STEREOCHEMISTRY IN ANAESTHESIA

Clinical and Experimental Pharmacology and Physiology, 1997
SUMMARY1. Interest in the pharmacokinetic and pharmacodynamic properties of the enantiomers of chiral drugs has greatly increased in recent years. This is particularly so for agents used in anaesthesia.2. Chiral compounds are those that can exist in two non‐superimposable forms. Each form is termed an enantiomer or stereoisomer.

The stereochemistry of pinidine

Tetrahedron, 1965
Abstract The stereochemistry of pinidine, a piperidine alkaloid from Pinus sabiniana, was established by chemical and spectroscopic methods as 2-(R)-methyl-6-(R)-(2-trans-propenyl)-piperidine (XXI). Some interesting rearrangements which occurred during degradative studies are discussed, and the configuration of pinidine is compared with that of ...

Stereochemistry and Bioequivalence

The Journal of Clinical Pharmacology, 1992
Despite the fact that many important drugs are chiral, for a variety of reasons they are marketed as racemates (i.e., an equal proportion of two enantiomers). Although enantiomers of racemic drugs often differ from one another in their pharmacodynamic and pharmacokinetic properties, bioequivalence assessments are made using nonstereospecific assays ...
