Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

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

Journal of Heterocyclic Chemistry, EarlyView.
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.

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).
