Resumen
The palladium(II) bis-chelate complexes of the type [Pd(TSC1−5)2] (6–10), with their corresponding ligands 4-phenyl-1-(acetone)-
thiosemicarbazone, HTSC1 (1), 4-phenyl-1-(2-chloro-benzaldehyde)-thiosemicarbazone, HTSC2 (2), 4-phenyl-1-(3-hydroxybenzaldehyde)-
thiosemicarbazone, HTSC3 (3), 4-phenyl-1-(2-naphthaldehyde)-thiosemicarbazone, HTSC4 (4), and 4-phenyl-
1-(1-nitro-2-naphthaldehyde)-thiosemicarbazone, HTSC5 (5), were synthesized and characterized by elemental analysis and
spectroscopic techniques (IR and 1H- and 13C-NMR). The molecular structure of HTSC3, HTSC4, and [Pd(TSC1)2] (6) have been
determined by single crystal X-ray crystallography. Complex 6 shows a square planar geometry with two deprotonated ligands
coordinated to PdII through the azomethine nitrogen and thione sulfur atoms in a cis arrangement. The in vitro cytotoxic activity
measurements indicate that the palladium(II) complexes (IC50 = 0.01–9.87 𝜇M) exhibited higher antiproliferative activity than
their free ligands (IC50 = 23.48–70.86 and >250 𝜇M) against different types of human tumor cell lines. Among all the studied
palladium(II) complexes, the [Pd(TSC3)2] (8) complex exhibited high antitumor activity on the DU145 prostate carcinoma and
K562 chronic myelogenous leukemia cells, with low values of the inhibitory concentration (0.01 and 0.02 𝜇M, resp.).
