41) It is also sometimes the case that while, say, the negative enantiomer is responsible for the therapeutic benefits of the drug, the positive enantiomer is actually inhibiting those benefits, so removing the positive enantiomer from the racemic mixture will have a more than two-fold increase in the therapeutic effects of the drug.
Warfarin is a racemic mixture and it is metabolized via cytochrome enzymes in the liver.
It could be much easier and cheaper to prepare the racemic mixture by classical simple nonenantioselective chemical synthesis and this mixture would be separated in a following step by enantioselective physical methods.
TNX-201 is also likely to possess favourable safety and tolerability relative to both the other isomer and to the racemic mixture, and potentially have an improved clinical profile as compared to the unapproved racemic IMH for headache indications.

The sulfanylation of racemic mixture of 2-methylsulfinyl-1-indanone in these conditions was monitored by TLC and after 3 hours the reaction finished.
This allows selective chemistry, for example, regio-selectively transforming a single functionality (out of several) in a single molecule or, more importantly, effecting the biotransformation of one isomer in a racemic mixture, facilitating its separation into the component isomers.
