additional information
-
no inhibitor: taurodeoxycholate
-
4-nitrobenzoate
-
inhibition of COQ2 by 4-nitrobenzoate, leading to 40-50% residual CoQ10, is associated with increased oxidative stress and reduced viability, together with moderately decreased ATP levels and ATP/ADP ratio
4-nitrobenzoate
-
competitive enzyme inhibition, cell treatement with 4-nitrobenzoate leads to a decrease in coenzyme Q content, but 4-nitrobenzoate treatment has no apparent toxic effect on the cells and does not decrease Q concentration by inducing oxidative stress
