Product information "DRB"
DRB is a nucleoside analog that inhibits several carboxyl-terminal domain (CTD) kinases including casein kinase II (IC50 range of 4-10 µM), Cdk7 (IC50 = ~20 µM), Cdk8 (IC50 = ~20 µM), and Cdk9 (IC50 = 3 µM). Through inhibition of certain CTD kinases, DRB inhibits an elongation step during RNA polymerase II transcription, which can trigger p53-dependent apoptosis of human colon adenocarcinoma cells without inducing genotoxic stress to healthy cells. DRB can also inhibit HIV transcription (IC50 = ~4 µM) by targeting elongation enhanced by the HIV-encoded transactivator Tat. Formal Name: 5,6-dichloro-1-beta-D-ribofuranosyl-1H-benzimidazole.
