Description

Pexiganan (MSI 78 free base) is a synthetic analog of magainin 2. Pexiganan is a potent and orally active broad-spectrum antimicrobial peptide. Pexiganan can be used in the research of infections, such as diabetic foot ulcer infections[1].

In Vitro

Pexiganan (MIC: 0-128 μg/mL approximately) shows broad-spectrum antibacterial activity against 3,109 clinical isolates of gram-positive and gram-negative, anaerobic and aerobic bacteria[2].
Pexiganan (4 μg/mL) inhibits gastric ulcer strain and gastric cancer strain[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
