✦ Synopsis

A new tetracyclic diamine, (-) halicyclamine B (1). has been isolated from the sponge Xesrospongia sp. and its structure was elucidated from NMR and X-ray crystallography data. Some biogenetic relationships are proposed between 1 and other polycyclic diamines recently reported from sponges.

New 26, 27-cyclosterols, aragusterols E-H, were isolated from the Okinawan marine sponge of the genus Xestospongia. Their structures were determined by spectroscopic measurement and chemical conversion. The absolute configurations of xestokerols A and B were determined by chemical conversion.
