Cayman 3-Hydroxy Stearic Acid Methyl Ester; Purity- Greater Than

Chrysomycin B is an antibiotic isolated from a strain of Streptomyces. It differs from its analog chrysomycin A (Item No. )^, 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.^,, It also causes DNA damage in the human lung adenocarcinoma A549 cell line and inhibits topoisomerase II. 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.
