||23-epi-26-Deoxyactein has anti-inflammatory activity, it inhibits nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. It also has anti-cancer activity, it can inhibit growth of the MCF7 human breast cancer cells and induce cell cycle arrest at G1. |

|Growth inhibitory activity of extracts and purified components of black cohosh on human breast cancer cells.[Pubmed: 14758092 ]|
|The purpose of this study was to determine whether black cohosh contains constituents that inhibit the growth of human breast cancer cells, and therefore might eventually be useful in the prevention or treatment of breast cancer. |
METHODS AND RESULTS:
Black cohosh rhizomes were extracted with methanol/water and fractionated by solvent-solvent partitioning to yield three fractions: hexane, ethyl acetate and water. The ethyl acetate fraction displayed the highest potency in two cell-based assays, growth inhibition and cell cycle analysis. This fraction inhibited growth of both the ER+ MCF7 and ER-MDA-MB-453 human breast cancer cell lines with IC50 values of about 20 and 10 micro g/ml, respectively. It also induced cell cycle arrest at G1 when tested at 30 micro g/ml and at G2/M at 60 micro g/ml in MCF7 cells. This suggests that the extract contains a mixture of components with the more active (or more abundant) causing G1 arrest and the less active causing G2/M arrest. We then examined specific components in this extract.
The triterpene glycoside fraction obtained by polyamide column chromatography, and the specific triterpene glycosides actein, 23-epi-26-Deoxyactein and cimiracemoside A, inhibited growth of the MCF7 human breast cancer cells and induced cell cycle arrest at G1.
METHODS AND RESULTS:
The most potent compound, actein, decreased the level of cyclin D1, cdk4 and the hyperphosphorylated form of the pRb protein and increased the level of p21cip1 in MCF7 cells, changes that may contribute to the arrest in G1. Further studies are in progress to identify the mechanisms by which actein and related compounds present in black cohosh inhibit growth of human breast cancer cells.

|Inhibition of inducible nitric oxide synthesis by Cimicifuga racemosa (Actaea racemosa, black cohosh) extracts in LPS-stimulated RAW 264.7 macrophages.[Pubmed: 19703353 ]|
|Cimicifuga racemosa (Actaea racemosa, black cohosh) is used as an anti-inflammatory, antipyretic and analgesic remedy in traditional medicines. The present study focuses on the effects of C. racemosa root extracts on inducible nitric oxide synthase (iNOS) in lipopolysaccharide-stimulated murine macrophages (RAW 264.7). |
METHODS AND RESULTS:
C. racemosa rhizome and phosphate-buffered saline extracts were analysed for phenolcarboxylic acids and triterpene glycosides using an HPLC photodiode array/evaporative light-scattering detector system. iNOS was characterised by measurement of iNOS protein (immunoblotting), iNOS mRNA (semiquantitative competitive RT-PCR), nitric oxide production (nitrite levels) and nuclear translocation of nuclear factor-kappaB (p65 subunit) protein. Incubation of lipopolysaccharide-stimulated macrophages with aqueous C. racemosa extracts (0-6 mg/ml) inhibited nitrite accumulation in a concentration-dependent manner. C. racemosa extracts also reduced iNOS protein expression and iNOS mRNA levels in a dose-dependent manner. C. racemosa extracts did not significantly inhibit iNOS activity and did not affect nuclear translocation of nuclear factor-kappaB (p65 subunit) protein. Incubation with the extract was associated with a concentration-dependent reduction of interferon beta and interferon regulatory factor 1 mRNA. Among the triterpene glycosides, 23-epi-26-Deoxyactein was identified as an active principle in C. racemosa extracts.
Extracts from the roots of C. racemosa inhibit nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. This might contribute to the anti-inflammatory activities of C. racemosa.

||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
