No. 60/528,974, filed Dec. 11, 2003. This application incorporates the entire content of U.S. patent application Ser. No. 11/008,713 and U.S. Provisional Patent Application Ser. No. 60/528,974.

TECHNICAL FIELD

The present invention relates to novel compounds and a composition and a method for inhibiting human immunodeficiency virus (HIV) protease, a composition and method for inhibiting or treating an HIV infection, processes for making the compounds and synthetic intermediates employed in the processes.

BACKGROUND OF THE INVENTION

The genome of the human immunodeficiency virus (HIV) encodes a protease that is responsible for the proteolytic processing of one or more polyprotein precursors such as the pol and gag gene products. HIV protease processes the gag precursor into core proteins and also processes the pol precursor into reverse transcriptase and protease.
The correct processing of the precursor polyproteins by HIV protease is necessary for the assembly of infectious virions. Therefore, inhibition of HIV protease provides a useful target for development of therapeutic agents for treatment of HIV infection.
In recent years, inhibitors of HIV protease have become an important class of therapeutic agents for inhibition and treatment of HIV infection in humans. HIV protease inhibitors are especially effective when administered in combination with other classes of HIV therapeutic agents, especially inhibitors of HIV reverse transcriptase, in “cocktails” of HIV therapeutic agents.
At the present time, the HIV protease inhibitors saquinavir, ritonavir, indinavir, nelfinavir, amprenavir, lopinavir/ritonavir, fosamprenavir, and atazanavir have been approved in the U.S. for treatment of HIV infection. There is a continuing need for improved HIV protease inhibitors that are very potent, that have reduced side-effects and that are effective against resistant strains of HIV.

As used herein, the terms “S” and “R” configuration are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem. (1976) 45, 13-30.
The compounds of the invention can comprise asymmetrically substituted carbon atoms. As a result, all stereoisomers of the compounds of the invention are meant to be included in the invention, including racemic mixtures, mixtures of diastereomers, as well as individual optical isomers, including, enantiomers and single diastereomers of the compounds of the invention substantially free from their enantiomers or other diastereomers. By “substantially free” is meant greater than about 80% free of other enantiomers or diastereomers of the compound, more preferably greater than about 90% free of other enantiomers or diastereomers of the compound, even more preferably greater than about 95% free of other enantiomers or diastereomers of the compound, even more highly preferably greater than about 98% free of other enantiomers or diastereomers of the compound and most preferably greater than about 99% free of other enantiomers or diastereomers of the compound.
In addition, compounds comprising the possible geometric isomers of carbon-carbon double bonds and carbon-nitrogen double are also meant to be included in this invention.
Individual stereoisomers of the compounds of this invention can be prepared by any one of a number of methods which are within the knowledge of one of ordinary skill in the art. These methods include stereospecific synthesis, chromatographic separation of diastereomers, chromatographic resolution of enantiomers, conversion of enantiomers in an enantiomeric mixture to diastereomers and then chromatographically separating the diastereomers and regeneration of the individual enantiomers, enzymatic resolution and the like.
Stereospecific synthesis involves the use of appropriate chiral starting materials and synthetic reactions which do not cause racemization or inversion of stereochemistry at the chiral centers.
Diastereomeric mixtures of compounds resulting from a synthetic reaction can often be separated by chromatographic techniques which are well-known to those of ordinary skill in the art.
Chromatographic resolution of enantiomers can be accomplished on chiral chromatography resins. Chromatography columns containing chiral resins are commercially available. In practice, the racemate is placed in solution and loaded onto the column containing the chiral stationary phase. The enantiomers are then separated by HPLC.
Resolution of enantiomers can also be accomplished by converting the enantiomers in the mixture to diastereomers by reaction with chiral auxiliaries. The resulting diastereomers can then be separated by column chromatography. This technique is especially useful when the compounds to be separated contain a carboxyl, amino or hydroxyl group that will form a salt or covalent bond with the chiral auxiliary. Chirally pure amino acids, organic carboxylic acids or organosulfonic acids are especially useful as chiral auxiliaries. Once the diastereomers have been separated by chromatography, the individual enantiomers can be regenerated. Frequently, the chiral auxiliary can be recovered and used again.
Enzymes, such as esterases, phosphatases and lipases, can be useful for resolution of derivatives of the enantiomers in an enantiomeric mixture. For example, an ester derivative of a carboxyl group in the compounds to be separated can be prepared. Certain enzymes will selectively hydrolyze only one of the enantiomers in the mixture. Then the resulting enantiomerically pure acid can be separated from the unhydrolyzed ester.
In addition, esters, amides, solvates and hydrates of the compounds of formula (I), (II), (III), (IV), (V), (VI), (VII), (VIII), (IX), (X), (XI), (XII) or (XIII) are meant to be included in this invention.

