Abstract:We showed di[3,5-diacetyl-1,2,4-triazolbis(4-cyclohexylthiosemicarbazonato) platinum(
II)] complex, (W8), endowed with important antitumor properties. Here, we analysed whether
W8 can affect human bone marrow-derived Mesenchymal Stem Cells, (hMSCs), involved in tissue
repair, immunomodulatory properties and also capacity for homing to injure-tumor sites in ovarian
cancer. Specifically, we analysed the effect of W8 on cell proliferation, response to scratch, and
whether copper-derived cellular mechanism is used by this platinum(II) complex being studied. Results showed that W8
causes a significant inhibition of cell proliferation at µM concentration. This effect is directly related to the alteration of
cytoskeletal proteins and inhibition of the response to scratch induced by the presence of foetal bovine serum. This
strongly supports the notion of W8 triggers the energetic metabolism of hMSCs and adds an extra support by the results
showing W8 relationship with the cellular copper ions. W8, acting in hMSCs, regulates in addition the inhibition of cell
proliferation, the inhibition of tumor angiogenesis and metastasis.
