Executive Summary
Compound | Troglitazone |
Toxicities | Cholestasis, cell death, and fibrosis |
Mechanisms | Direct inhibition of mitochondrial and other oxidative functions by the compound itself. Metabolized via multiple pathways to generate active metabolites, including quinones and inhibitors of hepatic anion transporters. |
Comments | Although troglitazone has been one of the major inducers of hepatotoxicity in clinical use, the toxicity is idiosyncratic. Any and all of several mechanisms may be manifested in different patient populations, and there is no consensus of a single primary cause of toxicity either in the clinic or in in vitro experiments. In addition, the biology of the PPARγ target is not fully understood and may contribute to ‘omics expression patterns in an uninterpretable manner. For these reasons, we recommend that any in vitro profile observed in SEURAT assays will not be interpretable in a predictive sense. |
Recommended as Standard | No |

- ↑ Toxicity should be observed clinically with higher frequency at higher doses. If toxicity is idiosyncratic due to defects in metabolism that result in higher than normal exposure, then this toxicity is still considered to fit our definition of dose-dependent toxicity. If toxicity is idiosyncratic due to an increased sensitivity of the organ to the toxin - due to disease, genetics, or co-administered drug, for example - then this toxicity is outside our area of interest.
- ↑ The in vivo therapeutic window is used to estimate an appropriate concentration for in vitro toxicity assays. This in vitro concentration should also be consistent with the exposure implied by pharmacokinetics parameters.
- ↑ 25.0 25.1 We prefer compounds that require metabolic activation, although standards that are active in themselves will be accepted if they have otherwise valuable properties. We require knowing the active metabolite, and we prefer compounds where the metabolite is stable and can be independently tested in order to verify the mechanism of toxicity as well as of metabolic activation in the test cell line.
- ↑ Literature data for at least one, but not necessarily all, of the ‘omics datasets is desired. This requirement can be waived in special cases.
- ↑ 27.0 27.1 27.2 27.3 27.4 The IC50’s for in vitro efficacy and toxicity should be consistent with the therapeutic ratio observed in the clinic. These parameters will be dependent on specific cell type and culture conditions, but differences of more than 30-fold in the in vitro vs. in vivo therapeutic ratios should be considered suspect and carefully justified.
- ↑ This is not a equirement, but compounds utilized in the EPA testing program can be assumed to have physical properties verified to be suitable for in vitro cellular assays.
- ↑ Sparing soluble compounds may be assayed for solubility in serum and the percent serum used specified here.
- ↑ This property will be measured when a sample of compound becomes available.
