The tautomerism of the synthesized 3-arylpyrimido[4,5-c]pyridazine-5,7(6H,8H)-diones (1a-d) and 3-aryl-7-thioxo-7,8-dihydro-6H-pyrimido[4,5-c]pyridazine-5-ones (2a-d) was studied in dimethyl sulfoxide (DMSO)-d(6). (1)H NMR spectra of 1a-d showed a clustered water molecule in the structure backbone that is attached by strong intermolecular H bonding. The(More)
1. GABA(B) autoreceptors are a subclass of GABA(B) receptors that inhibit the release of [(3) H]GABA from GABAergic nerve terminals. Baclofen is an agonist that reduces [(3)H]GABA, whilst the antagonist (+)-(S)-5,5-dimethylmorpholinyl-2-acetic acid (Sch 50911) enhances [(3)H]GABA release in electrically-stimulated rat neocortical brain slices preloaded with(More)
