ABSTRACT
In this work, we developed a dual-targeting probe consisted of well-defined hyaluronan (HA) oligosaccharide and glucose (Glc) labeled with Rhodamine B (HGR). The probe was designed to enhance tumor targeting both in vitro and in vivo, by simultaneously targeting CD44 and Glc transporter 1 (GLUT1). The HA oligosaccharide component was crucial for accurately assessing the impact of sugar chain structure on targeting efficacy, while its unoccupied carboxyl groups could minimize interference with HA's binding affinity to CD44. In vitro studies demonstrated that HGR possessed remarkable cytocompatibility and superior targeting abilities compared to single-targeting probes. It displayed a marked preference for CD44high/GLUT1high cells rather than CD44low/GLUT1low cells. In vivo studies using murine models further confirmed the significantly enhanced targeting efficacy and excellent biocompatibility of HGR. Therefore, this designed dual-targeting probe holds potential for clinical tumor detection.
