reconstituted cell culture medium, a property useful as a drug carrier. TmC–GR–PY+‐Chol selectively enhanced the cell death (apoptosis) of the transformedcancercells compared to normal cells. This potency is found to be true for a wide range of transformedcancercells viz. HeLa, A549, ras oncogene‐transformed NIH3T3, HepG2, MDA‐MB231, MCF‐7, and HEK293T compared to the normal cell HEK293 in vitro
In this study, we synthesized a new galactosylated cationic lipid and investigated its biological activity. The structure of lipid combines both spermine residue for DNA compaction and galactose moiety for the improvement of aggregation behavior of lipoplexes. Lipid was low toxic for different mammalian cells, and was able both to compact plasmid DNA and to mediate cellular accumulation of various nucleic acids (ODN, pDNA and siRNA) exhibiting biological activity (transgene expression, gene silencing).
