    Patent Baristas

  • Believing that there was no advantage to separation of the enantiomers of thienopyridines, and no other racemates were separated until November 1985 when Sanofi then determined the biological properties of the enantiomers of PCR 4099, and found that they had the rare characteristic of "absolute stereoselectivity": the dextrorotatory enantiomer provided all of the favorable antiplatelet activity but with no significant neurotoxicity, while the levorotatory enantiomer produced no antiplatelet activity but virtually all of the neurotoxicity.

    Patent Baristas

  • 42, S225-S227, (1991) • Both enantiomers of quinacrine and the racemic form of the drug showed equal activity in vitro against chloroquine-sensitive and - resistant strains of Plasmodium falciparum, without detectable stereoselectivity.
