Bakkenolide B 是从 petasites japonicas 叶片中分离出来的，具有抗过敏和抗炎作用。 Bakkenolide B 可用于研究哮喘。
Bakkenolide B (0-100 μg/ml; pretreatment 30 mins) inhibits antigen-induced β-hexosamidase release from RBL2H3 mast cells in a concentration-dependent manner.Bakkenolide B (0-10 μg/ml; 1 h later stimulated with LPS) strongly inhibits the gene inductions of inducible nitric oxide synthase and cyclooxygenase-2 in a concentration-dependent manner in mouse peritoneal macrophages.
Western Blot Analysis
| Cell Line: | Mouse peritoneal macrophages |
| Concentration: | 0 μg/ml; 1 μg/ml; 3 μg/ml; 5 μg/ml; 10 μg/ml |
| Incubation Time: | 1 h later stimulated with LPS |
| Result: | Decreased iNOS and cox-2 protein expression. |
Bakkenolide B (intraperitoneal injection; 1 mg/ml; 1 h before ovalbumin nebulization on days 28, 29, and 30) strongly inhibits the accumulation of eosinophils, macrophages, and lymphocytes to bronchoalveolar lavage fluid (BALF) in ovalbumin-induced asthma mice.
| Animal Model: | Ovalbumin-induced asthma mice |
| Dosage: | 1 mg/ml |
| Administration: | Intraperitoneal injection; 1 h before ovalbumin nebulization on days 28, 29, and 30 |
| Result: | Exhibited anti-allergic effects in mice. |
