摘要

The R- and S-enantiomers of 4-amino-3-hydroxybutanoic acid (GABOB) were full agonists at human recombinant rho1 GABA(C) receptors. Their enantioselectivity (R>S) matched that reported for their agonist actions at GABA(B) receptors, but was the opposite to that reported at GABA(A) receptors (S>R). The corresponding methylphosphinic acid analogues proved to be rho1 GABA(C) receptor antagonists with R(+)-CGP44533 being more potent than S(-)-CGP44532, thus showing the opposite enantioselectivity to the agonists R(-)- and S(+)-GABOB. These studies highlight the different stereochemical requirements for the hydroxy group in these analogues at GABA(A), GABA(B) and GABA(C) receptors.
