There are provided inter alia derivatives of a benzenoid ansamycin which contain a 1,4-dihydroxyphenyl moiety bearing at position 6 an amino carboxy substituent, in which position 2 and the carboxy substituent at position 6 are connected by an aliphatic chain of varying length characterised in that one or both of the 1-hydroxy and the 4-hydroxy position(s) of the phenyl ring are independently derivatised by an aminoalkyleneaminocarbonyl group, which alkylene group, which may optionally be substituted by alkyl groups, has a chain length of 2 or 3 carbons and which derivatising group(s) increase the water solubility and/or the bioavailability of the parent molecule but which are capable of being removed in-vivo. Such compounds are described for the treatment of cancer or B-cell malignancies.
