International workshop on "Modeling interaction in biomolecules IV", held in Hrubá Skála, 14-19 September 2009.
Total synthesis and absolute configuration of the natural amino acid tetrahydrolathyrine.
The natural product tetrahydrolathyrine has been synthesized through an iminoiodane-mediated aziridination of a (2S)-allylglycinol derivative, which provided a 2:3 mixture of diastereoisomers. One of these diastereoisomers was converted to the natural product and the other to its C-4 epimer. The C-4...
Model for heat and mass transfer in freeze-drying of pellets.
Lyophilizing frozen pellets, and especially spray freeze-drying, have been receiving growing interest. To design efficient and safe freeze-drying cycles, local temperature and moisture content in the product bed have to be known, but both are difficult to measure in the industry. Mathematical modeli...
Synthesis of spiroacetal-nucleosides as privileged natural product-like scaffolds.
The elaboration of a 6,6-spiroacetal scaffold to incorporate a nucleoside unit at the anomeric position is described. The novel spiroacetal-nucleoside hybrids were generated via nucleosidation of acetoxy-spiroacetal with a series of silylated nucleobases under VorbrÃ¼ggen conditions.

Antioxidant and Antiradical Activities of
Wu Ling Shen
in a Cell Free System
These results conclude that XN-E possesses the most potent antioxidant and antiradical activities, and that these activities could be derived from its high polyphenol content, but not the level of polysaccharides....

Organocatalytic asymmetric synthesis of versatile gamma-lactams.
Intense Vasoconstriction in Response to Aspirate From Stented Saphenous Vein Aortocoronary Bypass Grafts
Stent implantation releases, apart from and in addition to particulate debris, soluble vasoconstrictor substances that possibly contribute to impaired microvascular perfusion....
Switching from asexual to sexual reproduction in the planarian Dugesia ryukyuensis: change of the fissiparous capacity along with the sexual...
We found by analysis of the sexualization that the cessation of the fission, namely their asexual reproduction, occurs immediately after the acquisition of sexuality. This result suggests that the downstream mechanisms induced by the putative sexualizing substance in B. brunnea become responsible fo...
