ERβ Activator

Saikosaponin D is a triterpene saponin isolated from Bupleurum, with anti-inflammatory, anti-bacterial, anti-tumor, and anti-allergic activities; Saikosaponin D inhibits selectin, STAT3 and NF-kB and activates estrogen receptor-β.

Hydroxytyrosol acetate is an orally active, blood-brain barrier-permeable multi-active compound with multiple effects including antibacterial, antioxidant, anti-platelet aggregation, and neuroprotective activities. Hydroxytyrosol acetate not only inhibits the growth of Vibrio by increasing bacterial membrane permeability, but also interacts with DNA and mediates supercoiled DNA relaxation. Meanwhile, Hydroxytyrosol acetate effectively reduces thrombosis and inhibits lipid oxidation by inhibiting COX activity and promoting vascular nitric oxide production. In terms of neuroprotection, Hydroxytyrosol acetate significantly alleviates neuronal apoptosis and inflammatory responses by up-regulating the expression level of ERβ, thereby improving cognitive function in Alzheimer's disease models. Hydroxytyrosol acetate has been widely used in scientific research related to Vibrio infection, arterial thrombosis, Alzheimer's disease and other related fields.

(+)-Medicarpin, a pterocarpan, is a type of isoflavonoid isolated from several medicinal plant species with various biological effects, including Sophora japonica, Zollernia paraensis and Platymiscium yucatamun, Machaerium aristulatum, Platymiscium floribundum, and so on. (+)-Medicarpin potently inhibits osteoclastogenesis and promotes bone healing and increases bone mass by osteoblast differentiation with estrogen receptor (ER) β-mediated osteogenic action.
