The present invention relates to substituted cytisine compounds that are useful in treating diseases impacted by a nicotinic ACh receptor. One aspect of the invention relates to 10-substituted cytisine compounds. In certain instances, the cytisine is substituted in the 10-position by an alkyl, aryl or aralkyl group. The present invention also relates to a pharmaceutical composition comprises the substituted cytisine compound or the 10-substituted cytisine compound. The invention also relates to a method of modulation a nicotinic ACh receptor in a mammal, comprising the step of administering to a mammal in need thereof a therapeutically effective amount of a substituted cytisine. In certain instances, the substituted cytisine is a 10-substituted cytisine. Another aspect of the present invention relates a method of treating a disease impacted by a nicotinic ACh receptor, comprising the step of administering to a mammal in need thereof a therapeutically effective amount of a substituted cytisine. In certain instances, the substituted cytisine is a 10-substituted cytisine.

We report the synthesis and pharmacological properties of several cytisine derivatives. Among them, two 10-substitutedderivatives showed much higher selectivities for the alpha4beta2 nAChR subtype in binding assays than cytisine. The 9-vinyl derivative was found to have a very similar agonist activity profile to that of cytisine.
