Chrysomycin B is an antibiotic isolated from a strain of Streptomyces.{22201} It differs from its analog chrysomycin A (Item No. 14188){22203,22199} by having a methyl, rather than vinyl, group in the 8-position of the chromophore. Like its analog, chrysomycin B suppresses the growth of transplantable tumors in mice, an effect that may be related to its ability to bind DNA.{22199,22204,22198} It also causes DNA damage in the human lung adenocarcinoma A549 cell line and inhibits topoisomerase II.{22198} Chrysomycin B is structurally very similar to gilvocarcin V, which promotes DNA cross-linking with histone 3 and GRP78 when photoactivated by near-UV light.{22200}

    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.
