Alone of the known neurotransmitters, GABA is an electroneutral zwitterion (pI = 7.3) at physiological pH. This confers the highest probability of successfully traversing densely packed synaptic gaps without interacting electrostatically with charged entities enroute, making GABA a high fidelity

Three 4-substituted 1,2,5-oxadiazol-3-ols containing aminoalkyl substituents (analogues and homologues of gamma-aminobutyric acid (GABA)) were synthesized to investigate the hydroxy-1,2,5-oxadiazolyl moiety as a bioisoster for a carboxyl group at GABA receptors. The pK(a) values of the target compounds were close to

Drugs used to treat various disorders target GABA A receptors. To develop alpha subunit selective compounds, we synthesized 5-(4-piperidyl)-3-isoxazolol (4-PIOL) derivatives. The 3-isoxazolol moiety was substituted by 1,3,5-oxadiazol-2-one, 1,3,5-oxadiazol-2-thione, and substituted 1,2,4-triazol-3-ol heterocycles with modifications to the basic piperidine substituent
