Isolation and Characterization of the New Purine 1,3,7-Trimethylisoguanine from the New Zealand Ascidian Pseudodistoma cereum

The new purine 1,3,7-trimethylisoguanine (1) has been isolated from the ascidian Pseudodistoma cereum. The structure of 1 was elucidated by analysis of NMR spectroscopic and mass spectrometric data and by comparison with the regioisomeric purine 1,3,7-trimethylguanine (2).
