  • Patent number: 5604237
    Abstract: These are provided compounds of formula I ##STR1## wherein A represents an oxygen or a sulphur atom, a bond or a group (CH.sub.2).sub.1 NR.sup.9 (where 1 represents zero or 1 and R.sup.9 represents a hydrogen atom or a methyl group); B represents a C.sub.1-4 alkylene chain optionally substituted by a hydroxyl group, except that the hydroxyl group and moiety A can not be attached to the same carbon atom when A represents an oxygen or sulphur atom or a group (CH.sub.2).sub.1 NR.sup.9, or when A represents a bond B may also represent a C.sub.2-4 alkenylene chain; R.sup.3 represents a hydrogen atom or a C.sub.1-4 alkyl group; m represents 1 or 2; R.sup.7 represents a hydrogen atom or R.sup.3 and R.sup.7 together form a group --(CH.sub.2).sub.n -- where n represents 1 or 2. These compounds can sensitize multidrug-resistant cancer cells to chemotherapeutic agents and may be formulated for use in therapy, particularly to improve or increase the efficacy of an antitumor drug.
