Author is Moggi, Luca; Varani, Graziano; Sabbatini, Nanda; Balzani, Vincenzo.

The photochem. behavior of cis- and trans-Pt(py)2Cl2 in CHCl3 solutions has been investigated using 313 nm light. The cis isomer undergoes 2 simultaneous photoreactions, one being an intramol. photoisomerization process (Φisom ∼0.04) and the other a photodissociation reaction involving the pyridine ligand (Φdiss ∼ 0.025). This latter photoreaction provides an intermol. path for the cis → trans isomerization since its products (namely, free pyridine and Pt-containing species) recombine thermally to give cis- and trans-Pt(py)2Cl2 in a 2:1 ratio. The trans isomer undergoes photoisomerization and pyridine release but with much lower quantum yields (∼0.001). Qual. results concerning the photochem. behavior of the above complexes in MeOH solutions upon 254 or 313 nm irradiation are also reported.

A systematic study on intracellular Pt uptake and Pt accumulation ratio in breast cancer MCF-7 cell line has been performed on a number of Pt(II)-complexes, namely cisplatin, carboplatin and oxaliplatin, clin. employed as antitumor drugs, trans- and cis-[Pt(Cl)2(pyridine)2] and cis-[Pt(Cl)2(pyridine)(5-SO3H-isoquinoline)] complexes, previously investigated also as potential telomerase inhibitors. In particular, long incubation times have been chosen in order to understand the fate of the complexes in the cells. For this purpose, sub-acute drug concentrations must be employed and, therefore, a very sensitive method of anal. like as inductively coupled plasma mass spectrometry (ICP-MS) superior to the widely employed at. absorption spectroscopy (AAS) has been adopted. Any relationships among uptake/accumulation and several parameters such as drug structure, lipophilicity, drug concentration and incubation time have been sought and analyzed: the bulk of data point for a passive diffusion mechanism through the cell membrane.

A novel, water-soluble trans-platinum complex was synthesized by inclusion complexation with β-cyclodextrin. The complexation was confirmed by 1H NMR, FT-IR, TGA, and XRD as well as by SEM and EDX. As the precursor complex is not water-soluble, it is difficult to employ it for biol. applications. Here, we report that the encapsulation with cyclodextrin allowed to solubilize the complex to a solubility value of 1.6 mg/mL. Moreover, the cytotoxicity in vitro of the novel inclusion complex indicated a much higher activity after encapsulation.

Representative complexes are also active against L1210 cells in 2-h pulse exposures, as well as against the cisplatin-resistant variant L1210/DDP and human colonic carcinoma cell lines HT 29 and BE. Three complexes [Pt(NRCH2)2L2] (R = p-HC6F4, C6F5, or p-IC6F4) have good activity (T/C ≥ 180%) against P388 leukemia in mice, and all other compounds tested are active except when R = p-C6F5C6F4, L = py.

Platinum(II) complexes [PtA2X2], where A is ligand: ammonia (NH3), pyridine (Py); and X is ligand: chloride ion (CI-), bromide ion (Br-), iodide ion (I-), thiocyanato ion (SCN-); four compounds have different structural formulas ([Pt(NH2OH)2(NH3)2]Cl2), and cis-/trans-Pt(Gly)2, where Gly is bidentate glycinato ligand were examined for their antiproliferative activity in HeLa cells. Results of the MTT assay, showed that six cis- and one trans-platinum(II) complexes exhibited cytotoxicity (IC50) ranging between 5 and 33 μM. Most of the cis-platinum(II) isomers caused significant alteration of cell cycle phases progression, and induced apoptosis in degree that varied among different compounds, as evaluated using flowcytometry and morphol. study. Spectrophotometric anal. (AAS) indicated that there is no correlation between intracellular platinum(II) accumulation and cytotoxicity of tested complexes.
