Специфические ингибиторы ферментов этого пути составят новый класс антибиотиков против возбудителей ряда опасный заболеваний (малярии, туберкулеза, сибирской язвы и др.) и, в связи с его отсутствием у человека и животных, будут сочетать высокую эффективность действия с низкой токсичностью. Синтезирован ряд производных 2-С-метил-D-эритрит-2,4- циклодифосфата (МЭЦ) и проверено их ингибирующее действие в модельной системе (включение14С-МЭЦ в изопреноиды хромопластов перца). 4-Фосфо-метилэритрит-1,2- циклофосфат, бензиловый эфир и бензили-деновый диэфир МЭЦ ингибировали этот процесс с 1С50 порядка 1,7-5 мМ. Небольшое (около 10%) подавление включения радиоактивного субстрата наблюдали также в случае изопропилиденового и диметилового эфиров МЭЦ.</p></abstract><trans-abstract xml:lang="en"><p>The recently discovered nonmevalonate pathway of isoprenoid biosynthesis Is a prospective target in screening of new antibiotics. Because of the absence of the pathway in the animal cells, the specific inhibitors of the pathway will be a new class of antibiotics against many pathogens (which cause e.g. malaria, tuberculosis, etc), combining high efficiency and low toxicity. Several derivatives of 2-C-methyl-D-erythritol-2,4-cyclodiphosphate (MEC) were synthesized. 4-Phospho-methyl-D-erythritol-1,2-cyclophosphate, benzyl ether and benzyliden derivative of MEC inhibited the14C-MEC incorporation into isoprenoids of chromoplasts from red pepper with IC50 of 1.7-5 мМ. Some inhibition (about 10 %) was also observed with the use of dimethyl ether and isopropyliden derivative of MEC.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поиск антибиотиков</kwd><kwd>ингибиторы биосинтеза изопреноидов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibiotics screening</kwd><kwd>isoprenoid biosynthesis inhibitors</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">Rohmer М., Khani М., Simonin P. et al.
