Gabaculine is a naturally occurring neurotoxin first isolated from the bacteria Streptomyces toyacaensis,[1] which acts as a potent and irreversible GABA transaminase inhibitor,[2][3] and also a GABA reuptake inhibitor.[4][5] Gabaculine is also known as 3-Amino-2,3-dihydrobenzoic acid hydrochloride.
