The review focuses on sulfated steroids that have been isolated from seaweeds, marine
sponges, soft corals, ascidians, starfish, and other marine invertebrates. Sulfur-containing …

Heteroatom steroids, a diverse class of organic compounds, have attracted significant
attention in the field of medicinal chemistry and drug discovery. The biological profiles of …

The present review describes the distribution and biological activities of natural mono-, di-,
and triaromatic steroids. It is shown that the producers of aromatic steroids are …

Polycyclic endoperoxides are rare natural metabolites found and isolated in plants, fungi,
and marine invertebrates. The purpose of this review is a comparative analysis of the …

Hydroperoxides (R-OOH) represent a small family of natural metabolites that have been
isolated from higher plants, fungi, and marine organisms. This paper is devoted to the …
