Efficient synthesis and anti-bovine viral diarrhea virus evaluation of 5-(aryldiazo)salicylaldehyde thiosemicarbazone derivatives

An efficient procedure for the synthesis of 5-(aryldiazo)salicylaldehyde thiosemicarbazone derivatives 1-25 was achieved via the condensation of 5-(aryldiazo)salicylaldehyde derivatives I–V with N-(4)-substituted thiosemicarbazide derivatives. Antiviral a

Synthesis, Characterization, Antibacterial, and Antifungal Activity of Novel 2-(2-hydroxy-5-((aryl)-diazenyl)phenyl)-3-(4-hydroxyphenyl)-thiazolidin-4-one

A series of novel thiazolidinones, that is, 2-(2-hydroxy-5-((aryl)-diazenyl)phenyl)-3-(4-hydroxyphenyl)-thiazolidin-4-one, have been synthesized by reaction of various Schiff bases 2-(4-hydroxyphenylimino)methyl)-4-(aryl)diazenyl)phenol with ethanolic thioglycolic acid. Schiff bases were obtained by the reactions of 4-amino phenol with 2-hydroxy-5-((aryl)diazenyl)benzaldehyde. The structures of the newly synthesized compounds were confirmed by IR,1H NMR, mass spectra, and C, H, N elemental analysis. The thiazolidinone derivatives were evaluated for their antibacterial and antifungal activity.

Facile and Mild Synthesis and Characterization of Some New Diazo Dyes on the Basis of Schiff Bases in the Presence of Nanocrystalline Magnesium Oxide as a Base Catalyst under Solvent-free Conditions

In this research, some new diazo dyes including Schiff base have been synthesized by the condensation reaction between ethylenediamine and derivatives of salicylaldehyde containing diazo functional groups in the presence of nanocrystalline magnesium oxide

Synthesis and biological activity evaluation of some binuclear metal complexes of Cu(II) and Zn(II) with tridentate schiff base ligands

A few kinds of new Schiff bases were synthesized by reaction of 2-aminophenol and corresponding synthesized azo compounds 3a-e. Further reaction of these Schiff bases 4a-e with transition metal salts as Cu(II) and Zn(II) gave corresponding binuclear complexes 5a-e and 6a-e. The antibacterial activity of prepared complexes was investigated against Staphylococcus aureus and Escherichia coli bacteria. The results for some compounds revealed a moderate to good inhibition against Staphylococcus aureus compared with penicillin zone of inhibition.

New 1,2,4-triazole-based azo-azomethine dyes. Part II: Synthesis, characterization, electrochemical properties and computational studies

A new series of monoiminated 1,2,4-triazole-based azo-azomethine dyes have been synthesized via condensation reaction of 4-amino-3-methyl-5-mercapto-1,2,4- triazole with various substituted azo-coupled salicylaldehyde. The dyes have been characterized by using FT-IR, UV-Vis and 1H NMR spectroscopic methods as well as elemental analysis. The electrochemical behavior of the dyes has been investigated by cyclic voltammetry in DMSO at five different scan rates. Solvatochromic behavior of the dyes has been also investigated in four organic solvents with different polarities. Furthermore, the 1H chemical shielding of the dyes were studied by the gauge independent atomic orbital (GIAO) method at the level of density functional theory (DFT).
