Abstract
A compound of formula (I): ##STR1## wherein R.sup.1 represents a hydrogen or halogen atom, or a cyano group; PA1 R.sup.2 represents an optionally substituted carbocyclic group having 6 to 10 ring atoms and containing at least one aromatic ring; an optionally substituted heterocyclic group having 5 to 10 ring atoms, including 1 to 4 heteroatoms selected from O, N and S, and containing at least one aromatic ring; or an optionally substituted C.sub.3-6 cycloalkyl, C.sub.3-6 cycloalkyl- C.sub.1-6 alkyl, or C.sub.1-10 alkyl group; PA1 R.sup.3 and R.sup.4, which may be the same or different, each represent a hydrogen or halogen atom, or a C.sub.1-6 alkyl group optionally substituted by 1 to 3 halogen atoms; and PA1 R.sup.5 represents a hydrogen atom, a hydroxyl group, or a C.sub.1-6 alkyl group, optionally substituted by hydroxy, carboxy, amino or mono- or di-(C.sub.1-4)alkyl amino, and salts and other physiologically functional derivative thereof. The compounds are useful in the treatment of parasitic infections eg. malaria, coccidiosis and Pneumocystis carinii pneumonia.
