Структурные и электронные свойства мелатонина, триптофана и окисленных производных данных молекул были исследованы теоретически с использованием АМ1 полуэмпирического метода и ab initio метода. Высокая радикал-скэвенджерная способность мелатонина может быть обусловлена высокими значениями площади поверхности и дипольного момента молекулы, который отражает плотность заряда молекулы. С термодинамической точки зрения N1-ацетил- N2 -формил-5-метоксикинурамин (AФMK) является самым стабильным продуктом окисления мелатонина. Сравнительное исследование радикал-скэвенджерных, структурных и электронных свойства молекул мелатонина, его предшественника - триптофана продемонстрировало, что мелатонин в отличие от триптофана является потенциальным липидным антиоксидантом и эффективным скэвенджером алкоксильных и пероксильных радикалов.</p></abstract><trans-abstract xml:lang="en"><p>Structural and electronic properties of melatonin, tryptophan, and oxidative products of these molecules were determined theoretically by performing semi-empirical and ab initio calculations. The radical scavenging effects of melatonin and tryptophan were studied using the alkoxyl and peroxyl radical- generating systems. We have shown that melatonin, rather than tryptophan, is a potent lipid antioxidant and an effective scavenger of alkoxyl- and peroxyl radicals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>структура</kwd><kwd>электронные свойства</kwd><kwd>радикал-скэвенжер</kwd><kwd>мелатонин</kwd><kwd>триптофан</kwd><kwd>structure</kwd><kwd>electronic properties</kwd><kwd>radical-scavenger</kwd><kwd>melatonin</kwd><kwd>tryptophan</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pharmacological actions of melatonin in oxygen radical pathophysiology / R.
