RSU-1069在离体与整体试验中都表明它是乏氧细胞辐射增敏和生物还原细胞毒性物,但在Ⅰ期试验中观察到毒性较大,为此,合成了一系列稳定的RSU-1069衍生物.它们的主要化学结构如下:
Both in vitro and in vivo tests demonstrated that RSU-1069 is hypoxic cell radiation-sensitizing and bioreductive cytotoxic but has been shown to be more virulent in the Phase I trial. For this reason, a series of stable RSU-1069 Derivatives. Their main chemical structure is as follows:
