A compound for use as an inhibitor for the enzyme dihydroorotase and which is of general formula (I)
where either (i) A and B together are =S
or (ii) A is -H, and B is -COR₂ or -SR₆; and
R₁ and R₂ which may be the same or different are -OH; alkyloxymethyl, a di-, tri- or polypeptide group, -OR where R is saturated or unsaturated C1-16 alkyl, C1-16 alkyloxymethyl, or 4-alkyl-piperidinyl-alkyl, -NRʹRʹ where each Rʹ is independently selected from -H, saturated or unsaturated C1-16 alkyl, or any group able to be hydrolysed in vivo to hydroxy;
R₃ and R₄ which may be the same or different are -H, C1-6 alkyl, hydroxy C1-16 alkyl, hydroxy C1-6 ether group, tetrahydrofuranyl, tetrahydropyranyl, a sugar or acetylated sugar group, hexylcarbamyl, methylglycine-N-carbonyl, or any group able to be hydrolysed in vivo to -H;
R₅ is -H, halo, or C1-6 alkyl;
R₆ is C1-6 alkyl or 1-methyl-4-nitroimidazol-5-yl; and the dotted line represents a double bond which may be absent or present in the 4-5 position. The compounds are useful as anti-cancer and anti-malarial drugs.
