However, due to moderate efficiency and potential side effects of first-line drugs, it is desirable to develop more efficient anti-UC agents. The natural peptide Melittin, which is the main active ingredient of bee venom, is considered as a potential scaffold for the development of anti-UC drugs. Nevertheless, as a linear amphipathic peptide, Melittin could be degraded by various proteases, suffering from poor stability and short half-lives. Previous studies on structural optimization or the potential of Melittin-derived peptides for anti-UC applications still remain limited. In this study, the stability-guided optimization and anti-UC evaluation were conducted on Melittin. The robust synthetic strategy, in vivo anti-UC activity, and anti-inflammatory mechanism were investigated. Compared with Melittin, the derived peptides represented by PCJ-675 were found to exhibit improved proteolytic stability. In the dextran sulfate sodium (DSS)-induced UC mice model, PCJ-675 could significantly alleviate both colon shortening and suppress inflammation symptoms in colon tissue. The western blotting and biochemical indicators suggested that the oral administration of PCJ-675 could protect the colon in colitis mice by inhibiting both the excessive activation of the inflammation-related TLR4/NF-κB pathway and the overexpression of pro-inflammatory cytokines (eg, IL-1β, IL-6, and TNF-α).
