Antimutagen

Last updated

Antimutagens are the agents that interfere with the mutagenicity of a substance. [1] The interference can be in the form of prevention of the transformation of a promutagenic compound into actual active mutagen, inactivation, or otherwise the prevention of Mutagen-DNA reaction. [2]

Contents

Antimutagens can be classified into: Desmutagens, that inactivate the chemical interactions before the mutagen attacks the genes and Bio-antimutagens, that stop the mutation process once after the genes are damaged by mutagens. [2] There are a number of naturally occurring anti-mutagens that show their efficient action. [3] [4] [5]

Examples of antimutagens

Micronutrients

Nutrients such as vitamins and minerals are examples of micronutrients that are necessary for the proper maintenance of metabolism homeostasis in humans and other species. Micronutrients are also pointed to perform a role in genome stability acting as potential antimutagenic agents [6] (see the examples below):

UV blockers

Sunscreens are products commonly known by their capacity of protecting skin against sunburns. The active components present in sunscreens can vary, thus affecting the mechanism of protection against UV light, which can be done through absorption or reflection of UV energy. [8] As UV light can cause mutations by DNA damaging, sunscreen is considered an antimutagenic compound as it blocks the action of the UV light to induce mutagenesis in cells, basically the sunscreen inhibit the penetration of the mutagen. [9]

Tumor suppressor genes

These genes have the function of protecting cells against tumor-like behaviour, such as higher proliferative rates and unlimited growth. It is common to find those genes down regulated or even inactivated in tumor cells. Thus, tumor suppressor genes can be recognized as antimutagenic agents. [10]
