A machine learning framework can distinguish molecules made by biological processes from those formed through non-biological processes and could be used to analyze samples returned by current and ...

Naloxone, also known by the brand name Narcan, is one of the most important drugs in the United States' fight against the opioid crisis. It reverses an opioid overdose nearly instantly, restarting ...

Although this compound is a polycyclic aromatic hydrocarbon, severe intramolecular steric interactions force the anthracene nucleus to be greatly distorted from planarity, with an end-to-end twist of ...

Complex polycylic structures are found in nearly every biosynthetic class of natural products. In particular, an amazing range of rigid densely functionalized polycylic compounds are formed from ...

Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas ...

Spiroaspertrione A is a complex polycyclic compound naturally produced by the fungus Aspergillus sp. TJ23. First isolated in 2017, it quickly drew scientific attention for its promising ability to ...

Organic chemistry features a wide array of reactions for creating complex molecules, among which the Diels–Alder reaction stands out for its versatility and precision. This reaction enables the ...

The synthesis and isolation of a nitrogen-embedded polycyclic compound with strong antiaromaticity and stability was achieved for the first time by a research group at Ehime University. This result ...

University of Utah researchers at the Pulst-Scoles Laboratory have discovered that reducing levels of the STAUFEN-1 protein can prevent neuron death caused by DNA damage and p53 activation in ...
