Naruse N, Goto M, Watanabe Y, Terasawa T, Dobashi K: K1115 A, a new anthraquinone that inhibits the binding of activator protein-1 (AP-1) to its recognition sites. J Antibiot. 1998 Jun;51(6):545-52. II. Taxonomy, fermentation, isolation, physico-chemical properties and structure determination.. A new inhibitor of the action of activator protein-1 (AP-1), designated K1115 A, was isolated from the fermentation broth of an actinomycete strain Mer-K1115. K1115 A was determined to be a new anthraquinone, 3,8-dihydroxy-1-propylanthraquinone-2-carboxylic acid, based on spectroscopic analysis, derivatization experiments and biosynthetic studies with 13C-enriched acetic acid. Two co-produced compounds, K1115 B1 and B2, were also isolated and characterized as new members of the naphthopyranomycin and exfoliamycin group. |
