Chemical analysis of the secondary metabolites of the Caribbean sponge Plakortis simplex, a source of many bioactive compounds, showed the presence of the new metabolite simplexidine (4), belonging to the extremely rare class of 4-alkyl-pyridinium alkaloids. The structural characterization of this molecule, based on spectroscopic methods, is reported.

Glycolipids from Sponges. 6.1 Plakoside A and B, Two Unique Prenylated Glycosphingolipids with Immunosuppressive Activity from the Marine Sponge Plakortis simplex
TLDR
Plakosides are strongly immunosuppressive on activated T cells and proved to be useful natural models for an improved comprehension of the structural requirements for immunomodulating activity of glycosphingolipids.
Cellular localisation of secondary metabolites isolated from the Caribbean sponge Plakortis simplex
TLDR
Experimental evidence is provided that the glycolipids and hopanoids and possibly also the polyketide plakortin are produced by microbial symbionts rather than the sponge from which the metabolites were originally isolated.
