Nature Communications: CAMPER Mechanistic AI Designs WP-CAMPER1 — 12-mer Peptide That Kills MRSA at 4 µg/mL and Reduces Skin-Infection Burden 2.5 log10 in Mice
Fadi Shehadeh, Biswajit Mishra and collaborators published CAMPER (Constraint-driven AMP Engineering with Ranking) in Nature Communications 2026, integrating machine learning with mechanistic biological features to design peptides that target MRSA persister cells. The lead candidate, WP-CAMPER1, kills S. aureus MW2 at a minimal inhibitory concentration of 4 µg/mL. A 2% topical formulation reduced bacterial burden 2.5 log10 in a murine prophylactic skin infection model; the D-enantiomer WP-CAMPER1-d achieved 1.37 log10 reduction in established biofilm infections.
