8-chloroadenosine (8-Cl-Ado) is a ribonucleoside analog. The mechanism of its action remains poorly understood, however, it is known that the drug inhibits RNA synthesis. It has significant cytotoxic activity against lymphoid and myeloid malignant cells. The nucleoside analog 8-Cl-Ado is phosphorylated into its cytotoxic triphosphate 8-Cl-ATP. The accumulation of the cytotoxic metabolite results in a parallel decrease of the ATP cellular pools. 8-Cl-Ado gets incorporated into RNA during transcription, hindering this process. In addition, this triphosphate inhibits ATP-dependent poly(A) tail synthesis, and, as a consequence, mRNA processing is inhibited, resulting in vitro cytotoxicity in several solid and hematological malignancies. This agent is currently in clinical trials for the treatment of chronic lymphocytic leukemia and acute myeloid leukemia.
