Diastereomers of N(12)-(2-hydroxy-2-phenylethyl)cytisine were synthesized by reduction of N(12)-(2-oxo-2-phenylethyl)cytisine by Yamamoto reagent. Their structures were solved using x-ray structure analysis.

Derivatives of N-(2-hydroxyethyl)cytisine, N-(2-hydroxypropyl)-, N-(2-hydroxy-2-(1-adamantyl)ethyl)-, and N-(2-hydroxy-2-phenylethyl)cytisine, were synthesized by reduction of N-(2-oxopropyl)-, N-(2-oxo-2-(1-adamantyl)ethyl)-and N-(2-oxo-2-phenylethyl)cytisine with metal hydrides. The antiarrhythmic and analgesic activities of the prepared compounds were investigated.
respectively. While the affinity for α7 subtype was rather poor (Ki from 0.4 to >50 μM), the affinity for α4β2 subtype was very interesting, with nanomolar Ki values for the best compounds. The N-substituted cytisines were docked into the rat and human α4β2 nAChR models based on the extracellular domain of a molluscan acetylcholinebinding protein. The docking results agreed with the binding data, allowing
