preparation example
[0126] All reactions involving air-sensitive reagents or intermediates were performed under nitrogen and anhydrous solvents. Magnesium sulfate was used as a drying agent during the operation, and the solvent was evaporated under reduced pressure.
[0127] 1,4-Diazabicyclo[3.2.2]nonane (intermediate compound)
[0128] according to J. Med. Chem. 1993362311-2320 (and according to a slightly modified procedure described below) to prepare the title compound.
[0129] 1,4-Diazabicyclo[3.2.2]nonane (intermediate compound)
[0130] To a solution of 1,4-diazabicyclo[3.2.2]nonan-3-one (15.8 g; 113 mmol) in dry dioxane (130 ml) was added LiAlH4 (4.9 g; 130mmol). The mixture was refluxed for 6 hours and then allowed to reach room temperature. Water (5 ml in 10 ml of dioxane) was added dropwise to the reaction mixture, the mixture was stirred for 0.5 hours and then filtered off through a glass filter. The solvent was evaporated and the residue was distilled with a Kugelrohr appa...

[0148] in the hippocampus 3 Inhibition of H-α-bungarotoxin binding in vitro
[0149] In this example, it was determined that compounds of the invention bind to the nicotinic receptor alpha 7 - Subtype affinity.
[0150] α-bungarotoxin is a peptide isolated from the venom of the cobra snake (Bungarus multicinctus). It has a high affinity for the nicotinic receptors of nerves and neuromuscular where it is a potent antagonist.
[0151] 3 H-α-bungarotoxin is labeled by α in the brain 7 Subtype isoforms and alpha in the neuromuscular junction 1 Isoforms of nicotinic acetylcholine receptors.
[0152] tissue preparation
[0153]At predetermined time points after injection, mice were sacrificed by decapitation, hippocampi were rapidly excised on ice, and the tissue from each animal was weighed. Preparations were carried out at 0-4°C unless otherwise stated. Using an Ultra-Turrax homogenizer, homogenize individual hippocampi (2 per animal) for 10 seconds in 75 volumes of ice...
