OP-145 is a synthetic antimicrobial peptide (AMP) similar to the human cathelicidin LL-37. OP-145 consists of 24 amino acids and has demonstrated antibacterial and cytotoxic properties.
| Mechanism of Action | OP-145 interacts with phospholipids in bacterial and mammalian cell membranes leading to membrane thinning and permeabilization. |
| Spectrum | OP-145 is active against Staphylococcus aureus at 0.8-1.6 µM and may be effective against other Gram-positive bacteria. |
| Molecular Formula | C142H246N46O31 |
