Liposomes as vehicles for water insoluble platinum-based potential drug: 2-(4-(Tetrahydro-2H-pyran-2-yloxy)-undecyl)-propane-1,3-diamminedichloroplatinum(II)

Formulation of liposome delivery system loaded with water insoluble 2-(4-(tetrahydro-2H-pyran-2-yloxy)-undecyl)-propane-1,3-diamminedichloroplatinum(II), LipoTHP-C11 was carried out. The particle size distributions were determined by dynamic light scattering and asymmetrical flow field-flow fractionation indicating size of around 120 nm. Stability study showed that LipoTHP-C11 was stable at 4 degrees C for more than two months. To test suitability of chosen formulation, LipoTHP-C11 was investigated against several tumor cell lines: H12.1, 1411HP, 518A2, A549, HT-29, MCF-7 and SW1736. Furthermore, toxicity against normal fibroblasts was examined. LipoTHP-C11 may be used as an attractive candidate for further assessment in vivo as antitumor agent. (C) 2012 Elsevier Masson SAS.
