Jaceosidin is a flavonoid isolated from Artemisia vestita, induces apoptosis in cancer cells, activates Bax and down-regulates Mcl-1 and c-FLIP expression[1]. Jaceosidin exhibits anti-cancer[2], anti-inflammatory activities, decreases leves of inflammatory markers, and suppresses COX-2 expression and NF-κB activation[3].

Jaceosidin (30, 50, 75 μM) induces apoptosis in human renal carcinoma Caki cells after treatment for 24 h, shows no obvious effect on normal cells[1].Jaceosidin (75 μM) reduces MMP levels and causes cytochrome c release into the cytoplasm through Bax activation[1].Jaceosidin-mediated apoptosis is involved in downregulation of Mcl-1, c-FLIP expression, which is via inhibition of NF-κB and/or Sp1 transcriptional activity[1].Jaceosidin shows cytostatic activity to HES and HESC cells with IC50s of 52.68 and 55.10 μM, and is less cytotocxic on Hec1 A and KLE (IC50, 70.54, 147.14 μM, respectively), after treatment for 48 h[2].

Jaceosidin (10 and 20 mg/kg, p.o., once a day for 3 days) blocks carrageenan-induced increase in leukocyte number and protein levels in air pouch exudates in mice[3].Jaceosidin (10, 20 mg/kg, p.o.) suppresses COX-2 expression and NF-κB activation in mice[3].Jaceosidin (20 mg/kg, p.o. for 2 hours) reduces hind paw edema volume in rats[3].
