The present disclosure relates to novel compounds for use in the treatment of a Retroviridae viral infection including an infection caused by the HIV virus. The present disclosure also relates to intermediates for its preparation and to pharmaceutical compositions containing those compounds.
Human immunodeficiency virus (HIV) infection and related diseases are a major public health problem worldwide. Human immunodeficiency virus type 1 (HIV-1) encodes three enzymes which are required for viral replication: reverse transcriptase, protease, and integrase. Several protease inhibitors (PI) are presently approved for use in AIDS or HIV. Yet many PI inhibitors suffer from high rates of hepatic metabolism, which may require co-administration of a booster or more frequent dosing. Furthermore, viral resistance remains a problem. Accordingly, there is a need for new agents that inhibit the replication of HIV.
The present disclosure provides compounds and methods for the treatment of an HIV infection. Accordingly, in one embodiment, the invention provides a compound of Formula I:

The following is a list of abbreviations and acronyms used throughout the application:
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. It must be noted that as used herein and in the appended claims, the singular forms “a”, “and”, and “the” include plural referents unless the context clearly dictates otherwise. Thus, e.g., reference to “the compound” includes a plurality of such compounds and reference to “the assay” includes reference to one or more assays and equivalents thereof known to those skilled in the art, and so forth.
A dash at the front or end of a chemical group is a matter of convenience; chemical groups may be depicted with or without one or more dashes without losing their ordinary meaning. A wavy line drawn through a line in a structure indicates a point of attachment of a group, e.g.:
A dashed line indicates an optional bond. Where multiple substituent groups are identified the point of attachment is at the terminal substituent (e.g. for “alkylaminocarbonyl” the point of attachment is at the carbonyl substituent).
The prefix “Cx-y” indicates that the following group has from x (e.g. 1) to y (e.g. 6) carbon atoms, one or more of which, in certain groups (e.g. heteroalkyl, heteroaryl, heteroarylalkyl, etc), may be replaced with one or more heteroatoms or heteroatomic groups. For example, “C1-6 alkyl” indicates that the alkyl group has from 1 to 6 carbon atoms. Likewise, the term “x-y membered” rings, wherein x and y are numerical ranges, such as “3 to 12-membered heterocyclyl”, refers to a ring containing x-y atoms (e.g. 3-12), of which up to 80% may be heteroatoms, such as N, O, S, P, and the remaining atoms are carbon.
Also, certain commonly used alternative chemical names may or may not be used. For example, a divalent group such as a divalent “alkyl” group, a divalent “aryl” group, etc., may also be referred to as an “alkylene” group or an “alkylenyl” group, or alkylyl group, an “arylene” group or an “arylenyl” group, or arylyl group, respectively.

“Hydroxyl” and “hydroxy” are used interchangeably and refer to —OH. “Oxo” refers to
Where tautomeric forms of the compound exist, hydroxyl and oxo groups are interchangeable.
It is understood that combinations of chemical groups may be used and will be recognized by persons of ordinary skill in the art. For instance, the group “hydroxyalkyl” would refer to a hydroxyl group attached to an alkyl group. A great number of such combinations may be readily envisaged. Additional examples of substituent combinations used herein include: C1-6 alkylamiocarbonyl (e.g. CH3CH2NHC(O)—) C1-6 alkoxycarbonyl (e.g. CH3O—C(O)—), 5-7 membered heterocyclyl-C1-6 alkyl (e.g. piperazinyl-CH2—), C1-6 alkylsulfonyl-5-7 membered heterocyclyl (e.g. CH3S(O)2-morpholinyl-), 5-7 membered heterocyclyl C1-6 alkoxy 5-7 membered heterocyclyloxy, (4-7 membered heterocyclyl)-4-7 membered heterocyclyl (e.g. oxetanyl-pyrrolidinyl-), C3-6cycloalkylaminocarbonyl (e.g. cyclopropyl-NH—C(O)—), 5-7 membered heterocyclyl-C2-6 alkynyl (e.g. N-piperazinyl-CH2C≡CCH2—), and C6-10 arylaminocarbonyl (e.g. phenyl-NH—C(O)—).
“Spiro” refers to a ring substituent which is joined by two bonds at the same carbon atom. Examples of spiro groups include 1,1-diethylcyclopentane, dimethyl-dioxolane, and 4-benzyl-4-methylpiperidine, wherein the cyclopentane and piperidine, respectively, are the spiro substituents. When substituents (R-groups) join together (e.g. when R7 and R8 join together) they may be taken from the same point of attachment to form a spiro ring.
