“…As early as 1964, HAs were first recognized as a potential mutagenic/carcinogenic compound, which can covalently bind with DNA to form adducts and mutate normal cells into tumor cells(Gibis, 2016). To date, more than 30 HAs had been isolated and identified at ng/g levels in cooked foods, and the common HAs can be found in cooked foods are 2‐amino‐3‐methyl‐imidazo [4,5‐f]quinoline (IQ), 2‐amino‐3‐methylimidazo [4,5‐f]quinoxaline (IQx), 2‐amino3,4‐dimethylimidazo [4,5‐f]quinoline (MeIQ), 2‐amino‐3,8dimethylimidazo [4,5‐f] quinoxaline (MeIQx), 2‐amino‐1methyl‐6‐phenylimidazo [4,5‐b]pyridine (PhIP), 3‐Amino‐1,4‐dimethyl‐5H‐pyrido[4,3‐b]indole (Trp‐P‐1), 3‐Amino‐1‐methyl‐5H‐pyrido[4,3‐b]indole (Trp‐P‐2), 2‐Amino‐9H‐dipyrido[2,3‐b]indole (AaC), 2‐Amino‐3‐methyl‐9H‐dipyrido[2,3‐b]indole (MeAaC), 9H‐pyrido[3,4‐b]indole (Norharman) and 1‐methyl‐9H‐pyrido[3,4‐b]indole (Harman) (Scheme 1; Savinova & Yerzhanova, 2021; Xue et al, 2022; Khan et al, 2019; Rahman et al, 2014; Yang et al, 2020). In 1993, the International Agency for Research on Cancer (IARC) classified PhIP, MeIQ, AαC, MeAαC and MeIQx as probable (2B) human carcinogens, and IQ as a possible (2A) human carcinogen.…”
