Product Description
Diastereomeric lignan with cytoprotective and antioxidant activities in cultured hepatocytes. Inhibitor of LPS-inducible iNOS (NOS II), TNF-α and COX-2 expression in macrophages through suppression of IκBα phosphorylation and p65 nuclear translocation and of C/EBP and/or AP-1 activation, which may have constitutive anti-inflammatory effects. Suppressor of NF-κB by inhibiting transactivation activity of the RelA subunit. Inhibits staurosporine (Prod. No. ALX-380-014)-induced apoptosis. Inhibits RANKL-induced osteoclastogenesis by reducing ROS generation.
