Activity of arginine-phenylalanine and arginine-tryptophan-based surfactants against .

This study aimed to evaluate the antibacterial effect of two new cationic surfactants based on phenylalanine-arginine (LPAM) and tryptophan-arginine (LTAM). Antibacterial activity, mechanism of action and interactions with enzymes were measured through microbiological, flow cytometry and molecular docking assays, respectively. These compounds showed antibacterial activity in the range of 4.
