- Discovery of N-(4′-(indol-2-yl)phenyl)sulfonamides as novel inhibitors of HCV replication
A series of novel 2-phenylindole analogs were synthesized and evaluated for activity in subgenomic HCV replicon inhibition assays. Several compounds containing small alkyl sulfonamides on the phenyl ring exhibiting submicromolar EC50 values against the genotype 1b replicon were identified. Among these, compound 25d potently inhibited the 1b replicon (EC50 = 0.17 μM) with 147-fold selectivity with respect to cytotoxicity. Compound 25d was stable in the presence of human liver microsomes and had a good pharmacokinetic profile in rats with an IV half-life of 4.3 h and oral bioavailability (F) of 58%.

- Cyanation of indoles with benzyl cyanide as the cyanide anion surrogate
A copper-mediated direct cyanation of indoles with benzyl cyanide as the cyanide anion surrogate has been achieved. The cascade reaction furnished 3-cyanoindoles under mild reaction conditions in good to excellent yields with various functional groups tolerance.
