Biological Activity of DL-Syringaresinol
| Description | 1. (+)-Syringaresinol shows inhibitory activity of Helicobacter pylori motility with the IC50 value is 50 microg/ml. 2. (-)-Syringaresinol has been reported to potently inhibit the proliferation of human promyelocytic HL-60 cells through G 1 arrest and induction of apoptosis, suggests that it may be a potential chemotherapeutic agent for the treatment of cancer. 3. Syringaresinol induces vasorelaxation by enhancing NO production in endothelial cells via two distinct mechanisms, phosphatidylinositol 3-kinase/Akt- and (PLC)/Ca2+/CaMKKβ -dependent eNOS phosphorylation and Ca(2+)-dependent eNOS dimerization. 4. Syringaresinol can protect against hypoxia/reoxygenation-induced cardiomyocytes injury and death by destabilization of HIF-1α in a FOXO3-dependent mechanism. |

References on DL-Syringaresinol
Inhibition of Helicobacter pylori motility by (+)-Syringaresinol from unripe Japanese apricot.[Pubmed:16394533]
Biol Pharm Bull. 2006 Jan;29(1):172-3.
A methanol extract from unripe Japanese apricot showed inhibitory activity of Helicobacter pylori motility. Inhibitory compound 1 was isolated and identified as (+)-syringaresinol (1) by spectoroscopic means. (+)-Syringaresinol (1) inhibited >90% of the H. pylori motility at a concentration of 500 microg/ml and the IC50 value was 50 microg/ml.
(-)-Syringaresinol inhibits proliferation of human promyelocytic HL-60 leukemia cells via G1 arrest and apoptosis.[Pubmed:18486907]
Int Immunopharmacol. 2008 Jul;8(7):967-73.
We examined the effect of (-)-syringaresinol, a furofuran-type lignan isolated from Daphne genkwa, on cell cycle regulation in HL-60 human promyelocytic leukemia cells in vitro. (-)-Syringaresinol decreased the viability of HL-60 cells by inducing G(1) arrest followed by apoptosis in a dose- and time-dependent manner. The G(0)/G(1) phase of the cell cycle is regulated by cyclin-dependent kinases (Cdk), cyclins and cyclin-dependent kinase inhibitors (Cdki). We show by western blot analysis, that the (-)-syringaresinol-induced G(1) arrest was mediated through the increased expression of Cdki proteins (p21(cip1/waf1) and p27(kip1)) with a simultaneous decrease in cdk2, cdk4, cdk6, cyclin D(1), cyclin D(2), and cyclin E expression. The induction of apoptosis after treatment with (-)-syringaresinol for 24 h was demonstrated by morphological changes, DNA fragmentation, altered ratio of Bax/Bcl-2, cleavage of poly(ADP-ribose) polymerase and flow cytometry analysis. (-)-Syringaresinol also induced cytochrome c release and activation of caspase-3 and caspase-9. To our knowledge, this is the first time that (-)-syringaresinol has been reported to potently inhibit the proliferation of human promyelocytic HL-60 cells through G(1) arrest and induction of apoptosis. These findings suggest that (-)-syringaresinol may be a potential chemotherapeutic agent for the treatment of cancer.
