Chuanbeinone
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.

Chuanbeinone inhibits the growth of LLC, A2780, HepG2, and A549 cells with IC50 values of 10.51 μg/mL, 18.16 μg/mL, 37.97 μg/mL, and 43.74 μg/mL, respectively[1].
Chuanbeinone (5-15 μg/mL; 48 h) induces dose-dependent apoptosis in LLC cells, with apoptotic rates of 12.8% to 64.8%[1].
Chuanbeinone (10 μg/mL; 24-72 h) induces time-dependent S phase arrest and decreases the cells in the G0/G1 phase[1].
Chuanbeinone (5-15 μg/mL; 48 h) downregulates Bcl-2, upregulates Bax, and activates caspase-3 in LLC cells[1].
Chuanbeinone (20-100 μM; 24 h) reduces RAW 264.7 cell viability[2].
Chuanbeinone (5-20 μM; 24 h, co-treated with 0.2 μg/mL LPS) exerts anti-inflammatory effects on LPS (HY-D1056)-induced RAW 264.7 cells by reducing pro-inflammatory cytokine production and mRNA expression, and inhibiting TRIF-, MyD88-, NF-κB-, and MAPK-dependent signaling pathways[2].
Chuanbeinone inhibits AChE with an IC50 of 7.7 ± 0.001 μM and BChE with an IC50 of 0.7 ± 0.001 μM, and exhibits 70.7 ± 3.3% enzyme inhibition at 100
μM[3].
