Hederagenin is a triterpenoid saponin. It can inhibit LPS-stimulated expression of iNOS, COX-2, and NF-κB Hederagenin can Exhibits multiple pharmacological activities in the treatment of hyperlipidemia, antilipid peroxidation, antiplatelet aggregation, liver protection, antidepression, anti-inflammation.[1] In vitro:1) Hederagenin can correct the imbalance of endothelial function by inhibiting the release of large amounts of iNOS and increasing eNOS contents and inhibits the IKKβ/NF-κB signaling pathway to reduce the release of IL-6, IFN-γ, TNF-α, and other inflammatory factors. [1] 2) The EC50 of hederagenin is 39 ± 6 μM in A549 cancer cell line, but it’s inactive for DLD-1 cells. [2] 3) Hederagenin inhibited LPS-induced production of NO, PGE2and cytokines in cells.[3] 4) Hederagenin had an anti-edema effect on the CA-induced mouse hind paw edema assay. [3] 5) Hederagenin inhibited the CA-induced increase in skin thicknesses. [3] In vivo: The rats in the hederagenin group were administered hederagenin at 20 mg/kg/d via gavage.(More details please refer to the protocol below). In AS rat models induced by a high-lipid diet plus VD3, hederagenin can effectively reduce serum lipid, ALT, and AST levels, in addition to improving liver function, relieving high blood coagulation, and slowing blood flow and stasis by improving blood rheology.

Hederacolchiside A1, isolated from Pulsatilla chinensis, suppresses proliferation of tumor cells by inducing apoptosis through modulating PI3K/Akt/mTOR signaling pathway[1]. Hederacolchiside A1 has antischistosomal activity, affecting parasite viability both in vivo and in vitro[2].

体外研究 (In Vitro)
Hederacolchiside A1 reduces the mitochondrial membrane potential and Bcl-2 protein levels, whereas cleaved caspase-3 was higher[1]. Hederacolchiside A1 effectively inhibits the phosphorylations of phosphatidylinositol 3 kinase (PI3K), protein kinase B (Akt), and mammalian target of rapamycin (mTOR) [1].

体内研究 (In Vivo)
hederacolchiside A1 (3.0, 4.5, and 6.0 mg/kg, ip) can significantly inhibit the weight of tumor in an H22 xenograft model[1]. Hederacolchiside A1 (3.25, 7.5, and 15.0 mg/kg, ig) can significantly inhibit the weight of tumor in nude mice xenograft tumor models using human breast carcinoma MCF-7 cells[1].
