Those issues come up with particular frequency in cases involving enantiomers
and other efforts to modify a known chemical compound in well-understood ways.
1981) Chromatographic resolution of enantiomers
having aromatic group by optically active poly(triphenylmethyl methacrylate).
When polymer is exposed to a racemate solution the polymer adsorbs one of the enantiomer
with notable selectivity [7 8].
The two linalool enantiomers
were identified by both retention time and corresponding mass spectra (results not shown).
Baseline resolution of the 6 enantiomers
from an [alpha]-, [beta]-, and [gamma]-HBCD mixture was achieved on [beta]-permethylated cyclodextrin bonded (NUCLEODEX, Macherey-Nagel, GmbH, Diiren, Germany) chiral LC column (4 x 200 mm, 5[micro]m) .
Pharmacokinetics and pharmacodynamics of ketoprofen enantiomers
in the horse.
The effect of bilobalide on the decrease in plasma concentration of warfarin enantiomers
was clearer for the (R)-isomer than for the (S)-isomer.
The natural enantiomer
of the RNA precursor molecules formed a crystal structure visible to the naked eye.
In addition, the (+) - enantiomer
inhibits sero-tonin uptake and the (-) - enantiomer
is a potent no-radrenaline inhibitor, complementary properties which result in a synergistic antinciceptive interac-tion between the two enantiomers
The two enantiomers
often display different characteristics, so there is considerable financial benefit to separating them cheaply.
The animal data for vigabatrin (Sabril; C), an equal mixture of active and inactive enantiomers
, suggest risk, as do the human data.
A representative chromatogram showing resolution of derivatives of enantiomers
is shown in Fig-2.
