Glanvillic acids A and B and methyl capucinoate A, new metabolites isolated from the Caribbean sponges Plakortis halichondrioides and Plakinastrella onkodes
De. Williams et al., Glanvillic acids A and B and methyl capucinoate A, new metabolites isolated from the Caribbean sponges Plakortis halichondrioides and Plakinastrella onkodes, J NAT PROD, 64(3), 2001, pp. 281-285
Glanvillic acids A (2) and B (3) and the cytotoxic cyclic peroxides methyl
capucinoate A (4) and 5 were isolated from the Dominican marine sponges Pla
kortis halichondrioides and Plakinastrella onkodes, respectively. The struc
tures have been elucidated by spectroscopic analysis of 4 and 5 and of meth
yl glanvillates A (6) and B (7).
