The present invention relates to the use of caffeic acid or a derivative thereof represented by the following general formula (1)
wherein
X is O, NH, or heterocyclyl;
R may be present or absent and if present, is H, alkyl, aryl, or heterocyclyl;
in all its stereoisomeric and tautomeric forms, and mixtures thereof in all ratios, and a pharmaceutically acceptable salt, pharmaceutically acceptable solvate, pharmaceutically acceptable polymorph or a prodrug, in the treatment of chronic myeloid leukemia (CML) which is resistant to treatment with GLEEVEC. The invention also relates to a method for reducing the proliferation of cells that are resistant to GLEEVEC by contacting the cells with a compound of general formula (1). The present invention also relates to pharmaceutical compositions (for the manufacture of the medicament) including caffeic acid or a derivative or a salt thereof represented by the general formula (1) for the treatment of chronic myeloid leukemia (CML) that is resistant to treatment with GLEEVEC, or for reducing the proliferation of cells that are resistant to GLEEVEC. The present invention further relates to a method of treatment of chronic myeloid leukemia (CML) that is resistant to treatment with GLEEVEC.
本发明涉及使用咖啡酸或其衍生物在治疗对GLEEVEC治疗具有抗药性的慢性髓细胞白血病(CML)方面的应用,该衍生物由以下通式(1)表示:
其中X为O、NH或杂环基;R可以存在或不存在,如果存在,则为H、烷基、芳基或杂环基;在其立体异构体和互变异构体形式中,以及在所有比例的混合物中,以及药学上可接受的盐、药学上可接受的溶剂化合物、药学上可接受的多晶形或前药。本发明还涉及通过接触一般式(1)的化合物来减少对GLEEVEC具有抗药性的细胞的增殖的方法。本发明还涉及包括咖啡酸或一般式(1)所表示的其衍生物或其盐的制药组合物(用于制造药物),用于治疗对GLEEVEC治疗具有抗药性的慢性髓细胞白血病(CML)或减少对GLEEVEC具有抗药性的细胞的增殖。本发明还涉及治疗对GLEEVEC治疗具有抗药性的慢性髓细胞白血病(CML)的方法。
