Militarine is a plant growth inhibitor and anti-inflammatory agent. Militarine inhibits the elongation of radicles and hypocotyls in seedlings of lettuce, Italian ryegrass and timothy grass. Militarine alleviates PM_2.5-induced inflammatory injury and inhibits cell migration in human alveolar epithelial A549 cells by inhibiting the NF-κB signaling pathway, reducing oxidative stress and the release of inflammatory factors. Militarine can be used in studies related to PM_2.5-induced pulmonary diseases.
