Lannotinidines H-J, new Lycopodium alkaloids from Lycopodium annotinum.
Three new Lycopodium alkaloids, lannotinidines H-J (1-3), were isolated from the club moss Lycopodium annotinum. The structures and relative stereochemistry of 1-3 were elucidated on the basis of spectroscopic data and the absolute stereochemistry of 2 was assigned by chemical correlation. Lannotinidine H (1) is the first Lycopodium alkaloid possessing a lycopodane skeleton with an additional C...
متن کاملTen new Lycopodium alkaloids having the lycopodane skeleton isolated from Lycopodium serratum Thunb.
Ten new alkaloids, lycoposerramines-F (1), -G (2), -H (3), -I (4), -J (5), -K (6), -L (7), -M (8), -N (9), and -O (10), having lycopodine-related structures, were isolated from the club moss Lycopodium serratum THUNB. and their structures were elucidated on the basis of spectroscopic analysis and/or chemical transformation.
متن کاملThe Genus Diphasiastrum and Its Lycopodium Alkaloids.
The genus Diphasiastrum includes at least 23 species distributed primarily across the northern temperate and subarctic areas of the world. These plants produce an array of lycopodium alkaloids, and some species such as Diphasiastrum complanatum have been used in traditional medicine for ages for various conditions. Hybridization is common in this group of plants and they have always been a chal...
متن کاملAsthma following occupational exposure to Lycopodium clavatum in condom manufacturers.
Occupational asthma in two women employed in the manufacture of condoms is reported. The spores of Lycopodium clavatum, used as a rubber dusting agent, were identified as the causative agent.
متن کاملDo small spores disperse further than large spores?
In species that disperse by airborne propagules an inverse relationship is often assumed between propagule size and dispersal distance. However, for microscopic spores the evidence for the relationship remains ambiguous. Lagrangian stochastic dispersion models that have been successful in predicting seed dispersal appear to predict similar dispersal for all spore sizes up to -40 microm diameter...
