The intrinsic conformational and structural properties of the tropinone azabicycle have been investigated in a supersonic jet expansion using rotational spectroscopy. The spectrum revealed the presence of equatorial and axial conformers originated by the inversion of the N-methyl group, with

The synthesis of O-propynyloximes of N-methylpiperidinone, 3-tropinone, and 3-quinuclidinone, containing several pyrazole frameworks is described, together with their muscarinic receptor affinities. Compounds derived from N-methylpiperidinone or 3-tropinone and N-(4-methoxybenzyl)- or N-(2,4,6-trimethylbenzoyl)pyrazole showed moderate activity for muscarinic receptors in the rat

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.
