In the absence of crystallographic data, NMR has emerged as the best way to define protein-ligand interactions. Using NMR experiments based on magnetization transfer, one can sort bound from unbound molecules, estimate the dissociation constant, iden

5α-Dihydrorubrosterone (2β, 3β, 14α, 17β-tetrahydroxy-5α-androst-7-ene-6-one), a new 19-carbon 5α-ecdysteroid, was isolated together with its 5β counterpart from the aerial parts of Silene otites L. (Wib.) (Caryophyllaceae) by a combination o

Poly(L-malic acid) was recently isolated for the first time from Physarum polycephalum, a myxomycete for which it plays the role of a coordinator during DNA replication. To determine the chain structure of this new natural polymer, its high-resolutio

A new phytoecdysteroid, 24(241)[Z]-dehydroamarasterone B, has been isolated from seeds of Leuzea (Rhaponticum) carthamoides. It has been unambiguously identified by CIMS, 13C NMR and 1H NMR spectroscopy. The biological activity of the ecdysteroid has

Sidisterone (1), the first C24 ecdysteroid, has been isolated from two species of the Caryophyllaceae in the genus Silene (S. dioica and S. otites) and identified through 1H-, 13C-, and multidimensional NMR and molecular modeling techniques.

Eleven ecdysteroids have been isolated from Lychnis floscuculi; we are the first who report eight ecdysteroids of the eleven compounds in this plant. Two of these ecdysteroids, dihydrorubrosterone and 20-hydroxyecdysone 3-acetate are newly discovered
