| Hazard Information | Back Directory | [Uses]
A constitutent of frankincense (olibanum) with anti-inflammatory properties. It has been shown to trigger apoptosis via a pathway dependent on caspase-8 activation but independent on Fas/Fas ligand interaction in colon cancer HT-29 cells. | [Biological Activity]
37.9 μm: blocks a2780 (cis-platin resistant ovarian cancer cells) [1].11-keto-β-boswellic acid, known as kba, is a naturally occurring pentacyclic triterpene isolated from the gum resin of the tree boswellia serrata. kba is non-redox, specific leukotriene synthesis inhibitors through the inhibition of 5-lipoxygenase (5-lox) which has anti-arthritic and anti-inflammatory activities. 5-lox catalyzes essential fatty acids substrates into leukotrienes and a variety of other biologically active products. kba is a novel activator of nuclear factor erythroid-2-related factor 2 (nrf2), which protects against cerebral ischemic injury. | [in vitro]
kba, concentration dependently, decreased the formation of leukotriene b4 and the synthesis of all 5-lox products from endogenous arachidonic acid in rat peritoneal neutrophils. in contrast, kba exerted no remarkable effects on the 12-lipoxygenase and cyclooxygenase activities. [2]. | [in vivo]
adult male sprague–dawley rats were injected kab intraperitoneally at a dose of 25 mg/kg for 48 hours. kab remarkably decreased infarct volumes as well as apoptotic cells at 1 h, and then increased neurologic scores when applied 48 h. moreover, posttreatment with kba induced the decrease of malondialdehyde levels and the increase of protein nrf2 and heme oxygenase-1 expression in brain tissues, indicating that the nrf2/ho-1 pathway was involved in the neuroprotection of kba against oxidative stress-induced ischemic injury [3]. | [IC 50]
