AI Technical Summary

Technical Problem

Existing anti-inflammatory drugs for the treatment of ulcerative colitis have problems such as single target, significant side effects and high treatment costs. Furthermore, the active ingredients of the polypeptide mixture extracted from black-boned chicken liver hydrolysate are unclear, making it difficult to achieve standardized application.

Method used

Two specific anti-inflammatory peptides, LSGPIRFF and SDPWWKAF, were precisely identified from the hydrolyzed peptides of black-boned chicken liver. These peptides were prepared by artificial solid-phase synthesis and their anti-inflammatory activity was verified in animal experiments. By combining virtual screening strategy to predict their potential targets and intersection targets, their role in ulcerative colitis was verified.

Benefits of technology

Significantly improves core symptoms of ulcerative colitis, including reducing disease activity index, restoring colon length, improving intestinal histopathological damage, and modulating levels of key pro-inflammatory/anti-inflammatory factors, providing a safe and effective novel therapeutic drug candidate molecule.
