(6S ,12AS)-Tadalafil is an inactive enantiomer of "Tadalafil" which is the active ingredient in Cialis which is used to treat erectile dysfunction. Tadalafil has 4 isomers [(RR), (SS), (RS), and (SR)], of which (RR) is the name-sake isomer and potent inhibitor of phosphodiesterase-5. The (RS) diastereomer is the only other isomer with some PDE-5 inhibitory activity.
