SST-02 is a potent cationic lipid for siRNA-Lipid Nanoparticles. SST-02 possesses a simple chemical structure and is synthesized just in one step. SST-02 showed an ID50 of 0.02 mg kg in the factor VII (FVII) model. Rats administered with 3 mg kg of SST-02
Dios-Arg is a steroid-based cationic lipid that contains a diosgenin skeleton coupled to an L-arginine head group. It forms a complex with plasmid DNA and decreases plasmid DNA migration in an agarose-gel retardant assay at charge ratio greater than or equal to 4. Dios-Arg facilitates transfection of plasmid DNA into H1299 and HeLa cells in the presence and absence of fetal bovine serum, an effect that is reversed by the lipid raft-mediated endocytosis inhibitor methyl-β-cyclodextrin and the caveolae-mediated endocytosis inhibitor genistein . It has been used, coupled to 1,2-dioleoyl-sn-glycero-3-PE , to bind siRNA and plasmid DNA to form cationic lipid nanoparticles for intracellular transport. Dios-Arg is cytotoxic to H1299 and HeLa cells (IC50s = 83.5 and 74.1 μg/ml, respectively).
OH-C-Chol is a cationic cholesterol derivative. OH-C-Chol, as a component of lipoplexes with DOPE , has been used for siRNA delivery and gene silencing in MCF-7 cells as well as in mice via intravenous injection, resulting in lipoplex accumulation in the liver.
OH-Chol is a cationic cholesterol derivative.1 OH-Chol, as a component of lipoplexes with DOPE , has been used for siRNA delivery and gene silencing in MCF-7 cells, as well as in mice via intravenous injection, resulting in lipoplex accumulation in the liver. It has also been used in cationic nanoparticles in combination with Tween 80 to transfect pDNA and siRNA into PC3 mouse xenografts via intratumoral injection and with Tween 80 and folate-PEG2000-DSPE in a KB mouse xenograft model for intratumoral gene delivery.2References1.

MHAPC-Chol is a cationic cholesterol. MHAPC-Chol, as part of a lipoplex with DOPE , has been used for siRNA delivery and gene silencing in MCF-7 cells in a luciferase assay without affecting cell viability. It has also been used to deliver siRNA into mice via intravenous injection, resulting in MHAPC-chol accumulation in the liver.
