HCV NS5A replication complex inhibitors. Part 3: discovery of potent analogs with distinct core topologies
摘要:
In a recent disclosure,(1) we described the discovery of dimeric, prolinamide-based NS5A replication complex inhibitors exhibiting excellent potency towards an HCV genotype 1b replicon. That disclosure dealt with the SAR exploration of the peripheral region of our lead chemotype, and herein is described the SAR uncovered from a complementary effort that focused on the central core region. From this effort, the contribution of the core region to the overall topology of the pharmacophore, primarily vector orientation and planarity, was determined, with a set of analogs exhibiting < 10 nM EC50 in a genotype 1b replicon assay.

The present disclosure is generally directed to antiviral compounds, and more specifically directed to compounds which can inhibit the function of the NS5A protein encoded by Hepatitis C virus (HCV), compositions comprising such compounds, and methods for inhibiting the function of the NS5A protein.
A process for the preparation of imidazoles which are substituted with p-nitrophenyl in the 2- and/or 4- and/or 5-position and may carry additional substituents, by reacting imidazoles which are substituted by phenyl in the 2- and/or 4- and/or 5-position and may carry additional substituents with mixtures of sulfuric acid and nitric acid, wherein the reaction is carried out in the presence of urea.

Verfahren zur Herstellung von in 2- und/oder 4- und/oder 5-Position durch p-Nitrophenyl und gegebenenfalls zusätzlich substituierten Imidazolen durch Umsetzung von in 2- und/oder 4- und/oder 5-Position durch Phenyl und gegebenenfalls zusätzlich substituierten Imidazolen mit Gemischen von Schwefelsäure und Salpetersäure, indem man die Reaktion in Gegenwart von Harnstoff durchführt.
Overall 21 imidazole-based chromophores have been synthesized and fully characterized. The imidazole core was systematically substituted with donors (NMe(2) and OMe) and acceptors (NO(2) and CN groups) additionally separated from the imidazole by pi-spacers such as 1,4-phenylen, styryl or thiophen-2-yl in order to finely tune their intramolecular charge transition. The target chromophores were further investigated by UV/Vis spectroscopy as potentially NLO-active compounds.
