Gabaculine is an irreversible inhibitor of GABAtransaminase (GABA-T; Ki: 2.9 μM). Gabaculine alters plastid development and differentially affects the abundance of plastid-encoded DPOR and nuclear-encoded GluTR.
γ-Acetylenic GABA (4-Aminohex-5-ynoic acid) is a potent, irreversible inhibitor of GABA-transaminase. This compound effectively raises the concentration of γ-Aminobutyric acid (GABA) in the brain of rats.
