The synthesis of a novel series of 1-carba-isoflavanones through the α-arylation of α-tetralones is described. Several of these compounds demonstrated potent activity and selectivity in-vitro against HCV replicon reporter cells. Compound 10 (LQB-314) exhibited the best profile being active and selective in both replicon reporter cells (IC50 1.8 μM, SI > 111 and IC50 4.3 μM, SI > 46 in Huh7/Rep-Feo1b

The enantioselectiveelectrophilicfluorination of α-aryl-tetralones is promoted by cinchonine/selectfluor combinations. This strategy allows a facile synthesis of the corresponding 2-fluoro-2-aryl-1-tetralones with excellent yields (up to >98%) and moderate to good enantioselectivity (up to74%).

in moderate to good yields. These compounds were evaluated for their in vitro anti-proliferative effects against human breast cancer and leukemia celllines with diverse profiles of drug resistance. The most promising compounds, 3b, 3c, 8a and 8c, were effective on both neoplastic models. 3b and 8a induced higher toxicity on multidrug resistant cells and were able to avoid efflux by ABCB1 and ABCC1

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.
