Inhibition of cholinesterases by fluoride in vitro.
1. Series of colorimetric dynamic assays allowed the study of the inhibition of cholinesterases by F(-) ions in vitro, by using, as sources of enzyme, whole human blood, human serum, homogenized rat brain and two preparations of red blood cells (human and bovine) whose enzymic purity was ascertained. 2. The first evidence of inhibition of human serum pseudocholinesterase by fluoride was noticed...
متن کاملThe inhibition of cholinesterases by pancuronium.
Pancuronium causes a powerful and highly selective inhibition of human serum cholinesterase in vitro. The inhibition was studied in serum from 14 individuals of both sexes (5-60 years of age) with normal reactions to suxamethonium. Pancuronium, in a concentration of 2.3 x 10(-7) M, caused a 50% inhibition of the enzymatic hydrolysis of acetylcholine, when this substrate was present in a concen...
متن کامل[Cholinesterases: structure, role, and inhibition].
Enzymes acetylcholinesterase (AChE; E.C. 3.1.1.7) and butyrylcholinesterase (BChE; E.C. 3.1.1.8) have intensively been investigated in biomedicine and toxicology due to important role in organisms. Even if structurally homologous, they differ in catalytic activity, specificity, for substrates, and selectivity in binding to many ligands. This paper compiles the results of research on cholinester...

15 صفحه اولIn vitro inhibition of cholinesterases by carbamates--a kinetic study.
Kinetics and mechanism of in vitro hydrolyses of acetylcholine and acetylthiocholine by carbamates were studied in a batch reactor at 25 degrees C, pH 8, and ionic strength of 0.11 M. Every hydrolysis was monitored by 3-4 independent methods. All studied hydrolyses can be described by the model of competitive inhibition with an irreversible step (k3). A table of obtained average values of rate ...
