    Abstract: Asmarine A and B, novel cytotoxic diterpene-alkaloids, have been isolated from the sponge Raspailia sp. The structure of these compounds have been established on the basis of NMR data and confirmed by X-ray analysis. Also claimed are compounds (I) or (II), wherein R represents hydrogen or lower alkyl or lower alkanoyl; R represents hydrogen or lower alkyl; R is either an alkyl or a cycloalkyl group containing one or more isopreneunits, or a monoterpene or a sesquiterpene or a sesquiterpene or a diterpene group; R or R represent hydrogen or lower alkyl; R represents lower alkyl; X represents F or Cl or Br or (I).
