- N6-benzyladenosine derivatives as novel n-donor ligands of platinum(ii) dichlorido complexes
-
The platinum(II) complexes trans-[PtCl2(Ln)2]·xSolv 1-13 (Solv = H2O or CH3OH), involving N6-benzyladenosine-based N-donor ligands, were synthesized; Ln stands for N6-(2-methoxybenzyl)adenosine (L1, involved in complex 1), N6-(4-methoxybenzyl) adenosine (L2, 2), N6-(2-chlorobenzyl)adenosine (L3, 3), N6-(4-chlorobenzyl)- adenosine (L4, 4), N6-(2-hydroxybenzyl)adenosine (L5, 5), N6-(3-hydroxybenzyl)- adenosine (L6, 6), N6-(2-hydroxy-3-methoxybenzyl) adenosine (L7, 7), N6-(4-fluorobenzyl) adenosine (L8, 8), N6-(4-methylbenzyl) adenosine (L9, 9), 2-chloro-N6-(3-hydroxybenzyl) adenosine (L10, 10), 2-chloro-N6-(4-hydroxybenzyl)adenosine (L11, 11), 2-chloro- N6-(2-hydroxy-3- methoxybenzyl)adenosine (L12, 12) and 2-chloro-N6-(2-hydroxy-5- methylbenzyl)adenosine (L13, 13). The compounds were characterized by elemental analysis, mass spectrometry, IR and multinuclear (1H-, 13C-, 195Pt- and 15N-) and two-dimensional NMR spectroscopy, which proved the N7-coordination mode of the appropriate N6-benzyladenosine derivative and trans-geometry of the title complexes. The complexes 1-13 were found to be non-toxic in vitro against two selected human cancer cell lines (HOS and MCF7; with IC50 > 50.0 μM). However, they were found (by ESI-MS study) to be able to interact with the physiological levels of the sulfur-containing biogenic biomolecule L-methionine by a relatively simple 1:1 exchange mechanism (one Ln molecule was replaced by one L-methionine molecule), thus forming a mixed-nitrogen/sulfur-ligand dichlorido-platinum(II) coordination species.
