In a paper published in Mycology, an international team of scientists mainly reported the isolation and characterization of two new pairs of (±)-penithrones A (1) and B (2), and a chlorinated derivative (±)-penithrone C (3), along with their biogenetic precursors (4–6), from the mangrove-derived fungus Penicillium hispanicum LA032. The study demonstrated significant cytotoxic activity of compounds 1 and 2 against multiple cancer cell lines (IC50 = 5.09–9.47 μmol/L), and identified MAPK10 as a potential molecular target through integrated network pharmacology and molecular docking approaches, providing new insights into fungal-derived anticancer agents.

Acta Pharmaceutica Sinica B (APSB) was founded with the goal of creating a global high-level forum centred around drug discovery and pharmaceutical research/application. APSB was included by Chemical Abstracts in 2011, accepted by PubMed Central in 2015, indexed by Science Citation Index in 2017 and has evolved to become one of the most important international journals in the field of pharmaceutical sciences.
A new study led by investigators from Mass General Brigham trialed stereotactic (targeted) brain-directed radiation in 100 patients with small cell lung cancer and brain metastases, finding they experienced positive outcomes that support use of targeted radiation in the future for such patients. Results are published in the Journal of Clinical Oncology.
In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this oversimplification undersells the significance of the genome’s 3D structure. Problems with this 3D structure are associated with many diseases including developmental disorders and cancer.
Scientists at Sanford Burnham Prebys and colleagues in Hong Kong published findings June 27, 2025, in Genome Biology demonstrating a new approach for better understanding the human genome’s 3D structure and its influence.Single-atom nanozymes (SAzymes) hold significant potential for tumor catalytic therapy, but their effectiveness is often compromised by low catalytic efficiency within tumor microenvironment. This efficiency is mainly influenced by key factors including hydrogen peroxide (H2O2) availability, acidity, and temperature. Simultaneous optimization of these key factors presents a significant challenge for tumor catalytic therapy. In this study, we developed a comprehensive strategy to refine single-atom catalytic kinetics for enhancing tumor catalytic therapy through dual-enzyme-driven cascade reactions. Iridium (Ir) SAzymes with high catalytic activity and natural enzyme glucose oxidase (GOx) were utilized to construct the cascade reaction system. GOx was loaded by Ir SAzymes due to its large surface area. Then, the dual-enzyme-driven cascade reaction system was modified by cancer cell membranes for improving biocompatibility and achieving tumor homologous targeting ability. GOx catalysis reaction could produce abundant H2O2 and lower the local pH, thereby optimizing key reaction-limiting factors. Additionally, upon laser irradiation, Ir SAzymes could raise local temperature, further enhancing the catalytic efficiency of dual-enzyme system. This comprehensive optimization maximized the performance of Ir SAzymes, significantly improving the efficiency of catalytic therapy. Our findings present a strategy of refining single-atom catalytic kinetics for tumor homologous-targeted catalytic therapy.
A clinical trial has shown that a new chemotherapy for Hodgkin’s lymphoma has fewer harmful effects on patients’ later fertility than the previous treatment / Publication in “The Lancet Oncology”
Four years after pre-surgery treatment with a novel combination of immune checkpoint inhibitors, nivolumab and relatlimab, 87% of patients with stage III melanoma remained alive, according to new results from a study led by researchers at The University of Texas MD Anderson Cancer Center.
A breast scan for detecting cancer takes less than a minute using an experimental system that combines photoacoustic and ultrasound imaging, according to a study in IEEE Transactions on Medical Imaging. The system does not require painful compression like mammography. In tests, it produced clear, artificial intelligence-powered 3D images of common breast cancer subtypes such as Luminal A, Luminal B and Triple-Negative Breast Cancer.
