  Phospholipids are potential antineoplastic agents that are abundant constituents of the cell membrane of eukaryotes and are supposed to be involved in specific intracellular signaling such as cell death. The aim of this study was to assess the in vitro and in vivo antitumor effects of synthetic phosphoethalomanine (PHO-S) on B16F10 murine melanoma cells and normal human fibroblasts. The cytotoxicty was evaluated by MTT assay and PHO-S was cytotoxic in melanoma cells but not in fibroblasts with IC50% of 1.4 mg/ml to melanoma cells. In vivo antitumor activity was evaluated in a mice model subcutaneously injected with B16F10 melanoma cells. The mice treated with PHO-S in all concentrations showed a decrease of the tumor growth and metastasis. Cytometry analysis showed that the PHO-S blocked DNA synthesis, decreased number of melanoma cells in S phase and G2/M, besides increasing number o.. Read More»
