Body Protection Compound 157 (BPC157) is a pentadecapeptide derived from BPC, identified in gastric juice, exhibiting diverse biological activities. At 2 µg ml, BPC157 enhances primary rat tendon fibroblast cell migration and F-actin formation. Furthermore, doses of 0.01 and 10 µg kg, intraperitoneally (i.p.), mitigate paw swelling, bone erosion, and mononuclear cell infiltration in the joints of rats with rheumatoid arthritis induced by complete Freund's adjuvant (CFA). It also diminishes gastric ulcer size in rats caused by indomethacin, aspirin, or diclofenac at these doses. Additionally, BPC157 reduces catalepsy duration and tremor severity in a mouse model of Parkinson's disease triggered by MPTP.
