Preparation of 4,7‐Dihalobenzo[b]Thiophene Derivatives Containing Iodine Atoms and Their Cross Coupling With Arylethynes

Journal of Heterocyclic Chemistry, Volume 63, Issue 6, Page 982-996, June 2026.
Quasi T‐shaped three‐way benzo[b]thiophene scaffolds, containing iodine atom(s) at the 4‐ and/or 7‐position, were prepared by several methods such as silica gel‐assisted cyclization. The iodobenzo[b]thiophenes thus prepared were subjected to Sonogashira cross couplings to give various ethynylbenzo[b]thiophenes.

Covalent drug rescue of multiple p53 mutants by stabilizing vinyl sulfone fragments hints to a specific refolding mechanism for R282W

Protein Science, Volume 35, Issue 6, June 2026.
Abstract The tumor suppressor protein p53 plays a crucial role in cell cycle regulation. In approximately 50% of all tumors, mutations in p53 are observed. Although the top hot spot mutations impair DNA binding, other mutations affect the thermal stability of the protein, leading to its rapid denaturation in physiological conditions.

Selective Fluorescent Probe Based on Thiomethyl‐Substituted Bis(arylidene)ketone for Hypochlorite Detection in Water Samples

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
The synthesized probe (SMAK) is the first bis(arylidene)ketone derivative for hypochlorite sensing. It was prepared in one step following two alternative routes; the traditional solution method and a greener solvent‐free method. Probe was found to have excellent selectivity over interfering anions, cations and oxidants and the mechanism of sensing and ...

Identification and Quantification of Volatile Organic Compounds and Bioaerosols in the Conservation Processes of Guanche Mummies

Archaeometry, Volume 68, Issue 3, Page 561-572, June 2026.
ABSTRACT The Guanche mummies, ancient inhabitants of the Canary Islands, represent a significant part of the historical heritage preserved at the Museum of Nature and Archaeology (MUNA) in Tenerife, Spain. These mummies, subjected to artificial conservation practices, are of great interest to conservators seeking to understand their mummification ...
