Antibiotic. Inhibitor of HSP90. Interacts with the C-terminal ATP-binding domain of HSP90 in contrast to the benzoquinone ansamycins 17-AAG (Prod. No. BML-EI308), geldanamycin (Prod. No. BML-EI280), herbimycin A (Prod. No. BML-EI227) and the chemically unrelated radicicol (Prod. No. BML-EI285), which bind to the N-terminal ATP-binding site of HSP90. Inhibitor of DNA gyrase. Useful for the production of positively supercoiled plasma DNA, targeting the nucleotide-binding site of gyrase B. Inhibits retrovirus RNA-dependent DNA polymerase. Potent inhibitor of ADP ribosylation. Inhibits LPS-induced production of pro-inflammatory cytokines, such as TNF-α, IL-1, IL-6 and IL-10. Inhibits protein synthesis and alters the phosphorylation state of several cytosolic proteins. Reverses etoposide resistance in non-P-glycoprotein expressing multidrug resistant (MDR) tumor cell lines. Inducer of CD38 on cells of the myelomonocytic lineage. Forms ion channels in lipid bilayers. Inhibitor of breast cancer resistance protein (BCRP)
