Tirucallol 是一种四环三萜，分离自Euphorbia lacteal乳胶。它能够抑制小鼠模型中的耳部水肿，并阻碍脂多糖刺激的巨噬细胞中亚硝酸盐的产生，具有局部消炎作用。

Tirucallol is an antiinflammatory agent isolated from Euphorbia lactea.Tirucallol exerts a topical anti-inflammatory effect in vivo, via a mechanism of action related to the neutrophil migration.

The effect of CMG neutral extract (25-200 microg/ml) and Tirucallol (0.1-100 microM) on the following: 1) the expression of adhesion molecules (VCAM-1 and ICAM-1) by Cell ELISA and 2) the attachment of monocytes (U937 cells) in TNF-alpha stimulated Human Aortic Endothelial Cells (HAEC) by Adhesion assay. The impact of treatment with CMG neutral extract and Tirucallol in NFkB phosphorylation was also examined by a cell-based ELISA kit. Both CMG extract and Tirucallol inhibit significantly VCAM-1 and ICAM-1 expression in TNF-alpha-stimulated HAEC. They also inhibit significantly the binding of U937 cells to TNF-alpha-stimulated HAEC and attenuate the phosphorylation of NFkB p65.
