Penicibilaenes A (1) and B (2), two sesquiterpenes possessing a tricyclo­[,5]­dodecane skeleton, were characterized from Penicillium bilaiae MA-267, a fungus obtained from the rhizospheric soil of the mangrove plant Lumnitzera racemosa. The lack of some key COSY and NOESY correlations made the structure elucidation of compound 1 difficult, which was solved by a X-ray crystallographic study. Compounds 1 and 2 exhibited selective activity against the plant pathogenic fungus Colletotrichum gloeosporioides (MIC = 1.0 and 0.125 μg/mL, respectively).
