A series of bioisosteric 4-(aminomethyl)-1-hydroxypyrazole (4-AHP) analogues of muscimol, a GABAA receptor agonist, has been synthesized and pharmacologically characterized at native and selected recombinant GABAA receptors. The unsubstituted 4-AHP analogue (2a) (EC50 19 μM, Rmax 69%) was a moderately potent agonist at human α1β2γ2 GABAA receptors, and in SAR studies substitutions in the 3- and/or

Halogenated analogues of the neurotoxic alkaloid muscimol were prepared with fluorine, iodine or trifluoromethyl at the 4 position of the isoxazole ring system. These compounds were investigated as agonists for GABAA receptors. Only the C‐4 fluorine‐containing analogue proved to be an active compound in these assays. The fluoro analogue was less active than muscimol, however it showed differential
