    anyone know what this might tell me about my brain chemistry?

    Abstract

    The potencies of two GABAB receptor antagonists P-[3-aminopropyl]-P-diethoxymethyl-phosphinic acid (CGP35348) and the novel compound 3-N[1-(S)-(3,4-dichlorophenyl)ethyl]amino-2-(S)-hydroxypropyl-P-benzyl-phosphinic acid (CGP55845) have been compared in an in vitro spinal cord preparation. They have been tested as antagonists of baclofen-induced depression of EPSCs of patch-clamped dorsal horn neurones following electrical stimulation of dorsal roots. Mean EC50 values for the depressant action of baclofen were increased by 50- and 140-fold respectively in the presence of CGP35348 (200 ?M) (n = 5) and CGP55845 (100 nM) (n = 4). This potency of CGP55845 is > 1000-fold higher than that reported previously for other GABAB receptor antagonists.
