Allopregnanolone has also been found to act as a positive allosteric modulator of the GABA A-ρ receptor, though the implications of this action are unclear. [ 36 ] [ 37 ] In addition to its actions on GABA receptors, allopregnanolone, like progesterone, is known to be a negative allosteric modulator of nACh receptors , [ 38 ] and also appears ...

In pharmacology, GABA A receptor positive allosteric modulators, also known as GABAkines or GABA A receptor potentiators, [1] are positive allosteric modulator (PAM) molecules that increase the activity of the GABA A receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system.
Allosteric regulation of an enzyme. In the fields of biochemistry and pharmacology an allosteric regulator (or allosteric modulator) is a substance that binds to a site on an enzyme or receptor distinct from the active site, resulting in a conformational change that alters the protein's activity, either enhancing or inhibiting its function.
The ionotropic GABA A receptor protein complex is also the molecular target of the benzodiazepine class of tranquilizer drugs. Benzodiazepines do not bind to the same receptor site on the protein complex as does the endogenous ligand GABA (whose binding site is located between α- and β-subunits), but bind to distinct benzodiazepine binding sites situated at the interface between the α- and ...
The site that an allosteric modulator binds to (i.e., an allosteric site) is not the same one to which an endogenous agonist of the receptor would bind (i.e., an orthosteric site). Modulators and agonists can both be called receptor ligands. [2] Allosteric modulators can be 1 of 3 types either: positive, negative or neutral.
In some people, this state change can increase suicidal tendencies, especially in those under age 25 and during the initial weeks of treatment. [2] SSRI-induced activation syndrome is well-accepted by clinicians. [3] It is unclear whether jitteriness/anxiety syndrome predicts either good or poor prognosis (level D). [4]
Basimglurant (developmental code names RG-7090, RO-4917523) is a negative allosteric modulator of the mGlu 5 receptor which is under development by Roche and Chugai Pharmaceutical for the treatment of treatment-resistant depression (as an adjunct) and fragile X syndrome.
