antagonist inhibition
1competitive inhibition — inhibition of enzyme activity in which the inhibitor (substrate analogue) reversibly combines with catalytic sites, thus competing with the substrate for binding on the enzyme. The inhibition is reversible since it can be overcome by increasing… …
2noncompetitive inhibition — inhibition of enzyme activity by a substance that combines with the enzyme at a site other than that utilized by the substrate, causing a change in enzyme configuration and a decrease in activity. Similarly, the inhibition of a hormone or… …
3Receptor antagonist — This article is about the biochemistry term. For other uses, see Antagonist (disambiguation). Antagonists will block the binding of an agonist at a receptor molecule, inhibiting the signal produced by a receptor agonist coupling. A receptor… …
4NK1 receptor antagonist — Neurokinin 1 (NK1) antagonists are a novel class of medications that possesses unique antidepressant,[1] anxiolytic,[2] and antiemetic properties. The discovery of neurokinin 1 (NK1) receptor antagonists was a turning point in the prevention of… …
5Cholecystokinin antagonist — A Cholecystokinin antagonist is a specific type of receptor antagonist which blocks the receptor sites for the peptide hormone Cholecystokinin (CCK). There are two subtypes of this receptor known at present, defined as CCKA and CCKB (also called… …
6Dopamine antagonist — Skeletal formula of clozapine, the first atypical antipsychotic, a dopamine antagonist. A dopamine antagonist is a drug which blocks dopamine receptors by receptor antagonism. There are five known types of dopamine receptors in the human body;… …
7Muscarinic antagonist — In neurochemistry, a muscarinic receptor antagonist is an agent that reduces the activity of the muscarinic acetylcholine receptor. Acetylcholine (often abbreviated ACh) is a neurotransmitter, whose receptor is a protein found in synapses and… …
8Korezeptor-Antagonist — Entry Inhibitoren sind Arzneistoffe aus der Gruppe der Virostatika. Sie inhibitieren (unterbrechen) den Eintritt des Virus in die Wirtszelle. Es gibt drei Schlüsselstellen im Eintrittsvorgang an denen Entry Inhibitoren ansetzen[1]: Bindung des… …
95-HT3 antagonist — 5 HT3 receptor antagonists Drug class Skeletal formula of ondansetron, the prototypical 5 HT3 antagonist ATC code A04AA …
10NMDA receptor antagonist — Ketamine, one of the most common NMDA receptor antagonists. NMDA receptor antagonists are a class of anesthetics that work to antagonize, or inhibit the action of, the N methyl d aspartate receptor (NMDAR). They are used as anesthesia for animals …
