spectrum of biological activity against some cancers and DNA/RNA viruses as a promising inhibitor of the S-adenosyl-L-homocysteine (SAH) hydrolase and the enhancer of zeste homolog 2 (EZH2). Recently, 3-halogenated DZNep analogs were reported as potent inhibitors against RNA viruses as an inhibitor of SAH hydrolase, but 6-halogenated DZNep and its analogs was not studied as an antiviral agent to date
