BioAssay: AID 267291

Inhibition of isoguvacine-induced current in mouse cerebral cortical neurons expressing GABAA receptor by whole cell patch clamp method

Three 4-substituted 1,2,5-oxadiazol-3-ols containing aminoalkyl substituents (analogues and homologues of gamma-aminobutyric acid (GABA)) were synthesized to investigate the hydroxy-1,2,5-oxadiazolyl moiety as a bioisoster for a carboxyl group at GABA receptors. The pK(a) values of the target compounds were close to those of GABA. At GABA(A) receptors of cultured cerebral cortical neurons, weak agonist and partial agonist profiles were identified, demonstrating the 4-hydroxy-1,2,5-oxadiazol-3-yl unit to be a nonclassical carboxyl group bioisoster. ..more

Title: Hydroxy-1,2,5-oxadiazolyl moiety as bioisoster of the carboxy function. Synthesis, ionization constants, and pharmacological characterization of gamma-aminobutyric acid (GABA) related compounds.

Abstract: Three 4-substituted 1,2,5-oxadiazol-3-ols containing aminoalkyl substituents (analogues and homologues of gamma-aminobutyric acid (GABA)) were synthesized to investigate the hydroxy-1,2,5-oxadiazolyl moiety as a bioisoster for a carboxyl group at GABA receptors. The pK(a) values of the target compounds were close to those of GABA. At GABA(A) receptors of cultured cerebral cortical neurons, weak agonist and partial agonist profiles were identified, demonstrating the 4-hydroxy-1,2,5-oxadiazol-3-yl unit to be a nonclassical carboxyl group bioisoster.
