The beneficial effect of BPC 157, a 15 amino acid peptide BPC fragment,on gastric and duodenal lesions induced by restraint stress,cysteamine and 96% ethanol in rats. A comparative study with H2 receptor antagonists,dopamine promotors and gut peptides

The protection of stomach and duodenum in conjecture with anti-inflammatory effect was demonstrated for a novel 15 amino acid peptide, coded BPC 157, a fragment of the recently discovered gastric juice peptide BPC. BPC 157 (i.p./i.g.) was investigated in rats in comparison with several reference standards in three experimental ulcer models (48 h-restriant stress, subcutaneous cysteamine, intragastrical 96% ethanol ulcer tests) (pre-/co-/post-treatment). Only BPC 157 regimes were consistently effective in all of the tested models. On the other hand, bromocriptine, amantadine, famotidine, cimetidine and somatostatin were in effective (restraint stress). A dose-dependent protection (cysteamine) and/or partial positive effect (related to treatment conditions) (ethanol), was obtained with glucagon, NPY and secretin whereas CCK/26– 30/ was not effective. Based on Monastral blue studies BPC 157 beneficial effect appears to be related to a strong endothelial protection.
