Descrizione generale

6-O-Methylguanine is a purine derivative and its binding affinity has been examined by B. subtilis xpt-pbuX guanine riboswitch (GR) using isothermal titration calorimetry (ITC). 6-O-Methylguanine is formed during the alkylation of a number of purified tRNA preparations, via reaction with the carcinogens, N-methyl-N-nitrosourea .

Cultured human cells are invaluable biological models for mechanistic studies of genotoxic chemicals and drugs. Continuing replacement of animals in toxicity testing will further increase the importance of in vitro cell systems, which should accurately reproduce key in vivo characteristics

Since methylation at the N-7 and O(6) positions of guanine and the N-3 position of adenine in DNA are the predominant reaction sites, N(7)-methylguanine (N(7)-MeG), O(6)-methylguanine (O(6)-MeG), and N(3)-methyladenine (N(3)-MeA) have been suggested as good biomarkers for assessing exposure to
