5,6-Dichlorobenzimidazole riboside is a nucleoside analog that inhibits several carboxyl-terminal domain (CTD) kinases including casein kinase II and CDKs[1][2][3][4]. 5,6-Dichlorobenzimidazole riboside trigger p53-dependent apoptosis of human colon adenocarcinoma cells without inducing genotoxic stress to healthy cells[5].
