Structural alerts for estimating the carcinogenicity of pesticides and biocides

SAR and QSAR in Environmental Research, 2011
More than 20 years ago, Ashby and Tennant showed the interest of structural alerts for the prediction of the carcinogenicity of chemicals. These structural alerts are functional groups or structural features of various sizes that are linked to the level of carcinogenicity of chemicals.

Mutagenic potential and structural alerts of phytotoxins

Food and Chemical Toxicology, 2023
Toxic plant-produced chemicals, so-called phytotoxins, constitute a category of natural compounds belonging to a diversity of chemical classes. Some of them (e.g., alkaloids, terpenes, saponins) are associated with high toxic potency, while for many of others no toxicological data is available. In this study, the mutagenic potential of 1586 phytotoxins,

From Structural Alerts to Signature Fragment Alerts: A Case Study on Pyrrolizidine Alkaloids

Chemical Research in Toxicology, 2023
Even though modeling is considered a valid alternative to mutagenicity testing for substances with known structures, it can be applied for mixtures only if all of the single chemical structures are identified. Within the present work, we investigate a new avenue to exploit computational toxicology for mixtures, such as plant-based food ingredients ...