The phrase “meta (3) position with respect to the point of attachment of the A ring”, refers to the position on the ring where the substituent (e.g. —CN) is adjoined and is shown below with an arrow, wherein z represents a carbon atom or nitrogen:
Similarly, para (4) position substitution refers to attachment of a substituent at the position indicated below, with respect to the point of attachment (e.g. of the B ring):
Similarly, ortho or 2-position refers to attachment of a substituent at the position indicated below, with respect to the point of attachment:
The compounds described herein include isomers, stereoisomers and the like. As used herein, the term “isomers” refers to different compounds that have the same molecular formula but differ in arrangement and configuration of the atoms. Also as used herein, the term “a stereoisomer” refers to any of the various stereo isomeric configurations which may exist for a given compound of the present invention and includes geometric isomers. It is understood that a substituent may be attached at a chiral center of a carbon atom. Therefore, the invention includes enantiomers, diastereomers or racemates of the compound.
The term “fused” refers to a ring which is bound to an adjacent ring.
“Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a “racemic” mixture.
The absolute stereochemistry is specified according to the Cahn-Ingold-Prelog R—S system. When a compound is a pure enantiomer the stereochemistry at each chiral carbon may be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (−) depending on the direction (dextro- or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. Certain of the compounds described herein contain one or more asymmetric centers and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)-. The present invention is meant to include all such possible isomers, including racemic mixtures, optically pure forms and intermediate mixtures. Optically active (R)- and (S)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituent may be E or Z configuration. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may have a cis- or trans-configuration. All tautomeric forms are also intended to be included. To the extent that compounds depicted herein are represented as having a particular stereochemistry, it is understood by one of skill in the art that such compounds may contain some detectable or undetectable levels of compounds sharing the same structure, but having different stereochemistry.
“IC95” or “EC95” refers to the inhibitory concentration required to achieve 95% of the maximum desired effect, which in many cases here is the inhibition of the HIV virus. This term is obtained using an in vitro assay evaluating the concentration-dependent inhibition of wild type HIV virus.
“IC50” or “EC50” refers to the inhibitory concentration required to achieve 50% of the maximum desired effect, which in many cases here is the inhibition of the HIV virus. This term is obtained using an in vitro assay evaluating the concentration-dependent inhibition of wild type HIV virus.
“IQ” or “inhibitory quotient” refers to the ratio between the trough drug concentration (Ctau) and level of drug resistance of the HIV isolate as determined by the IC95 (i.e. Ctau/IC95).
“Pharmaceutically acceptable” refers to compounds, salts, compositions, dosage forms and other materials which are useful in preparing a pharmaceutical composition that is suitable for veterinary or human pharmaceutical use.
“Pharmaceutically acceptable excipient” includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye/colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier which has been approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals.
“Pharmaceutically acceptable salt” refers to a salt of a compound that is pharmaceutically acceptable and that possesses (or can be converted to a form that possesses) the desired pharmacological activity of the parent compound. Such salts include acid addition salts formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like; or formed with organic acids such as acetic acid, benzenesulfonic acid, benzoic acid, camphorsulfonic acid, citric acid, ethanesulfonic acid, fumaric acid, glucoheptonic acid, gluconic acid, lactic acid, maleic acid, malonic acid, mandelic acid, methanesulfonic acid, 2-napththalenesulfonic acid, oleic acid, palmitic acid, propionic acid, stearic acid, succinic acid, tartaric acid, p-toluenesulfonic acid, trimethylacetic acid, and the like, and salts formed when an acidic proton present in the parent compound is replaced by either a metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or coordinates with an organic base such as diethanolamine, triethanolamine, N-methylglucamine and the like. Also included in this definition are ammonium and substituted or quaternized ammonium salts. Representative non-limiting lists of pharmaceutically acceptable salts can be found in S. M. Berge et al., J. Pharma Sci., 66(1), 1-19 (1977), and Remington: The Science and Practice of Pharmacy, R. Hendrickson, ed., 21st edition, Lippincott, Williams & Wilkins, Philadelphia, Pa., (2005), at p. 732, Table 38-5, both of which are hereby incorporated by reference herein.
The present disclosure also provides for prodrugs of the compounds disclosed herein. A “prodrug” is defined in the pharmaceutical field as a biologically inactive derivative of a drug that upon administration to the human body is converted to the biologically active parent drug according to some chemical or enzymatic pathway.
