have improved stability owing to exchange in the region of the Asp-Gly motif. This results, on the one hand, in an increase in the yield during workup and, on the other hand, in making possible pharmaceutical formulation as directly injectable solution ready for use.
