Mitochondria play crucial roles in a variety of cellular physiological processes, mitochondria-accumulating drug delivery has drawn pronounced attention in the field of cancer theranostics. Camptothecin (CPT) is a DNA Topoisomerase I inhibitor and exerts a broad-spectrum anticancer profile. Berberine (BBR) is able to perferably enter into cancer cell mitochondria and trigger the cell apoptosis. In this work, CPT and BBR were combined together (CPT-ss-BBR) through GSH-responsible disulfide bond, and then co-assembled with photosensitizer indocyanine green (ICG) into nanodrugs (CPT-ss-BBR/ICG NPs), which was driven through hydrophobic, π-π stacking and especially, electrostatic interactions of anions and cations as found by molecular dynamics simulations and quantum chemistry calculations. Our developed nanodrugs displayed an average size of ~168 nm and showed exceptional instability by irradiation presence, acid condition and high concentration of GSH, thereby eliciting the rapid disassembly and accelerating drug release. The better therapy effect of CPT-ss-BBR/ICG NPs on A549 cells might be attributed to triply stimuli-responsive rapid disassembly, preferable accumulation into mitochondria and combined chemotherapy and photothermal therapy, all of which directly rendered the notable loss of mitochondria membrane potential, high level of reactive oxygen species in cancer cells, accelerated the apoptosis of cancer cells and repressed the growth of tumors.

Hydrazine in water and soil has caused serious diseases that threaten human health. It is critical to develop a simple and effective method for hydrazine detection. In this work, a simple fluorescent probe (BP) for hydrazine detection was synthesized from the isoquinoline alkaloid berberine. The probe has a short synthesis route (2 steps), low detection limit (1.37 μM), excellent fluorescence properties, and convenient naked-eye detection. In addition, BP displayed excellent selectivity and specificity over other metal ions, anions, and amines. Moreover, BP was also successfully used to detect hydrazine gas at different concentrations.

Dual-channel berberine-based fluorescent probe for detecting Hg/ClO as well as preparation method and application thereof
-
Paragraph 0026-0030, (2020/07/06)
The invention discloses a dual-channel berberine-based fluorescent probe for detecting Hg/ClO as well as a preparation method and application of the dual-channel berberine-based fluorescent probe. According to the invention, berberine is used as a raw material to prepare the dual-channel berberine fluorescent probe for detection of Hg/ClO. Berberine hydrochloride 1 is subjected to methoxy and chloride ion removal to obtain a ketone compound 2; the compound 2 is acidified and isomerized to obtain a phenolic compound 3; Duff formylation reaction is carried out on the compound 3 toobtain a p-hydroxy aldehyde compound 4; and the compound 4 and thiosemicarbazide are condensed to obtain a thiosemicarbazide Schiff base compound 5. The compound 5 can specifically recognize Hg and ClO, and the probe emits orange red fluorescence in the presence of Hg under the irradiation of 365nm ultraviolet light. In the presence of ClO, the probe emits green fluorescence, and inthe presence of other anions and metal ions, fluorescence does not occur. Therefore, the compound 5 can be used as a dual-channel fluorescent probe and has good application value.

Berberine (BBR) exhibits diverse bioactivities, including anticancer activity; but its poor druggability limits its applications. In this study, we designed and synthesized a series of 9-O position modified BBR derivatives aiming to improve its cell permeability and anticancer activity, utilizing a long alkyl chain branched by hydroxyl group and methoxycarbonyl group. Among these compounds, B10 showed 3.6-fold higher intracellular concentration than BBR, as well as 60-fold increased anti-proliferation activity against human lung cancer A549 cells compared with BBR. Treatment with B10 (1, 2 μM) induced apoptosis of A549 cells. Further investigations showed that B10 treatment dose-dependently affected mitochondrial functions, including oxygen consumption rate (OCR), mitochondrial membrane potential (MMP) and the morphology of mitochondria in A549 cells. Therefore, this work offers a new way for BBR structural modification through improving cell membrane permeability to affect mitochondrial functions and potential anti-tumor therapy in the future.
