The present invention provides a novel triazine derivative of the formula
wherein ring A is an optionally substituted aromatic group which be;
X is an oxygen or sulfur atom;
R1 and R6 are each a hydrogen atom or an optionally substituted hydrocarbon residue or heterocyclic group which may bound through a hetero-atom;
R2 and R3 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen or sulfur atom, or taken together, represent ═S;
R4 and R5 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen, nitrogen or sulfur atom;
R1 and R2, and R5 and R6, may each bind together to form a chemical bond; provided that where ring A is a phenyl group having at least a halogen atom in position-2 or 4 and X is an oxygen atom, R4 and R5 do not conjoinedly represent a chemical bond and an antiprotozoan composition containing the same or salt thereof.
本发明提供了一种新型三嗪衍生物,其化学式如下:其中环A是可选取代芳基,可以是;X是氧或硫原子;R1和R6分别是氢原子或可选取代的碳氢残基或杂环基,可以通过杂原子结合;R2和R3分别独立地是氢原子、卤素原子或通过碳、氧或硫原子结合的基团,或者一起表示═S;R4和R5分别独立地是氢原子、卤素原子或通过碳、氧、氮或硫原子结合的基团;R1和R2,以及R5和R6,可以结合形成化学键;但当环A是带有2或4号位至少一个卤素原子的苯基且X是氧原子时,R4和R5不能共同表示化学键。还提供了一种含有该三嗪衍生物或其盐的抗原虫组合物。
