Abstract
The present invention relates to aprotinin variants having improved enzyme-inhibitory, immunological and pharmacokinetic properties and their preparation.
Claims
exact text as granted — not AI-modified1 . Aprotinin variants having a net charge of +3 to −3 at pH 7 and with the amino acids Arg15 or Arg15-Ala17 in the binding region.
2 . Aprotinin variants according to claim 1 for the inhibition of serine proteases.
3 . Aprotinin variants according to claim 1 having a modified N-terminal sequence.
