Β‐ボスウェル酸

説明β-Boswellic acid is a pentacyclic triterpene originally isolated from Boswellia that has diverse bioactivities. It inhibits 5-lipoxygenase (5-LO) with an IC50 value of approximately 5 μM but is less potent than its derivative 3-acetyl-11-keto-β-boswellic acid . It inhibits cell proliferation in HL-60 cells with IC50 values of 3.7, 7.1, and 6.3 μM for DNA, RNA, and protein synthesis, respectively. In human umbilical vein endothelial cells (HUVECs) transiently deprived of oxygen and glucose, β-boswellic acid increases nitric oxide and increases phosphorylation of enzyme nitric oxide synthase (eNOS). It also increases calcium mobilization in platelets at concentrations ≥3 μM and induces platelet aggregation (EC50 = 8 μM).

使用The principal constitutents of frankincense (olibanum). A specific, nonredox inhibitor of 5-lipoxygenase used to treat inflammation.
