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 .

4-Amino-TEMPO-d17,15N

4-Amino-TEMPO-d₁₇, ¹⁵N (4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl-d₁₇, ¹⁵N) is the deuterium labeled 4-Amino-TEMPO-d₁₇ (HY-W002004S1). 4-Amino-TEMPO (4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl) is a stable nitroxide radical and N-nucleophile based on TEMPO. 4-Amino-TEMPO has superoxide dismutase-mimetic activity, can protect cells from oxidative damage, and has radioprotective effects. 4-Amino-TEMPO is widely used in fields such as biomedicine, materials science, and industrial production. 4-Amino-TEMPO can be used as a spin label to detect free radicals, an oxidation catalyst in industrial production, and an antioxidant stabilizer for polymers, among others .

HY-122984S1

Diquat-d12 dibromide 1

Diquat-d₁₂ dibromide 1 is the deuterium labeled Diquat dibromide (HY-122984). Diquat dibromide is a comprehensive herbicide. Diquat dibromide increases the production of ROS and triggers mitochondrial Autophagy. Diquat dibromide generates free radicals such as superoxide anions through redox cycles, which induce oxidative stress. Diquat dibromide is cytotoxic, reproductive, and neurotoxic. Diquat dibromide is used in cotton, soybean, and other crops to combat noxious weeds .
