Lm. Nogle et al., Somamides A and B, two new depsipeptide analogues of dolastatin 13 from a Fijian cyanobacterial assemblage of Lyngbya majuscula and Schizothrix species, J NAT PROD, 64(6), 2001, pp. 716-719
Somamides A (1) and B (2) were isolated from assemblages of the marine cyan
obacteria Lyngbya majuscula and Schizothrix sp. from the Fijian Islands. Th
ese new depsipeptides are analogous in structure to the cyanobacterial meta
bolite symplostatin 2 (4) as well as dolastatin 13 (3), originally isolated
from Dolabella auricularia, further demonstrating the cyanobacterial origi
n of the dolastatins.
