attempt to search for new and alternative antimalarial agents, a series of unsubstituted and 6-trifluoromethyl-1,2,4-triazino[5,6b]indole and 5H-1,2,4-triazolo[1',5',2,3]-1,2,4-triazino[5,6b]indole derivatives were synthesized and their chemical structures confirmed by 1H NMR and 13C NMR, elemental, IR and mass spectrophotometric analyses. The in vitro antimalarial activities of these compounds were evaluated
为了寻找新的和替代的抗疟药,一系列未取代的和6-三氟甲基-1,2,4-三嗪[5,6b]吲哚和5H-1,2,4-三唑[1',5'合成了1,2,3] -1,2,4-三嗪基[5,6b]吲哚衍生物,并通过1H NMR和13C NMR,元素,红外光谱和质谱分析证实了它们的化学结构。评估了这些化合物对恶性疟原虫的氯喹敏感(D10)和耐氯喹(RSA11)菌株的体外抗疟活性。与未取代的类似物相比,在第6位具有三氟甲基的1,2,4-三嗪基[5,6b]吲哚衍生物(4、6和8)表现出更高的体外活性,后者均没有活性。在5H-1,2,4-三唑[1',5',2,3] -1,2,4-三嗪[5,与相应的未取代类似物相比,吲哚环系统产生的化合物的抗疟活性降低。这些化合物与铁原卟啉IX缔合,并或多或少以相同的程度与DNA相互作用。
