RESUMO
A novel series of non-nucleoside HCV NS5B polymerase inhibitors was prepared from a (2Z)-2-benzoylamino-3-(4-phenoxy-phenyl)-acrylic acid template. Solution and solid phase analog synthesis focused on the northern region of the template combined with structure based design led to the discovery of several potent and orally bioavailable lead compounds.

A novel series of nonnucleoside HCV NS5B polymerase inhibitors were prepared from (2Z)-2-(benzoylamino)-3-(5-phenyl-2-furyl)acrylic acid, a high throughput screening lead. SAR studies combined with structure based drug design focusing on the southern heterobiaryl region of the template led to the synthesis of several potent and orally bioavailable lead compounds. X-ray crystallography studies were also performed to understand the interaction of these inhibitors with HCV NS5B polymerase.
