In tropane-alkaloid producing plants and root cultures, the reduction of tropinone is a branch-point in secondary metabolism. Two different reductases stereospecifically form the isomeric alcohols tropine (tropan-3 alpha-ol) and pseudotropine (tropan-3 beta-ol). We describe here the purification and characterization of

Tropane alkaloids typically occur in the Solanaceae and are also found in Cochlearia officinalis, a member of the Brassicaceae. Tropinone reductases are key enzymes of tropane alkaloid metabolism. Two different tropinone reductases form one stereoisomeric product each, either tropine for

A number of O-alkynyloximes of tropinone and N-methyl-4-piperidinone have been synthesized and evaluated for muscarinic activity. The affinities of these oximes were tested in homogenates of cerebral cortex, heart, and submandibulary glands from rats using [3H]pirenzepine and [3H]-N-methylscopolamine as radioligands.
