Y. Doi et al., NEW SESTERTERPENES WITH NERVE GROWTH-FACTOR SYNTHESIS-STIMULATING ACTIVITY FROM THE OKINAWAN MARINE SPONGE HYRTIOS SP, Chemical and Pharmaceutical Bulletin, 41(12), 1993, pp. 2190-2191
Two new pentacyclic sesterterpenes, 12-O-desacetylfuroscalarol (1) and
12-O-desacetylscalarin (2), which enhance nerve growth factor synthes
is, have been isolated from the Okinawan marine sponge Hyrtios sp. and
their structures elucidated on the basis of spectroscopic data.
