  Central nervous system injury treatment with opiate-receptor antagonist - Patent 5025018
The present invention involves methods of inducing opiate-receptor antagonistic activity in a patient suffering from ischemic or traumatic central nervous system injury by administering to said patient an effective amount of an opiate-receptor antagonist having enhanced activity at the kappa-opiate receptor suitable to permit the induction of opiate-receptor antogonistic activity.

  Antagonist | Encyclopedia of Drugs and Addictive Behavior
As the concentration of antagonist is increased, the binding of the agonist is progressively inhibited, resulting in a decrease in the physiological response.
A competitive antagonist, therefore, shifts the dose-response relationship for the agonist to the right, so that an increased concentration of the agonist in the presence of a competitive antagonist is required to produce the same biological response observed in the absence of the antagonist.
In this case, the binding of the antagonist to the receptor (its affinity) may be so strong that the receptor is unavailable for binding by the agonist.

  Antagonist - Wikipedia, the free encyclopedia
An antagonist is a character or group of characters, or, sometimes an institution of a story who represents the opposition against which the heroes and/or protagonists must contend.
Note that the antagonist is not necessarily human; often, the forces of nature or psychological elements provide this element of opposition.
For instance, in the story of Moby-Dick by Herman Melville, the antagonist may be regarded as the whale "Moby Dick" of the title, against which the story's leading character Captain Ahab strives.

 Church Antagonists: Can’t Live With Them, Can Live Without Them
Antagonists, although few in number, have the potential for disproportionately disrupting or destroying the ministry of any congregation, as well as the peace of mind and well-being of everyone in the congregation.
Antagonists sometimes pester church leaders by constantly calling on the phone or by hanging around after a service or a meeting, saying, “I’djust like a brief word with you.” Their constant pestering substantiates the tenacious character of an antagonist.
A single antagonist in a congregation can so affect the pastor and church leaders that they expend what seems to be 90 percent of their time and energy dealing with that person and the havoc he raises.

 He Wrote, She Wrote: How to Write» Blog Archive » SHE WROTE: Protagonist and Antagonist
Your antagonist is the character who shapes the plot, the most important person in the conflict, the character who makes the reader worry and keeps her turning the page.
The antagonist must be strong and active, somebody the reader fears will defeat the protagonist, and while you’re at it, make the antagonist just as compelling as the protagonist, just as fascinating to read, just as smart, just as funny, just as good at what he does.
For instance, if you’ve got a scene with the book’s antagonist as the POV character, you might consider him to the protagonist for the course of that scene (and that’s a good reminder that the antagonist is the protagonist in his own mind).

 BioMed Central | Full text | Construction, purification, and characterization of a chimeric TH1 antagonist
Shift in mobility of TH1 antagonist between non-reducing and reduced eletrophoretic conditions is in correspondence with what has been reported for the soluble IFNGR [29] and for several other receptors [30,31] and is consistent with a more compact structure of folded protein.
The biological activity of the TH1 antagonist protein was tested in vitro in an assay examining the capacity of the molecule to inhibit the proliferation of T cells in response to rhu IL-2.
We were able to construct and purified a recombinant chimeric antagonist composed by a 60 amino acid fragment of the N-terminal region of human IL-2 fused to the N-terminal of the extracellular region of the alpha subunit of the gamma IFN-γ receptor was obtained.

 NCADI: Naltrexone And Alcoholism Treatment
Nalorphine was approved in 1951 for reversing the adverse and life-threatening effects of opiate overdose as well as for preventing narcotic-induced respiratory depression in obstetric cases and for diagnosing narcotic addiction (Gamage and Zerkin, 1973).
The theoretical basis for using opioid antagonists in the treatment of opiate dependence originated with the operant-conditioning formulations and experiments of Wikler and colleagues, beginning in the 1940s and continuing through the 1960s (e.g., Wikler, 1948; Wikler and Pescor, 1967).
Cyclazocine--a benzomorphan derivative--was found to be orally effective and to have relatively long-acting opioid antagonistic effects, but a number of clinical trials during the 1960s were only partially successful in retaining patients because the medication also produced dysphoria as well as some withdrawal symptoms upon termination (Jaffe, 1967).

 BioMed Central | Full text | A selective cyclic integrin antagonist blocks the integrin receptors alphavbeta3and ...
The effect of the cyclic integrin antagonist on RPE cell attachment onto different extracellular matrices (laminin, collagen IV, fibronectin), RPE cell invasion stimulated by PDGF-BB or serum, and migration stimulated by PDGF-BB, vascular endothelial growth factor (VEGF) or serum was explored.
The cyclic integrin antagonist was added directly to the upper part of the chamber (0.001 ng/ml, 0.01 ng/ml, 0.1 ng/ml, 1 ng/ml, 3 ng/ml, or 10 ng/ml).
Furthermore, a lack of toxicity for the integrin antagonist and the control peptide in the concentration range tested (0.01 μg/ml, 0.1 μg/ml, 1 μg/ml, 30 μg/ml and 300 μg/ml) was determined by use of the trypan blue exclusion assay (data not shown).

 Marijuana Antagonist Reveals Evidence of THC Dependence in Rats
The marijuana antagonist appears to act like an on-off switch, allowing researchers to control the effects of withdrawal from delta-9-tetrahydrocannabinol (THC), the principal psychoactive ingredient of marijuana.
During his research, rats were exposed to THC for 4 days, then given a dose of the THC antagonist SR 141716A, which was developed by French scientists last year.
Within 10 minutes after administration of the marijuana antagonist, the rats exhibited behavior that included "wet-dog shakes" and facial rubbing, which constitute "definite evidence of withdrawal" from the effects of THC, said Dr. Martin.

 Doseresponse curves in the presence of antagonists
When investigating an antagonist the first thing to check is whether the antagonism is surmountable by increasing the concentration of agonist.
Investigations of antagonists that are not surmountable or reversible are beyond the scope of this manual.
If concentration A of agonist gives a certain response in the absence of antagonist, but concentration A' is needed to achieve the same response in the presence of a certain concentration of antagonist, then the dose-ratio equals A'/A. You'll get a different dose ratio if you use a different concentration of antagonist.

 Addiction Science Network: Agonists and Antagonists
Two examples are presented for illustrating the classification of drugs as agonists and antagonists.
An antagonist is a ligand that binds to a receptor but does not produce a biological effect (direct acting) or a compound that indirectly inhibits the effect of a neurotransmitter (indirect acting).
(It has the physiological/behavioral effect of an antagonist at most doses, but it's still technically an agonist!) Carlson confuses his classification of clonidine by classifying it as an agonist on one table and as an antagonist on another -- it is an agonist with antagonistic actions.
