O2-phosphorylation has so far not been reported yet. Herein, we describe the design, synthesis and biological evaluation of a group of phosphorodiamidate mustard-based O2-phosphorylated diazeniumdiolates, 6–9. The most active compound, 7, was comparable, or even more potent, than a known anticancer agent, O2-2,4-dinitrobenzene diazeniumdiolate JS-K, against six cancer cell lines. Furthermore, 7 released larger amounts
一氧化氮(NO)最近加入了癌症治疗的临床领域,因为高水平的NO不仅会诱导癌细胞的细胞毒性和凋亡,而且会使细胞对化学疗法和放射疗法敏感。二醇二氮烯鎓是一类重要的NO供体,二醇二氮烯鎓的O 2-烷基化,芳基化和磺酰化可产生更稳定和有效的抗癌药。然而,迄今为止尚未报道O 2-磷酸化。在这里,我们描述了一组基于磷酸二酰胺基芥子油的O 2-磷酸化二氮烯二醇盐6-9的设计,合成和生物学评估。活性最高的化合物7与已知的抗癌药O 2 -2,4-二硝基苯二氮杂二烯二醇盐JS-K相比,它对六种癌细胞系具有甚至更高的作用。此外,在癌细胞中,有7种释放出的NO数量比JS-K引起更大的DNA损伤和癌细胞凋亡。我们的研究结果表明,这种新型的O 2取代的二氮杂二烯二醇盐可能会潜在地用于抗癌。
