S3QEL-2 is a selective complex III superoxide-producing site inhibitor with neuroprotective effects that inhibits PC-3 cell proliferation in pyruvate-starved medium in a dose-dependent manner.

D-proline is an isomer of the naturally occurring amino acid L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin but there is also evidence that they are endogenously produced through amino acid racemase activity.

Tenivastatin (Simvastatin acid) is an anti-hyperlipidemic HMG-CoA reductase inhibitor that inhibits the production of reactive oxygen species (ROS) and can be used in the study of primary hyperlipidemia.
