简介内容: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 mg/kg in the factor VII (FVII) model. Rats administered with 3 mg/kg of SST-02 LNP did not show changes in body weight, blood chemistry, or hematological parameters, while the AST level decreased at a dose of 5 mg/kg. The use of SST-02 avoids a lengthy synthetic route and may thus decrease the future cost of nucleic acid
