Evaluation of a Platinum-Acridine Anticancer Agent and Its Liposomal Formulation in an in vivo Model of Lung Adenocarcinoma.

ABSTRACT: Liposomal formulations have been developed for a highly cytotoxic platinum-acridine agent, [PtCl(pn)(C₁₈ H₂₁ N₄ )](NO₃ )₂ (PA, pn=propane-1,3-diamine), and fully characterized. Nanoliposomes consisting of hydrogenated soybean phosphatidylcholine (HSPC), 1,2-dihexadecanoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (DPPG), and polyethylene glycol-2000-distearoylphosphatidylethanolamine (DSPE-mPEG_2k ) were able to stably encapsulate PA at payload-to-lipid ratios of 2-20 %. The fusogenic properties of the liposomes promote efficient cellular uptake of PA across the plasma membrane, which results in vesicular transport of payload to the nucleus in cultured lung cancer cells. Unencapsulated PA and one of the newly designed liposomal
