Over the last couple of weeks, we have received news that four papers, submitted earlier this year to the Journal of Computational Toxicology, have been accepted for publication.
- Developing Structure-Activity Relationships for N-Nitrosamine Activity1
This paper outlines N-Nitrosamine carcinogenic potency ranges and describes specific structural features that have clear effects on these ranges. It highlights how N-nitrosamine structure-activity relationships require the investigation of metabolism, DNA binding and DNA repair. Such analysis, based on the presence or absence of structural features, can support read-across for novel N-nitrosamines.
2. In silico approaches in organ toxicity hazard assessment: current status and future needs in predicting liver toxicity2
This paper summarizes the biological mechanisms and processes underlying liver toxicity and describes specific experimental approaches to support the prediction of hepatotoxicity. It discusses the role of in silico approaches and highlights challenges to the adoption of these methods. A proposed framework for the integration of in silico and experimental information is presented.
3. In silico approaches in organ toxicity hazard assessment: current status and future needs for predicting heart, kidney and lung toxicities3
An overview of the key characteristics/mechanisms of heart, lung and kidney toxicity is presented, along with an assessment of how computational methods can be used to understand chemicals that could induce organ toxicity. Obstacles to the development of computational methods predictive of target organ toxicity are discussed.
4. In silico approaches in carcinogenicity hazard assessment: current status and future needs4
The paper summarizes the 10 key characteristics (KCs) of carcinogens and assesses how current in silico methods address each of these KCs. The paper indicates where experimental methods need to be implemented and databases generated. The paper also highlights interactions among the KCs with the different stages of carcinogenesis.
Three of these publications2-4 will appear in a special issue of the journal on the in silico toxicology protocol initiative.
We would like to thank all co-authors for their contribution to these manuscripts.
