Alkaline phospholipase (ALP)—a hydrolase associated with many cancers and is widely distributed in human organs—has been recognized as an important biomarker in several medical and biological fields. In order to better detect and image ALP, we constructed a novel ratiometric fluorescent probe—APW—that can respond quickly (in less than 15 minutes) with high quantum yield (Φ = 0.6) and sensitivity (its
碱性磷脂酶(ALP)是一种与许多癌症相关的水解酶,广泛分布于人体器官中,已被认为在许多医学和生物领域中都是重要的生物标志物。为了更好地检测ALP并对其成像,我们构建了一种新颖的比率式荧光探针APW,该探针可以快速(在不到15分钟的时间内)以高量子产率(Φ = 0.6)和高灵敏度(检测极限为0.46 UL -1)响应)到ALP。我们的研究具有重大意义,因为它使用了鲜有报道的新的比率响应方法,从而大大缩短了响应时间。此外,我们成功地将这种新型探针应用于细胞成像,并获得令人满意的结果。
