Cat. No.: HY-P1674A Purity: 99.83%
COA Handling Instructions

Murepavadin (POL7080) (TFA), a 14-amino-acid cyclic peptide, is a highly potent, specific antibiotic. Murepavadin exhibits a potent antimicrobial activity for P. aeruginosa with MIC50 and MIC90 values both of 0.12 mg/L. Murepavadin also can target the lipopolysaccharide transport portin D. Murepavadin can be used for the research of bacterial resistance.

For research use only. We do not sell to patients.

Description

Murepavadin (POL7080) (TFA), a 14-amino-acid cyclic peptide, is a highly potent, specific antibiotic. Murepavadin exhibits a potent antimicrobial activity for P. aeruginosa with MIC50 and MIC90 values both of 0.12 mg/L. Murepavadin also can target the lipopolysaccharide transport portin D. Murepavadin can be used for the research of bacterial resistance[1][2].

IC50 & Target

MIC50: 0.12 mg/L(P. aeruginosa)[2] MIC90: 0.12 mg/L(P. aeruginosa)[2] IC50: 5.84 μM (gentamicin)[2]

In Vitro

Murepavadin has activity against P. aeruginosa with MIC50 and MIC90 values both of 0.12 mg/L[2].
Murepavadin inhibits megalin-mediated uptake of gentamicin in vitro with an IC50 value of 5.84 μM[2].

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

In Vivo

Murepavadin (s.c.; 0-100mg/kg) is active in pre-clinical animal models including infections with XDR isolates[2].

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

Animal Model: Murine models of P. aeruginosa infection[2]
Dosage: 0-100 mg/kg
Administration: Subcutaneous, q24h or q12h
Result: Resulted in an increase in survival rate to 100% and showed significantly lower CFU levels both in the blood and in the peritoneal fluid at 2 and 10 mg/kg 1 h post-infection.
Animal Model: Mouse, rat, rabbit, and monkey[2]
Dosage: 0-5 mg/kg
Administration: Intraperitoneal or subcutaneous, single
Result: Followed a two-compartment model following intravenous administration and decline of plasma concentrations.
Distributed into the aqueous phase of the body, and systemic plasma clearance (CL) values were similar to the species-specific glomerular filtration rates (GFRs) .
Had high bioavailability (67.79%) after subcutaneous (s.c.) administration in rats but had low oral bioavailability (<0.01%).
Had a linear relationship between ELF AUC and unbound plasma AUC in mouse.
Did not readily cross the blood/brain barrier.

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.
