title: Bromosceptrin, an alkaloid from the marine sponge Agelas conifera.
abstract: Six dimeric bromopyrrole alkaloids (1-6) were isolated from a Florida Keys specimen of Agelas conifera. One of the constituents was identified as a new bromopyrrole metabolite, bromosceptrin (1). The structure of 1 was established from MS spectrometry and 1D and 2D NMR spectrocopy.
