Phyllospongia foliascens

A sulfated galactolipid, M-6 (607) was isolated from Phyllospongia foliascens. M-6 (607) consisted of an inseparable mixture of compounds with variations occurring in the carboxylic acid portion of the molecule. Compound 607 has resistant activity against complement fixation in serological reactions [484]. 

Schmitz and co-workers next published a pair of papers that dealt with the isolation and characterization of sesterterpenes from two different sponges. The first of these reports described the structural characterization of phyllofolactones C and D, minor homoscalarane sesterterpenes from the Chinese sponge Phyllospongia foliascens.117 The structure of phyllofolactone-C (54) is shown. The second report detailed the characterization of halisulfate-7 (55), a sesterterpene sulfate from a sponge, Coscinoderma sp.118... 

From the Neo Guinean sponge Phyllospongia foliascens, together with bishomoscalarane derivatives (see tetracyclic section), was isolated a related compound (252) with an additional cyclobutane ring. This...
