Synthesis of Heterocycles via Pd-Ligand Controlled Cyclization of 2-Chloro-N-(2-vinyl)aniline: Preparation of Carbazoles, Indoles, Dibenzazepines, and Acridines

open access: yes, 2016
The Pd-catalyzed condensation of 2-bromostyrene and 2-chloroaniline derivatives yields stable diphenylamine intermediates, which are selectively converted to five-, six-, or seven-membered heteroaromatics (indoles, carbazoles, acridines, and ...

Synergistic Effects of Thyroxine and Nano‐Melatonin on Post‐Thaw Sperm Quality, Antioxidant Defence and Fertility of Cryopreserved Simmental Bull Semen

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Effects of thyroxine (T) and nano‐melatonin (NM) supplementation on cryopreserved Simmental bull semen were evaluated. The combination of thyroxine (0.5 µg/dL) and nano‐melatonin (30 µg/dL) significantly improved post‐thaw sperm motility, membrane integrity, antioxidant status, and fertility while reducing oxidative stress and apoptosis. These findings

Hypercapnia Induces Mitochondrial Adaptations and Alters Glutamine Metabolism to Drive a Distinct Metabolic Phenotype in Monocytes

open access: yesImmunology &Cell Biology, Volume 104, Issue 10, Page 943-963, November‐December 2026.
Elevated CO2 (hypercapnia) is a feature of serious lung diseases, for example COPD and contributes to poor patient prognosis through modulation of immune cell function. Here we employ state‐of‐the art metabolomic and isotope tracing approaches to reveal CO2‐dependent mitochondrial alterations linked to suppressed ATP, proline and glutamate levels in ...
