title: Agelasines H and I, 9-methyladenine-containing diterpenoids from an Agelas sponge.
abstract: Two new diterpenes possessing a 9-methyladeninium substituent, agelasines H (5) and I (6), along with five related known ones, 1-4 and 7, were isolated from a sponge, Agelas sp. The structures of the new compounds were determined from spectral data. Compounds 2-4, 6, and 7 exhibited varying degrees of antimicrobial activity.
