A source of natural inhibitors of endo-(1 → 3)-β-D glucanases has been found — sponges of the family Halichondriidae. It has been shown that the inhibitors are sulfated steroids such as halistanol…
Steroid compounds of marine sponges. III. 24-Ethyl-25-methylcholesta-5,22-dien-3β-OL — A new marine sterol from the spongeHalichondria sp.
A new sterol — 24 ethyl-25-methylcholesta-5,22-dien-3β-ol — has been isolated by column chromatography on silica gel from extracts of the spongeHalichondria sp. Its structure has been established on…

This work isolated for the first time compound 1 from the new sponge species Latrunculia oparinae (Demospongiae, Poecilosclerida,Latrunculiidae) that was collected during an expedition of the SRS Academic Oparin near the shores of Kuril Islands.
A new nortriterpenoid from the deep-sea spongeSarcotragus spinulosus
A new nortriterpenoid from the deep-sea spongeSarcotragus spinulosus was isolated and characterized. The structure of geranylfarnesylacetone was assigned to the new compound on the basis of analysis…
Sterols from the toxin-containing far-east sponge Monanchora pulchra
It was shown earlier that toxin-containing marine invertebrates, in particular sponges (phylum Porifera) and sea cucumbers (phylum Echinodermata, class Holothurioidea), often contain unusual sterols…
