Austalides V and W, new meroterpenoids from the fungus Aspergillus ustus and their antitumor activities.

Two new austalide meroterpenoids, named austalides V and W (1 and 2), were isolated from the fungus Aspergillus ustus VKM F-4692. Their structures were elucidated by extensive spectroscopic analysis and by comparison with related known compounds. The main structural feature of both compounds is a tetrahydrofuranyl ring (G), a structural fragment, first found in austalides.

Secondary metabolites of the genus Penicillium from undisturbed and anthropogenically altered Antarctic habitats.

From undisturbed Antarctic habitats (permafrost sediments 30-150 thousand years of age, water of Radok Lake) and superficial deposits contaminated with petroleum products, we isolated 14 and 9 strains of Penicillium fungi, respectively. Comparison of the fungal complexes showed them to differ by species composition; only two species-P. palitans and P.
