    • New use for compounds, compositions and methods are provided for treating malaria parasites in vitro and in vivo by administering indolo[2,1-b]quinazoline-6,12-dione compounds of Formula (I), wherein A, B, C, D, E, F, G and H are independently selected from carbon and nitrogen, or A and B or C and D can be taken together to be nitrogen or sulfur, with the proviso that not more than three of A, B, C, D, E, F, G and H are other than carbon; wherein R1 through R8 are independently selected from the group consisting of, but not limited to, the halogens (F, Cl, Br, and I), alkyl groups, trifluoromethyl groups, methoxyl groups, the carboxy methyl or carboxy ethyl group (COOCH3 or COOCH2CH3), nitro, aryl, heteroaryl, cyano, amino, dialkylaminoalkyl, 1-(4-alkylpiperazinyl), and the pharmaceutically acceptable salts thereof; and wherein X is independently selected from the group consisting of any atom especially oxygen, or any side chain necessary to make the indolo[2,1-b]quinazoline-6,12-dione compound a "prodrug" as the term is understood by one of ordinary skill in the art of medicinal chemistry. In other words, a side chain having a structure where a carbon-nitrogen double bond bears substituents that make the prodrug more water soluble and bioavailable.
    • 提供了通过施用式(I)的吲哚并[2,1-b]喹唑啉-6,12-二酮化合物在体外和体内治疗疟疾寄生虫的化合物,组合物和方法的新用途,其中A,B,C, D,E,F,G和H独立地选自碳和氮,或者A和B或C和D可以合在一起形成氮或硫,附带条件是A,B,C, D,E,F,G和H不是碳; 其中R 1至R 8独立地选自但不限于卤素(F,Cl,Br和I),烷基,三氟甲基,甲氧基,羧甲基或羧乙基(COOCH 3或 硝基,芳基,杂芳基,氰基,氨基,二烷基氨基烷基,1-(4-烷基哌嗪基)及其药学上可接受的盐; 并且其中X独立地选自由任何原子特别是氧原子或任何制备吲哚并[2,1-b]喹唑啉-6,12-二酮化合物所必需的侧链,该术语可理解为“前药” 药物化学领域的普通技术人员之一。 换句话说,具有碳 - 氮双键带有取代基的结构的侧链使得前药更易溶于水且具有生物利用度。
