In the realm of infectious diseases, peptide-conjugated phosphorodiamidate morpholino oligomer-PPMO constructs have shown remarkable promise. Studies have demonstrated that these molecules can restore carbapenem susceptibility to NDM-1-positive pathogens by targeting essential genes within bacteria, thereby re-sensitizing them to previously ineffective antibiotics. This development is particularly significant in the face of rising antimicrobial resistance, offering a potential strategy to combat multidrug-resistant infections. For example, research has shown that Peptide Conjugated Phosphorodiamidate Morpholino Oligomers have the potential of being used as antisense antibiotics to treat infections caused by pathogens like *Bacillus anthracis*.

Beyond infectious diseases, PPMOs are also being investigated for their potential in treating genetic disorders. In Duchenne muscular dystrophy (DMD), a debilitating genetic condition characterized by the absence of functional dystrophin protein, PPMOs can be designed to correct the underlying genetic defect. Specifically, these molecules can facilitate exon skipping, a process that restores the reading frame of the dystrophin gene, allowing for the production of a truncated but functional dystrophin proteinSeveral studies have demonstrated the efficacy of CPP-conjugatedPMOs in delivering them into various cell types and tissues, including zebrafish embryos, .... This approach has led to promising results in preclinical models, where PPMOs have been shown to restore the DMD reading frame, enabling the production of internally truncated but functional dystrophin. Furthermore, investigations into novel antisense oligonucleotide conjugates that cause exon skipping in the human dystrophin gene highlight the therapeutic potential in treating Duchenne muscular dystrophy.
