Bisulphite adducts of compounds of formula
(wherein R represents a group R2-CH-X-(CR4R5)nR3;
R' represents a halogen atom or a trifluoromethyl group;
R2 represents a hydrogen atom or a C1-4 alkyl, C1-4 alkanoyl or phenyl group;
X represents an oxygen or a sulphur atom or a group
, where R6 represents a formyl, C1-4 alkanoyl or C1-4 alkoxycarbonyl group;
R3 represents a C6-10 carbocyclic aromatic group or a heterocyclic group containing a 5- or 6- membered unsaturated heterocyclic ring which ring contains one or more heteroatoms selected from 0, N and S and optionally carries a fused carbocyclic ring, which carbocyclic or heterocyclic group may carry one or more substituents selected from halogen atoms, C1-4 alkyl, C1-4 alkanoyl, C1-4 alkoxy, C1-4 alkoxycarbonyl, C1-4 alkylthio, hydroxyl, nitro, cyano and formyl groups, -NR7R8 groups (where R is a hydrogen atom or a C1-4 alkyl group, and RB is a hydrogen atom or a C1-4 alkyl, C1-4 alkanoyl or aroyl group) and C1-4 alkyl groups substituted by one or more hydroxy or -NR7R8 groups and halogen atoms;
n is an integer having the value 0 or 1; and
R4 and R5, which may be the same or different, each is a hydrogen atom or a C1-6 alkyl group) and salts of such adducts have metaphase arrest abilities and desirably good water solubilities and may be useful in combatting abnormal cell proliferation.