“Subject” and “subjects” refers to humans, domestic animals (e.g., dogs and cats), farm animals (e.g., cattle, horses, sheep, goats and pigs), laboratory animals (e.g., mice, rats, hamsters, guinea pigs, pigs, pocket pets, rabbits, dogs, and monkeys), and the like.
As used herein, “treatment” or “treating” is an approach for obtaining beneficial or desired results. For purposes of the present disclosure, beneficial or desired results include, but are not limited to, alleviation of a symptom and/or diminishment of the extent of a symptom and/or preventing a worsening of a symptom associated with a disease or condition. In one embodiment, “treatment” or “treating” includes one or more of the following: a) inhibiting the disease or condition (e.g., decreasing one or more symptoms resulting from the disease or condition, and/or diminishing the extent of the disease or condition); b) slowing or arresting the development of one or more symptoms associated with the disease or condition (e.g., stabilizing the disease or condition, delaying the worsening or progression of the disease or condition); and/or c) relieving the disease or condition, e.g., causing the regression of clinical symptoms, ameliorating the disease state, delaying the progression of the disease, increasing the quality of life, and/or prolonging survival.
As used herein, “delaying” development of a disease or condition means to defer, hinder, slow, retard, stabilize and/or postpone development of the disease or condition. This delay can be of varying lengths of time, depending on the history of the disease and/or subject being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the subject does not develop the disease or condition. For example, a method that “delays” development of AIDS is a method that reduces the probability of disease development in a given time frame and/or reduces extent of the disease in a given time frame, when compared to not using the method. Such comparisons may be based on clinical studies, using a statistically significant number of subjects. For example, the development of AIDS can be detected using known methods, such as confirming a subject's HIV+ status and assessing the subject's T-cell count or other indication of AIDS development, such as extreme fatigue, weight loss, persistent diarrhea, high fever, swollen lymph nodes in the neck, armpits or groin, or presence of an opportunistic condition that is known to be associated with AIDS (e.g., a condition that is generally not present in subjects with functioning immune systems but does occur in AIDS patients). Development may also refer to disease progression that may be initially undetectable and includes occurrence, recurrence and onset.
As used herein, “prevention” or “preventing” refers to a regimen that protects against the onset of the disease or disorder such that the clinical symptoms of the disease do not develop. Thus, “prevention” relates to administration of a therapy (e.g., administration of a therapeutic substance) to a subject before signs of the disease are detectable in the subject (e.g., administration of a therapeutic substance to a subject in the absence of detectable infectious agent (e.g., virus) in the subject). The subject may be an individual at risk of developing the disease or disorder, such as an individual who has one or more risk factors known to be associated with development or onset of the disease or disorder. Thus, the term “preventing HIV infection” refers to administering to a subject who does not have a detectable HIV infection an anti-HIV therapeutic substance. It is understood that the subject for anti-HIV preventative therapy may be an individual at risk of contracting the HIV virus. Further, it is understood that prevention may not result in complete protection against onset of the disease or disorder. In some instances, prevention includes reducing the risk of developing the disease or disorder. The reduction of the risk may not result in complete elimination of the risk of developing the disease or disorder.
As used herein, an “at risk” individual is an individual who is at risk of developing a condition to be treated. An individual “at risk” may or may not have detectable disease or condition, and may or may not have displayed detectable disease prior to the treatment of methods described herein. “At risk” denotes that an individual has one or more so-called risk factors, which are measurable parameters that correlate with development of a disease or condition and are known in the art. An individual having one or more of these risk factors has a higher probability of developing the disease or condition than an individual without these risk factor(s). For example, individuals at risk for AIDS are those having HIV.
As used herein, the term “therapeutically effective amount” or “effective amount” refers to an amount that is effective to elicit the desired biological or medical response, including the amount of a compound that, when administered to a subject for treating a disease, is sufficient to effect such treatment for the disease or to an amount that is effective to protect against the contracting or onset of a disease. The effective amount will vary depending on the compound, the disease, and its severity and the age, weight, etc., of the subject to be treated. The effective amount can include a range of amounts. As is understood in the art, an effective amount may be in one or more doses, i.e., a single dose or multiple doses may be required to achieve the desired treatment outcome. An effective amount may be considered in the context of administering one or more therapeutic agents, and a single agent may be considered to be given in an effective amount if, in conjunction with one or more other agents, a desirable or beneficial result may be or is achieved. Suitable doses of any co-administered compounds may optionally be lowered due to the combined action (e.g., additive or synergistic effects) of the compounds.
