The Schiff base ligands and their complexes have significant importance in chemistry, ..

Because of the relative easiness of preparation, synthetic flexibility, and the special property of C=N group, Schiff bases are generally excellent chelating agents [2, 4, 5, 6] especially when a functional group like –OH or –SH is present close to the azomethine group so as to form a five or six membered ring with the metal ion.

Synthesis, antiviral activity and cytotoxicity investigation of Schiff bases of some 2-phenyl-3-substituted quinazoline-4(3)H-ones.

One representative group of macrocycles comprise Schiff base macrocyclic compounds, which are synthesized by the reaction of dicarbonyl compounds with diamines via a well-understood mechanism [, ].

We also noted that a representative Schiff base macrocycle, containing a 2, 6-diamidopyridine subunit, could have an important role to play in the molecular recognition of organic molecules and inorganic anions [-].

Synthesis, antiviral activity and cytotoxicity evaluation of Schiff bases of some 2-phenyl quinazoline-4(3)H-ones.

Schiffbase macrocycles 1 and 2 were synthesized by the Schiff base condensation of pyridine-2, 6-dicarboxamide with 1, 10-bis(2'-formylpheny-loxy)decane in the presence of phosphoric acid a one-pot process.

Experimental Synthesis of the Schiff-base macrocycle 1 and 2: Precursor pyridine-2, 6-dicarboxamide was prepared from the reaction of commercial pyridine-2, 6-dicarbonyl dichloride with 2-nitrobenzenamine according to a literature procedure for similar structures [].

In our previous work, we showed that a new category of macrocyclic Schiff bases can be synthesized employing a metal template procedure [, ].

The regioselective preparation of 2,5-disubstituted pyrroles, useful structural scaffolds, is important. To this end, a protocol based on a stepwise iododesilylation and a subsequent coupling reaction, involving a 6-step pathway starting from the simplest pyrrole, has been realised. This methodology can be widely used in the synthesis of drugs, molecular wires, and high-molecular-weight polymers.

All the chemicals used were of analytical grade and were used without further purification. CT-DNA and pUC19 plasmid DNA were purchased from Sigma. Elemental analyses (carbon, hydrogen, nitrogen, oxygen and sulphur) were performed using a Perkin-Elmer 240 elemental analyzer. IR spectra of the Schiff base ligands and their complexes were recorded on a Shimadzu FT-IR-8300 instrument using KBr discs in the range of 4000–200cm−1. 1H-NMR spectra of the synthesized compounds were recorded on Bruker DRX-300 spectrometer using DMSO-d6 as solvent and TMS as the internal standard. Molar conductivity measurements were recorded on a CM-82T Elico conductivity bridge in DMSO. Thermogravimetric analyses data were measured from room temperature to 700°C at a heating rate of 20°C/min. The data were recorded on a Shimadzu TG-50 thermobalance. Absorption spectra were recorded using a hp spectrophotometer (Agilent 8453).

However, in spite of such an importance the number of reports available on organotin(IV) complexes and their DNA binding properties is very few. As an extension of the studies of organotin(IV) complexes with Schiff bases [, ], we have now synthesized four organotin(IV) complexes with Schiff bases, 2-(2-hydroxybenzylideneamino)isoindoline-1,3-dione, and 4-(4-hydroxy-3-methoxybenzylideneamino-N-(pyrimidin-2-yl) benzenesulfonamide.
