Abstract

04, 2022) Abstract: Phytochemical investigation of Psammosilene tunicoides led to isolation of a new cyclicpeptide, psammosilenin C ( 1 ) and three known compounds, 1-O-( β -D-glucopyranosyl)-(2 S ,3 R ,4 E ,8 E )-2-[(2 R )-2-hydroxypentadecanoylamino]-4,8-octadecadiene-1,3-diol ( 2 ), dihydroferulic acid ( 3 ) and vanillylacetone ( 4 ). Their structures were elucidated by comprehensive spectroscopic methods, including 1D and 2D NMR spectroscopic, and HR-ESI-MS spectrometric data. Compounds 1 , 2 and 4 showed inhibitory activities on lipopolysaccharide (LPS)-induced NO release in RAW
