Neurosteroid analogues. 12. Potent enhancement of GABA-mediated chloride currents at GABAA receptors by ent-androgens.
Eur. J. Med. Chem. 43 , 107-13, (2008) Allopregnanolone (1) and pregnanolone (2), steroids containing a 17beta-acetyl group, are potent enhancers of GABA (gamma-aminobutyric acid) action at GABAA receptors. Their effects are enantioselective with the non-naturally occurring enantiomers (ent-1 and ... |

Synthesis and GABAAreceptor activity of A-homo analogues of neuroactive steroids
Eur. J. Med. Chem. 45 , 3063-9, (2010) A procedure is described for the preparation of A-homo-5-pregnenes via an acid catalyzed rearrangement of cyclopropylcarbinols assisted by microwave irradiation. 3α-Hydroxy and 4α-hydroxy-A-homo-5-pregnen-20-one, analogues of the neuroactive steroid allopregn... |

Low tolerance and dependence liabilities of etizolam: molecular, functional, and pharmacological correlates.
Eur. J. Pharmacol. 519(1-2) , 31-42, (2005) The effects of prolonged exposure to and subsequent withdrawal of the thienotriazolobenzodiazepine etizolam on gamma-aminobutyric acid (GABA) type A receptor gene expression and function were compared with those of the benzodiazepine lorazepam. Exposure of ra... |

Enantioselectivity of alpha-benzyl-alpha-methyl-gamma-butyrolactone-mediated modulation of anticonvulsant activity and GABA(A) receptor function.
J. Pharmacol. Exp. Ther. 309(2) , 677-83, (2004) 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) re... |

Influences on blockade by t-butylbicyclo-phosphoro-thionate of GABA(A) receptor spontaneous gating, agonist activation and desensitization.
J. Physiol. 590(Pt 1) , 163-78, (2012) Picrotoxin and t-butylbicyclophosphorothionate (TBPS) are GABA(A) receptor (GABA(A)R) open channel blockers. However, picrotoxin displaceable [(35)S]TBPS binding to α1β2γ2 GABA(A)Rs occurs in the absence of GABA, suggesting that access to the binding site is ... |

A synthetic 18-norsteroid distinguishes between two neuroactive steroid binding sites on GABAA receptors.
J. Pharmacol. Exp. Ther. 333(2) , 404-13, (2010) In the absence of GABA, neuroactive steroids that enhance GABA-mediated currents modulate binding of [35S]t-butylbicyclophosphorothionate in a biphasic manner, with enhancement of binding at low concentrations (site NS1) and inhibition at higher concentration... |

Brain regional heterogeneity of pH effects on GABA(A) receptor-associated [35s]TBPS binding.
Neurochem. Res. 29(4) , 771-80, (2004) We have utilized quantitative autoradiography with the GABA(A) receptor chloride channel blocker [35S]t-butylbicyclophosphorothionate ([35S]TBPS) in rodent brain sections to investigate if differential proton modulation of various GABA(A) receptor subtypes ex... |

Normalization of GABAA receptor specific binding in the substantia nigra reticulata and the prevention of L-dopa-induced dyskinesias in MPTP parkinsonian monkeys.
Synapse 62(2) , 101-9, (2008) L-Dopa therapy in Parkinson's disease (PD) is counfounded by the development of involuntary movements such as L-Dopa-induced dyskinesias (LIDs). In this study GABA(A) receptor autoradiography was assessed using [(3)H]flunitrazepam binding to the benzodiazepin... |

High affinity central benzodiazepine receptor ligands. Part 3: insights into the pharmacophore and pattern recognition study of intrinsic activities of pyrazolo[4,3-c]quinolin-3-ones.
Bioorg. Med. Chem. 11(23) , 5259-72, (2003) Novel 2-phenyl-2,5-dihydropyrazolo[4,3-c]quinolin-3-(3H)-ones (PQs) endowed with high affinity for central benzodiazepine receptor (BzR) were synthesized. In particular, 9-fluoro-2-(2-fluorophenyl)-2,5-dihydro-3H-pyrazolo[4,3-c]quinolin-3-one (2(2)) showed bi... |

Alterations in GABA(A) receptor expression in neonatal ventral hippocampal lesioned rats: comparison of prepubertal and postpubertal periods.
Synapse 61(6) , 357-66, (2007) Rats with neonatal ventral hippocampal lesions (NVHL) have been studied as a neurodevelopmental animal model of schizophrenia. NVHL rats exhibit postpubertal emergence of hyperresponsiveness to stress, suggesting increased mesolimbic dopamine (DA) activity. H... |
