  Synthesis and in vitro evaluation of 4-trichloromethylpyrrolo[1,2-a]quinoxalines as new antiplasmodial agents

  摘要：

  Thanks to a preliminary in vitro screening of several CCl3-substituted-nitrogen containing heterocycles belonging to our chemical library, the 2-trichloromethylquinoxaline scaffold appeared to be of potential interest for developing new antiplasmodial agents. Then, combining these experimental results to the antimalarial properties reported for various pyrrolo[1,2-a]quinoxaline derivatives, an original series of fifteen 7-substituted-4-trichoromethylpyrrolo[1,2-a]quinoxalines was synthesized in a 4 to 5 reaction steps pathway. All molecules were evaluated in vitro toward both their antiplasmodial activity on the K1 multi-resistant Plasmodium falciparum strain and their cytotoxicity on the HepG2 human cell line. Thus, 3 hit molecules were identified, displaying IC50 values in the micromolar range and low cytotoxicity values, reaching good selectivity indexes, in comparison with the reference drugs chloroquine and doxycycline. Structure-activity relationship studies showed that the pyrrolo[1,2-a]quinoxaline scaffold can support selective antiplasmodial activity when substituted at position 4 by a CCl3 group. However, substitution at position 7 of the same scaffold is neither beneficial for cytotoxicity nor favourable for the solubility in the biological media.

  An experimentally simple and convenient synthesis of 4-susbstituted 2-(trichloromethyl)quinazolines by cycloaddition of benzyne with 2-(trichloromethyl)-1,3-diazabutadienes was developed. The 2-(trichloromethyl)-1,3-diazabutadienes (R1 = H and Me) were prepared from trichloroacetamidine and the appropriate N,N-dimethylamide dimethyl acetal or from trichloroacetamidine and a Vilsmeier–Haack reagent

  The invention relates to novel heterocyclic trichloromethyl derivatives, particularly 2-trichloromethyl-substituted quinazoline, benzo (d]-[1,3] -oxazine and benzo[e]-[1,3] -oxazine derivatives, for example 1, 2-dihydro-2 -trichloromethylquinazolin -4-one. The compounds of the invention are at least as effective as prior art trichloromethyl derivatives, which reduce the production of methane during the rumen metabolism of ruminant animals, and increase the formation of propionate at the expense of acetate, and hence improve the animals' rate of growth and their efficiency of food utilisation.

  本发明涉及新型杂环三氯甲基衍生物，特别是2-三氯甲基取代的喹唑啉、苯并(d)-[1,3]-恶嗪和苯并[e]-[1,3]-恶嗪衍生物，例如1，2-二氢-2-三氯甲基喹唑啉-4-酮。本发明的化合物至少与现有技术中的三氯甲基衍生物同样有效，可减少反刍动物瘤胃代谢过程中甲烷的产生，增加丙酸盐的形成，从而提高动物的生长速度和食物利用效率。
