本文报道了2,7-二氯荧光素甲酯(DCF-ME)的晶体结构及其对羟基磷灰石结合的荧光响应。已报道的荧光团对骨基质的染色具有很高的选择性,并在羟基磷灰石结合时提供开启的荧光。报道的荧光团可以很容易地通过C2C12细胞系的细胞膜,对细胞系无毒。已报道的荧光团DCF-ME可能会应用于监测骨骼重塑和微钙化,作为乳腺癌和老年性黄斑变性的早期诊断工具。
Herein, we report the crystal structure of 2,7-dichlorofluorescein methyl ester (DCF-ME) and its fluorescence response to hydroxyapatite binding. The reported fluorophore is very selective for staining the bone matrix and provides turn-on fluorescence upon hydroxyapatite binding. The reported fluorophore can readily pass the cell membrane of the C2C12 cell line, and it is non-toxic for the cell line. The reported fluorophore DCF-ME may find applications in monitoring bone remodeling and microcalcification as an early diagnosis tool for breast cancer and age-related macular degeneration.
