St. Laurent, Denis R. published the artcileHCV NS5A Replication Complex Inhibitors. Part 4. Optimization for Genotype 1a Replicon Inhibitory Activity, Safety of 1,5-Dichloroisoquinoline, the main research area is stilbene acylprolinamide preparation inhibition NS5A replication complex hepatitis C; structure bisacylprolinamide inhibition selectivity hepatitis C toxicity; hepatitis C genotype 1a replication inhibition stilbene acylprolinamide.
Sym. stilbene bis(acylprolinamides) such as I (R = PhCH2, 2-EtC6H4, Ph, 2-vinylphenyl, 1-naphthyl, 3-ethyl-2-pyridinyl, 4-ethyl-2-pyridinyl, 3-vinyl-2-pyridinyl, 3-phenyl-2-pyridinyl, 1-isoquinolyl, 3-isoquinolinyl, 2-quinolinyl, 4-isoquinolinyl, 4-quinazolinyl, 1-phthalazinyl, 3-chloro-1-isoquinolinyl, 4-chloro-1-isoquinolinyl, 5-chloro-1-isoquinolinyl, 6-chloro-1-isoquinolinyl, 7-chloro-1-isoquinolinyl, 3-fluoro-1-isoquinolinyl, 5-fluoro-1-isoquinolinyl, 3-methyl-1-isoquinolinyl, 5-methyl-1-isoquinolinyl, 3-methoxy-5-isoquinolinyl, 5-methoxy-1-isoquinolinyl, 3-chloro-1-naphthyl, 3-chloro-5-fluoro-1-isoquinolinyl, 3-chloro-5-methoxy-1-isoquinolinyl, 5-methoxy-2-quinolinyl, 7-methoxy-2-quinolinyl) derived from the library-synthesized lead I (R = PhCH2) were prepared as HCV genotype 1a (G-1a) and genotype 1b (G-1b) replicon inhibitors; their selectivities for inhibition of HCV over general viral inhibition and their cytotoxicities to human Huh-7 cells were determined The structure-activity relationships for inhibition of HCV replication by sym. bis(prolinamide) HCV inhibitors were determined I (R = 1-isoquinolinyl) was a selective HCV NS5A inhibitor exhibiting submicromolar potency against both G-1a and G-1b replicons; further optimization identified I (R = 3-chloro-5-methoxy-1-isoquinolinyl) as a potent, dual G-1a/1b HCV NS5A inhibitor. The structure-activity relations derived from I were used in the discovery of the NS5A replication complex inhibitor daclatasvir II.
