Drug
A drug, broadly speaking, is any substance that, when absorbed into the body of a living organism, alters normal bodily function. There is no single, precise definition, as there are different meanings in drug control law, government regulations, medicine, and colloquial usage.In pharmacology, a...
s which act as positive allosteric modulator
Positive allosteric modulator
A positive allosteric modulator is a drug which increases the activity of a receptor indirectly via activation of an allosteric site on the protein. PAMs are similar to agonists in that they contribute to overall receptor activation, but they are different because they do so in a functionally...
s of the GABAA receptor at the barbiturate
Barbiturate
Barbiturates are drugs that act as central nervous system depressants, and can therefore produce a wide spectrum of effects, from mild sedation to total anesthesia. They are also effective as anxiolytics, as hypnotics, and as anticonvulsants...
binding site
Binding site
In biochemistry, a binding site is a region on a protein, DNA, or RNA to which specific other molecules and ions—in this context collectively called ligands—form a chemical bond...
. They include the following compounds:
- CartazolateCartazolateCartazolate is a drug of the pyrazolopyridine class. It acts as a GABAA receptor positive allosteric modulator at the barbiturate binding site of the complex and has anxiolytic effects in animals. It is also known to act as an adenosine antagonist at the A1 and A2 subtypes and as a...
(SQ-65,396) - EtazolateEtazolateEtazolate is an anxiolytic drug which is a pyrazolopyridine derivative and has unique pharmacological properties. It acts as a positive allosteric modulator of the GABAA receptor at the barbiturate binding site, as an adenosine antagonist of the A1 and A2 subtypes, and as a phosphodiesterase...
(SQ-20,009) - ICI-190,622ICI-190,622ICI-190,622 is an anxiolytic drug used in scientific research. It is a pyrazolopyridine derivative, related to other anxiolytic compounds such as tracazolate, and more distantly to zaleplon. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a...
- TracazolateTracazolateTracazolate is an anxiolytic drug which is used in scientific research. It is a pyrazolopyridine derivative, most closely related to pyrazolopyrimidine drugs such as zaleplon, and is one of a structurally diverse group of drugs known as the nonbenzodiazepines which act at the same receptor targets...
