The present invention relates to small-molecule compounds that modulate capsid assembly and block hepatitis B virus (HBV) replication with the potential to be used as a monotherapy or in combination with other antivirals for the treatment of chronic HBV infection.
HBV is a small enveloped DNA virus belonging to the Hepadnaviridae family that is distributed worldwide as ten geographically distinct genotypes. Infection with HBV is typically self-limiting in otherwise healthy adults; however, vertical transmission or exposure during early childhood often results in a chronic lifelong infection. Worldwide there are an estimated >400 million individuals chronically infected with HBV that are at risk for complications due to liver disease, including cirrhosis, fibrosis, hepatocellular carcinoma and death. Each year 500,000 to 1 million people die from end stage liver disease as a consequence of HBV infection
The compact HBV genome utilizes four overlapping reading frames to encode the major structural and non-structural proteins: polymerase (F), envelope (S), core (C) and the X protein (X). HBV enters human hepatocytes via receptor mediated endocytosis, following binding of the envelope glycoprotein to its primary receptor, the bile acid transporter sodium taurocholate co-transporting polypeptide (NTCP). Following fusion with the endosome membrane, the capsid is ejected into the cytoplasm and translocated to the nucleus. The partially double-stranded, relaxed, circular HBV genome (RC DNA) is converted to a covalently closed circular DNA form (cccDNA) by host cellular DNA repair mechanisms. The HBV cccDNA serves as the template for RNA polymerase II-dependent transcription of multiple RNA species, including viral mRNAs and the 3.2-kbp pre-genomic RNA (pgRNA). During the maturation process, pgRNA is packaged into capsids along with the HBV polymerase. The pgRNA is then reverse transcribed into a negative-stranded DNA template that is subsequently converted into the partially double-stranded RC DNA species by the polymerase. Mature, enveloped HBV particles containing the RC DNA genome are secreted from the surface of the infected hepatocyte ready to initiate new cycles of infection.
The capsid is composed of 240 copies of the core protein that spontaneously self-assemble through a network of weak inter-subunit interactions. In vitro evidence suggests that a timer of core dimers initiates the nucleation event that rapidly recruits additional dimers to form the icosahedral core structure (T=4). In addition to its structural role, encapsidation of the pgRNA is an essential step required for HBV DNA synthesis and formation of the mature capsid particle. The core protein also plays an important role in shuttling the RC DNA into the nucleus to initiate and maintain the cccDNA pools and may also play a role in regulating interferon sensitive gene expression. Thus, capsid modulators may have the unique ability to intervene at multiple points in the HBV lifecycle.
Several chemotype series of HBV capsid assembly modulators have been reported in the literature including: phenylpropenamides (PP) (e.g., AT-130), heteroarylpyrimidines (HAP) (e.g. Bay 41-4109), and sulfamoylbenzamides (SBA) (e.g. NVR 3-778). Capsid modulators exert their effects on the assembly process through one of two different mechanisms of action. The HAP series induces the aberrant assembly of large capsid aggregates that subsequently triggers the degradation of the core protein. The PP and SBA series, on the other hand, appear to accelerate capsid assembly resulting in the production of authentic empty capsid particles that have failed to incorporate pgRNA. Assembly modulators representing both mechanisms have demonstrated the ability to reduce HBV DNA levels in mouse models of infection. More recently, NVR 3-778 (SBA) demonstrated clinical proof-of-concept in a Phase 1b clinical trial, resulting in a −1.7 log 10 reduction in HBV DNA following 600 mg bid dosing for 29 days.
Described herein are compounds of Formula (I), (Ia)-(Id) that modulate the normal capsid assembly of hepatitis B core proteins to inhibit the hepatitis B lifecycle, and thus act as antiviral agents toward HBV.

Chronic hepatitis B infection (CHB) is currently managed with interferon-alpha or nucleoside(tide) analog-based therapies that target the HBV encoded polymerase/reverse transcriptase. The effectiveness of interferon-alpha is limited by inadequate long term responses and severe side effects, while entecavir and tenofovir, are generally well-tolerated, possess a high barrier to resistance and potently suppress viral replication. None of the aforementioned frontline therapies are curative, however, and expensive lifelong therapy is required to maintain a virologic response and prevent the complications associated with liver disease. Novel therapies representing different treatment classes are therefore urgently required to improve functional cure rates (i.e. defined as the loss of HBsAg expression) and shorten treatment durations. Modulators of HBV capsid assembly represent one such class of antivirals with the potential to improve outcomes for chronically infected individuals.

The term “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined above. Further, an optionally substituted group may be un-substituted (e.g., —CH2CH3), fully substituted (e.g., —CF2CF3), mono-substituted (e.g., —CH2CH2F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., —CH2CHF2, —CH2CF3, —CF2CH3, —CFHCHF2, etc.). It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (e.g., substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum) that are sterically impractical and/or synthetically non-feasible.

