Description

6-ethylguanine is an alkylated guanine base that can arise from exposure to alkylating agents, such as those found in tobacco smoke and certain industrial chemicals. It is a mutagenic compound, meaning it can induce changes in DNA sequence. This occurs because 6-ethylguanine can mispair with thymine during DNA replication, leading to a G to A transition mutation. Studies of 6-ethylguanine focus on understanding its role in mutagenesis, carcinogenesis, and the development of various diseases. Research investigates its mechanisms of formation, its interactions with DNA repair pathways, and its potential as a biomarker for exposure to alkylating agents. Furthermore, researchers are exploring the use of 6-ethylguanine as a tool to study DNA damage and repair processes.'
