Bostrycin, an anthraquinone derived from B. alpestre, exhibits a broad spectrum of biological activities including antibacterial, antiproliferative, and phytotoxic effects. This compound demonstrates efficacy against Gram-positive bacteria like methicillin-resistant S. aureus (MRSA), M. tuberculosis, and C. botulinum. Additionally, Bostrycin shows antiproliferative action against A549 lung adenocarcinoma cells, particularly by arresting the cell cycle at the G0 G1 phase and triggering apoptosis within a concentration range of 10 to 30 µM. As a phytotoxin, it causes necrosis in water hyacinth leaves at approximately 7 µg ml. Furthermore, Bostrycin serves as a protein immobilization cross-linking agent, managing to preserve its bacteriostatic properties when affixed to nonwoven polypropylene fabric.
