Summary of "Lycofargesiines A-F, further Lycopodium alkaloids from the club moss Huperzia fargesii."

Six undescribed Lycopodium alkaloids (LAs) comprising four lycodine-type (lycofargesiines A-D), one lycopodine-type (lycofargesiine E), and a phlegmarine-type (lycofargesiine F), together with 16 known ones were isolated from the club moss Huperzia fargesii. Their structures and absolute configurations were determined by extensive spectroscopic methods, electronic circular dichroism (ECD) analysis, and density functional theory (DFT) calculations. (7S,8R,12R,13R)-Lycofargesiine A is a rare naturally occurring LA possessing an exocyclic double bond between C-15 and C-16, with ring A being a rare 2,3-dihyropyridone motif. Lycofargesiine D is an uncommon lycodine-type alkaloid featuring a unique N-acetylated tetrahydropyridinyl segment (ring A), whereas lycofargesiine F is the first phlegmarane-type LA bearing two nitrone moieties. In addition to the isolated huperzine A in this study, another two isolates (lycofargesiine C and 16-hydroxyhuperzine A) were also found to show inhibitory activities against acetylcholinesterase (AChE), with IC values of 8.63 and 5.18 μM, respectively.

Medical and Biotech [MESH] Definitions

A plant genus of the family LYCOPODIACEAE. Members contain ALKALOIDS. Lycopodium oil is obtained from L. clavatum.

A class of plants within the Bryophyta comprising the mosses, which are found in both damp (including freshwater) and drier situations. Mosses possess erect or prostrate leafless stems, which give rise to leafless stalks bearing capsules. Spores formed in the capsules are released and grow to produce new plants. (Concise Dictionary of Biology, 1990). Many small plants bearing the name moss are in fact not mosses. The "moss" found on the north side of trees is actually a green alga (ALGAE, GREEN). Irish moss is really a red alga (ALGAE, RED). Beard lichen (beard moss), Iceland moss, oak moss, and reindeer moss are actually LICHENS. Spanish moss is a common name for both LICHENS and an air plant (TILLANDSIA usneoides) of the pineapple family. Club moss is an evergreen herb of the family LYCOPODIACEAE.

The club-moss plant family of the order Lycopodiales, class Lycopodiopsida, division Lycopodiophyta, subkingdom Tracheobionta. The common name of clubmoss applies to several genera of this family. Despite the name this is not one of the true mosses (BRYOPSIDA ).

A plant genus of the family LYCOPODIACEAE. Members contain huperzine, one of the CHOLINESTERASE INHIBITORS.

Alkaloids originally isolated from the ergot fungus Claviceps purpurea (Hypocreaceae). They include compounds that are structurally related to ergoline (ERGOLINES) and ergotamine (ERGOTAMINES). Many of the ergot alkaloids act as alpha-adrenergic antagonists.
