Astroides calycularis

The northeast Pacific bryozoans Phidolopora pacifica contained two nitrophenols, desmethylphidolopin (448) and 3-nitro-4-hydroxybenzyl alcohol (449) (365). Desmethylphidolopin (448) showed antimicrobial activity. 2-Amino-6-[(r/ ,2 5)-l, 2 -dihydroxypropyl]-3-methyl pterin-4-one (450) was isolated from the anthozoan Astroides calycularis collected in the Bay of Naples and exhibited cell growth-inhibiting activity (366). The structure of leucettidine, a pteridine derivative found in Leucetta microra-...
