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.

Attachment of p-benzophenone side chains at N1 was found to be one of the most effective modifications for enhancing the potency of 6-azauracil against a broad spectrum of coccidia in chickens. Compound 20 was about 1000-fold more potent than 6-azauracil. Structure-activity relationships paralleled those found in a previously reported series of related analogues containing diphenyl sulfide and sulfone
