  • Spongicola tropicanus, a new genus and species of the family Eunicicolidae, and Asterocheres brevisurculus, a new species of the family Asterocheridae, are described as copepods associated with the sponge Phyllospongia foliascens (Pallas) from the Moluccas. Spongicola is the second genus of the family and may be characterized by a two-segmented prosome, the absence of leg 3, and the presence of leg 5. Asterocheres brevisurculus may be charecterized by one-segmented mandibular palp, short oral siphon, and 19-segmented female antennule.

  • The galactolipid M-5, which showed anti-inflammatory activity is glycoglycerolipid isolated from the Okinawa marine sponge Phyllospongia foliascens. Glycolipids have been synthesized by various methods, especially it were generally known that synthetic method of M-5 analogue and synthetic method of various glycolipids by glycosidation after synthesis of glycerolipid part. The others, it was not suggested that synthetic method via glycosylglycerol obtained by degradation from diglycoside. This study was carried out to investigate the synthesis of galactosylglycerol from melibiose as M-5 intermediate. Synthesis of galactosylglycerol was accomplished by selective protection of hydroxy group of sugar and diol cleavage by Pb(OAc)$_4$. As a result, galactosylglycerol was synthesized by 8 steps pathway and their structures were elucidated by analysis instrument.
