FOUR MAJOR TARGETS FOR DRUGS
... inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa. Often, the drug molecule is a substrate analogue (e.g. captopril, acting on angiotensin-converting enzyme) Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bo ...

Large Receptor Reserve for Cannabinoid Actions in the Central
... significant inhibition of radiotracer binding in the mouse brains, except at very high doses (10 mg/kg or greater, i.v.). By contrast, the CB1 antagonist SR 141716A (10 mg/kg, i.p.), completely abolished specific [131I]AM 281 binding. These experiments suggest that behavioral effects of cannabinoids ...

1 The Neuromuscular Junction: Pharmacology
... binding of ACh to its receptors at NMJ epitomises the general equation: A+RARAR*, with the ‘starred’ state of the agonist-receptor (AR) complex corresponding to the open-pore state of a ligand-gated ion channel. In fact, two antagonists were extremely important in the identification of the nicotin ...
