Several scientific studies have shown that 6-MITC possesses interesting antimicrobial, anti-inflammatory, antiplatelet and antioxidant properties which therefore suggested us it could have an interesting chemopreventive potential. In a recent publication, we demonstrated, in two different leukemia cell lines, its ability to modulate several mechanisms supporting its antitumor activity. For this reason, we thought useful to continue the research, by investigating the potential antimutagenic activity of 6-MITC and thus better define its profile as a possible chemopreventive agent.

Current Trends and Future Perspectives of Antimutagenic Agents

In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA , of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer , mutagens are therefore also likely to be carcinogens , although not always necessarily so. All mutagens have characteristic mutational signatures with some chemicals becoming mutagenic through cellular processes. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis , errors in DNA replication , repair and recombination. The first mutagens to be identified were carcinogens , substances that were shown to be linked to cancer.

Mutation is the process leading to heritable changes in DNA caused mainly by internal and external factors. Recently, studies on mutagenic agents have been increased due to increasing in mutation-related disease. The antimutagenic effect is desired to prevent mutation on genes or to inactivate the mutagenic agent. It seems that the interest in antimutagenic substances displaying multiple mechanisms of action will be an important trend in the research and development of new antimutagenic compounds in the near future. Therefore, this chapter displays various possible mechanisms of action for antimutagenic agent and introduces different types of antimutagens, natural and synthetic, that are considered very important. Genotoxicity and Mutagenicity - Mechanisms and Test Methods. Mutagenicity is the process of induction of permanent heritable changes in the DNA sequence of living systems [ 1 ].

Mutagenicity refers to the induction of permanent changes in the DNA sequence of an organism, which may result in a heritable change in the characteristics of living systems. Antimutagenic agents are able to counteract the effects of mutagens. This group of agents includes both natural and synthetic compounds. Based on their mechanism of action among antimutagens, several classes of compounds may be distinguished. These are compounds with antioxidant activity; compounds that inhibit the activation of mutagens; blocking agents; as well as compounds characterized with several modes of action.

 Милый, я… я сейчас задохнусь! - Ей стало дурно. Все ее внутренности сдавило этой немыслимой тяжестью.  - Despiertate! - Ее пальцы инстинктивно вцепились ему в волосы.

Но. Увы, она уже знала ответ. Так вот какова месть Танкадо. Уничтожение ТРАНСТЕКСТА. Уже несколько лет Танкадо пытался рассказать миру о ТРАНСТЕКСТЕ, но ему никто не хотел верить.

Это была сумка Меган.


Беккер вильнул в сторону, и тут же боковое зеркало превратилось в осколки. Он почувствовал, как этот удар передался на руль, и плотнее прижался к мотоциклу. Боже всевышний. Похоже, мне не уйти. Асфальт впереди становился светлее и ярче.

Треск лесного пожара, вой торнадо, шипение горячего гейзера… все они слились в гуле дрожащего корпуса машины. Это было дыхание дьявола, ищущее выхода и вырывающееся из закрытой пещеры. Стратмор так и остался стоять на коленях, парализованный ужасающим, неуклонно приближающимся звуком. Самый дорогой компьютер в мире на его глазах превращался в восьмиэтажный ад. Стратмор медленно повернулся к Сьюзан.

 - Он повернулся к Сьюзан.  - Я понял, что Цифровую крепость не следует останавливать. Сьюзан смотрела на него в растерянности.
