NFLX is reported to be slightly more active than the parent
compound (Stokes and Holtz, 1997). Enantiomers of FLX have a
similar potency as inhibitors of the serotonin reuptake pump
whereas enantiomers of NFLX act differently, with (S)-NFLX being
the more potent enantiomer regarding its inhibition capacity
(Fuller et al., 1992)
