Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Small Band Gap Polymers Synthesized via a Modified Nitration of 4,7-Dibromo-2,1,3-benzothiadiazole [PDF]

, 2010
The nitration of 4,7-dibromo-2,1,3-benzothiadiazole was modified by using CF3SO3H and HNO3 as the nitrating agent, and the related yield was improved greatly.

Evidence that 5‐HT2A receptor signalling efficacy and not biased agonism differentiates serotonergic psychedelic from non‐psychedelic drugs

British Journal of Pharmacology, EarlyView.
Background and Purpose Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5‐HT2A receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5‐HT2A receptor ligand bias or signalling efficacy. Here,

A Curcumin‐Derived HSP70 Inhibitor Disrupts Lysosomal Function to Suppress Triple‐Negative Breast Cancer Progression

Cell Proliferation, EarlyView.
Novel curcumin‐derived M4 binds HSP70's ATPase domain, disrupting HSP70‐mediated lysosomes‐autophagy pathway to inhibit TNBC growth and metastasis, and synergizes with paclitaxel for potent combination therapy. ABSTRACT Structural modification of curcumin yielded a novel series of 1,4‐pentadien‐3‐one oxime ether derivatives, among which compound M4 ...

A Comparative Analysis of Maillard‐Derived α‐Dicarbonyl Compounds and Advanced Glycation End Products in Fresh, Wet, Kibble, and Freeze‐Dried Dog Foods

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Thermal processing of pet foods can lead to the formation of harmful Maillard reaction products (MRPs), which may compromise nutritional quality and pose health risks to companion animals. This study compared the levels of MRPs in 41 commercial dog foods, including fresh (n = 15), kibble (n = 13), wet (n = 10), freeze‐dried (n = 2), and cold ...
