Chiral discrimination asserted by enantiomers of Ni (II), Cu (II) and Zn (II) Schiff base complexes in DNA binding, antioxidant and antibacterial activities

A survey of consumer expectation in community pharmacies in Bandung, Indonesia

“…al., 2005. The spectra for the complex showed M-N bands at a lower wavelength in the range of 477-575 cm -1 (Raman, 2011 andKhan, 2011). The electronic spectra for the free ligands were obtained and showed absorption band in three distinct regions.…”

“…However, there were no significant differences between the metal(II) halides complexes as expected. The IR spectra of all the complexes possess very strong characteristic absorption bands in the region of 1670.00-1650.00cm -1 which is attributed to the C=N stretching vibration of the Schiff base imino functional group (Raman, 2011, Khan et. al., 2011, Nakamoto, 1978, Inamur et.…”

Synthesis, characterization, and biological applications of some 2-acetylpyridine and acetophenone derivatives

“…However, there were some significant differences between the metal (II) halides complexes and that of the azides and thiocyanate complexes, as expected. The IR spectra of all the complexes possess very strong characteristic absorption bands in the region of 1670.00-1650.00cm -1 which is attributed to the C=N stretching vibration of the Schiff base imino functional group (Gwaram et al, 2012;Khan et al, 2011;Nakamoto et al, 1978;Laskar et al, 2001 andBanerjee et al, 2005). For thiocyanates and azide complexes a chemical shifts were observed at a region of 2110-2020 attributable to metal coordination (Pallab et al, 2010).…”

Chiral superstructures from homochiral Zn2+, Co2+, Fe2+‐2,6‐bis (aryl ethylimine)pyridine complexes

“…In the design and the synthesis of chiral ligands that, upon coordination with metal ions, can induce high stereoselectivity at a supramolecular level, Schiff bases with stereogenic centres in their backbones have been extensively used as powerful tools for the spontaneous generation of chiral superstructures. Typically, these chiral Schiff bases are obtained by condensation between aldehydes and chiral primary amines, and, among the most frequently used chiral amines, one can include enantiomeric pairs of R‐(+)‐1‐/S‐(−)‐1‐phenylethylamine and R‐(+)‐1‐/S‐(−)‐1‐naphthylethylamine …”
