Claramines: A New Class Of Broad-Spectrum Antimicrobial Agents With Bimodal Activity

International audienceThe emergence of multidrug resistant bacteria/pathogens has highlighted the need for the development of new antibiotics. In this manuscript, we report herein our results dealing with the broad spectrum of antibacterial activity against both sensitive and resistant Gram-negative and Gram-positive bacterial strains of an easily prepared water soluble polyaminosterol compound namely claramine A1. We will also demonstrate its peculiar mechanism of action (different from all the well-known classes of antibiotics) towards Gram-negative and Gram-positive bacteria. Finally, due to its low cytotoxicity, this class of molecules could constitute an effective response to combat the emergence of multidrug resistant bacteria and nosocomial diseases
