产品描述：
IC50: 35.8 μM: inhibits MCF-7 (human breast adenocarcinoma) [1].
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].
