Synthetic and Structural Studies of Lead(II) Complexes with Schiff Bases of Sulfa Drugs

Synthesis, spectroscopic characterization, and 3D molecular modeling of lead(II) complexes of unsymmetrical tetradentate Schiff-base ligands

“…This is further supported by the upward shift in the phenolic m(C-O) [32] to the extent of 25-40 cm -1 . On complexation, the m(C=N) band is shifted to lower wave number relative to the free ligand, indicating that the nitrogen of the azomethine group is coordinated to the metal ion, which may be attributed to lowering of the m(C=N) bond order as a result of Pb / N bond formation [33]. This is supported by upward shift in m(C-N) to the extent of 10-30 cm -1 .…”

Synthesis and characterization of Pb(II) complexes of Schiff bases derived from 3-methyl-4-fluoroacetophenone and amino acids

“…These results suggest that the azomethine nitrogen and carboxylate oxygen groups are involved in coordination with the lead(II) ion in the complexes. Several new bands appear in the complexes at *430 and *545 cm -1 , and are probably due to m(Pb-O) [30] and m(Pb/N) [30], respectively. their IR spectra.…”

Design, spectral, thermal decomposition, antimicrobial, docking simulation and DNA binding tendency of sulfisoxazole azo dye derivative and its metal chelates with Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+ and Cd2+

“…[1] They are used as anticancer drugs and antibacterial drugs and in the treatment of tuberculosis, malaria and diabetes, and sulfonamides are considered drugs of choice for the treatment of nocardiosis. [1][2][3][4] Sulfonamides and their derivatives act selectively and therefore can be used as preventive and curative agents for various diseases. [5] Recently, it is found that when some of these drugs are given in the form of metallic derivatives, they have a higher biological activity.…”
