Human leukemic K562 cells can be induced in vitro to erythroid differentiation by a variety of chemical compounds, including hemin, butyric acid, 5-azacytidine, and cytosine arabinoside. Differentiation of K562 cells is associated with an increase in the expression of embryo-fetal globin genes, such as the zeta-, epsilon-, and gamma-globin genes. Therefore,(More)
In this study, we compared some bile acid derivatives and their platinum(II) complexes with respect to their ability to induce erythroid differentiation of human leukemic K562 cells. The complexes analyzed were cis-[(3-dehydrocholanoyliden-L-tartrate)-diammineplatinum(II)] (compound 1) and cis-[di(dehydrocholanoate)-bis(triphenylphosphine)-platinum(II)](More)
The strontium salts Sr(cholate)2, (Compound 1), Sr(dehydrocholate)2, (Compound 2) and Sr3(3-dehydrocholanoyliden-L-tartrate)2, (Compound 3) have been prepared and characterized. The potential anti-osteoporotic activity of these compounds was tested on human primary osteoblasts (hOBs) and human primary osteoclasts (hOCs) in comparison with the bioactivity of(More)

The use of solid lipid nanoparticles (SLN) is a promising route for the delivery of platinum complexes aimed to anticancer activity. This paper describes the production and characterization of SLN suitable for the loading of Pt complexes containing the biocompatible phosphine 1,3,5-triaza-7-phosphaadamantane (PTA) as neutral ligand. After a screening of(More)
