Synthesis and neuropharmacological activity of N-1-adamantylcytisine-12-carbamide and its 12-thiocarbonyl analog

The neuropharmacological activity of two (–)-cytisine derivatives with adamantyl fragments was studied. It was shown that N-1-adamantylcytisine-12-thiocarbamide exhibited in tests in vivo a pronounced mnestic effect, increased the lifespan of laboratory animals under hypoxic conditions, and also enhanced in vitro binding of transcription factors NFAT and NF-κB to the DNA sequences corresponding to them.
