title: 5-Bromo-8-methoxy-1-methyl-beta-carboline, an alkaloid from the New Zealand marine bryozoan Pterocella vesiculosa.
abstract: A new alkaloid, 5-bromo-8-methoxy-1-methyl-beta-carboline (1), has been isolated from the New Zealand marine bryozoan Pterocella Vesiculosa. Structural elucidation was achieved through NMR spectroscopic and mass spectrometric analysis, and a single-crystal X-ray diffraction analysis of 1 was performed. The biological activity of 1 was assessed against P388 murine leukemia cells and three microorganisms and compared with that of a number of related beta-carboline alkaloids.
