Synthesis, σ1, σ2-receptors binding affinity and antiproliferative action of new C1-substituted adamantanes
摘要:
The synthesis of N-{4-[a-(1-adamantyl)benzyl]phenyl}piperazines 2a-e is described. The in vitro antiproliferative activity of most compounds against main cancer cell lines is significant. The sigma(1),sigma(2)-receptors and sodium channels binding affinity of compounds 2 were investigated. One of the most active analogs, 2a, had an interesting in vivo anticancer profile against the BxPC-3 and Mia-Paca-2 pancreas cancer cell lines with caspase-3 activation, which was associated with an anagelsic activity against the neuropathic pain.

This invention relates to the use sigma-2 receptor antagonists, and of pharmaceutical compositions comprising such compounds, in methods for inhibiting Abeta-associated synapse loss or synaptic dysfunction in neuronal cells, modulating an Abeta-associated membrane trafficking change in neuronal cells, and treating cognitive decline associated with Abeta pathology and more broadly treating with such compounds and compositions neurodegenerative diseases and disorders associated with Abeta pathology. This invention also relates to methods for screening compounds for activity in inhibiting cognitive decline on the basis of their ability to bind to a sigma-2 receptor.
