title: Two new benzoquinone derivatives and two new bisorbicillinoids were isolated from a marine-derived fungus Penicillium terrestre.
abstract: Four new compounds were isolated from a marine-derived fungus Penicillium terrestre, namely 2-(2', 3'-dihydrosorbyl)-3,6-dimethyl-5-hydroxy-1,4-benzoquinone (1), 3-acetonyl-2,6-dimethyl-5-hydroxy-1,4-benzoquinone (2), dihydrobisvertinolone (3), tetrahydrobisvertinolone (4). Their structures were established on the basis of spectroscopic methods. The absolute configurations of 3 and 4 were determined by their CD spectra. Their cytotoxic effects on P388 and A-549 cell lines were preliminarily examined by the MTT method.
