Parasiticidal pyrazoles

Compounds of formula (I) or pharmaceutically, veterinarily or agriculturally acceptable salts thereof, or pharmaceutically, veterinarily or agriculturally acceptable solvates of either entity, wherein R1 is 2,4,6-trisubstituted phenyl or 3,5-disubstituted pyridin-2-yl; R3 is C1 -C4 alkyl optionally substituted with hydroxy or with one or more halo; cyano, C1 to C5 alkanoyl or phenyl; R5 is hydrogen, C1 to C4 alkyl, amino or halo; R2 and R4 are each independently selected from hydrogen, C1 to C4 alkyl, fluoro, chloro and bromo or, together with the carbon atom to which they are attached, form a C3 to C6 cycloalkyl group; R6 and R8 are each independently selected from hydrogen, C1 to C4 alkyl, fluoro, chloro and bromo; or, when R2 and R4 do not form part of a cycloalkyl group, R2 and R6, together with the carbon atoms to which they are attached, may form a C5 to C7 cycloalkyl group; and R7 is hydrogen, C1 to C4 alkyl optionally substituted with one or more halo, or C1 to C4 alkoxy; are parasiticidal agents.
