Arcopilin A

Arcopilin A (compound Arcopilin A(1))is an antibacterial agent. Arcopilin A has weak inhibitory effects on fungal pathogens and Gram-positive bacteria, with IC50 values of 8.9 μg/mL and 14 μg/mL for cells KB-3-1 and L929, but it can effectively destroy preformed biofilms of Staphylococcus aureus. Arcopilin A can enhance the activities of gentamicin (GM; HY-K1050) and vancomycin (Vac; HY-B0671) by 115 and 31 times, respectively[1].
