Schiff base denotes a reaction product of a primary amine and a carbonyl compound. Schiff bases possess a wide variety of biological activity specially antibacterial and antifungal properties. Metal complexes of Schiff base have been studied for their biological activities. This review articles provide a summary of medicinal chemistry features of Schiff base and various reports published on bio...

Brightly NIR emissive ytterbium Schiff base complex was predicted by NMR spectroscopy and used for bioimaging. Its structure in solution determined spectroscopy.

A metal template approach affords in high yield a tetra-Zn(salphen) macrocycle (3) which shows strong and cooperative self-assembly mediated by the formation of Zn(salphen) dimer units held together via μ(2)-phenoxo interactions. A cooperative binding mode for the tetranuclear Zn(4) macrocycle 3 is supported by comparison of UV-vis and fluorescence titration data recorded for 3 when compared wi...

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

Schiff base ligand (E)-4-[(hydroxyl phenylimino)methyl]benzene-1, 2-diol (H3L) was prepared from the condensation reaction of Protochatechu aldehyde (3, 4-dihydroxybenzaldhyde) with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides and Fe(III) and Zn(II) nitrates in 2M:1L molar ratio, the five new neutral complexes were prepared. The character...

Expansion of a Schiff-base polypyrrolic macrocycle allows the formation of a binuclear uranyl complex with co-linear uranyl ions and a very short oxo-oxo distance.

A ladder-like coordination polymer involving a dinuclear Zn Schiff-base complex possesses organic linkers that undergo [2+2] photodimerisation in the solid state.

A new Sulfamethoxazole Schiff base (E)-4-(4-methoxybenzylideneamino)-N(5-methylis-oxazol-3-yl) benzenesulfonamide (C18H17N3O4S), and its copper complex were synthesized and the structures elucidated on the basis of Physiochemical methods. The studies indicate an octahedral structure for the complexes with the (C22H27N3O10SCu) formula. The IR spectra suggest that the ligand act as tridentate (fr...

A new class of rhodopsins covalently linked to an enzymatic domain was discovered recently. A member of this class of enzymerhodopsins, the rhodopsin-guanylyl cyclase (RhGC) was identified in the aquatic fungus Blastocladiella emersonii (BE). Characterization of RhGC showed that the second-messenger molecule cGMP (cyclic guanylyl monophosphate) is produced upon green light illumination. Here, t...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...
