Published: March 21, 2024

There is an urgent requirement to acquire a comprehensive comprehension of novel therapeutic targets for prostate cancer facilitate the development medications with innovative mechanisms. In this study, we identified gambogic acid (GBA) as specific pyroptosis inducer in prostatic cells. By using thermal proteome profiling (TPP) strategy, revealed that GBA induces by directly targeting canopy FGF signaling regulator (CNPY3), which was previously considered "undruggable". Moreover, through utilization APEX2-based proximity labeling method, found recruited delactatease SIRT1, resulting elimination lysine lactylation (Kla) on CNPY3. Of note, SIRT1-mediated delactylation influenced cellular localization CNPY3 promote lysosome rupture triggering pyroptosis. Taken together, our study distinctive target induction and its potential application therapy.

Novel Pt(IV) complex OAP2 induces STING activation and pyroptosis via mitochondrial membrane remodeling for synergistic chemo-immunotherapy

Acta Pharmaceutica Sinica B, Journal Year: 2023, Volume and Issue: 14(4), P. 1742 - 1758

Published: Dec. 16, 2023

Mitochondrial membrane remodeling can trigger the release of mitochondrial DNA (mtDNA), leading to activation cellular oxidative stress and immune responses. While role in promoting inflammation hepatocytes is well-established, its effects on tumors have remained unclear. In this study, we designed a novel Pt(IV) complex, OAP2, which composed oxaliplatin (Oxa) acetaminophen (APAP), enhance anti-tumor amplify response. Our findings demonstrate that OAP2 induces nuclear damage, resulting production DNA. Additionally, downregulates expression Sam50, promote mtDNA secretion, double-stranded accumulation ultimately synergistically activating intracellular cGAS-STING pathway. The induced by overcomes limitations Oxa STING pathway simultaneously promotes gasdermin-D-mediated cell pyroptosis. also dendritic maturation enhances quantity efficacy cytotoxic T cells, thereby inhibiting cancer proliferation metastasis. Briefly, our study introduces first small-molecule inhibitor regulates for active immunotherapy research, may provide creative idea targeting organelle therapy.

Developing a Hetero-Trinuclear Erbium(III)–Copper(II) Complex Based on Apoferritin: Targeted Photoacoustic Imaging and Multimodality Therapy of Tumor

Journal of Medicinal Chemistry, Journal Year: 2023, Volume and Issue: 66(22), P. 15424 - 15436

Published: Nov. 13, 2023

For the integration of targeted diagnosis and treatment tumor, we innovatively designed synthesized a single-molecule hetero-multinuclear Er(III)–Cu(II) complex (ErCu2) then constructed an ErCu2@apoferritin (AFt) nanoparticle (NP) delivery system. ErCu2 ErCu2@AFt NPs not only provided evident photoacoustic imaging (PAI) signal tumor but also effectively inhibited growth by integrating photothermal therapy, chemotherapy, immunotherapy. improved targeting ability decreased systemic toxicity in vivo. Furthermore, confirmed that inducing apoptosis autophagy cells activating immune The study provides novel strategy to develop therapeutic metal agents reveals their potential for accurate multimodality therapy cancer.

Improvement of the Antioxidant and Antitumor Activities of Benzimidazole-Chitosan Quaternary Ammonium Salt on Drug Delivery Nanogels

Marine Drugs, Journal Year: 2024, Volume and Issue: 22(1), P. 40 - 40

Published: Jan. 11, 2024

The present study focused on the design and preparation of acid-responsive benzimidazole-chitosan quaternary ammonium salt (BIMIXHAC) nanogels for a controlled, slow-release Doxorubicin HCl (DOX.HCl). BIMIXHAC was crosslinked with sodium tripolyphosphate (TPP) using ion crosslinking method. method resulted in low polydispersity index, small particle size, positive zeta potential values, indicating good stability nanogels. Compared to hydroxypropyl trimethyl chloride chitosan-Doxorubicin HCl-sodium (HACC-D-TPP) nanogel, salt-Doxorubicin (BIMIXHAC-D-TPP) nanogel show higher drug encapsulation efficiency loading capacity (BIMIXHAC-D-TPP 93.17 ± 0.27% 31.17 0.09%), release profiles accelerated vitro. chitosan-sodium (HACC-TPP), salt-sodium (BIMIXHAC-TPP) demonstrated favorable antioxidant capability. assay cell viability, measured by MTT assay, revealed that led significant reduction viability two cancer cells: human lung adenocarcinoma epithelial line (A549) breast (MCF-7). Furthermore, BIMIXHAC-D-TPP 2.96 times less toxic than DOX.HCl mouse fibroblast (L929). It indicated BIMIXHAC-based enhanced antitumor activities acidic-responsive could serve as nanocarrier.
