Discovery of a Novel Muscarinic Receptor PET Radioligand with Rapid Kinetics in the Monkey Brain

Positron emission tomography (PET), together with a suitable radioligand, is one of the more prominent methods for measuring changes in synaptic neurotransmitter concentrations in vivo. The radioligand of choice for such measurements on the cholinergic sy

AMIDINE-CONTAINING COMPOUNDS USEFUL AS MUSCARINIC RECEPTOR ANTAGONISTS

The invention relates to compounds of formula I: or a pharmaceutically acceptable salt thereof, where R1-3, R5, R7, a, b, Q, X, X′, X″, Y, Z, and Ar are as defined in the specification. These compounds are muscarinic recep

Stereoselective synthesis of the optical isomers of a new muscarinic receptor antagonist, quinuclidin-3-yl 2-(cyclopent-1-enyl)-2-hydroxy-2- phenylacetate

The enantiopure isomers of a new muscarinic receptor antagonist, quinuclidin-3-yl 2-(cyclopent-1-enyl)-2-hydroxy-2-phenylacetate were synthesised by a practical stereoselective synthetic method, using pivaldehyde as steric hindrance agent from the chiral starting material, (S) or (R)-mandelic acid. The isomers were obtained with 72-78% yields in 98-99% e.e.
