Synthesis and In-vitro Activity of 4 '-Modified Analogues of ddA as Potent Anti-HIV Agents

Abstract

This paper reports the synthesis of novel 4'-hydrophobic pocket deoxythreosyl C-nucleosides. The key threose-like intermediates 9 and 14 were constructed from acyclic ketone derivatives, respectively. The antiviral activities of the synthesized compounds against the HIV-1, HSV-1, HSV-2, and HCMV viruses were evaluated. The 9-deaza-adenine derivatives 10 and 20 showed good anti-HIV activity without exhibiting significant cytotoxicity.
