Columbamine suppresses the proliferation and neovascularization of metastatic osteosarcoma U2OS cells with low cytotoxicity.[Pubmed: 23124089]
Columbamine (COL), an active component of the herb Coptis chinensis, inhibited the proliferation and neovascularization of metastatic osteosarcoma U2OS cells.
METHODS AND RESULTS:
Columbamine effectively suppressed U2OS cell proliferation in vitro with an IC(50) of 21.31±0.38μM, with low cytotoxicity. Mechanistic studies revealed that Columbamine induces cell cycle arrest at the G2/M transition, which is associated with attenuating CDK6 gene expression and diminishing STAT3 phosphorylation. Columbamine did not significantly promote U2OS cell apoptosis at any of the dosages tested. Additionally, Columbamine inhibited U2OS cell-mediated neovascularization, which was accompanied by the down-regulation of matrix metalloproteinase (MMP) 2 expression and reduction of cell migration, adhesion, and invasion. Taken together, our data show that Columbamine exerts anti-proliferative and anti-vasculogenic effects on metastatic human osteosarcoma U2OS cells with low toxicity.
CONCLUSIONS:
These results warrant further investigation of Columbamine as a potential anti-osteosarcoma and anti-cancer drug.

Storage: 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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Anticholinesterase inhibitory activity of quaternary alkaloids from Tinospora crispa.[Pubmed: 24448061]
Quaternary alkaloids are the major alkaloids isolated from Tinospora species. A previous study pointed to the necessary presence of quaternary nitrogens for strong acetylcholinesterase (AChE) inhibitory activity in such alkaloids.
METHODS AND RESULTS:
Repeated column chromatography of the vine of Tinospora crispa extract led to the isolation of one new protoberberine alkaloid, 4,13-dihydroxy-2,8,9-trimethoxydibenzo[a,g]quinolizinium (1), along with six known alkaloids-dihydrodiscretamine (2), Columbamine (3), magnoflorine (4), N-formylannonaine (5), N-formylnornuciferine (6), and N-trans-feruloyltyramine (7). The seven compounds were isolated and structurally elucidated by spectroscopic analysis. Two known alkaloids, namely, dihydrodiscretamine and Columbamine are reported for the first time for this plant. The compounds were tested for AChE inhibitory activity using Ellman's method. In the AChE inhibition assay, only Columbamine (3) showed strong activity with IC50 48.1 µM.
CONCLUSIONS:
The structure-activity relationships derived from these results suggest that the quaternary nitrogen in the skeleton has some effect, but that a high degree of methoxylation is more important for acetylcholinesterase inhibition.
