the peptide platform in detail

The peptides are cationic and are drawn to the negatively charged bacterial membrane. Activity is retained across isomers and fragments, which is what makes the mechanism purely physical rather than pharmacological [2]. Selectivity has been shown in vitro: no cytotoxicity to human keratinocytes was observed [4]. No human efficacy data exist.

Mechanism of action

Bind, collapse, select

  1. 01Bind

    The cationic peptide is drawn to the negatively charged bacterial membrane.

  2. 02Collapse

    The membrane is physically disrupted and pores form.

  3. 03Select

    The human cell membrane is neutral and is left untouched.

Membrane disruption confirmed by SEM and TEM [1]

    In a preclinical porcine wound model the peptides eradicated S. aureus infection (<10 CFU/g vs 4.3×10⁶ in controls, p<0.0001) and promoted re-epithelialisation. [1]
