ToxPrint is a public set of chemotypes developed by Altamira LLC for FDA CFSAN’s CERES project. ToxPrint contains three basic subsets: generic structural fragments, Ashby-Tennant genotoxic carcinogen rules (Ashby, J.; Tennant, R.W., 1988), cancer TTC categories (Kroes, R. et. al. 2004).

ToxPrint is implemented in CSRML language and can be applied using the publicly available ChemoTyper application.

ToxPrint chemotypes can be downloaded free-of-charge for public use.
