Receptor antagonist - Wikipedia
WebA receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. Antagonist drugs interfere in the natural operation of receptor proteins. [1]
NMDA receptor antagonist - Wikipedia
WebNMDA receptor antagonists are a class of drugs that work to antagonize, or inhibit the action of, the N -Methyl- D -aspartate receptor ( NMDAR ). They are commonly used as anesthetics for humans and non-human animals; the state of anesthesia they induce is referred to as dissociative anesthesia.
H2 receptor antagonist - Wikipedia
Webreceptor antagonist. H2 antagonists, sometimes referred to as H2RAs [1] and also called H2 blockers, are a class of medications that block the action of histamine at the histamine H 2 receptors of the parietal cells in the stomach. …
Receptor antagonist - Simple English Wikipedia, the free …
WebA receptor antagonist slows down the cell by stopping some of the cell reactions by clogging up the areas that make the cell work. They are sometimes called blockers, such as beta blockers. An antagonist is a ligand which blocks or dampens a biological effect. It acts against an agonist.
Adrenergic antagonist - Wikipedia
WebAdrenergic antagonist. Visual definition of an antagonist, where it compared to agonists and reverse agonists. An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors. There are five adrenergic receptors, which are divided into two groups. The first group of receptors are the beta (β) adrenergic receptors.
Receptor Antagonist - an overview | ScienceDirect Topics
WebA receptor antagonist is a drug or receptor ligand that deactivates the receptor’s response by binding to it. Such antagonism activity of the drug can protect the neuronal cells from chemical-driven toxicity.
Adenosine receptor antagonist - Wikipedia
WebAn adenosine receptor antagonist is a drug which acts as an antagonist of one or more of the adenosine receptors. The best known are xanthines and their derivatives (natural: caffeine , [2] theophylline , [3] and theobromine ; and synthetic: PSB-1901 [4] ), but there are also non-xanthine representatives (e.g. ISAM-140 , [5] ISAM-R316, [6 ...
Vasopressin receptor antagonist - Wikipedia
WebA vasopressin receptor antagonist (VRA) is an agent that interferes with action at the vasopressin receptors. Most commonly VRAs are used in the treatment of hyponatremia, especially in patients with congestive heart failure, liver cirrhosis or SIADH.

WebReceptor Antagonist. This can result in receptor antagonist activity by the antibody binding to a tumor cell surface receptor, in which case it can prevent receptor dimerization and inactivate kinase activity and downstream signaling, all of which can ultimately lead to reduced proliferation, disruption of target tumor-associated vasculature ...
