Boscalid-d4 is the deuterium labeled Boscalid. Boscalid is a succinate dehydrogenase (SDHI) inhibitor with antifungal activity. Boscalid binds to the ubiquinone-binding site of fungal mitochondrial complex II, blocks ATP production and aerobic respiration, exhibits good control efficacy against a variety of plant fungal diseases including gray mold, sclerotinia rot and powdery mildew, and is widely used for disease control in agriculture. Boscalid induces apoptosis, altered lipid metabolism, mitochondrial dysfunction, respiratory impairment, oxidative stress, ROS accumulation and neurodevelopmental disorders in zebrafish. Boscalid reduces foraging ability, shortens median death time and causes chronic toxicity in exposed honeybees. Boscalid also possesses genotoxicity, cytotoxicity, elevated mitochondrial superoxide levels and early-stage apoptosis[1][2].
