Bioorg Med Chem Lett. 2010 Aug 1;20(15):4569-72. doi: 10.1016/j.bmcl.2010.06.015. Epub 2010 Jun 8.

Abstract

Three new bromotyrosine alkaloids, ceratinadins A-C (1-3), were isolated from an Okinawan marine sponge Pseudoceratina sp. and the structures of 1-3 were elucidated on the basis of spectroscopic data. Ceratinadin A (1) was a novel bromotyrosine alkaloid possessing an N-imidazolyl-quinolinone moiety. Ceratinadins A (1) and B (2) showed antifungal activity.
