Metabolically, succinyl- semialdehyde is involved in its namesake shunt, which forms succinate from 2-ketoglutarate, but its transport can be blocked by TBOA.  
L-655,708 is a selective inverse agonist for this molecule's receptor, and an extracellular application of this molecule decreases the power of gamma oscillations, but not in alpha-5 knock-outs.  Metabolically, succinyl- semialdehyde is involved in its namesake shunt, which forms succinate from 2-ketoglutarate, but its transport can be blocked by TBOA.  THIP is selective for the benzodiazepine-sensitive delta subunit of this molecule's receptor, which can be antagonized by picrotoxin and bicuculline.  Serving a physiological role similar to glycine in the nervous system, its competitive agonists like muscimol serve as anxiolytics.  FTP name this molecule synthesized from glutamate, a common inhibitory neurotransmitter that has a four-letter acronym.
