    • 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.
    • 这些是式I化合物其中A表示氧或硫原子,键或基团(CH 2)1 NHR 9(其中1表示0或1,R 9表示氢原子或 甲基); B表示任选被羟基取代的C 1-4亚烷基链,除了当A表示氧或硫原子或基团(CH 2)1 NHR 9时,羟基和A部分不能连接到相同的碳原子上,或者当 A表示键B也可以表示C2-4亚链烯基; R3表示氢原子或C1-4烷基; m表示1或2; R7代表氢原子或R3和R7一起形成基团 - (CH 2)n - ,其中n表示1或2.这些化合物可使多重耐药性癌细胞对化学治疗剂敏感,并可配制用于治疗,特别是改善 或增加抗肿瘤药物的功效。
