kolokosides a-d: triterpenoid glycosides from a hawaiian isolate of xylaria sp.	four new triterpenoid glycosides, kolokosides a-d (1-4), along with the known compound 19,20-epoxycytochalasin n, were isolated from cultures of a hawaiian wood-decay fungus (xylaria sp.). the structures and relative configurations of 1-4 were determined primarily by analysis of nmr data, and the absolute configuration of 1 was assigned by application of the exciton chirality method. compound 1 exhibited activity against gram-positive bacteria.	2007	17284074
hymenopsins a and b and a macrophorin analogue from a fungicolous hymenopsis sp.	hymenopsin a (1), hymenopsin b (2), and a new macrophorin analogue, 2',3'-epoxy-13-hydroxy-4'-oxomacrophorin a (3), have been isolated from a fungicolous isolate of hymenopsis sp. (myc-1703; nrrl 37638). the structures and relative configurations of these compounds were assigned on the basis of 2d nmr and ms data, and the identity of 1 was confirmed by x-ray crystallographic analysis. the absolute configuration of 2 was proposed on the basis of cd analysis using both empirical and computational ...	2010	19928955
cytotoxic, radical scavenging and antimicrobial activities of sesquiterpenoids from the tahitian liverwort mastigophora diclados (brid.) nees (mastigophoraceae).	a drimane, (+)-drimenol (1), five known herbertanes, (-)-alpha-herbertenol (2), (-)-herbertenediol (3), mastigophorene a (4), (-)-mastigophorene c (5) and (-)-mastigophorene d (6), a pimarane, (-)-ent-pimara-8(14),15-dien-19-oic acid (7), and two eudesmanolides, (-)-diplophyllolide a (8) and (-)-diplophyllin (9) were isolated from the tahitian mastigophora diclados (brid.) nees. herbertane sesquiterpenes (2, 3, 5 and 6) showed cytotoxicity against hl-60 and kb cell lines, radical scavenging acti ...	2010	20458547
phomalevones a-c: dimeric and pseudodimeric polyketides from a fungicolous hawaiian isolate of phoma sp. (cucurbitariaceae).	phomalevones a-c (1-3), three new com-pounds with bis-dihydroxanthone and bis-benzophenone systems, were isolated from cultures of a hawaiian isolate of phoma sp. (myc-1734 = nrrl 39060; cucurbitariaceae). the structures of 1-3 were determined by analysis of nmr and ms data. the absolute configurations of the sp(3) stereocenters in the monomeric unit of 1 were assigned by application of mosher's method, and overall absolute configurations were proposed on the basis of ecd data using both computa ...	2011	21247198
