Salaramides A and B; two alpha-oxoamides isolated from the marine sponge Hippospongia sp. (Porifera, Dictyoceratida)

Nat Prod Commun. 2010 Feb;5(2):259-60.

Abstract

Two novel alpha-oxoamides, salaramide A (1) and its homologue salaramide B (2), were isolated from the Madagascar marine sponge, Hippospongia sp., collected in Salary Bay, north of Tulear. The structures of 1 and 2 were elucidated by interpretation of mass spectra, 1D and 2D NMR spectra, and confirmed by chemical transformation.
