A. Aiello et al., Sulcatin, a novel antiproliferative N-methylpyridinium alkaloid from the ascidian Microcosmus vulgaris, J NAT PROD, 63(4), 2000, pp. 517-519
A new N-methylpyridinium alkaloid, with an interesting antiproliferative ac
tivity in vitro, has been isolated from the Mediterranean tunicate Microcos
mus vulgaris. Its structure has been elucidated by spectroscopic analysis,
including extensive 2D NMR experiments.
