6-Chloropurine riboside is a nucleoside precursor.1 It has been used in the synthesis of adenosine derivatives with antiproliferative activity in human gastric cancer cells expressing the adenosine A3 receptor. 6-Chloropurine riboside has also been used in the synthesis of N6-benzyladenosine derivatives with antiproliferative activity in a variety of cancer cells or inhibitory activity against T. gondii replication in CRL-1634/Hs27 human skin fibroblasts.2,3
