Cytotoxic Diterpenoid Pseudodimers from the Korean Sponge <i>Phorbas gukhulensis</i>
Four new cytotoxic diterpenoid pseudodimers
(<b>2</b>–<b>5</b>), along with a previously reported
one, gukulenin A (<b>1</b>), were isolated from the marine sponge <i>Phorbas gukhulensis</i> collected off the coast of Gagu-do,
Korea. These novel compounds,
designated gukulenins C–F (<b>2</b>–<b>5</b>), were determined by extensive spectroscopic analyses to be pseudodimers
of the gagunins, like gukulenin A. The termini of the tropolone-containing
side chains in gukulenins C–E (<b>2</b>–<b>4</b>) were found to have diverse modifications involving acetamides
or taurine, whereas gukulenin F (<b>5</b>) was formed from <b>1</b> by the ring-opening of a cyclic hemiketal. The relative
and absolute configurations were assigned by Murata’s and modified
Snatzke’s methods using a HETLOC experiment and a CD measurement
of a dimolybdenum complex, respectively. All of these compounds exhibited
significant cytotoxicity against the K562 and A549 cell lines
Penicillipyrones A and B, Meroterpenoids from a Marine-Derived <i>Penicillium</i> sp. Fungus
Penicillipyrones
A (<b>1</b>) and B (<b>2</b>), two novel meroterpenoids,
were isolated from the marine-derived fungus <i>Penicillium</i> sp. On the basis of the results of combined spectroscopic analyses,
these compounds were structurally elucidated to be sesquiterpene γ-pyrones
from a new skeletal class derived from a unique linkage pattern between
the drimane sesquiterpene and pyrone moieties. Compound <b>2</b> elicited significant induction of quinone reductase
Asperphenins A and B, Lipopeptidyl Benzophenones from a Marine-Derived <i>Aspergillus</i> sp. Fungus
Asperphenins A (<b>1</b>) and
B (<b>2</b>), novel diastereomeric
lipopeptidyl benzophenone metabolites, were isolated from a marine-derived <i>Aspergillus</i> sp. fungus. On the basis of the results of combined
spectroscopic analyses, the structures of these compounds were determined
to be linear assemblies of three motifs: a hydroxy fatty acid, a tripeptide,
and a trihydroxybenzophenone. The absolute configurations were assigned
using chemical modifications and electronic circular dichroism (ECD)
calculations. The novel compounds exhibited significant cytotoxicity
on diverse cancer cells
