Glutathione (GSH) conjugates with dopamine (DA)-derived quinones to form reactive or non-reactive GSH-conjugates [PDF]

, 2009
In this study we demonstrate for the first time that GSH could rapidly conjugate with dopamine (DA)-derived DA-o-quinones without enzymatic catalysis to form short-lived intermediate GSH-conjugates (2-S-GSH-DA-o-quinone and 5-S-GSH-DA-o-quinone).
