Abstract
Description
Technical Field
[0001] The present invention relates to the field of biomedicine technology, and in particular to an NQO1-responsive lysosome rapid targeting optical probe and a preparation method and application thereof. Background Art
[0002] Among many biomarkers of cancer, the design of optical probes for targeted activation of highly active proteases that are closely related to cancer progression has become a research hotspot. Enzyme-responsive activatable optical probes provide possible technologies for cancer diagnosis and high-precision resection of cancer tissues. Among them, quinone oxidoreductase 1 (NADH / NADPH: quinoneoxidoreductase 1, NQO1) is an enzyme present in the human body that regulates oxidative stress of chromatin-bound proteins to DNA damage in cancer cells. Compared with normal human cells, it is known to be overexpressed in various tumor cells of the breast, lung, cervix, pancreas and colon. At the same time, NQO1 can inhibit the development of cancer cells by inhibiting the activation of oncogenic metabolism and preventing the formation of carcinogens through the mechanism of NADPH reducing FAD to form FADH2.
[0003] Meanwhile, organelle-specific targeted delivery has emerged as a promising approach in the field of drug delivery and therapy. This innovative strategy involves the precise delivery of therapeutic drugs to specific organelles within cells, such as the nucleus, mitochondria, endoplasmic reticulum, or lysosomes, with the goal of enhancing drug efficacy while minimizing off-target effects. Among the many organelles, lysosomes are considered regulators of homeostasis in organisms and cells, and are important in mediating signal transduction, cell proliferation, cell differentiation, and so on. Alterations and on-target dysfunction of lysosomes have a profound impact on the progression of cancer.
[0004] Therefore, this application designs and develops an optical probe that can selectively activate enzymes with high expression in tumor cells. Relying on the advantage of rapid organelle positioning, it is expected to provide valuable reference for visual cancer treatment that achieves precise tumor positioning and organelle targeted regulation. Summary of the invention

The probe can specifically identify the NQO1 enzyme overexpressed in tumor cells, can basically distinguish cancer cells from normal cells, and realize the preliminary diagnosis of the tumor site.

[0066] Relying on the overexpression of NQO1 in cancer cells, the performance of TPA-BN-Q in distinguishing cancer cells from normal cells that do not express NQO1 in an in vitro biological environment was further explored. Cancer cells (Ags, DU145, MIA, MCF-7, HeLa) and normal cells (HUVEC, 7702) were divided into three groups, incubated with culture medium, 10μg / mL TPA-BN-Q and 20μg / mL TPA-BN-Q for 1 hour, washed with PBS, stained with Hoechst 33342 fluorescent dye (10μg / mL) for 15 minutes, and imaged under a confocal microscope after washing. The results showed that brighter red fluorescence signals were produced in cancer cells compared with normal cells, indicating that TPA-BN-Q can specifically distinguish cancer cells that overexpress NQO1.
[0067] Example 6: Fluorescence imaging and quantitative analysis of the specific response of TPA-BN-Q to intracellular NQO1
[0068] Based on the fact that TPA-BN-Q can achieve a highly sensitive response to NQO1 in the solution phase, the specific response to NQO1 in cancer cells was further explored. Cancer cells (Ags, DU145, MIA, MCF-7, HeLa) and normal cells (HUVEC, 7702) were divided into two groups. One group was pre-treated with 100μM dicoumarol for 1h, washed with PBS, incubated with 20μg / mL TPA-BN-Q for 1h, and then stained with Hoechst 33342 fluorescent dye (10μg / mL) for 15min. The control group was incubated with 20μg / mL TPA-BN-Q for 1h and then stained with Hoechst 33342 fluorescent dye (10μg / mL) for 15min, and then imaged directly under a confocal microscope. The results showed that the red fluorescence signal in the cells after dicoumarol treatment was significantly weakened compared with the control group, indicating that TPA-BN-Q can achieve a specific response to NQO1 in the cells.
[0069] In summary, the NQO1-responsive lysosome-targeted optical probe (TPA-BN-Q) of the present invention can quickly locate lysosomes in tumors and undergo intramolecular cyclization reaction with the NQO1 enzyme overexpressed in tumor cells, resulting in the cleavage of the trimethyl lock, thereby releasing the intermediate TPA-BN with a strong fluorescent signal. The probe can specifically identify the NQO1 enzyme overexpressed in tumor cells, can basically distinguish cancer cells from normal cells, and achieve preliminary diagnosis of tumor sites. At the same time, the material has low dark toxicity, greatly reducing damage to normal tissues.
