Résumé
Antimicrobial resistance is an increasingly life-threatening problem that emphasizes the need to develop new antibacterial agents. The in vitro antibacterial activity of squalamine, a natural aminosterol, has been previously demonstrated against multidrug-resistant bacteria and moulds. Although the antibacterial activity of squalamine was found to correlate with that of other drugs, such as colistin, against Gram-negative bacteria, the former was active against Gram-positive bacteria, which are resistant to colistin. In this work, we provide new insights into squalamine’s antibacterial mechanism of action compared with other known antibiotics.
