摘要：
Peptides having essentially the sequence of bovine pancreatic trypsin inhibitor (aprotinin) wherein one or more of the amino acids at positions 15, 16, 17, 18, 34, 39 and 52 are replaced by any naturally occurring amino acid produced by recombinant DNA technology, process, expression vector and recominant host therefor and pharmaceutical use thereof. Such peptides being useful as therapeutic agents in diseases connected with the presence of excessive amounts of proteinases.