The compounds of the invention include solvates, hydrates, tautomers, stereoisomers and salt forms thereof.
Provided are also compounds in which from 1 to n hydrogen atoms attached to a carbon atom may be replaced by a deuterium atom or D, in which n is the number of hydrogen atoms in the molecule. As known in the art, the deuterium atom is a non-radioactive isotope of the hydrogen atom. Such compounds exhibit may increase resistance to metabolism, and thus may be useful for increasing the half-life of the compounds when administered to a mammal. See, e.g., Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism,” Trends Pharmacol. Sci., 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogen atoms have been replaced by deuterium.
Examples of isotopes that can be incorporated into the disclosed compounds also include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, chlorine, and iodine, such as 2H, 3H, 11C, 13C, 14C, 13N, 13N, 15N, 15O, 17O, 18O, 31P, 32P, 32P, 35S, 18F, 36Cl, 123I, and 125I, respectively. Substitution with positron emitting isotopes, such as 11C, 18F, 15O and 13N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. Isotopically-labeled compounds of Formula (Ia) or (Ib), can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the Examples as set out below using an appropriate isotopically-labeled reagent in place of the non-labeled reagent previously employed.

Sections 2.1-2.4 show preparation of Intermediate I, Intermediate P, Intermediate S, and Intermediate A, as used herein. Section 3 provides example syntheses and compounds. Section 4 shows biological activity.
Scheme 1.1 shows a general synthesis of a compound within the scope of Formula I beginning with reductive amination of compound 1.1a with a substituted benzaldehyde (Intermediate P). Reductive amination may be accomplished, for example, with a cyanoborohydride reagent such as sodium cyanoborohydride. Subsequent metal-catalyzed coupling such as Sonogashira- or Suzuki-couplings. Sonogashira coupling of compound 1.1b with an alkynyl Intermediate Sa gives a compound of Formula I.
Examples 1-130, 219, and 224-245 were prepared by this general strategy (by reductive amination of the appropriate Intermediate P with the corresponding organohalide peptide Intermediate I, followed by Sonogashira coupling with the appropriate Intermediate S).

Exemplary protecting groups (PG) for compound 1.2a include t-butylcarbonyl (BOC) protecting group and fluuorenylmethyloxycarbonyl (FMOC). Reductive amination of compound 1.2a with a substituted benzaldehyde Intermediate P gives compound 1.2b after removal of the protecting groups. Reductive amination may be accomplished, by way of non-limiting example, with sodium cyanoborohydride. HATU coupling of compound 1.2b with an amino acid Intermediate Am gives a compound 1.2c. Sonogashira coupling of compound 1.2c with an alkyne Intermediate Sa gives a compound of Formula I.
Examples 133-180 and 220 were prepared by this general strategy (reductive amination of the appropriate P with an amino hydrazinyl iodophenyl butanol followed by HATU coupling Am, which is then followed by Sonogashira coupling with an alkynyl Intermediate Sa). Example 133 provides exemplary reaction conditions and reagents appropriate for preparing a compound of Formula I according to Scheme 1.2.
Scheme 1.3 shows a general synthesis of a compound within the scope of Formula I beginning with reductive amination of a protected organohalide compound 1.3a with a benzaldehyde Intermediate P and Boc removal to give compound 1.3b.

Boc removal may be accomplished, by way of non-limiting examples, with trifluoroacetic acid or hydrochloric acid. HATU coupling of compound 1.3b with an amino acid Intermediate Am gives the intermediate peptide 1.3c. Sonogashira coupling of the intermediate peptide 1.3c and an alkynyl Intermediate S gives intermediate 1.3d. Subsequent reaction of compound 1.3d with an acyl chloride gives a compound of Formula I.
Examples 183-186 were prepared by this general strategy. Example 183 provides exemplary reaction conditions and reagents appropriate for preparing a compound of the invention according to Scheme 1.3.

Xphos is also known as XPhos is 2-Dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl. Pd G2 is chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2′-amino-1,1′-biphenyl)]palladium(II). Examples 202-211 and 218 were prepared according to Scheme 1.5. Example 202 provides exemplary reaction conditions for this transformation.
Example 212 was made in according to Scheme 1.6. Example 212 provides exemplary reaction conditions for transformations according to Scheme 1.6.

