Mono- and bis-N-oxides of a 9-aza-anthrapyrazole derivative having two 2-(dimethylamino)ethyl appendages were prepared by using a mild oxaziridine reagent. Biochemical and cell culture assays indicate that the bis-oxide is an inactive prodrug that readily converts to the active parent molecule under hypoxic conditions that are analogous to those present within certain tumors.
用温和的氮氧化物试剂制备了具有两个 2-（二甲基氨基）乙基附加物的 9-氮杂蒽并吡唑衍生物的单-和双-N-氧化物。生化和细胞培养试验表明，双氧化物是一种无活性的前药，在类似于某些肿瘤中存在的缺氧条件下，很容易转化为活性母体分子。
