DMHAPC-Chol is a cationic cholesterol. Liposomes containing DMHAPC-chol have been used for DNA plasmid delivery in vitro and in vivo in a B16-F10 mouse xenograft model. Liposomes containing DMHAPC-chol are cytotoxic to B16-F10 cells when used at lipid concentrations greater than 20 μM. DMHAPC-Chol, as part of a lipoplex with DOPE , has also been used to deliver DNA into mouse lung via intratracheal injection, resulting in a heterogeneous distribution in the bronchi and bronchioles, and to deliver VEGF siRNA into A431 and MDA-MB-231 cells, which secrete VEGF.
RJ-34, an aristolactam analogue, demonstrates strong antitumor effects across a wide range of cancer cell lines, with subnanomolar GI 50 values (GI 50 <0.1 nM) observed for A431, MES-SA, MES-SA DX5, HCT-15, and HCT-15 CLO2 cells [1].
