A number of nitro- and dinitro-1,8-naphthalimides have been prepared as potential fluorescent probes of hypoxic cells. The susceptibility of 4-nitro-1,8-naphthalic anhydrides and -naphthalimides to nucleophilic displacement of the nitro group has been demonstrated by reaction with 1-butanethiol to yield 4-butylthio derivatives. Attempted nitration of these 4-butylthio derivatives with sodium nitrate
已经制备了许多硝基和二硝基-1,8-萘二甲酰亚胺作为缺氧细胞的潜在荧光探针。通过与1-丁硫醇反应生成4-丁硫基衍生物已经证明了4-硝基-1,8-萘酸酐和-萘二甲酰亚胺对硝基的亲核取代的敏感性。用硝酸钠和浓硫酸尝试硝化这些4-丁硫基衍生物,可以高收率得到相应的亚砜。
