Two new antimicrobial fatty acid esters, penicilloitins A and B (1 and 2), along with α-cyclopiazonic acid (3), tryptamine (4) and indole-3-carbaldehyde (5), were isolated from mycelial extracts and the culture broth of a marine endophytic Penicillium species and their structures established by spectroscopic techniques including 1D (1H NMR and 13C NMR) and 2D NMR (COSY, multiplicity-edited HSQC, and HMBC) as well as HRESIMS. Of these compounds, 1, 3 and 4 displayed modest antimicrobial activity.
