(RXR) 4XB

(RXR) 4XB is a cell-penetrating peptide that binds to phosphorodiamidate morpholino oligomer (PMO), resulting in a peptide-conjugated PMO (PPMO) and enhancing the delivery of PMO into bacterial cells. The (RXR) 4XB-PMO conjugate prevents biofilm formation, inhibits Pseudomonas aeruginosa (with an MIC50 of 0.5-16 μM), and reduces bacterial load in a mouse acute pneumonia model.
