Abstract
Two new antimicrobial fatty acid esters, penicilloitins A and B (
and
), along with
-cyclopiazonic acid (
), tryptamine (
) and indole-3-carbaldehyde (
), were isolated from mycelial extracts and the culture broth of a marine endophytic
species and their structures established by spectroscopic techniques including 1D (
H NMR and
C NMR) and 2D NMR (COSY, multiplicity-edited HSQC, and HMBC) as well as HRESIMS. Of these compounds,
and
displayed modest antimicrobial activity.
