“…Interestingly, Schiff base-Fe 2+ complexes have been incorporated into nanomicelles PAsc/Fe@Cy7QB, which represent chemodynamic theranostics able to specifically recognize and eradicate cancer cells in solid tumors [32]. Transition metal complexes with Schiff bases are also used as electrode modifiers in sensors to detect analytes of pharmaceutical, environmental and forensic interest, mainly to analyze illicit drugs [33]. Recently, the development of a coumarin Schiff base system has been described as a highly selective fluorescent/colorimetric probe for Cu 2+ and as a tumor biomarker for glutathione detection [34].…”

Metal complexes play an essential role in pharmaceutical sciences for their multiple and important activities. Schiff bases are versatile pharmacophores able to form chelating complexes with several metals in different oxidation states. Complexes with Schiff bases are widely described in the literature for their multiple actions and numerous advantages, such as low cost and easy synthesis. They show multiple biological activities, including antimicrobial, antioxidant, antimalarial, antinflammatory and antitumor. Schiff bases may also form complexes with lanthanides and actinides acting as catalysts (e.g., in various synthetic processes) and antitumor agents. This review intends to extend on our previous paper regarding Schiff bases as antitumorals, highlighting the importance, in the field of the anticancer agents, of these tools as ligands of metal complexes.

Main‐group‐metal‐mediated transformations of imines have earned a valued place in the synthetic chemist's toolbox. Their versatility allows the simple preparation of various nitrogen containing compounds. This review will outline the early discoveries including metallation, addition/cyclisation and metathesis pathways, followed by the modern‐day use of imines in synthetic methodology. Recent advances in imine C−F activation protocols are discussed, alongside revisiting “classic” imine reactivity from a sustainable perspective. Developments in catalytic methods for hydroelementation of imines have been reviewed, highlighting the importance of s‐block metals in the catalytic arena. Whilst stoichiometric transformations in alternative reaction media such as deep eutectic solvents or water have been summarised. The incorporation of imines into flow chemistry has received recent attention and is summarised within.

“…The development of chemically modified carbon paste electrodes has attracted researchers' interest in recent years 30 . These sensors are low-priced and easy to manufacture, by mixing the conductive material, such as graphite powder or carbon nanotube, with an agglutinate, such as mineral oil or paraffin, and various types of modifiers such as transition metal complexes containing Schiff bases can be used [30][31][32][33] . Salen-type ligands (Salen = N,N-ethylene-bis(salicylideneiminato) have been applied in many electrochemical sensors because they display versatile stereo and electronic properties 30 .…”

In recent years, practical, inexpensive, and highly specific electroanalytical methods based on modified electrodes have been increasingly developed for forensic science. Simple modification of the carbon paste electrode with Schiff base complexes has become a promising strategy to detect and quantify narcotics. In this context, we aimed to develop voltammetric methods to quantify lysergic acid diethylamide (LSD) by using a carbon paste electrode modified with the complex [UO2(Ac-ophen)]·H2O. The use of an aqueous solution of KCl as supporting electrolyte makes the methodology less polluting, which contrasts with methods that still employ toxic solvents. The developed method for Differential Pulse Voltammetry provides a linear response at various concentrations of LSD and affords analytical curves with standard deviation, detection, and quantification limits around 2.45, 0.625, and 2.08 μmol L-1, respectively. The recovery values of 103 and 108% prove that the developed method is suitable for application in forensic science.
