The invention relates to a family of fluorescent compounds that comprise a bridged polycyclo moiety. The compounds can be chemically linked to biomolecules, such as proteins, nucleic acids, and therapeutic small molecules. The compounds can be used for imaging in a variety of medical, biological and diagnostic applications, and are particularly useful for the in vivo imaging of regions of interest within a mammal.
responsive fluorescentprobe, which can detect the presence of wide variety of CESs, may provide overall or category information from another point of view, supplementing the deficiency of single detection for CES subspecies. Organelle lysosome is involved in various cell processes, such as cell signaling, apoptosis, secretion, and energy metabolism. Up to date, lysosome-targeted fluorescentprobes, especially
可在线获取 羧酸酯酶(CES)表达异常与高脂血症、动脉粥样硬化、肥胖、肝癌、2型糖尿病和胃肠道间质瘤等多种疾病密切相关。实际样品中单一酶的检测通常受到 CES 结构多样性的限制。因此,开发可检测多种CES存在的广谱羧酸酯酶响应荧光探针,可以从另一个角度提供整体或类别信息,补充单一检测CES亚种的不足。细胞器溶酶体参与各种细胞过程,例如细胞信号传导、细胞凋亡、分泌和能量代谢。迄今为止,溶酶体靶向荧光探针,尤其是那些具有红色发射(超过 550 nm,具有相对较低的生物危害性),对于 CES 检测仍然很少见。溶酶体靶向红色荧光探针 CES-Lyso 被设计用于监测细胞内多种羧酸酯酶的变化,具有极好的选择性和灵敏度,进一步应用于区分不同来源的乳腺癌细胞和监测抗癌药物治疗中的羧酸酯酶活性。

Compounds and methods are disclosed that are useful for noninvasive imaging in the near-infrared (NIR) spectral range. The NIR is highly sensitive for tumor detection and tracking. The application discloses targeting a tumor-enriched cell surface receptor with a ligand-conjugated fluorescent probe, which specifically allows detection of the tumor relative to the negligible animal autofluorescence.
