title: [Synthesis of S-9-(2,3-dihydroxypropyl)adenine (DHPA) analogs and their inhibition of S-adenosyl-L-homocysteine (SAH) hydrolase].
abstract: In order to search for new antiviral agents with high potency and low toxicity, eleven new acyclonucleosides were synthesized. Nucleic-acid bases were condensed with 3-chloro-2-methylpropene to give 5-8a. b, which were oxidized by N-methylmorpholine-N-oxide in the presence of OsO4 to give vicinal dihydroxy acyclonucleosides 1-4a.b. Four DHPA analogs have been tested for the inhibitory activities on s-adenosyl-L-homocysteine hydrolase (SAH). Only compound 1 showed some enzyme inhibitory effect with IC50 of 1.1 mmol.L-1.
