Twenty-four compounds including eight steroids (1–8), nine triterpenoids (9–16, 24), three
flavonoids (20–22), and four benzenecarboxylic derivatives (17–19, 23) were isolated and …

Recent advances in sampling and novel techniques in drug synthesis and isolation have
promoted the discovery of anticancer agents from marine organisms to combat this major …

The stereochemistries of macrolactins B (1) and F (2), which are two of a series of six 24-
membered cyclic lactones from a taxonomically undefined deep-sea bacterium (C-237), 24 …

Erinarols G–J and 10 known ergostane-type sterols were isolated from a methanol extract of
the dried fruiting bodies of Hericium erinaceum. Their chemical structures were elucidated …

Phytochemical investigation of the hexane and CH 2 Cl 2 extracts of Erythrina stricta roots
and E. subumbrans stems led to the isolation of six pterocarpans, one flavanone, one …

Activity-directed isolation of the ethyl acetate, methylene chloride and n-hexane fractions of
Gloiopeltis furcata resulted in the isolation of 18 compounds. Their structures were …

Marine bryozoans play an important role for the discovery of novel bioactive compounds
among marine organisms. In this review, we summarize 164 new secondary metabolites …
