| peniciadametizine a, a dithiodiketopiperazine with a unique spiro[furan-2,7'-pyrazino[1,2-b][1,2]oxazine] skeleton, and a related analogue, peniciadametizine b, from the marine sponge-derived fungus penicillium adametzioides. | peniciadametizine a (1); a new dithiodiketopiperazine derivative possessing a unique spiro[furan-2,7'-pyrazino[1,2-b][1,2]oxazine] skeleton, together with a highly oxygenated new analogue, peniciadametizine b (2); as well as two known compounds, brasiliamide a (3); and viridicatumtoxin (4), were isolated and identified from penicillium adametzioides as-53, a fungus obtained from an unidentified marine sponge. the unambiguous assignment of the relative and absolute configuration for the spiro cen ... | 2015 | 26058014 |
| bisthiodiketopiperazines and acorane sesquiterpenes produced by the marine-derived fungus penicillium adametzioides as-53 on different culture media. | chemical investigation of the marine-sponge-derived fungus penicillium adametzioides as-53 resulted in the identification of two new bisthiodiketopiperazine derivatives, adametizines a (1) and b (2), from cultivation in a liquid potato-dextrose broth (pdb) culture medium, whereas two new acorane sesquiterpenes, adametacorenols a (3) and b (4), were isolated from a rice solid culture medium. the structures of these compounds were elucidated on the basis of spectroscopic analysis. the absolute con ... | 2015 | 26039736 |
| first report on isolation of penicillium adametzioides and purpureocillium lilacinum from decayed fruit of cheongsoo grapes in korea. | two species, penicillium adametzioides and purpureocillium lilacinum, were isolated from decayed grapes (cv. cheongsoo) in korea. each species was initially identified by phylogenetic analysis of a combined dataset of two genes. internal transcribed spacer (its) and β-tubulin (bt2) genes were used for identification of penicillium adametzioides, and its and partial translation elongation factor 1-α (tef) genes were used for identification of purpureocillium lilacinum. morphologically, they were ... | 2012 | 22783137 |
