K. Yamada et al., BIOACTIVE TERPENOIDS FROM OCTOCORALLIA .4. 3 NEW CEMBRANE-TYPE DITERPENOIDS FROM THE SOFT CORAL LOBOPHYTUM-SCHOEDEI, Journal of natural products, 60(8), 1997, pp. 798-801
Three new cembrane-type diterpenoids, lobophynins A (1), B (2), and C
(3), were isolated from the soft coral Lobophytum schoedei. Their stru
ctures and relative stereochemistries were determined by extensive 2D
NMR studies. Lobophynin C (3) has ichthyotoxicity against the mosquito
fish, Oryzias latipes, and lethal activity toward brine shrimps.
