阿霉素 (DXR) 或阿霉素是一种抗肿瘤抗生素,通过链霉菌 (Streptomyces peucetius var caesius) 的有氧发酵或通过道诺霉素的化学合成获得 (Arcamone 等人,1972)。该药物分子显示出两个不同的化学结构域:阿霉素(显示蒽环环结构)和丹糖胺(呈现单个游离氨基的氨基糖),它们通过糖苷键连接在一起。 DXR 表现出显着的抗肿瘤活性(Di Marco 等,1969;Tan 等,1973;Bloomfield 等,1972;O'Brian 等, 1973;Goldin 等,1975),尤其在急性髓性白血病、非霍奇金淋巴瘤以及乳腺癌、肺癌和甲状腺癌的化疗中发挥着核心作用(Young 等,1981)。高剂量 DXR(超过 500 mg/ma 体表面积)的临床使用会因人类患者发生不可逆转的充血性心肌病和心力衰竭而受到严重影响(Lefrak 等,1973)。这种心脏损伤是剂量依赖性的,并且与所施用药物的总累积剂量有关(Henderson 和 Frei,1979)。许多作者表明,静脉输注 DXR 后,接受治疗的个体会出现急性非特异性心电图变化(Lenaz 和 Page,1976 年;Van Hoff 等人,
Doxorubicin (DXR), or adriamycin, is an antitumoral antibiotic, obtained by the aerobic fermentation of Streptomyces peucetius var caesius or by chemical synthesis from daunomycin (Arcamone et al., 1972). The drug molecule displays two different chemical domains: adriamycinone (showing an anthracycline ring structure) and dannosamine (an amino sugar presenting a single free amino group) which are botmd together by a glycosidic bond.DXR exhibits a significant antitumor activity (Di Marco et al., 1969; Tan et al., 1973; Bloomfield et al., 1972; O'Brian et aI., 1973; Goldin et al., 1975) and in particular plays a central role in the chemotherapeutic management of acute myelogenous leukemia, non-Hodgkin's lymphomas, and carcinomas of the breast, lung and thyroid (Young et al., 1981). The clinical use of high doses of DXR (exceeding 500 mg/ma body surface area) is strongly compromised by the development of an irreversible congestive cardiomyopathy and heart failure in human patients (Lefrak et al., 1973). This heart injury is dose-dependent and related to the total cumulative dose of the administered drug (Henderson and Frei, 1979). Many authors have shown that, after intravenous infusion of DXR, acute nonspecific electrocardiographic changes occur in treated individuals (Lenaz and Page, 1976; Van Hoff et al.,
