Hitting the hypoxic target: Combining a nitro prodrug with a water‐soluble phosphate converts duocarmycin analogues from highly toxic DNA‐alkylating agents to highly selective antitumor compounds. These prodrugs (see scheme) have outstanding activity against hypoxic tumor cells in vivo, cells which are usually considered the most resistant to conventional therapy.
达到缺氧目标:将硝基前药与水溶性磷酸酯结合使用,可以将杜卡霉素类似物从剧毒的DNA烷基化剂转化为高度选择性的抗肿瘤化合物。这些前药(参见方案)在体内对缺氧肿瘤细胞具有出色的活性,这些细胞通常被认为对常规疗法最有抵抗力。
