Roles (4)

RoleDescription
mutagenAn agent that increases the frequency of mutations above the normal background level, usually by interacting directly with DNA and causing it damage, including base substitution.
carcinogenic agentA role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
genotoxinA role played by a chemical compound to induce direct or indirect DNA damage. Such damage can potentially lead to the formation of a malignant tumour, but DNA damage does not lead inevitably to the creation of cancerous cells.
Maillard reaction productAny thermal degradation product obtained as a result of a chemical reaction between an amino acid and a reducing sugar (Maillard reaction, a non-enzymatic browning procedure that usually imparts flavour to starch-based food products).

Drug Classes (2)

ClassDescription
