The synthesis of a series of 5-carba-pterocarpens derivatives involving the cyclization of alpha-aryl-alpha-tetralones is described. Several compounds demonstrated potent activity and selectivity in vitro against HCV replicon reporter cells. The best profile in Huh7/Rep-Feolb replicon reporter cells was observed with 2h (EC50 = 5.5 mu M/SI = 20), while 2e was the most active in Huh7.5-FGR-JC1-Rluc2A replicon reporter cells (EC50 = 1.5 mu M/SI = 70). Hydroxy groups at A- and D-rings are essential for anti-HCV activity, and substitutions in the A-ring at positions 3 and 4 resulted in enhanced activity of the compounds.
