Fritillaria pallidiflora Schrenk ex Fisch. & C. A. Mey.

Isoverticine, a bioactive isosteroidal alkaloid isolated from bulbus of Fritillaria pallidiflora, displays significant cytotoxicity.

Imperialine 3-β-D-glucoside is the glycoside of Imperialine (HY-N0696). Imperialine 3-β-D-glucoside may exhibit anti-tumor properties against multi-agent resistant tumor cells.

Protobioside is a steroidal saponin found in the dry bulbs of Fritillaria pallidiflora Schrenk. Protobioside shows no significant cytotoxic activity against human cancer cells.

Chuanbeinone (22-Epidelavinone) is an orally active alkaloid found in Fritillaria pallidiflora. Chuanbeinone shows cytotoxicity against mutiple cancer cells and can induces apoptosis and S phase arrest. Chuanbeinone downregulates Bcl-2, upregulates Bax, and activates caspase-3. Chuanbeinone exerts anti-inflammatory and antitussive effects by reducing pro-inflammatory cytokine (IL-1β, IL-6 and TNF-α) production and mRNA expression, and inhibiting TRIF-, MyD88-, NF-κB-, and MAPK-dependent signaling pathways. Chuanbeinone inhibits AChE and BChE with IC₅₀ values of 7.7 and 0.7 μM. Chuanbeinone can be used for the researches of lung carcinoma, cough, inflammatory diseases.

Delavinone (Sinpeinine A) is an alkaloid. Delavinone is suitable for electrospray ionization (ESI) positive electrode detection.
