General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Inhibitory effects of furoquinoline alkaloids from Melicope confusa and Dictamnus albus against human phosphodiesterase 5 (hPDE5A) in vitro.[Pubmed:16042076]
Arch Pharm Res. 2005 Jun;28(6):675-9.
Eight furoquinoline alkaloids were purified from two plants belonging to the Rutaceae family. Kokusaginine, skimmianine, evolitrine, and confusameline were purified from Melicope confusa, and haplopine, Robustine, dictamine, and gamma-fagarine from Dictamnus albus. In this study, the eight furoquinoline alkaloids were examined for inhibitory potency against human phosphodiesterase 5 (hPDE5A) in vitro. DNA encoding the catalytic domain of human PDE5A was amplified from the mRNA of T24 cells by RT-PCR and was fused to GST in an expression vector. GST-tagged PDE5A was then purified by glutathione affinity chromatography and used in inhibition assays. Of the eight alkaloids, gamma-fagarine was the most potent inhibitor of PDE5A, and its single methoxy group at the C-8 position was shown to be critical for inhibitory activity. These results clearly illustrate the relationship between PDE5A inhibition and the methoxy group position in furoquinoline alkaloids.
Neolignans, a coumarinolignan, lignan derivatives, and a chromene: anti-inflammatory constituents from Zanthoxylum avicennae.[Pubmed:18211005]
J Nat Prod. 2008 Feb;71(2):212-7.
Eight new compounds, including four new neolignans, (7' S,8' S)-bilagrewin ( 1), (7' S,8' S)-5-demethoxybilagrewin ( 2), (7' S,8' S)-5- O-demethyl-4'- O-methylbilagrewin ( 3), and (7' S,8' S)-nocomtal ( 4), a new coumarinolignan, (7' S,8' S)-4'- O-methylcleomiscosin D ( 5), two new lignan derivatives, (+)-9'- O-( Z)-feruloyl-5,5'-dimethoxylariciresinol ( 6) and (+)-9'- O-( E)-feruloyl-5,5'-dimethoxylariciresinol ( 7), and a new chromene, ( E)-3-(2,2-dimethyl-2 H-chromen-6-yl)prop-2-enal ( 8), have been isolated from the stem wood of Zanthoxylum avicennae, together with 18 known compounds ( 9- 26). The structures of these new compounds were determined through spectroscopic and MS analyses. (7' S,8' S)-4'- O-Methylcleomiscosin D ( 5), cleomiscosin D ( 9), skimmianine ( 18), Robustine ( 19), and integrifoliolin ( 23) exhibited inhibition (IC 50 < or = 18.19 microM) of superoxide anion generation by human neutrophils in response to formyl- l-methionyl- l-leucyl- l-phenylalanine/cytochalasin B (FMLP/CB). In addition, skimmianine ( 18) inhibited FMLP/CB-induced elastase release with an IC 50 value of 19.15 +/- 0.66 microM.
