Body Protection Compound 157 (BPC 157) is a pentadecapeptide derived from BPC, identified in gastric juice, exhibiting diverse biological activities. At 2 µg/ml, BPC 157 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, BPC 157 reduces catalepsy duration and tremor severity in a mouse model of Parkinson's disease triggered by MPTP.
Troponin I is a cardiac and skeletal muscle protein useful in the laboratory diagnosis of a heart attack. Troponin I is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place.
F-991 is a peptide inhibitor that has shown remarkable biological activity in a number of animal models of allergic diseases, and promise for the potential treatment of allergic diseases in humans.
