MDP1 acetate
Based on 1 Customer Validation
MDP1 acetate, a Melittin-derived peptide, alters the integrity of both Gram-positive and Gram-negative bacterial membranes and kills the bacteria via membrane damages. MDP1 acetate has a high-antibacterial activity against multidrug resistant (MDR) and reference strains of S. aureus, E. coli, and P. aeruginosa.

Biological Activity
MDP1 acetate exhibits more potent antibacterial activities against S. aureus, E. coli and P. aeruginosa.
Geometric means of MICs for MDP1 is recorded at 4.06 μg/mL (S. aureus), 1.22 μg/mL (E. coli) and 3.75 μg/mL (P. aeruginosa), respectively[1].
DNA and calcein release and flow cytometry assays indicate a time-dependent antibacterial activity on the examined bacteria affected by MDP1 (10, 5, 2.5, 1.25, 0.625 and 0.312 μg/mL) acetate. Finally, SEM analyses highlights dose- and time-dependent effects of MDP1 acetate on S. aureus and E. coli bacteria by induction of vesicle or pore formation as well as cell lysis[1].
