生物活性

Rhapontigenin is a natural analog of resveratrol with anticancer, antioxidant, antifungal and antibacterial activities. Rhapontigenin is amechanism-based, potent and selective cytochrome P450 1A1 inactivator (IC50  = 400 nM). Rhapontigenin exhibits 400-fold and 23-fold selectivity for P450 1A1 over P450 1A2 and P450 1B1, respectively.

体外研究(In Vitro)

Rhapontigenin (0-250 μM; 24 hours) demonstrates concentration-dependent anti-cancer activity with an IC50 115μM in HEP G2 cells.
Rhapontigenin (20 μM; 20 hours) pre-treatment decreases TGF-β triggered increased snail expression in diverse cancer cells.
Rhapontigenin (0-20 μM; 6 hours) inhibits TGF-β-induced expression of N-cadherin, vimentin, and CA9 in a dose-dependent manner.
Rhapontigenin inhibits ADP- and collagen-induced platelet aggregation with IC50 values of 4 and 70 μg/ml, respectively.
Rhapontigenin demonstrates a strong inhibitory activity on the 13-hexosaminidase release induced by DNP-BSA, it exhibits IC50 value of 0.03 mM in RBL 2H3 cells.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
