Synthesis of a 3′-naphthamido-LacNAc fluorescein conjugate with high selectivity and affinity for galectin-3
摘要:
Described is the synthesis of a fluorescent LacNAc derivative appended with a 3-deoxy-3'-naphthamido functionality, 2-(fluorescein-5/6-amido)ethyl 3-deoxy-3-(2-naphthamido)-beta-D-galactopyranosyl-(1 -> 4)-2-acetamido-2-deoxy-beta-D-glucopyranoside, which confers high affinity (K-d 170 nM) and selectivity for galectin-3 via a stacking interaction with Arg144. Its use as a selective and sensitive galectin-3 probe is demonstrated with fluorescence polarization measurements. (c) 2006 Elsevier Ltd. All rights reserved.
