ABSTRACT
The MeOH extract of an Indonesia Eudistoma sp. ascidian contained 1,3,O(7)-trimethylisoxanthopterin (1), a novel pteridine. The purification of 1 was achieved through flash C(18) chromatography and cyano HPLC. The structure was determined primarily through the use of (1)H-(13)C and (1)H-(15)N HMBC measurements and comparison with data obtained for 1,3,7-trimethylguanine (2).
