methyl vinyl ketone/melanoma

Cigarette smoke contains many harmful chemicals, which contribute to the pathogenesis of smoking-related diseases such as chronic obstructive pulmonary disease, cancer and cardiovascular disease. The cytotoxicity of cigarette smoke is well documented, but the definitive mechanism behind its toxicity

The major toxicants in cigarette smoke, α,β-unsaturated aldehydes, such as acrolein (ACR) and crotonaldehyde (CA), and α,β-unsaturated ketone, methyl vinyl ketone (MVK), are known to form Michael-type adducts with glutathione (GSH) and consequently cause intracellular GSH depletion, which is

Highly reactive α,β-unsaturated carbonyl compounds, such as acrolein (ACR), crotonaldehyde (CA) and methyl vinyl ketone (MVK), are environmental pollutants present in high concentrations in cigarette smoke. We have previously found that these carbonyl compounds in cigarette smoke extract (CSE) react

Cigarette smoke contains many harmful chemicals that contribute to the pathogenesis of smoking-related diseases such as chronic obstructive pulmonary disease, cancer, and cardiovascular disease. Many studies have been done to identify cytotoxic chemicals in cigarette smoke and elucidate the onset of

α,β-Unsaturated carbonyl compounds readily form adducts with SH or NH₂ residues, which are nucleophilic agents, by Michael addition. Glutathione (GSH) is a tripeptide that contains an SH residue and functions as an antioxidant. We demonstrated previously that acrolein (ACR),