The anti-HBV activity of the Capsid Assembly Modulators (CAMs) was evaluated in a cell based assay utilizing the human hepatoma cell line HepAD38 (Ladner, S K., et al., 1998). HepAD38 cells were derived from the parental line, HepG2, that were stably transfected with a construct containing an HBV genome (genotype D, serotype ayw) under the control of a tetracycline repressible CMV promoter. Upon removal of tetracycline, viral pre-genomic RNA (pgRNA) and mRNAs are expressed and infectious viral particles are assembled and secreted into the culture medium providing a reliable, robust system to measure multiple steps of the HBV life cycle. Disruption of capsid formation results in reduced levels of DNA-containing virus particles that are released into the culture supernatant. To quantify the effect of CAMs on HBV replication, we developed a sensitive QPCR-based assay that measures extracellular HBV DNA levels upon treatment of HepAD38 cells with various concentrations of test compounds.
HepAD38 cells were maintained in DMEM/F12 medium containing 10% FBS, 400 μg/mL G418 and 0.3 μg/mL tetracycline (tet+ media) to maintain repression of HBV replication. To evaluate each compound, HepAD38 cells were seeded into 24-well collagen coated culture plates (Corning BioCoat) at a density of 200,000 cells per well in 1 mL of medium without tetracycline (tet-media) and allowed to adhere overnight at 37° C., 5% CO2 in a humidified incubator. The following day, media was refreshed and a dose range of each compound was prepared by performing 1 log10 serial dilutions in 100% DMSO at 200× the desired assay concentration. Dilutions were then added to the cells resulting in a final dose range of 1 μM to 10 pM and the plates were returned to the incubator. Following 7 days of incubation, culture supernatants were harvested and HBV DNA levels were evaluated by QPCR and compared to the vehicle treated control wells (i.e. DMSO alone).
To quantify HBV DNA levels, cell culture supernatants were diluted 1:10 in sterile, nuclease-free water (Gibco). The diluted supernatants were subsequently added to a PCR master mix containing 1× Roche Light Cycler Master Mix, 0.5 μM forward primer, 0.5 μM reverse primer (Fwd: 5′-TTGGTGTCTTTCGGAGTGTG (SEQ ID NO 1); Rev: 5′-AGGGGCATTTGGTGGTCTAT (SEQ ID NO 2)), 0.2 μM Roche Universal Probe Library Probe 25. The volume was brought to 20 μL with nuclease-free water and amplification of the HBV target sequence was performed using a Roche LightCycler 480 QPCR instrument. PCR extended out to 45 cycles with each cycle consisting of a denaturation step at 95° C. for 10 sec., followed by an annealing step at 60° C. for 10 sec. and a brief extension step at 72° C. for 1 sec.
Extracellular HBV DNA levels, expressed in copies/mL, were determined by comparison to a standard curve (102-109 copies/mL) using the Roche LightCycler analysis software. These values were subsequently converted to percent inhibition of HBV replication by dividing the HBV DNA levels in the experimental samples with those obtained from the vehicle control (˜1-2×105 copies/mL). Potency, expressed as an EC50 (the effective concentration required to inhibit 50% of HBV replication), was calculated from the dose-response curve using a 4-parameter non-linear regression analysis (GraphPad Prism). The nucleoside analog inhibitor entecavir was used as a positive control to validate each assay run. The EC50 value of entecavir in the HepAD38 assay was 0.5 nM, as previously reported in the literature.
Table 2 summarizes the antiviral activity of the exemplary compounds. A: EC50>1 μM; B: EC50 values between 0.5 μM and 1 μM, inclusive; C: EC50 values between 0.05 μM and 0.499 μM, inclusive; D: EC50 values <0.05 μM. NT=not tested. NA=not available.
To evaluate antiviral selectivity, the cytotoxic activity of each compound was determined using a standard cell viability assay performed on the parental HepG2 cell line. Cell viability was determined by measuring the conversion of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) to the insoluble formazan salt crystal that occurs in live cells. Briefly, HepG2 cells were seeded in 96-well plates at a density of 20,000 cells per well in EMEM+10% FBS (complete growth medium) and allowed to adhere overnight in a 37° C., 5% CO2 humidified incubator. The next day, test agents were prepared by performing 8 half-log10 serial dilutions in 100% DMSO at 200× the final desired concentration in the assay. Compounds were tested over a range of concentrations from 30 μM to 1.0 nM in the assay. HepG2 cells were incubated in the presence of various concentrations of CAMs for 7 days in a 37° C., 5% CO2 humidified incubator. At the completion of the 7-day incubation period, MTT reagent was added to each well and the mixture was incubated for an additional 3-4 hours. At the completion of the incubation period, all wells were aspirated to remove the culture medium. The formazan crystals were solubilized from the cell monolayers with 100% DMSO. Plates were briefly mixed on an orbital shaker and absorbance was measured at 492 nm using a Perkin-Elmer EnVision multi-label plate reader. All absorbance values were converted to a percentage of the signal obtained from the vehicle treated controls. Absorbance values at 492 nm are directly proportional to the number of viable cells present in the sample. A CC50 value (cytotoxic concentration that results in loss of 50% cell viability) was calculated from the dose-response curve by 4-parameter, non-linear regression analysis using the GraphPad Prism software. The positive control compound, staurosporine, reduced the viability of HepG2 cells in a dose-dependent manner (CC50=100 nM).
Table 3 summarizes the cytotoxicity assay data in the hepatocyte cell line HepG2 for the example compounds. A: CC50>30 μM; B: CC50 values between 5 μM and 30 μM, inclusive; C: CC50 values between 0.5 μM and 4.99 μM, inclusive; D: CC50 values <0.5 μM. NT=not tested. NA=not available.
