Peptide Profile
BPC-157 is a synthetic pentadecapeptide with exceptional proteolytic stability. Molecular properties, research history, and documented biochemical activities in preclinical models.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide with the amino acid sequence GEPPPGKPADDAGLV. It consists of 15 amino acids (CAS: 137525-51-0, MW: 1419.56 g/mol) and was originally isolated from human gastric juice. The high proline content — four of the fifteen amino acids are proline — confers extraordinary resistance to enzymatic degradation (proteolysis) upon BPC-157.
BPC-157 was synthesized and characterized in the 1990s by the research group led by Professor Predrag Sikiric at the University of Zagreb (Croatia). It is a partial sequence analogue of the "Body Protection Compound" — a naturally occurring protein in human gastric juice.
Since then, BPC-157 has been investigated in a wide range of preclinical in vitro and in vivo studies. The publication base includes several hundred peer-reviewed articles, predominantly from the Croatian research group as well as increasingly from independent laboratories worldwide.
Research Context
All published data on BPC-157 are derived from preclinical in vitro and in vivo models. No clinical phase II or phase III studies exist. BPC-157 is not an approved medicinal product and is intended exclusively for research purposes.
In preclinical models, BPC-157 has been investigated in the following areas of research:
The exceptional proteolytic stability of BPC-157 is one of the peptide's most scientifically interesting properties. Proline disrupts the regular helical structure of peptide chains and makes the peptide bonds at these sites less accessible to many proteases.
With four proline residues out of fifteen amino acids — a proline content of 26.7% — BPC-157 exhibits significantly higher stability against gastrointestinal and serum proteases than most other linear peptides of comparable length. This makes it an analytically interesting model peptide for stability studies.
