Synthesis, Structure, and Biological Activity of Cinnamoyl-Containing Cytisine and Anabasine Alkaloids Derivatives

The reactions of the cytisine and anabasine alkaloids with cinnamic acid chloride have been studied, and hydrazinolysis of the resulting N-cinnamoylcytisine and N-cinnamoylanabazine has been carried out. The reaction of cinnamoyl isothiocyanate with alkaloids has afforded the corresponding thiourea derivatives. Antimicrobial and cytotoxic activity of cinnamoyl-containing derivatives of these alkaloids has been evaluated.
