Novel pteridine alkaloids from the sponge Clathria sp.

Three novel pteridine alkaloids, pseudoanchynazines A-C (1-3) have been isolated from the sponge Clathria sp. collected by trawling (-100m) in a commercial clam fishery near the coasts of Rio Negro, Argentina, and their structures determined by a combination of chemical and spectroscopic techniques,...
