ABSTRACT
A new lignan, sonneralignan A (1), along with two known lignan compounds, (+)-lariciresinol-9-O-ß-D-glucopyranoside (2) and (-)isolariciresinol-9-O-ß-D-glucopyranoside (3) were isolated from the n-butanol extract of the mangrove Sonneratia apetala fruit. The structures of the compounds were elucidated on the basis of extensive spectral analysis. The evaluation of activity showed that compound 1 exhibited significant anti-aging activity, which extended the mean lifespan of Caenorhabditis elegans by up to 19.13% (p < 0.05) and 55.29% (p < 0.01) under normal and heat stress cultivation conditions, respectively. Molecular docking studies showed that compound 1 was bound to the DNA binding domain of DAF-16 and promoted the conformation of DAF-16, thus strengthening the interaction between the DAF-16 and related DNA. TRP-252, SER-250 and SER-249 of the binding region might be the key amino residues during the interaction.
