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的三嗪衍生物,其化学式为##STR1##其中环A是一个可选取代的芳香基团;X是一个氧原子或硫原子;R.sup.1和R.sup.6分别是氢原子或可选取代的碳氢残基或杂环基团,可以通过杂原子结合;R.sup.2和R.sup.3各自独立地是氢原子、卤素原子或通过碳、氧或硫原子结合的基团,或者一起表示.dbd.S;R.sup.4和R.sup.5各自独立地是氢原子、卤素原子或通过碳、氧、氮或硫原子结合的基团;R.sup.1和R.sup.2,以及R.sup.5和R.sup.6可以结合形成化学键;但是,当环A是一个苯基团,在位置-2或4上至少有一个卤素原子,且X是一个氧原子时,R.sup.4和R.sup.5不结合形成化学键,或其盐。本发明还涵盖了一种抗原虫组合物,包括新的三嗪衍生物或其盐。
