A novel antibacteria metabolite, ARK42, was isolated from a xerophilic fungal strain K42, and identified as Aspergillus repens based on its morphological characteristics. The metabolite exhibited antibacterial activities towards Staphylococcus aureus, Bacillus cereus, and Pseudomonas aeruginosa, with MICs of 25, 12.5, and 3.125 μg/ml, respectively, and killed Pseudomonas aeruginosa with minimal bactericidal concentration (MBC) of 12.5 μg/ml. Furthermore, anticancer activities were demonstrated against human colon cancer DLD-1 and lung cancer LXFL529 cells with an IC50 of 10 and 1 μg/ml, respectively.
