Four cyclohexanol analogues, dendrodochols A-D (1-4), were isolated from a Dendrodochium sp. fungus associated with the sea cucumber Holothuria nobilis Selenka collected from the South China Sea. The structures were elucidated by means of detailed spectroscopic analysis. The absolute configurations were assigned using a solution TDDFT/ECD calculation approach and the modified Mosher's method. In an in vitro bioassay, these compounds exhibited no growth inhibition activity against the A549 and MG63 cell lines. Dendrodochols 1 and 3 exhibited modest antifungal activity against Candida strains, Cryptococcus neoformans, and Trichophyton rubrum, whereas 2 and 4 showed no activity against the tested strains.

Dendrodolides A-M (1-13), 13 new 12-membered macrolides, were isolated from Dendrodochium sp., a fungus associated with the sea cucumber Holothuria nobilis Selenka, which was collected from the South China Sea. The structures of the dendrodolides were elucidated by means of detailed spectroscopic analysis and X-ray single-crystal diffraction.

The data of long-term investigations of the control of macrocyclic trichothecenes biosynthesis by means ofthe elements of mineral nutrition, microelements in particular in Dendrodochium toxicum Pidopl. et Bilai are presented. The media for providing the dominant synthesis (50-70 %) of certain component from the composite complex of dendrodochins and so for obtaining the fractions enriched with this component, have been worked out.

[structure: see text]. Integramides A and B are two novel 16-mer linear peptides rich in C(alpha)-methyl amino acids that were isolated from fungal extracts of Dendrodochium sp. by employing a bioassay-guided isolation procedure using recombinant HIV-1 integrase.

The dynamics of change in the component composition of dendrodochines in the process of cultivation of Dendrodochium toxicum 100115 has been studied. It has been shown on the basis of the data of thin-layer chromatography that verrucarines A and J are found during the whole period of the fungus growth. Rhoridines A and E in the initial period of cultivation (1-2 days) are found in trace quantities only.
