This invention provides, among other things, novel compounds useful for treating protozoal infections, pharmaceutical compositions containing such compounds, as well as combinations of these compounds with at least one additional therapeutically effective agent. The exemplary compounds have the following formula:
wherein X is selected from the group consisting of substituted phenyl, substituted or unsubstituted heteroaryl and unsubstituted cycloalkyl; R3a is selected from the group consisting of H, unsubstituted C1 or C2 or C3 or C4 or C5 or C6 alkyl and unsubstituted C3 or C4 or C5 or C6 cycloalkyl; R3b is selected from the group consisting of H, unsubstituted C1 or C2 or C3 or C4 or C5 or C6 alkyl and unsubstituted C3 or C4 or C5 or C6 cycloalkyl;
with the proviso that R3a and R3b, along with the atom to which they are attached, are optionally joined to form a 3 or 4 or 5 or 6 membered ring, with the proviso that R3a and R3b cannot both be H, or a salt thereof.
该发明提供了用于治疗原虫感染的新化合物,包含这些化合物的药物组合物,以及这些化合物与至少一种其他治疗有效的药物的组合。示例化合物的化学式如下:其中X选择自取代苯基、取代或未取代杂环芳基和未取代环烷基的群体;R3a选择自H、未取代C1或C2或C3或C4或C5或C6烷基和未取代C3或C4或C5或C6环烷基的群体;R3b选择自H、未取代C1或C2或C3或C4或C5或C6烷基和未取代C3或C4或C5或C6环烷基的群体;但R3a和R3b与它们所连接的原子可以选择结合形成3、4、5或6元环,但R3a和R3b不能同时为H,或其盐。
