Amprolium-d₇ bromide hydrobromide

Amprolium-d7 (bromide hydrobromide) is the deuterated-labeled Amprolium (HY-B0937). Amprolium is a thiamine transporter inhibitor and antiparasitic agent with oral activity and blood-brain barrier penetration. Amprolium blocks thiamine transport at the blood-brain barrier and intestine, and competitively inhibits thiamine pyrophosphokinase, inducing thiamine pyrophosphate deficiency and impairing carbohydrate synthesis. Amprolium induces oxidative stress, alters antioxidant enzyme activity, and inhibits acetylcholinesterase (AchE) activity. Amprolium disrupts reproductive organs and gametogenesis, and causes histopathological and ultrastructural damage to multiple organs. Amprolium induces thiamine deficiency, reduces body weight gain in mice, and causes psychomotor behavioral changes and nephropathy. Amprolium exhibits molluscicidal activity against the terrestrial snail Eobania vermiculata, and reduces the shedding of Eimeria meleagrimitis oocysts in feces and litter. Amprolium can be used for research on thiamine deficiency and coccidiosis.
