Japanese plants produce compounds that exhibit potent anti-HIV activity
Structure of previously undescribed daphnene diterpenoids isolated from D. pseudomezereum.. Credit: Dr. Wei Li Researchers have discovered that Daphne Pseudomezereum (commonly known as Onishibari) contains substances that inhibit human immunodeficiency virus (HIV) replication. The plants were grown in the Medicinal Plant Gardens of the Faculty of Pharmaceutical Sciences at Tohhon University. This finding is expected to lead to the discovery…

Unfamiliar faces of the most unfamiliar substances: extraordinary activity of interfacial water on oil droplets
Raman-MCR spectroscopy of oil droplets in water. Credit: Nature (2025). doi:10.1038/s41586-025-08702-y Water behavior at hydrophobic interfaces has been baffling scientists for over a century, ranging from chemistry, biology, materials science, geology, and engineering. Recent discoveries highlight the pivotal role of interfacial water, including the unusual chemistry of water microdopplets and contact with electrocatalytics. A new study published in Nature systematically…

Nanocylbar complexes derived from green tea indicate anti -black acoustic activity.
Credit: nadezhda Ivanova Blackoma is a rapidly progressing skin that features high mortality after transition. Local chemotherapy can be regarded as a treatment approach only during surgical removal (in Situ melanoma) and postoperative stages while suspected of skin lesions. For this purpose, drugs such as Imikimodo, 5-fluorouracil, Dakarbazine, and Doxorbicin have been tested, indicating positive effects. Recently, the metal nanoparticle…

Study reveals that cobalt ions, rather than the covalent organic skeleton itself, promote catalytic activity
a) Schematic diagram of the synthesis of TpBpy-Co COF. b) PXRD patterns of TpBpy and TpBpy-Co (Cu Kα1). c) N2 adsorption (filled) and desorption (empty) isotherm profiles at 77 K. Credit: Advanced Science (2024). DOI: 10.1002/advs.202413555 Covalent organic frameworks (COFs) are less stable catalysts than previously thought, but they maintain high activity. COFs are promising designer catalysts, including in the…
