    • According to the invention there are provided derivatives of a C21-deoxy ansamycin or salt thereof which contain a 1-hydroxyphenyl moiety bearing at position 3 an aminocarboxy substituent, in which position 5 and the aminocarboxy substituent at position 3 are connected by an aliphatic chain of varying length characterised in that the 1-hydroxy position of the phenyl ring is derivatised by an aminoalkyleneaminocarbonyl group, which alkylene group (which may optionally be substituted by alkyl groups) has a chain length of 2 or 3 carbon atoms, a phosphoric acid, or a phosphoric acid ester (such as an alkyl ester) group, or a salt thereof, and which derivatising group increases the water solubility and/or the bioavailability of the parent molecule. Such compounds are useful in therapy eg in the treatment of cancer and B-cell malignancies.
    • 根据本发明,提供了一种C21-脱氧安莎霉素或其盐的衍生物,其含有在位置3具有氨基羧基取代基的1-羟基苯基部分,其中位置5和位置3上的氨基羧基取代基通过脂族链连接 变化的长度,其特征在于苯环的1-羟基位置被氨基亚烷基氨基羰基衍生,该亚烷基(其可以任选被烷基取代)具有2或3个碳原子的链长,磷酸或 磷酸酯(例如烷基酯)或其盐,并且该衍生基增加了母体分子的水溶性和/或生物利用度。 这样的化合物可用于治疗,例如治疗癌症和B细胞恶性肿瘤。
