Abstract

Bioassay-guided fractionation of the EtOAc extract of the Palauan sponge Axinyssa aplysinoides yielded two novel alkaloids, 1 and 2. The structure of 2-(formylamino)trachyopsane (1) was determined by X-ray analysis; and the structure of N-phenethyl-N'-2-trachyopsanylurea (2), by interpretation of the spectral data.
