  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.

  提供了苯并氨基甲酸衍生物，其中包含一个在6号位带有氨基羧基取代基的1,4-二羟基苯基基团，其中2号位和6号位的羧基取代基由不同长度的脂肪链连接，其特征在于苯环的1-羟基和/或4-羟基位置独立地被氨基烷基氨基羧基基团衍生化，该烷基，可以选择性地被烷基取代，具有2或3个碳原子的链长，该衍生化基团增加了母体分子的水溶性和/或生物利用度，但在体内可以被去除。这些化合物用于治疗癌症或B细胞恶性肿瘤。

  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.
