Difethialone

Difethialone is an anticoagulant rodenticide and a vitamin K antagonist. It binds to vitamin K epoxide reductase (VKOR, Kis = 0.04 and 0.05 µM for the wild-type and VKORY139F enzyme, respectively). Difethialone is toxic to mice (LD50 = 1.29 mg/kg). Formulations containing difethialone have been used in the control of rodent pest populations.Formal Name: 3-[3-(4'-bromo[1,1'-biphenyl]-4-yl)-1,2,3,4-tetrahydro-1-naphthalenyl]-4-hydroxy-2H-1-benzothiopyran-2-one.
