Discovery of a novel class of potent HCV NS4B inhibitors: SAR studies on piperazinone derivatives

HTS screening identified compound 2a (piperazinone derivative) as a low micromolar HCV genotype 1 (GT-1) inhibitor. Resistance mapping studies suggested that this piperazinone chemotype targets the HCV nonstructural protein NS4B. Extensive SAR studies were performed around 2a and the amide function and the C-3/C-6 cis stereochemistry of the piperazinone core were essential for HCV activity. A 10-fold increase in GT-1 potency was observed when the chiral phenylcyclopropyl amide side chain of 2a was replaced with p- fluorophenylisoxazole-carbonyl moiety (67). Replacing the C-6 nonpolar hydrophobic moiety of 67 with a phenyl moiety (95) did not diminish the GT-1 potency. A heterocyclic thiophene moiety (103) and an isoxazole moiety (108) were incorporated as isosteric replacements for the C-6 phenyl moiety (95), resulting in significant improvement in GT-1b and 1a potency. However, the piperazonone class of compounds lacks GT-2 activity and, consequently, were not pursued further into development.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.33282-16-5,5-(4-Methoxyphenyl)isoxazole-3-carboxylic acid,as a common compound, the synthetic route is as follows.

General procedure: To a solution of oximic acid (4a-k, 3.6 mmol in 50 mL THF) was added HOBt (3.6 mmol) in an ice-cooled bath. Next, a mixture of cystamine dihydrochloride (1.8 mmol) and TEA (1 mL) in DMSO (6 mL) were added, followed by the addition of EDCI (4.0 mmol). After stirring for 24 h at room temperature, the reaction was quenched with water and extracted with EtOAc (60 mL ¡Á 3). The combined organic extracts were washed with brine (50 mL), dried over MgSO4 and then evaporated. The resulting residue was then purified by column chromatography on silica gel as indicated.
