The present invention relates to anthracycline derivatives that are based on an Aloe-emodin (AE) backbone attached to a glycoside (an amino sugar or amino carba-sugar). These derivatives are useful as chemotherapeutic agents. Advantageously, these derivatives are potent cytotoxic agents against a variety of anthracycline-resistant tumors. In addition, they may have reduced cardiotoxicity. As such, the novel compounds of the invention offer an advantage over currently available drugs. The present invention further relates to methods for preparing the novel Aloe-Emodin Glycoside (AEG) based derivatives, pharmaceutical compositions including such compounds, and methods of using these compounds and compositions, especially as chemotherapeutic agents for prevention and treatment of cancers.
本发明涉及基于芦荟大黄素(AE)骨架与糖苷(氨基糖或氨基卡巴糖)相连的蒽环类衍生物,这些衍生物可用作化疗药物。这些衍生物对多种蒽环类耐药肿瘤具有强效的细胞毒性作用。此外,它们可能具有较低的心脏毒性。因此,本发明的新化合物比目前可用的药物具有优势。本发明还涉及制备新的芦荟大黄素糖苷(AEG)衍生物的方法,包括这些化合物的制药组合物,以及使用这些化合物和组合物的方法,特别是作为预防和治疗癌症的化疗药物。
