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 کاملSome illustrations of information geometry in biology and physics ∗
Many real processes have stochastic features which seem to be representable in some intuitive sense as 'close to Poisson', 'nearly random', 'nearly uniform' or with binary variables 'nearly independent'. Each of those particular reference states, defined by an equation, is unstable in the formal sense, but it is passed through or hovered about by the observed process. Information geometry gives...

متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولTen 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.
