More potent warfarin derivatives, called [https://en.wikipedia.org/wiki/Superwarfarin superwarfarins], are used as rodenticides. The duration of one superwarfarin, [https://en.wikipedia.org/wiki/Brodifacoum brodifacoum], has been reported as 15-30 days <ref name="Chong">PMID:31857739</ref> vs. the clinical warfarin duration of 2-5 days<ref name="Patel">PMID:29261922</ref>. Superwarfarins have bulkier side chains that allow them to stay bound to VKOR for long periods of time, causing prolonged and uncontrolled bleeding<ref name="Chong">PMID:31857739</ref>. The <scene name='90/904330/Brodifacoumb/5'>enhanced binding</scene> is due to interactions between the bulky side chains and the hydrophobic residues of VKOR's binding pocket, as shown in brodifacoum.
