Chikusetsusaponin IVa is an oleanane-type triterpenoid that has been found in P. stipuleanatus and has diverse biological activities.1,2,3 It inhibits the growth of human HL-60 leukemia and HCT116 colon cancer cells (IC50s = 76.23 and 78.11 ?M, respectively).1 Chikusetsusaponin IVa (50-200 ?g/ml) reduces LPS-induced increases in inducible nitric oxide synthase (iNOS), COX-2, IL-1β, IL-6, and TNF-α levels in THP-1 macrophages differentiated with phorbol 12-myristate 13-acetate .2 It decreases plasma glucose, triglyceride, and LDL-cholesterol, and increases HDL-cholesterol, levels in a rat model of type 2 diabetes induced by streptozotocin and a high-fat diet when administered at doses ranging from 45 to 180 mg/kg.3 It also decreases malondialdehyde (MDA), and increases superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase 4 (GPX4), levels in the pancreas in the same model.
