Ray, Synthesis and metal ion uptake studies of chelating resins derived from formaldehyde-furfur aldehyde condensed phenolic Schiff bases
of 4, 4'-diaminodiphenylether and o-hydroxyacetophenone, Talanta, 57, 1075 (2002).
The NMR spectra of Schiff bases
were recorded in dimethylsulfoxide (DMSO) solution, using tetramethylsilane (TMS) as standard.
In recent years, several Schiff base
metal complexes have been widely used in diagnostics and medicine [1-4].
Other amino-acids containing primary amino group also react with FAA to form Schiff bases
and elute from GC column.
Various studies have shown that amino acid metal complexes of Schiff bases
have antibacterial (Venkatesh, 2011; Mounika et al., 2010), anticancer (Miri et al., 2013; Ali et al., 2012) and antioxidant (Wei et al., 2000) activities.
Comparable cytotoxicity was noted only for the precursors (anthracene-based Schiff bases
S-1 and S-2) with the highest sensitivity of the ALL (REH) cells.

Indeed, Schiff base
compounds and their metal complexes are outstanding in the domain of metal-based drugs.
The level of primary products naturally decreases, while the level of triene conjugates and Schiff bases
increases uniformly when passing from [N.sub.0][M.sub.0] to [N.sub.3][M.sub.0].

There are evidences confirming that salicylaldehyde Schiff bases
, obtained from the condensation of the salicylaldehyde and its derivatives in alkaline grind solution [8, 9], showed abetter carrying oxygen ability and catalysis of mimic enzymes due to their structure similar to the porphyrin and phthalocyanine rings, which displayed a great anticancer, anti-inflammatory, antibacterial, and antiviral activity.
