| 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. |

Lycopodium Alkaloids: Lycoplatyrine A, an Unusual Lycodine-Piperidine Adduct from Lycopodium platyrhizoma and the Absolute Configurations of Lycoplanine D and Lycogladine H.[Pubmed:30698428]
J Nat Prod. 2019 Feb 22;82(2):324-329.
Three new Lycopodium alkaloids comprising two lycodine-type alkaloids (1, 2) and one fawcettimine alkaloid (3), in addition to 16 known alkaloids, were isolated from Lycopodium platyrhizoma. The structures of these alkaloids were elucidated based on analysis of their NMR and MS data. Lycoplatyrine A (1) represents an unusual lycodine-piperidine adduct. The structures and absolute configurations of lycoplanine D (hydroxy-des- N-methyl-Alpha-Obscurine, 10) and lycogladine H (11) were confirmed by X-ray diffraction analysis.
Lycodine-Type Lycopodium Alkaloids from the Whole Plants of Huperzia serrata.[Pubmed:28744720]
Nat Prod Bioprospect. 2017 Oct;7(5):405-411.
Three new lycodine-type Lycopodium alkaloids, namely 1-methyllycodine (1), 8alpha-hydroxy-15,16-dehydro-des-N-methyl-Alpha-Obscurine (2), N-methyl-16-hydroxyhuperzine B (3), and one new natural lycodine-type Lycopodium alkaloid, N-methylhuperzine A (4), along with 11 known analogues (5-15), were isolated from the whole plants of club moss Huperzia serrata. The structures of 1-4 were elucidated on the basis of NMR spectroscopic and mass spectrometry data. Among them, compound 1 was the first lycodine-type alkaloid possessing a methyl group at C-1. In addition, the structure of 5 was confirmed by the single-crystal X-ray crystallography data and its (13)C NMR was reported for the first time in current study. Compounds 1-5 were tested their BACE1 inhibitory activity.
Isolation of a new lycodine alkaloid from Lycopodium japonicum.[Pubmed:25421949]
Nat Prod Res. 2015;29(8):735-8.
A new lycodine alkaloid, N-methylhydroxypropyllycodine (1), was isolated from the club moss Lycopodium japonicum Thunb, together with five known compounds, N-methyllycodine (2), huperzinine (3), beta-obscurine (4), Alpha-Obscurine (5) and des-N-methyl-Alpha-Obscurine (6). Their structures were elucidated by spectroscopic analyses, including 2D NMR techniques.
[Study on chemical constituents of Lycopodium alkaloids].[Pubmed:22667147]
Zhongguo Zhong Yao Za Zhi. 2012 Feb;37(4):475-7.
OBJECTIVE: To study the alkaloid chemical constituents of Lycopodium japonicum. METHOD: Compounds were isolated and purified by such methods as silica gel column chromatography, RP-C18 reversed phase column chromatography, Sephadex LH-20 column chromatography and Waters semi-preparative liquid chromatogram, and their structures were identified based on physicochemical property and spectrum data. RESULT: Nine known alkaloid chemical constituents were isolated and identified, they were lycodoline (1), lucidioline (2), Alpha-Obscurine (3), lycopodine (4), lycoposerramine-L (5), lycoposerramine-M (6), 11alpha-O-acetyl-lycopodine (7), des-N-methyl-a-obscurine (8), clavolonine (9). CONCLUSION: Compounds 4-9 were obtained from L. japonicum for the first time.
