Drugs used to treat various disorders target GABAA receptors. To develop R 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 as well as substituents without basic nitrogen. Compounds
were screened by [3
