  • Polysaccharide fractions isolated from Lentinula edodes fruitbodies and mycelium demonstrate strong immunomodulating, antioxidant and anticancer activity. We hypothesized, that polysaccharide fractions enriched in selenium would possess higher biological activity than non-enriched fractions, currently used to treat cancer. The first goal of this study was to isolate selenium (Se)-enriched polysaccharide fractions of different molecular weight from L. edodes mycelium cultivated under the submerged conditions in Se-enriched medium, and to investigate their monosaccharide composition....

  • During the last decades, dozens of compounds have been isolated from Mallotus apelta. These compounds which are classified under the categories viz. terpenoids, steroids, flavonoids, cumarino-lignoids, cembrane diterpenoids, and benzopyranoids. They were known to exhibit interesting biological activities. The phytochemical investigations revealed that malloapelta B which was the major component of M. apelta, showed strong NF-B and NFAT transcription factor inhibitory and cytotoxic activities. Numerous studies on the synthesis of some derivatives of malloapelta B were carried out.
