Alkyl-substituted butyrolactones have both inhibitory and stimulatory effects on GABA(A) receptors. Lactones with small alkyl substitutions at the alpha-position positively modulate the channel, whereas beta-substituted lactones tend to inhibit the GABA(A) receptor. These compounds mediate inhibition through the picrotoxin site
