产品介绍 Mithramycin A is an antibiotic DNA/RNA polymerase and DNA binding transcriptional inhibitor observed to facilitate TNF-α and Fas-ligand induced apoptosis. As a DNA binding transcriptional inhibitor, mithramycin A binds to GC rich sequences located in the minor groove of DNA and is noted to be reversible and Mg2+ dependent. Additionally reported to a block transcriptional activation of the SV40 promoter via competitive binding against Sp1 transcription factor to GC rich areas in the early promoter. Mithramycin A is noted to supress TNF-α induced expression of fractalkine (CX3CL1) mRNA in a dose-dependent manner and to act as an effective differentiation agent of HL60 promyelocytic leukemia cells
用途 A polymerase inhibitor that binds to GC rich sequences located in the minor groove of DNA;DNA binding fluorescent dye. Until 2000 it was used to reduce high levels of plasma calcium; Used as an antineoplastic agent
生化机理 Anticancer antibiotic. Inhibits transcription and protein synthesis. Binds to DNA in native chromatin. Substrate of Pgp in MDR phenotypes.
