某些电子液体和芳香醛调味剂先前被确定为微粒体重组CYP2A6的抑制剂,CYP2A6是主要的尼古丁代谢酶。然而,由于其反应性,醛类物质可能在到达内质网CYP2A6之前与细胞成分发生反应。为了确定电子液体调味剂是否在细胞系统中抑制CYP2A6,我们利用BEAS-2B细胞过度表达CYP2A6,研究了它们对CYP2A6的影响。我们证明了两种电子液体和三种醛调味剂(肉桂醛、苯甲醛和乙基香兰素)对细胞CYP2A6的抑制呈剂量依赖性。
Certain e-liquids and aromatic aldehyde flavoring agents were previously identified as inhibitors of microsomal recombinant CYP2A6, the primary nicotine-metabolizing enzyme. However, due to their reactive nature, aldehydes may react with cellular components before reaching CYP2A6 in the endoplasmic reticulum. To determine whether e-liquid flavoring agents inhibited CYP2A6 in a cellular system, we investigated their effects on CYP2A6 using BEAS-2B cells transduced to overexpress CYP2A6. We demonstrated that two e-liquids and three aldehyde flavoring agents (cinnamaldehyde, benzaldehyde, and ethyl vanillin) exhibited dose-dependent inhibition of cellular CYP2A6.
