Abstract
Marine organisms have been received significant attention in various fields since they produce unique and novel chemical compounds. Especially, marine microbes are considered as a novel source for biologically and chemically active products. Although marine microorganisms have been studied for new and unusual compounds, lots of microorganisms and their secondary metabolites still remain undiscovered. The strain 1310CH-032 was isolated from a sponge collected in Chuuk island, Micronesia and identified as Penicillium citrinum. From this strain, three new compounds (1 – 3), together with three known compounds, a tetramic acid derivative (4), isocyclocitrinol (5) and sorbicillinoid (6), were isolated from the EtOAc extract of the culture broth (25L). Their structures were determined by using MS and 2D NMR analyses..
