11-​Keto-​beta-​boswellic acid (Synonyms: 11-Keto-β-boswellic acid) 纯度: 99.60%

11-Keto-beta-boswellic acid (11-Keto-β-boswellic acid) 是一种五环三萜酸,来自俗称印度乳香 (Indian Frankincense) 的乳香树 (Boswellia serrate) 树皮的油树脂。 11-Keto-beta-boswellic acid 具有抗炎活性,主要是由于抑制 5-脂氧合酶 (5-lipoxygenase; 5-LOX)白三烯 (leukotriene)NF-κB的激活和肿瘤坏死因子 α 的产生。

生物活性

11-Keto-beta-boswellic acid (11-Keto-β-boswellic acid) is a pentacyclic triterpenic acid of the oleogum resin from the bark of the Boswellia serrate tree, popularly known as Indian Frankincense. 11-Keto-beta-boswellic acid has the anti-inflammatory activity is primarily due to inhibit 5-lipoxygenase (5-LOX) and subsequent leukotriene and nuclear factor-kappa B (NF-κB) activation and tumor necrosis factor alpha generation production[1].

生物活性

2-Keto-D-galactose (D-Galactosone) inhibits DNA synthesis, and inhibits proliferation of in vitro grown Ehrlich ascites tumor cells[1].

IC50 & Target

DNA synthesis[1]

体外研究
(In Vitro)

2 mM 2-Keto-D-galactose (Galactosone) causes a comparable inhibition of DNA synthesis. Proliferation of in vitro grown Ehrlich ascites tumor cells is completely inhibited by 1-2 mM 2-Keto-D-galactose without severely affecting viability (dye exclusion test); no phase-specific arrest of cell growth is observed[1].