Antiviral Activity

Determination of Activity Against Wild-Type HIV or the Passaged Variants

MT4 cells were infected with 0.003 multiplicity of infection (MOI) of wild-type HIV-1 or the passaged mutant variants at 1×10⁶cells/mL for 1 h, washed twice to remove unabsorbed virus and resuspended to 1×10⁵cells/mL of medium, seeded in a 96-well plate at 100 μL/well, and treated with an equal volume of solution of inhibitor in a series of half log dilutions in RPMI 1640 (Rosewell Park Memorial Institute) media (Gibco) containing 10% fetal bovine serum (FBS), in triplicate. The final concentration of DMSO in all wells was 0.5%. The virus control culture was treated in an identical manner except no inhibitor was added to the medium. The cell control was incubated in the absence of inhibitor or virus. Plates were incubated for 5 days in a CO₂incubator at 37° C. On day 5, stock solution of 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) (4 mg/mL in PBS, Sigma cat. #M 5655) was added to each well at 25 μL per well. Plates were further incubated for 4 hrs, then treated with 20% sodium dodecyl sulfate (SDS) plus 0.02 N HCl at 50 μL per well to lyse the cells. After an overnight incubation, optical density (O.D.) was measured by reading the plates at 570/650 nm wavelengths on a Bio-Tek microtitre plate reader. Percent cytopathic effect (CPE) reduction was calculated from the formula below:
((O.D. test well−O.D. infected control well)/(O.D. uninfected control well−O.D. infected control well))×100
EC₅₀values were determined from the plot of log (Fa/Fu) vs. log (compound concentration) using the median-effect equation (Chou, 1975, Proc. Int. Cong. Pharmacol. 6^thp. 619) wherein Fa is the fraction inhibited by the compound, and Fu is the fraction uninhibited (1-Fa).
When tested by the above method, the compounds of the present invention exhibit EC₅₀in the range of 0.7 nM to >3.2 μM.

Determination of Anti-HIV Activity in the Presence of Human Serum

The above antiviral assay was performed in 96-well tissue culture plates containing 50% human serum (HS) (Sigma) plus 10% FBS (Gibco/BRL, Grand Island, N.Y.). Compounds were dissolved in DMSO, diluted at half log concentrations in DMSO, then transferred to media without serum at four times the final concentration. These solutions were added to 96-well plates at 50 μL per well, in triplicate. Cells were separately infected with 0.003 MOI of HIV-1 at 1×10⁶cells/mL for 1 hour, washed twice to remove unadsorbed virus and resuspended to 2×10⁵cells/mL of media without serum. The cell suspension (50 μL) was seeded at 1×10⁴cells per well. Uninfected cells were included as control. Final DMSO concentration in all wells was 0.5% including uninfected and infected control wells. Cultures were incubated for 5 days in a CO₂incubator at 37° C. EC₅₀values were measured using MTT uptake as described above.
When tested by the above method, compounds of the present invention exhibit EC₅₀in the range of 5 nM to >3.2 μM.

Generation of HIV-1 Resistant to ABT-378/r (A17) by In Vitro Passage

MT4 cells (2×10⁶) were infected with pNL4-3 at an MOI of 0.03 for 2 h, washed, then cultured in the presence of ABT-378 and ritonavir at concentration ratio of 5:1. The concentration of ABT-378 and ritonavir used in the initial passage was 1 nM and 0.2 nM respectively. Viral replication was monitored by determination of p24 antigen levels in the culture supernatant (Abbott Laboratories), as well as by observation for any cytopathic effect (CPE) present in the cultures. When p24 antigen levels were positive, the viral supernatant was harvested for the proceeding passage. Following each passage, the drug concentrations in the subsequent passage were gradually increased. After 5 months of selection, 1.5 μM of ABT-378 can be used in the final passage. The A17 virus was generated after 17 passages of pNL4-3 in the presence of ABT-378 and ritonavir at concentration ratio of 5:1.
When tested by the above method, compounds of the present invention inhibit the A17 virus with EC₅₀in the range of 0.3nM to >3.2 μM.
