Принципиально новый препарат для лечения гонореи будет содержать монооксид углерода
Принципиально новый препарат для лечения гонореи будет содержать монооксид углерода
Гонорея — одно из наиболее распространенных заболеваний, передающихся половым путем. В последние годы регистрируются случаи заражения высокорезистентным к антибиотикам штаммом Neisseria gonorrhoeae. Команда ученых биологического и химического факультетов Йоркского университета (University of York»s Departments of Biology and Chemistry) обратила внимание на способность молекул, высвобождающих монооксид углерода (СО), усиливать действие антибиотиков, что открывает огромные возможности для лечения бактериальных инфекций, в том числе гонококковой, поскольку гонококк обладает значительной чувствительностью к токсическим свойствам СО. Работа опубликована в журнале Medicinal Chemistry Communications в декабре 2016 года
Профессор Ян Фэрлемб (Ian Fairlamb), принимавший участие в исследовании, отмечает, что у гонококка необходимо ингибировать при помощи СО только один-единственный фермент, чтобы бактерия погибла, поэтому при воздействии на бактериальные клетки достаточно низких концентраций донаторов СО.
На культуре клеток исследователями было убедительно показано, что в присутствии донаторов СО значительно сокращалось количество жизнеспособных колоний гонококков. Следующий этап работы — разработка двух лекарственных форм: таблетки или крем, это позволит использовать результаты фундаментальных исследований в клинических испытаниях. Ученые считают свою работу прорывом, поскольку она может привести к созданию принципиально новых способов лечения бактериальных инфекций.
