Development of titanium oxide-bound-α-aminophosphonate nanocomposite for adsorptive removal of lead and copper from aqueous solution

Water Resources and Industry, 2020
A novel nanocomposite (N–TiO2-α-Am.Ph) was designed by surface functionalization of nano titanium oxide (N–TiO2) with α-aminophosphonates (α-Am.Ph). A study was aimed to explore and investigate the uptake properties of (N–TiO2-α-Am.Ph) for divalent Pb/Cu

First Phosphonic‐Type Inhibitors and Activity‐Based Probes Specific to the O'nyong‐nyong Virus Capsid Protease

ChemMedChem, Volume 20, Issue 12, June 17, 2025.
The serine capsid protease (CP) catalyzes a crucial process of the alphaviral replication cycle; therefore, it constitutes an interesting therapy target. Herein, the O'nyong‐nyong virus CP profile activity with a specific fluorogenic substrate is analyzed and examines the inhibitory activity of a new series of phosphonic analogs of tryptophan and ...

On the Synthesis of [1,3]Azaphospholo[4,5‐f]quino(xa)lines and 2,3‐Dihydro‐[1,3]azaphospholo[4,5‐f]quino(xa)line 1‐oxides

European Journal of Organic Chemistry, Volume 28, Issue 17, May 21, 2025.
Syntheses of quinoline and quinoxaline derivatives fused with phosphacycles were developed from commercially available quinolin‐6‐amine and quinoxalin‐6‐amine. Abstract Despite their potential in areas such as medicinal chemistry and organic materials, scaffolds in which quinoline and quinoxaline are fused to phosphacycles such as 1,3‐oxaphosphole, 1,3‐
