17α-Estradiol is the natural optical isomer of 17β-estradiol (Item No. 10006315), the major estrogen secreted by the premenopausal ovary. 17α-Estradiol is a less active isomer than its counterpart, displaying 100-fold lower estrogenic activity relative to 17β-estradiol.{24968} It can inhibit 5α-reductase, which plays a role in regulating hair growth. 17α -estradiol is reported to activate the MAPK/ERK and PI3K-Akt signaling pathways via activation of the estrogen receptor-X and has been shown to be neuroprotective after an ischemic stroke and oxidative stress and in transgenic mice with Alzheimer’s disease.{24968,13837}

    CAY10512 – 500 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
