Notoginsenoside Ft1 is an orally active bioactive saponin. Notoginsenoside Ft1 inhibits the PI3K/AKT/mTOR signaling pathway, activates the p38 MAPK and ERK1/2 signaling pathways, and increases the proportion of CD8⁺ T cells, thereby inducing apoptosis and lysosomal cell death in various cancer cells, and promoting angiogenesis. Notoginsenoside Ft1 causes vasodilation by activating glucocorticoid receptors (GR) and estrogen receptor beta (ERβ) in endothelial cells. Notoginsenoside Ft1 increases intracellular Ca²⁺ accumulation, reduces cAMP levels by activating a signaling network mediated through P2Y₁₂ receptors, and promotes platelet aggregation, thereby exerting a procoagulant effect. Notoginsenoside Ft1 inhibits ferroptosis (ferroptosis) in renal tubular epithelial cells by activating the TGR5 receptor, thereby demonstrating a renal protective effect. Notoginsenoside Ft1 acts as a TGR5 agonist and an FXR antagonist to combat obesity and insulin resistance.

Alternariol is an orally ingested mycotoxin produced by Alternaria, capable of inhibiting the activity of topoisomerase I and II (topoisomerase I, topoisomerase II). Alternariol has weak estrogenic (Estrogen Receptor/ERR) and androgen/antiandrogen (Androgen Receptor) effects. Alternariol can induce apoptosis, trigger cell cycle arrest, suppress innate immune responses, and exhibit anti-tumor activity. Alternariol has genotoxic, mutagenic, and endocrine-disrupting effects.

Licoflavone C is a broad-spectrum antiviral inhibitor with estrogen-like properties. Licoflavone C binds to viral endonuclease (CEN) and inhibits the replication of various bunyaviruses including severe fever with thrombocytopenia syndrome virus (SFTSV) and lymphocytic choriomeningitis virus in a non-substrate competitive manner. The IC₅₀ values of Licoflavone C against SFTSV CEN and SFTSV CEN are 35.5 μM and 135.8 μM, respectively, and its K_d value against SFTSV CEN is 9.53 μM. After viral entry into cells, Licoflavone C reduces viral loads in mouse tissues in a dose-dependent manner, and exhibits extremely low cytotoxicity and genotoxicity. Licoflavone C induces apoptosis by increasing caspase 3/7 activity, blocks the cell cycle, and alleviates chemotherapy-induced chromosomal damage. Licoflavone C is applicable to the research on severe fever with thrombocytopenia syndrome and related viral infection mechanisms.
