Integrated In Silico, In Vivo, and Deep Learning Approaches in the Discovery of Novel Candidate Molecules for Aedes aegypti Control

open access: yesArchives of Insect Biochemistry and Physiology, Volume 121, Issue 2, February 2026.
An integrated computational/experimental workflow was used to identify new candidate molecules for Aedes aegypti control. Docking of 1,070 chalcones against mJHBP, followed by in vivo assays, identified 4′‐chloro‐4‐methoxychalcone (2c) as the most active larvicide candidate.

Quinazoline, Pyrazolo[1,5-c]Quinazoline and Spiro Quinazoline Dimers from the Reaction of 2-Aminoacetophenone Hydrazones with Triphosgene

open access: yesJournal of Chemical Research, 2002
The reaction of hydrazones of 2-aminoacetophenone with triphosgene in dichloromethane or benzene in the presence of triethylamine gave quinazolines, pyrazolo[1,5-c]quinazoline and spiro quinazoline dimers. The latter compounds are being reported for the first time.

Nitrate Enhances Gastric Mucosa Defense and Repair Process in Ethanol‐Induced Gastric Ulcer Rats via the Notch–Tff2 Pathway

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Nitrate protects the three major barriers of the gastric mucosa, alleviating bleeding and inflammation of ethanol‐induced gastric ulcer in rats, and promotes migration of gastric epithelial cells, accelerating the restoration of the ulcerated epithelium, which is strongly related to TFF2, a gastric mucosal protective factor negatively regulated by the ...

Design, Synthesis, and Evaluation of Naphthyl Pyrazino‐Pyrido‐Pyrimidinones Targeting the Phosphoinositide 3‐Kinase/Alpha‐Serine/Protein Kinase B/Mammalian Target of Rapamycin Pathway

open access: yesChemistryOpen, Volume 15, Issue 2, February 2026.
Rationally designed naphthyl pyrazino‐pyrido‐pyrimidinones 3 and 4 inhibited 85%–94% of cancer cell growth. Compound 4 exhibited IC50 = 7.8–12.8 µM with tumor selectivity. Both induced G1 arrest and modulated ULK1, STAT3, alpha‐serine/protein kinase B (AKT), and autophagy via phosphoinositide 3‐kinase/mammalian target of rapamycin (PI3K/mTOR ...

Effect of Unique NNS Ligand in Manganese‐Catalyzed Transfer Hydrogenation Reaction—A DFT Mechanistic Study

open access: yesChemCatChem, Volume 18, Issue 2, 28 January 2026.
The mechanism of transfer hydrogenation between isopropanol and acetophenone based on NN‐Mn(CO)3 and NNS‐Mn(CO)2 complexes has been computed. Both complexes have similar activity under mild conditions. Isopropanol dehydrogenation represents the rate‐determining step. Transfer hydrogenation has a much lower barrier than hydrogenation using molecular H2.
