Description: Cauloside C, also known as Hederoside D2, is a triterpenoid saponin that induces potassium release and hemolysis in mouse erythrocytes in a pH-dependent manner. Hederoside D2 is cytotoxic to N1E-115 neuroblastoma cells at low pH. It induces proliferation of human embryonic fibroblasts in acidic medium, an effect that can be blocked by the calcium channel blockers verapamil, diltiazem, and nitrendipine.
