Ricinine is an alkaloid of Ricinus communis displaying numerous biological properties. Ricinidine (1-Methyl-2-oxo-1,2-dihydro-3-pyridinecarbonitrile) and new N-analogues of Ricinidine were obtained by the reaction of ethyl α-ethoxyethylidenecyanoacetate with various amines. Earlier, the ethyl α-ethoxyethylidenecyanoacetate was easily prepared from ethyl cyanoacetate. Biologically amines as tryptamine and histamine were used in order to introduce a second pharmacophore on the target molecule. ecsoc-25-11676
