DNA双螺旋内部的杂环碱基序列构成了驱动所有生物体运作的遗传密码。因此,细胞DNA的化学修饰可以产生深远的生物学后果也就不足为奇了。因此,DNA损伤的有机化学对包括药物化学、毒理学和生物技术在内的各个领域都具有根本的重要性。这篇综述的目的是提供一个简单的概述,在生理条件下,导致DNA损伤的常见类型的化学反应。
The sequence of heterocyclic bases on the interior of the DNA double helix constitutes the genetic code that drives the operation of all living organisms. With this said, it is not surprising that chemical modification of cellular DNA can have profound biological consequences. Therefore, the organic chemistry of DNA damage is fundamentally important to diverse fields including medicinal chemistry, toxicology, and biotechnology. This review is designed to provide a brief overview of the common types of chemical reactions that lead to DNA damage under physiological conditions.
