Title
The shape of vacuole and F-actin in tobacco BY-2 cells treated with neopetromin, a newly found peptide
Description
HPLC-MS analysis revealed the presence of an
unreported peptide in the extract of the marine sponge Neopetrosia
sp. Its structure was determined as a tripeptide, named
neopetromin (1), composed of two tyrosine and one tryptophan
residues with a heteroaromatic C−N cross-link between side
chains. The absolute configuration of amino acids was determined
using Marfey’s method after ozonolysis and hydrolysis of 1.
Compound 1 promoted vacuole fragmentation in an actin-
independent manner in tobacco BY-2 cells.
