Two distinct benzodiazepine receptors are solubilized differentially by various detergents. The receptor sites that resist solubilization, designated type I, are most highly concentrated in the cerebellum and corpus striatum whereas the more readily solubilized receptors, type II, are most enriched in the hippocampus. The type I receptors display higher affinity for beta-carboline esters and a ...
a series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. the 4-amino-1,2,4-triazole-5-thione analogues (ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...

The ability of several homologous benzodiazepine and heterologous nonbenzodiazepine ligands to alter the conductance increase induced in spinal cord neurons by gamma-aminobutyric acid (GABA) was determined. Complete dose-response curves were carried out on individual neurons, reducing error introduced by cell-to-cell variability. The efficacies of modulation differ for "classical" benzodiazepin...

The GABA(A) receptor alpha2/alpha3 subtype-selective compound 7-(1,1-dimethylethyl)-6-(2-ethyl-2H-1,2,4-triazol-3-ylmethoxy)-3-(2-fluorophenyl)-1,2,4-triazolo[4,3-b]pyridazine (TPA023; also known as MK-0777) is a triazolopyridazine that has similar, subnanomolar affinity for the benzodiazepine binding site of alpha1-, alpha2-, alpha3-, and alpha5-containing GABA(A) receptors and has partial ago...
Activation of the MET/HGF pathway is common in human cancer and is thought to promote tumor initiation, metastasis, angiogenesis, and resistance to diverse therapies. We report here the pharmacologic characterization of the triazolopyridazine derivative SAR125844, a potent and highly selective inhibitor of the MET receptor tyrosine kinase (RTK), for intravenous administration. SAR125844 display...
