The present invention provides a novel triazine derivative of the formula ##STR1## wherein ring A is an optionally substituted aromatic group; X is an oxygen or sulfur atom; R.sup.1 and R.sup.6 are each a hydrogen atom or an optionally substituted hydrocarbon residue or heterocyclic group which may bound through a hetero-atom; R.sup.2 and R.sup.3 are each independently a hydrogen atom, a halogen atom, or a group bound through a carbon, oxygen or sulfur atom, or taken together, represent .dbd.S; R.sup.4 and R.sup.5 are each independently a hydrogen atom, a halogen-atom, or a group bound through a carbon, oxygen, nitrogen or sulfur atom; R.sup.1 and R.sup.2, and R.sup.5 and R.sup.6 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, R.sup.4 and R.sup.5 do not conjoin to form a chemical bond, or a salt thereof. The invention also encompasses an antiprotozoan composition comprising the novel triazine derivative or a salt thereof.
本发明提供了一种新型的三嗪衍生物,其化学式为##STR1##其中环A是一个可选择取代的芳香基团;X是一个氧原子或硫原子;R^1和R^6分别是氢原子或可选择取代的碳氢残基或杂环基,可以通过一个杂原子连接;R^2和R^3分别独立地是氢原子、卤素原子或通过碳、氧或硫原子连接的基团,或者一起表示.dbd.S;R^4和R^5分别独立地是氢原子、卤素原子,或通过碳、氧、氮或硫原子连接的基团;R^1和R^2,以及R^5和R^6可以分别结合形成一个化学键;但是在环A是一个苯基,位置-2或4至少有一个卤素原子,X是氧原子时,R^4和R^5不能结合形成化学键,或其盐。该发明还包括一种抗原虫组合物,包括上述新型三嗪衍生物或其盐。
