The biotransformation and disposition of 3-chloro-4-methyl-(4-14C)-7-hydroxycoumarin [(14C) chlorferron] were investigated in rats after single oral administration. Following administration of (14C) chlorferron at 0.5 and 20 mg/kg body weight to male rats, greater than 90% of the given dose was eliminated

Chlorferon and diethylthiophosphate (DETP) are the hydrolysis products of coumaphos, an organophosphate pesticide. In this research, two consortia of bacterial cultures, one responsible for degrading chlorferon and the other for degrading DETP, were selectively enriched from waste cattle dip solution.

Inhibition of recombinant mouse wild type AChE (EC 3.1.1.7) and BChE (EC 3.1.1.8), and AChE peripheral site-directed mutants and human serum BChE variants by 4,4'-bipyridine (4,4'-BP) and the coumarin derivative 3-chloro-7-hydroxy-4-methylcoumarin (CHMC) was studied. The enzyme activity was measured with
