生物活性 | Jaceosidin is a flavonoid isolated fromArtemisia vestita, inducesapoptosisincancercells, activatesBaxand down-regulatesMcl-1and c-FLIP expression[1]. Jaceosidin exhibits anti-cancer[2], anti-inflammatory activities, decreases leves of inflammatory markers, and suppressesCOX-2expression andNF-κBactivation[3]. |

体外研究 (In Vitro) | 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].
Cell Viability Assay[2] Cell Line: | Hec1A, KLE, HES and HESC cells | Concentration: | 3.125, 6.25, 12.5, 25, 50, and 100 μM | Incubation Time: | 48 hour | Result: | Showed cytostatic activity to HES and HESC cells with IC50s of 52.68 and 55.10 μM, less cytotocxic on Hec1 A and KLE (IC50, 70.54, 147.14 μM). |

体内研究 (In Vivo) | 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].
Animal Model: | 5-week-old male BALB/c mice (23-26 g)[3] | Dosage: | 10 and 20 mg/kg | Administration: | P.O. once a day for 3 days | Result: | Decreased the volumes of exudates (inflammatory markers), cell number and protein levels. Inhibited TNF-α by 46.7% and 50.8%, IL-1β by 46.0% and 44.7%, and PGE2 by 21.7% and 16.9%, respectively, at 20 mg/kg. Blocked COX-2 expression and NF-κB activation. |
Animal Model: | Male Sprague-Dawley rats (180-200 g)[3] | Dosage: | 20 mg/kg | Administration: | P.O., for 2 hour | Result: | Reduced hind paw edema volume by 27.1% at 1 h, and 24.0% at 2 h, respectively. |
