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 heteroatom;
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,其式为
其中环 A 是任选取代的芳香基团,该芳香基团是
X是氧原子或
硫原子
R1和R6各自是氢原子或可通过杂原子结合的任选取代的烃残基或杂环基团;
R2 和 R3 各自独立地为氢原子、卤素原子或通过碳原子、氧原子或
硫原子结合的基团,或合在一起代表 = S;
R4 和 R5 各自独立地为氢原子、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 可各自结合在一起形成
化学键;但当环 A 是在第 2 位或第 4 位至少有一个卤素原子的苯基且 X 是氧原子时,R4 和 R5 不连在一起代表
化学键以及含有相同成分或其盐的抗原虫组合物。
