Effective delivery and controlled release of metallo-prodrugs with sustained activation and rapid response feed the needs of precise medicine in metal chemotherapeutics. However, gold-based anticancer drugs often suffer from detoxification binding and extracellular transfer by sulfur-containing peptides. To address this challenge, we integrate a thiol-activated prodrug strategy of newly prepared hypercoordinated carbon-centered gold(I) clusters (HCGCs) with their photosensitization character to augment the mitochondrial release of Au(I) in tumors.

This study aims to reveal the potential molecular mechanisms of modified Gegen Qinlian decoction (MGQD) in relieving ulcerative colitis (UC). C57BL/6J mice were used to establish experimental colitis via dextran sodium sulfate (DSS). Body weight, disease activity index (DAI), spleen weight, colon length, and histopathologic features were measured to evaluate the therapeutic effects of MGQD on mice with UC.

Oxidative stress and inflammatory dysregulation play crucial roles in pathogenesis of acute lung injury (ALI), and their cyclic synergy drives excessive inflammatory responses and further exacerbates ALI. Therefore, new effective strategies to treat ALI are urgently needed. Herein, a novel synergistic selenium based chlorogenic acid nanoparticle was developed to disrupt the cyclic synergistic effect between oxidative stress and inflammatory response in ALI.

The necrosis of pancreatic acinar cells is a key molecular event in the progression of acute pancreatitis (AP), with disturbances in mitochondrial energy metabolism considered to be a direct causative factor of acinar cell necrosis. Histidine triad nucleotide-binding protein 2 (HINT2) has been implicated in the development of various diseases, whereas its involvement in the progression of AP remains unclear. This study aims to investigate the role of HINT2 in AP.
