6487353 Hart JA, Haynes BP, Park BK: A study of factors which determine the pharmacological response to vitamin K in coumarin anticoagulated rabbits. Biochem Pharmacol. 1984 Oct 1;33(19):3013-9.

The pharmacological response to vitamin K has been determined by measuring prothrombin complex activity (P.C.A.) in male New Zealand White rabbits anticoagulated (P.C.A. less than 20%) with the long acting 4-hydroxycoumarin brodifacoum, at a dose (10 mg/kg) which produces maximum antagonism of vitamin K1.
Thus, according to current concepts, this animal model may be used to assess vitamin K requirements in the absence of a functional vitamin K-epoxide reductase.

Yet little detail is known about the molecular interactions between 4-hydroxycoumarins with vitamin K epoxide reductase (VKER), inhibition of which produces a deficiency of vitamin K and consequently a deficiency of vitamin K-dependent proteins involved in thrombus formation.
Ferulenol 19 confers approximately 22 times more potent inhibition than warfarin and is approximately 1.5 more potent than the rodenticide brodifacoum in this in vitro assay.

These assignments and conformational analyses may be useful in studies of biomolecular interactions of brodifacoum with target proteins such as VKOR and in source determination of brodifacoum.

Like other second-generation anticoagulants brodifacoum is strongly bound to vitamin K epoxide reductase and will persist, apparently for at least 6 months, in organs and tissue containing this enzyme, e.g., liver, kidney, and pancreas.

Addition of the vitamin K 2,3-epoxide reductase inhibitors warfarin (5 to 100 microM) and brodifacoum (1 to 5 microM) to normal rat hepatocyte cultures produced a slight increase in hydroxyvitamin K formation and a marked inhibition of vitamin K formation.
