Palladium(II) complexes of 2-benzoylpyridine-derived thiosemicarbazones: spectral characterization, structural studies and cytotoxic activity

“…The 2-benzoylpyridine-derived thiosemicarbazones were prepared as described in the literature [12,13]. The palladium complexes were obtained by mixing a methanol solution of the desired ligand with [PdCl 2 -(DMSO) 2 ] in 1:1 molar ratio at room temperature under stirring for 24 h. The solids were washed with ethanol followed by diethylether and then dried in vacuo.…”

“…doi:10.1016/j.jinorgbio.2004.11.022 pyridine have been extensively investigated by other authors [3][4][5][6] and by some of us [7][8][9][10][11]. For the 2-benzoylpyridine analogues, a few transition metal complexes have been reported in the literature and their activity against human pathogenic fungi was shown [12,13].…”

N(4)-tolyl-2-benzoylpyridine thiosemicarbazones and their copper(II) complexes with significant antifungal activity: crystal structure of N(4)-para-tolyl-2-benzoylpyridine thiosemicarbazone

“…The signal at δ = 13.03 ppm for HL3 and at δ =13.14 ppm for H2Bz4Ph 5 are characteristic of N(3)-H hydrogen bonded to the pyridine nitrogen in the Z configuration, whereas those at δ = 10.48 ppm for HL3 and at δ = 10.63 ppm for H2Bz4Ph 5 are characteristic of N(3)-H hydrogen bonded to DMSO (E configuration). 5,6,17 The Z form is predominant in solution (70%) for both compounds.…”

Tin(IV) complexes of 2‐benzoylpyridine N(4)‐phenyl‐thiosemicarbazone: spectral characterization, structural studies and antifungal activity

“…1,2 The pharmacological activities of α(N)-heterocyclic thiosemicarbazones derived from 2-formyl and 2-acetylpyridine have been extensively investigated, 3 -6 but much less attention has been given to the 2-benzoylpyridine analogues. For the latter, a few transition metal complexes have been prepared 7,8 and their activity against the human pathogenic fungi Aspergillus niger and Paecilomyces variotii has been demonstrated. 8 On the other hand, tin complexes are known for their biological interest as antitumorals, antibacterials, antifungals and biocides.…”
