Brominated metabolites from the marine red alga laurencia similis

Abstract

One new sesquiterpenoid, aristolan-1a-bromo-9β,10β -epoxide (1), and one new indole alkaloid, 2,5-dibromo-N-methylindole (2), along with six sesquiterpenes and indoles were identified from the marine red alga Laurencia similis. Their structures were established on the basis of spectroscopic methods. © 2010 Verlag der Zeitschrift für Naturforschung, Tübingen.
