Pexiganan
Based on 1 Customer Validation
Pexiganan (MSI 78) is an orally active antimicrobial peptide with broad-spectrum bactericidal. Pexiganan disrupts bacterial cell membranes, induces peptidoglycan damage and cell lysis. Pexiganan TFA can be used for the research of bacterial infection.

生物活性
Pexiganan (1-256 µg/mL; 24 h) exhibits comparable bactericidal activity against planktonic Staphylococcus aureus Z25.2, Pseudomonas aeruginosa Z25.1, and their dual-species cultures[1].
Pexiganan (1-256 µg/mL; 24 h) is more effective at inhibiting and eradicating Staphylococcus aureus Z25.2 biofilms than Pseudomonas aeruginosa Z25.1 or dual-species biofilms[1].
Pexiganan (7-35 μM) binds to purified bovine type I collagen with a dissociation constant of 34.01 μM[3].
Pexiganan (5-80 μg/mL; overnight) inhibits the growth of Pseudomonas aeruginosa and Staphylococcus aureus[3].
Pexiganan (40 μg/mL; 0-60 min) rapidly reduces viable counts of Pseudomonas aeruginosa (ATCC27853) and Staphylococcus aureus (ATCC29213) over 60 min, with complete elimination of P. aeruginosa by 60 min[3].
Pexiganan (10-50 μg/mL) exhibits no cytotoxicity toward rat fibroblast cells in in vitro MTT assays[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Pexiganan (1 mg/kg; i.p.; single dose) reduces lethality, and intra-abdominal bacterial counts in E. coli-induced septic shock in male Wistar rats[4].
Pexiganan (1 mg/kg; i.p.; single dose) reduces lethality, and intra-abdominal bacterial counts in in cecal ligation and puncture-induced septic shock in male Wistar rats[4].
Pexiganan (1 mg/kg; i.p.; single dose) is well-tolerated with no detectable adverse effects or physiological changes in healthy male Wistar rats[4].