Examples 214-217 show installation of different R2 and R3 groups using the same general strategy and the appropriate acid chloride.
Scheme 1.8 shows a general synthesis of a compound within the scope of Formula I beginning with reductive animation of compound 1.8a with a substituted benzaldehyde (Intermediate P). Reductive animation of compound 1.8a with a substituted benzaldehyde Intermediate P gives compound 1.8b. Reductive animation may be accomplished, by way of non-limiting example, with sodium cyanoborohydride. Subsequent epoxide opening of tert-butyl ((S)-2-(4-iodophenyl)-1-((R)-oxiran-2-yl)ethyl)carbamate give compound 1.8c. Subsequent Boc removal followed by Subsequent amide bond formation gives compound 1.8d. Boc removal may be accomplished, by way of non-limiting examples, with trifluoroacetic acid or hydrochloric acid. Amide bond formation may be accomplished, by way of non-limiting example, with a carboxylic acid and a reagent, such as HATU. Subsequent protecting group removal gives compound 1.8e. Subsequent amide bond formation gives compound 1.8f. Amide bond formation may be accomplished, by way of non-limiting example, with a carboxylic acid and a reagent, such as HATU. Subsequently metal-catalyzed coupling such as Sonogashira- or Suzuki-couplings may be performed. Sonogashira coupling of compound 1.8d with an alkynyl Intermediate Sa gives a compound of Formula I.

Compounds were tested in a high-throughput 384-well assay format for their ability to inhibit the replication of HIV-1 (IIIB) in MT-4 cells. Compounds were serially diluted (1:3) in DMSO on 384-well polypropylene plates and further diluted 200-fold into complete RPMI media (10% FBS, 1% P/S) using the Biotek Micro Flow and Agilent ECHO acoustic dispenser. Each plate contained up to 8 test compounds, with negative (No Drug Control) and 5 uM AZT positive controls. MT-4 cells were pre-infected with 10 uL of either RPMI (mock-infected) or a fresh 1:250 dilution of an HIV-1 (IIIB) concentrated virus stock. Infected and uninfected MT-4 cells were further diluted in complete RPMI media and added to each plate using a Micro Flow dispenser. After 5 days incubation in a humidified and temperature controlled incubator (37° C.), Cell Titer Glo (Promega) was added to the assay plates to quantify the amount of luciferase. EC50 and CC50 values were defined as the compound concentration that causes a 50% decrease in luminescence signal, and were calculated using a sigmoidal dose-response model to generate curve fits. Data for certain compounds is reported in Table 1 below.
Assay protocol is identical to that described for the MT-4 antiviral assay with the following changes: Each drug is run in 2 series of quadruplicates with different starting concentrations for each series and 19 1.5 fold dilutions performed across the plate. This results in an inhibition curve with 40 data points for each compound. Data is analyzed and Hill coefficients determined in Graph Pad Prism (San Diego, Calif.). EC95S were determined by the formula EC95=(19)1/hill coefficient×EC50. HD values were determined for certain compounds and reported in Table 5 below as an illustrative example.

At an incubation temperature of 37° C., the reaction was started with addition of NADPH Regeneration System, at each time point, 25 uL of the reaction mixture was removed and added to a plate with 225 uL quenching solution (50% MeOH, 25% ACN, 25% H2O, and 200 nM labetalol as internal standard). After plates were vortexed, they were centrifuged for 30 minutes to remove proteins. About 100 μL supernatant was removed to a new plate and diluted with 150 μL water. About 20 μL of the mixture was injected into LC/MS/MS system to monitor the compound's response. In vitro measured t1/2 was used to calculate Clint values. Data is presented in Table 1 below and

Drug EC50 values versus PI resistant mutant viruses for certain compounds were determined in a 5-day multi-cycle cell viability assay measuring protection from cytopathic effect (CPE). Briefly, MT-2 cells were bulk infected at a density of 2×106 cells/mL with WT or mutant viruses at a multiplicity of infection (MOI) of 0.01 by gently rocking the culture for 3 hours at 37° C. and then added in triplicate to 96-well plates (Corning Life Sciences, Tewksbury, Mass., USA). Cells were incubated in complete RPMI medium containing a 10-point, 3-fold serial drug dilution (0.5% final DMSO concentration) for five days at 37° C. in 5% CO2. After this time, 100 μL of CellTitert-Glo reagent (Promega, Madison, Wis., USA) was added to each well and the luminescence signals quantified on an EnVision plate reader (Perkin-Elmer, Inc., Waltham, Mass., USA). EC50 values, defined as the drug concentration inducing a 50% protection from HIV-induced cell killing, were calculated from a minimum of three independent experiments performed in quadruplicate using XLFit™ software (IDBS, Ltd., Guildford, Surrey, UK) and nonlinear regression analysis. As an illustrative example, data associated with the compound of Example 58 (GSPI1) is presented in
