The present invention relates to compounds represented by the formula:
wherein ring H represents an optionally substituted aromatic heterocyclic group or an optionally substituted alicyclic hydrocarbon group; X and Y independently represent a single bond, —O—, a group of the formula: —S(O)m— wherein m is 0, 1 or 2, a group of the formula: —NR8— wherein R8 represents a hydrogen atom, an alkyl group or an acyl group, —CO— or an optionally substituted methylene group; —A—B— represents —N═CH—, —CH═N—, —N═N— or —CH═CH—; R1 represents a hydrogen atom, a halogen atom, an optionally substituted alkyl group which may be bonded through a hetero atom or an acyl group; R2 and R3 independently represent a hydrogen atom, a halogen atom or an optionally substituted alkyl group; R4 represents a hydrogen atom or a halogen atom; R5 represents a hydrogen atom, an optionally substituted alkyl group or an acyl group; R6 and R7 independently represent a hydrogen atom or R6 and R7 may form a chemical bond together with each other; and D represents —CH2— or —CO—; or a salt thereof. These compounds and salts thereof are useful as anti-protozoal agents.
本发明涉及由下式表示的化合物:其中环H代表可选择地取代的芳香杂环基团或可选择地取代的脂环烃基团;X和Y分别表示单键,—O—,具有下式的基团:—S(O)m—其中m为0、1或2,具有下式的基团:—NR8—其中R8代表氢原子、烷基或酰基,—CO—或可选择地取代的亚甲基基团;—A—B—代表—N═CH—,—CH═N—,—N═N—或—CH═CH—;R1代表氢原子、卤原子、可选择地取代的烷基基团(可以通过杂原子键合)或酰基;R2和R3分别代表氢原子、卤原子或可选择地取代的烷基基团;R4代表氢原子或卤原子;R5代表氢原子、可选择地取代的烷基基团或酰基;R6和R7分别代表氢原子或R6和R7可以彼此之间形成化学键;D代表—CH2—或—CO—;或其盐。这些化合物及其盐可用作抗原虫药物。
