pubpic2010xxA small library of 2′,4′- and 3′,4′-bridged nucleoside analogues was synthesized and tested for antibacterial, antitumor, and antiviral activities, leading to the identification of one nucleoside that exhibited significant antiviral activity against pseudoviruses SF162 (IC50 = 7.0 μM) and HxB2 (IC50 = 2.4 μM). These findings render bridged nucleosides as credible leads for drug discovery in the anti-HIV area of research.
