2-Methylsulfanylbenzo[f]isoquinoline [PDF]
, 2015 S-Methylation of a 4-(naphth-2-yl)-β-thiolactam gives an intermediate 4-(naphth-2-yl) substituted 1-azetine which undergoes a [2+2] ring-opening followed by electrocyclic ring closure of the resulting 2-azadiene to give a benzo[f ...

Drug Development Research, Volume 86, Issue 3, May 2025.ABSTRACT Caffeic acid phenethyl ester (1), a honeybee propolis component, possesses many bioactive properties, making it a useful scaffold for drug research. Further, CAPE (1) is a more effective inhibitor of the biosynthesis of 5‐lipoxygenase (5‐LO) products compared to Zileuton, the only clinically‐approved direct 5‐LO inhibitor.

Thermally Stimulated Luminescence and Current in new heterocyclic materials for Organic field transistors and organic light emitting diodes [PDF]
arXiv, 2007 The present work is focused on theoretical and experimental study of localised levels in organic materials suitable for light-emitting devices and field effect transistors by means of thermal techniques. In our work we focused on low molecular compounds as well as on polymers, especially of two classes of materials: oxadiazoles and quinoxalines.

IUBMB Life, Volume 77, Issue 5, May 2025.ABSTRACT Tumor suppressor genes are frequently targeted by mutations introducing premature termination codons (PTC) in the protein coding sequence, both in sporadic cancers and in the germline of patients with cancer predisposition syndromes. These mutations have a high pathogenic impact since they generate C‐terminal truncated proteins with altered ...
