MONOSACCARIDES, PHARMACEUTICAL COMPOSITIONS, AND DIAGNOSTIC AND THERAPEUTIC APPLICATIONS
摘要:
Provided herein are monosaccharides, e.g., a compound of Formula (I), and pharmaceutical compositions thereof. Also provided herein are methods of their use for cell labeling for diagnostic and/or therapeutic applications.
carbohydrate-neuroactive hybrid (CNH) molecules, which exploit carrier-mediated transport systems available at the blood-brain barrier, to access brain via tail vein injection in mice. Peracetylated N-azidoacetyl-d-mannosamine (Ac4ManNAz) conjugated with neuroactive carriers, namely, nicotinic acid, valproic acid, theophylline-7-acetic acid, and choline, were synthesized and evaluated in SH-SY5Y (human neuroblastoma)

Metabolic glycoengineering of unnatural glycans with bio-orthogonal chemical groups and a subsequent click reaction with fluorescent probes have been widely used in monitoring various bioprocesses. Herein, we developed a dual-responsive metabolic precursor that could specifically generate unnatural glycans with azide groups on the membrane of targeted cancer cells with high selectivity. Moreover, a
具有生物正交化学基团的非天然聚糖的代谢糖工程和随后与荧光探针的点击反应已广泛用于监测各种生物过程。在本文中,我们开发了一种双重反应的代谢前体,可以特异性地在目标癌细胞的膜上生成具有叠氮基的非天然聚糖。此外,还合成了具有聚集诱导发射(AIE)的水溶性荧光发光探针,该探针在与癌细胞表面上叠氮化物基团发生点击反应后便会发出荧光,从而能够以低背景信号进行特殊的癌细胞成像。此外,探针可以产生1 O 2在光照射下,可以发挥其作为癌细胞成像和治疗剂的双重作用。因此,癌细胞特异性代谢前体cRGD–S-Ac 3 ManNAz和AIE发光探针的概念在生物正交标记以及癌症特异性成像和治疗中很有前途。
