Composition of Triterpene Glycosides of the Far Eastern Sea Cucumber Levin et Stepanov; Structure Elucidation of Five Minor Conicospermiumosides A-1, A-2, A-3, A-1, and A-2; Cytotoxicity of the Glycosides Against Human Breast Cancer Cell Lines; Structure-Activity Relationships.

Five new non-holostane di- and trisulfated triterpene pentaosides, conicospermiumosides A-1 (), A-2 (), A-3 (), A-1 (), and A-2 () were isolated from the Far Eastern sea cucumber Levin et Stepanov (Cucumariidae, Dendrochirotida). Twelve known glycosides found earlier in other species were also obtained and identified. The structures of new compounds were established on the basis of extensive analysis of the 1D and 2D NMR spectra, as well as by the HR-ESI-MS data.

Adipose gene expression profiles in Northern Finncattle, Mirandesa cattle, Yakutian cattle and commercial Holstein cattle.

The drastic change in global climate has led to in-depth studies of the geneticresources of native cattle adapted to challenging environments. Native cattle breeds may harbor unique genetic mechanisms that have enabled them adapt to their given environmental conditions. Adipose tissues are key factors in the regulation of metabolism and energy balance and are crucial for the molecular switches needed to adapt to rapid environmental and nutritional changes.

Stonikacidin A, an Antimicrobial 4-Bromopyrrole Alkaloid Containing L-Idonic Acid Core from the Northwestern Pacific Marine Sponge .

Stonikacidin A (), the first representative of a new class of 4-bromopyrrole alkaloids containing an aldonic acid core, was isolated from the marine sponge . The compound is named in honor of Prof. Valentin A.

New Zosteropenillines and Pallidopenillines from the Seagrass-Derived Fungus KMM 4679.

Ten new decalin polyketides, zosteropenilline M (), 11--8-hydroxyzosteropenilline M (), zosteropenilline N (), 8-hydroxyzosteropenilline G (), zosteropenilline O (), zosteropenilline P (), zosteropenilline Q (), 13-dehydroxypallidopenilline A (), zosteropenilline R () and zosteropenilline S (), together with known zosteropenillines G () and J (), pallidopenilline A () and 1-acetylpallidopenilline A (), were isolated from the ethyl acetate extract of the fungus KMM 4679 associated with the seagrass . The structures of isolated compounds were established based on spectroscopic methods. The absolute configurations of zosteropenilline Q () and zosteropenilline S () were determined using a combination of the modified Mosher's method and ROESY data.
