Dauriporphine
Dauriporphine shows cytotoxic activity on the target cancer cell lines, and shows significant angiogenesis inhibitions. Dauriporphine shows significant inhibitions on receptor activator of nuclear factor-κB ligand-induced differentiation of mouse bone marrow-derived macrophages into multinucleated osteoclasts. Dauriporphine shows potent P-gp MDR inhibition activity with an ED50 value 0.03 microg/mL and 0.00010 microg/mL in the MES-SA/DX5 and HCT15 cells, respectively.

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.

Anti-osteoclastogenic effects of isoquinoline alkaloids from the rhizome extract of Sinomenium acutum.[Pubmed:
26992921]
METHODS AND RESULTS:
A phytochemical investigation for the rhizome extract from Sinomenium acutum (Menispermaceae) resulted in the isolation of several active principles responsible for the anti-osteoclastogenic property of the extract, together with related isoquinoline alkaloids (1-13) including two new compounds, 1 and 2. Among isolated compounds, salutaridine (7), dauricumine (10), cheilanthifoline (12), and Dauriporphine (13) were observed to give significant inhibitions on receptor activator of nuclear factor-κB ligand-induced differentiation of mouse bone marrow-derived macrophages into multinucleated osteoclasts, respectively.
CONCLUSIONS:
The chemical structures of two newly isolated compounds, 1 and 2 were established as 8-demethoxycephatonine (1) and 7(R)-7,8-dihydrosinomenine (2), by spectroscopic analyses including 2D NMR experiments.

Aporphine alkaloids and their reversal activity of multidrug resistance (MDR) from the stems and rhizomes of Sinomenium acutum.[Pubmed:
16964757]
METHODS AND RESULTS:
Chromatographic separation of the MeOH extract from the stems and rhizomes of Sinomemium acutum led to the isolation of nine alkaloids and a lignan. Their structures were determined to be Dauriporphine (1), bianfugecine (2), dauriporphinoline (3), menisporphine (4), (-)-syringaresinol (5), N-feruloyltyramine (6), acutumine (7), dauricumine (8), sinomenine (9), and magnoflorine (10) by spectroscopic means. These compounds were examined for their P-gp mediated MDR reversal activity in human cancer cells.
CONCLUSIONS:
Compound 1 showed the most potent P-gp MDR inhibition activity with an ED50 value 0.03 microg/mL and 0.00010 microg/mL in the MES-SA/DX5 and HCT15 cells, respectively.

New alkaloids and cytotoxic principles from Sinomenium acutum.[Pubmed:
23059629]
METHODS AND RESULTS:
Two new alkaloids, 2-demethyl-oxypalmatine (1) and 5-ethoxycarbonylsinoracutine (2), were isolated from the rhizomes of Sinomenium acutum, along with thirty-four known compounds. Cytotoxicity of the isolated compounds was examined for the MCF-7, H460, HT-29, and CEM human cancer cell lines.
CONCLUSIONS:
Dauriporphine (16), 6-O-demethylmenisporphine (17), bianfugecine (18), menisporphine (19), and 6-O-demethylDauriporphine (20) showed differential effects in their cytotoxic activity on the target cancer cell lines. Significant angiogenesis inhibitions of 16 and 19 were also observed.
