A compound for use as an inhibitor for the enzyme dihydroorotase and which is of general formula (I) STR1 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, --NR'R' where each R' is independently selected from --H, saturated or unsaturated C1-16 alkyl, or any group above to be hydrolyzed 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 hydrolyzed 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.

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 C1-16alkyl, C1-16alkyloxymethyl, or 4-alkyl-piperidinyl-alkyl, -NR′R′ where each R′ is independently selected from -H, saturated or unsaturated C1-16alkyl, or any group able to be hydrolysed in vivoto hydroxy;, R3 and R4 which may be the same or different are -H, C1-6alkyl, hydroxy C1-16alkyl, hydroxy C1-6ether group, tetrahydrofuranyl, tetrahydropyranyl, a sugar or acetylated sugar group, hexylcarbamyl, methylglycine-N-carbonyl, or any group able to be hydrolysed in vivoto -H;, R5 is -H, halo, or C1-6alkyl;, R6 is C1-6alkyl 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.

N1,N3-dibenzyloxymethyl derivatives of pyrimidines and dihydropyrimidines have been successfully deprotected by using trifluoroacetic acid (TFA).These N-BOM derivatives can be selectively removed from a variety of derivatives including nucleosides and compounds which are sensitive to base and reducing conditions.
