3-aminopropylphosphonic acid (3-APPA) is a phosphonic analog of GABA that acts as a partial agonist of GABAB receptors (IC50 = 1.5 μM in a radioligand binding assay).

Description | 3-aminopropylphosphonic acid (3-APPA) is a phosphonic analog of GABA that acts as a partial agonist of GABAB receptors (IC50 = 1.5 μM in a radioligand binding assay). |
In vitro | 3-aminopropylphosphonic acid (IC50 1.5 microM) and 4-aminobutyl-phosphonic acid (IC50 3.9 μM) were much more potent than anticipated from their relatively weak GABAB antagonist actions [1]. 3-aminopropylphosphonic acid was a potent inhibitor (IC50 6μM) of the binding of [3H]GABA to rat brain membranes under GABAB conditions, i.e. in the presence of 0.1 mM isoguvacine and displaceable by 0.1 mM (+)-baclofen [1]. |
In vivo | 3-aminopropylphosphonic acid induces relaxation in unstimulated isolated guinea pig ileum longitudinal muscle and reverses GABA- and baclofen-induced inhibition of twitch responses in isolated guinea pig ileum longitudinal muscle. 3-APPA (5 mg/kg) completely inhibits GABA- and baclofen-induced inhibition of vagally stimulated bronchospasms in guinea pigs. It also reverses the antitussive effect of baclofen in cats when administered at a dose of 3 mg/kg. |
