| Description | N-Acetyl-D-cysteine has antioxidant activities and scavenges ROS through the reaction with its thiol group. |
| In vitro | Consistent with the known stereoselectivity of many biological processes, the unnatural D isomer of N-acetylcysteine failed to increase hepatic glutathione. Liver concentrations remained similar to control suggesting that the D isomer was unable to increase the rate of glutathione synthesis. The D isomer further differed from its L enantiomer in failing to increase the plasma concentration and the urinary excretion of inorganic sulfate. Congruent with these observations, much more N-acetyl-D-cysteine (47% of dose) was recovered unchanged in 24 hr urine than N-acetyl-L-cysteine (6.1% of dose)[2]. |
