Synthesis, Structure, and Antiproliferative Activity of trans-Palladium(II) Complexes with Tetrazol-2-ylacetic Acid Derivatives

A series of trans-palladium(II) complexes (trans-[PdCl2L2], L = ethyl 5-R-2H-tetrazol-2-ylacetate, 5-R-2H-tetrazol-2-ylacetamides, R = Me, Ph) has been synthesized, and their structure has been proved by 1H and 13C–{1H} NMR and high-resolution mass spectra and X-ray analysis. Antiproliferative activity of the synthesized complexes has been determined, and the mechanism of their interaction with DNA has been studied by UV and CD spectroscopy.
