ABSTRACT:
Compounds of the formula ##STR1## (wherein X represents a halogen atom; n is 0, 1 or 2; R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom or a carboxyl, esterified carboxyl, amido or mono- or di-C.sub.1-4 alkylamido group or a C.sub.1-4 alkyl group which may if desired carry a carboxyl or esterified carboxyl group; and R.sup.3 represents a C.sub.1-32 saturated or unsaturated, straight or branched, cyclic or acyclic aliphatic group or an araliphatic or heterocyclic substituted aliphatic group, a heterocyclic group or an aryl group which groups may if desired carry one or more substituents selected from halogen atoms and oxo, nitro, hydroxy, etherified hydroxy, esterified hydroxy, primary, secondary or tertiary amino, acylamino etherified mercapto or S.dbd.O or --SO.sub.2 derivatives thereof and esterified phosphonic acid groups) and, where an acidic or basic group is present, physiologically compatible salts thereof have been found to be of use in combating abnormal cell proliferation. The compounds are prepared inter alia by oxidation of the corresponding sulfide, displacement of a leaving atom or group from the 2-position of the pyrimidine by reaction with a sulfinic acid or by ring closure of the pyrimidine ring.
