631-69-6 Usage
Description
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).
Chemical Properties
BETA-BOSWELLIC ACID is Off-White Solid
Uses
The principal constitutents of frankincense (olibanum). A specific, nonredox inhibitor of 5-lipoxygenase used to treat inflammation.
Anticancer Research
It is a natural pentacyclic triterpenediol and occurs in Boswellia serrata plants as anisomeric blend of 3α, 24-dihydroxyolean-12-ene and 3α, 24-dihydroxyurs-12-ene.It induces apoptosis in various cancer cells. The events involved in this process areexcessive reactive oxygen species (ROS), nitric oxide (NO) formation, DNA ladderformation, and increased sub-G0 phase in cell cycle. This ultimately results incleavage of Bcl-2 and translocation of Bax to mitochondria, which lead to the lossof mitochondrial potential and release of cyt-c and other factors into cytosol. All these events are linked with reduced expression of survivin and inhibitor of caspase-activatedDNases (ICAD) that leads to the activation of poly(ADP-ribose) polymerase(PARP). The triterpene upregulates the expression of cell death receptor-4(DR-4) and tumor necrosis factor receptor-1 (TNF-R1), where both lead to activationof caspase-8 (Huang et al. 2000; Desai et al. 2008; Lu et al. 2008).
Check Digit Verification of cas no
The CAS Registry Mumber 631-69-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 631-69:
(5*6)+(4*3)+(3*1)+(2*6)+(1*9)=66
66 % 10 = 6
So 631-69-6 is a valid CAS Registry Number.

In the current investigation, a series of heterocyclic derivatives of boswellic acids were prepared along with new monomers of 3-O-acetyl-11-keto-β-boswellic acid (AKBA, 1) 11-keto-β-boswellic acid (KBA, 2) and several new bis-AKBA and KBA homodimers and AKBA-KBA heterodimers. The effects of these compounds on the proliferation of different human cancer cell lines, viz., FaDu (pharynx carcinoma), A2780 (ovarian carcinoma), HT29 (colon adenocarcinoma), and A375 (malignant melanoma), have been evaluated. Thus, KBA homodimer 21 effectively inhibited the growth of FaDu, A2780, HT29, and A375 cells with EC50 values below 9 μM. In addition, compounds 7, 8, 11, 12, 15, 16, and 17 also exhibited cytotoxic effects for A2780, HT29, and A375 cancer cells. In particular, the pyrazine analog 8 was highly cytotoxic for A375 cancer cells with an EC50 value of 2.1 μM.
