Abstract
We report here the bioassay-guided
isolation of a new 1-deoxysphingoid,
3-<i>epi</i>-xestoaminol C (<b>1</b>), isolated from
the New Zealand brown alga <i>Xiphophora chondrophylla</i>. This is the first report of a 1-deoxysphingoid from a brown alga.
We describe the isolation and full structure elucidation of this compound,
including its absolute configuration, along with its bioactivity against
mycobacteria and mammalian cell lines and preliminary mechanism of
action studies using yeast chemical genomics
