The influence of phospholipid on the physicochemical properties and anti-tumor efficacy of liposomes encapsulating cisplatin in mice bearing C26 colon carcinoma

SPI-077, cisplatin stealth liposome, is the best illustration of poor cisplatin release from liposomes and the subsequent negligible therapeutic activity. For this reason, optimizing drug release kinetics is desirable. In this report, cisplatin was encapsulated in liposomes composed of different phosphatidylcholines with various phase transition temperatures (Tm) (HSPC, DPPC, DMPC, soy phosphatidylcholine (SPC)), cholesterol and mPEG2000–DSPE....
