DOI: 10.1016/j.tet.2016.12.011
Abstract: Abstract Two quinazolinone-based Schiff's bases ( 1 and 2 ) have been studied by UV/vis, EPR, and NMR spectroscopic methods, as well as DFT calculations. UV/vis spectroscopy confirmed that both compounds undergo significant changes upon… read more here.

DOI: 10.1039/c9ra10730d
Abstract: EPR and NMR experiments on a quinazolinone-based Schiff's base in DMSO solution showed that irradiation with UV light (365 nm) leads to photochemically-induced isomerization from the anti- to the higher-energy syn-form around the –N–N linkage.… read more here.

DOI: 10.3390/ijms23126554
Abstract: Multiple-system trophy (MSA) and Parkinson’s Disease (PD) are both progressive, neurodegenerative diseases characterized by neuropathological deposition of aggregated alpha-synuclein (αSyn). The causes behind this aggregation are still unknown. We have reported aberrancies in MSA and… read more here.
