Epothilone A (Epo A) is a biologically active macrolide produced from the fermentation of the soil bacteria S. cellulosum that was discovered as a potent antimicrotubule agent.{26908,19711,19714} In competition assays, epo A binds to β-tubulin with a similar order of magnitude as the binding of paclitaxel (Item No. 10461) to β-tubulin (IC50s = 2.3 and 3.6 µM, respectively).{26908,19711,19714,19713} Epo A is cytotoxic to human T-24 bladder carcinoma cells (IC50 = 0.05 µM in vitro) but has poor pharmacological properties and is 2-fold less potent in stabilizing microtubules compared to epothilone B (Item No. 10924).{26908}

  • 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}

    CAY10512 – 10 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}
