Molecular Formula: C29H28F4N4O4

Letermovir (INN) is an antiviral drug that is being developed for the treatment of cytomegalovirus (CVM) infections. It has been tested in CMV infected patients with allogeneic stem cell transplants and may also be useful for other patients with a compromised immune system such as those with organ transplants or HIV infections.[1]

The drug has been granted fast track status by the US Food and Drug Administration (FDA) and orphan drug status by the European Medicines Agency.[1]

The drug candidate is under development by Merck & Co., Inc as investigative compound MK-8828.[2]

AIC246, also known as letermovir, is a novel anti-CMV compound with IC50 value of 5.1 ± 1.2 nM. It targets the pUL56 (amino acid 230-370) subunit of the viral terminase complex [1].
The subunit pUL56 is a component of the terminase complex which is responsible for packaging unit length DNA into assembling virions.
AIC246 has a novel mode of action targets the enzyme UL56 terminase and keep active to other drug-resistant virus. The anti-HCMV activity of AIC246 was evaluated in vitro by using different HCMV laboratory strains, GCV-resistant viruses. The result showed that the inhibitory potentcy of AIC246 surpasses the current gold standard GCV by more than 400-fold with respect to EC50s (mean, ∼4.5 nM versus ∼2 μM) and by more than 2,000-fold with respect to EC90 values (mean, ∼6.1 nM versus ∼14.5 μM).  In the CPE-RA strains, the EC50 values of AIC 246 ranged from 1.8 nM to 6.1 nM [2].
In mouse model with HCMV subcutaneous xenograft, oral administration of AIC246 caused significant a dose-dependent reduction of the HCMV titer. 30 mg/kg/d AIC246 for 9 days induced PFU reduction with maximum efficiency, compared with the gold standard GCV at the ED50 and ED90 level [2].

Human cytomegalovirus (HCMV) remains the leading viral cause of birth defects and life-threatening disease in transplant recipients. All approved antiviral drugs target the viral DNA polymerase and are associated with severe toxicity issues and the emergence of drug resistance. Attempts to discover improved anti-HCMV drugs led to the identification of the small-molecular-weight compound AIC246 (Letermovir). AIC246 exhibits outstanding anti-HCMV activity in vitro and in vivo and currently is undergoing a clinical phase IIb trial. The initial mode-of-action studies suggested that the drug acts late in the HCMV replication cycle via a mechanism distinct from that of polymerase inhibitors. Here, we extend our mode-of-action analyses and report that AIC246 blocks viral replication without inhibiting the synthesis of progeny HCMV DNA or viral proteins. The genotyping of mutant viruses that escaped AIC246 inhibition uncovered distinct point mutations in the UL56 subunit of the viral terminase complex. Marker transfer analyses confirmed that these mutations were sufficient to mediate AIC246 resistance. The mapping of drug resistance to open reading frame UL56 suggests that viral DNA processing and/or packaging is targeted by AIC246. In line with this, we demonstrate that AIC246 affects the formation of proper unit-length genomes from viral DNA concatemers and interferes with virion maturation. However, since AIC246-resistant viruses do not exhibit cross-resistance to previously published terminase inhibitors, our data suggest that AIC246 interferes with HCMV DNA cleavage/packaging via a molecular mechanism that is distinct from that of other compound classes known to target the viral terminase.

2-methoxy-5-trifluoromethylphenyl isocyanate (274.3 g) are dissolved in acetonitrile (1 L), then 2-bromo-6-fluoroaniline (200 g) was added with acetonitrile (50 mL) flushed. The resulting clear solution is at 38 h reflux (ca. 85 0 stirred C), then under vacuum at 40 0 concentrated C a dogged mush. This is filtered off, with acetonitrile (260 mL, to 0-5 0 C cooled) washed and incubated overnight at 45 0 dried C in the VDO using entraining nitrogen. Thus, a total of 424.3 g of N- (2-bromo-6-fluorophenyl) -N ‘- get [2-methoxy-5- (trifluoromethyl) phenylJ-urea as a solid, corresponding to 99.2% of theory.

WO 2015088931

Human cytomegalovirus (HCMV) is ubiquitously distributed in the human population. In immunocompetent adults infections are mainly asymptomatic, but in

immunocompromised patients, such as transplant recipients or AIDS patients, life threatening infections occur at a high rate. HCMV is also the leading cause of birth defects among congenitally transmitted viral infections.

Various substituted heterocyclic compounds are inhibitors of the HCMV terminase enzyme. Included in these heterocycles are quinazolines related to Compound A, as defined and described below. These compounds and pharmaceutically acceptable salts thereof are useful in the treatment or prophylaxis of infection by HCMV and in the treatment, prophylaxis, or delay in the onset or progression of HCMV infection. Representative quinazoline compounds that are useful for treating HCMV infection are described, for example, in US Patent Patent No. 7, 196,086. Among the compounds disclosed in US7, 196,086, is (S)-2-(8-fluoro-3-(2-methoxy-5-(trifluoromethyl)phenyl)-2-(4-(3-methoxyphenyl)piperazin-l-yl)-3,4-dihydroquinazolin-4-yl)acetic acid, hereinafter referred to as Compound A. Compound A is a known inhibitor of HCMV terminase. The structure of Compound A is as follows:

Compound A

US Patent Nos. 7,196,086 and 8,084,604 disclose methodology that can be employed to prepare Compound A and related quinazoline-based HCMV terminase inhibitors. These methods are practical routes for the preparation of Compound A and related heterocyclic compounds.

EXAMPLE 6

Preparation of Compound A

To a slurry of compound 7 (20g, 18.9 mmol) in MTBE (40.0 mL) at room temperature was added a solution of sodium phosphate dibasic dihydrate (8.42 g, 47.3 mmol) in water (80 mL) and the resulting slurry was allowed to stir at room temperature for 40 minutes. The reaction mixture was transferred to a separatory funnel and the organic phase was collected and washed with a solution of sodium phosphate dibasic dihydrate (3.37 g, 18.91 mmol) in water (40.0 mL). A solution of KOH (4.99 g, 76 mmol) in water (80 mL) and methanol (10.00 mL) was then added to the organic phase and the resulting mixture was heated to 50 °C and allowed to stir at this temperature for 6 hours. MTBE (20 mL) and water (40 mL) were then added to the

reaction mixture and the resulting solution was transferred to a separatory funnel and the aqueous layer was collected and washed with MTBE (20 mL). Additional MTBE (40 mL) was added to the aqueous layer and the resulting solution was adjusted to pH 4-5 via slow addition of concentrated HCl. The resulting acidified solution was transferred to a separatory funnel and the organic phase was collected, concentrated in vacuo and solvent switched with acetone, maintaining a 30 mL volume. The resulting acetone solution was added dropwise to water and the precipitate formed was filtered to provide compound A as a white solid (10 g, 92%).

Abstract

Abstract Image

The development of a concise asymmetric synthesis of the antiviral development candidate letermovir is reported, proceeding in >60% yield over a total of seven steps from commercially available materials. Key to the effectiveness of this process is a novel cinchonidine-based PTC-catalyzed aza-Michael reaction to configure the single stereocenter.
