Seven second-generation hypoxic markers of the iodinated azomycin nucleoside class have been synthesized and tested for hypoxia marking activity with tumor cells in vitro and in vivo. β-D-lodoazomycin galactoside (IAZG) and β-D-iodoazomycin xylopyranoside (IAZXP) demonstrated superior hypoxia marking properties relative to IAZA because of their higher water solubilities, rapid plasma clearance rates
已经合成了七种二代碘化阿霉素核苷类缺氧标记物,并在体外和体内测试了肿瘤细胞的缺氧标记活性。β-D-碘阿唑霉素半乳糖苷 (IAZG) 和 β-D-碘阿霉素木吡喃糖苷 (IAZXP) 表现出优于 IAZA 的缺氧标记特性,因为它们具有更高的水溶性、从荷瘤小鼠体内快速清除血浆的速度和最大肿瘤/血液 ( /B) 和肿瘤/肌肉 (T/M) 比率。我们对动物肿瘤模型的研究表明,通过闪烁扫描或平面成像确定的这些标志物的 T/B 或 T/M 比率可以预测肿瘤缺氧的相对程度和肿瘤的放射抗性。© 1997 约翰威利父子公司。