MT-2 cells were infected with HIV-1IIIB (Advanced Biotechnologies, Eldersburg, Md., USA) at a relatively high multiplicity of infection (MOI=0.05) for 3 hours and plated in 24-well plates at 2×105 cells per well. Drugs were added 16 hours later to a minimum of quadruplicate wells at fixed multiples of their EC50 values. Every 3-4 days, cells were diluted (1:5) into freshly prepared cell culture media containing drug concentrations at the same multiple of EC50 values and monitored for virus-induced cytopathic effects (CPE) over a period of 32 days. Cell-free viral supernatants were harvested from wells showing >80% CPE and kept frozen at −80° C. until further analyzed. As an illustrative example, data associated with the compound of Example 58 (GSPI1) is presented in
Total RNA was purified from the cell-free supernatants obtained from each CPE-positive and p24-positive well using the Qiagen Viral RNA Isolation kit (Qiagen, Valencia, Calif., USA). The coding regions targeted by each drug were amplified by One-Step RT-PCR (Qiagen) and the products subjected to DNA sequencing. Sequence changes were identified by alignment with input virus sequences using Sequencher (Gene Codes Corp., Ann Arbor, Mich., USA) and amino acid substitutions determined.
Pooled plasma (from at least 3 males and 3 females) was from Bioreclamation IVT. Sodium EDTA was used as the anticoagulant. 10% plasma was diluted in in 0.133M phosphate buffer consisted of 1.5% (w/v) Sodium EDTA.
RPMI cell culture media consisted 10% FBS was provided by biology department, Gilead Sciences, Inc.
Plasma protein binding assay: Studies were conducted in duplicate or triplicate using a Dianorm Equilibrium Dialyser (Harvard Apparatus, Holliston Mass.) with each cell consisting of a semipermeable membrane (2.4 cm working diameter) separating two 1 mL PTFE half-cells (Weder H G, Schildknecht J, Kesselring P. A new equilibrium dialyzing system. American Laboratory. 1971; 10: 15-21). Prior to the study, the dialysis membrane was soaked for approximately one hour in 0.133 M phosphate buffer, pH 7.4. 10% plasma and cell culture media spiked with 1 pM compound (1 mL) were placed into opposite sides of the assembled dialysis cells and the dialysis cells were then rotated slowly in a 37° C. water bath. After the equilibration period, matrix-containing samples from both sides were drained into pre-weighed polypropylene tubes. Post-dialysis 10% plasma samples were transferred into centrifuge tubes containing 1 mL of blank cell culture media. Post-dialysis cell culture media samples were transferred into centrifuge tubes containing 1 mL of blank 10% plasma. All samples weights were measured and recorded for calculations of volume shift and recovery.
Samples were deproteinated by treatment with four volumes of 90% (v/v) acetonitrile, 10% (v/v) methanol containing the LC-MS internal standard. Samples were centrifuged 15,000 rpm at 4° C. for 15 min and 200 μL aliquots of the supernatants removed and mixed with an equal volume of water. Samples were vortexed for 2 min, and then aliquots (10 L) subject to LC-MS/MS analysis.
The binding ratio for an analyte in plasma vs. cell culture media was calculated using the following equations:
Ratio=C10% plasma/CCCM
where C10% plasma is the post-dialysis 10% plasma concentration (determined by PAR), and CCCM is the post-dialysis cell culture media concentration (determined by PAR), respectively. Each concentration was corrected gravimetrically for changes in liquid volume in the dialysis cells occurring during dialysis.
Inhibitor potency was measured using an enzymatic assay with a fluorogenic readout. To a reaction buffer containing 100 mM ammonium acetate at pH 5.3, 100 mM NaCl, 1 mM EDTA, 1 mM DTT, 0.25 mg/mL BSA and 1% DMSO were added 2.5 nM of recombinant HIV protease and test compound at one of various concentrations. After a 20-minute pre-incubation, the enzymatic reaction was initiated by the addition of the fluorogenic substrate (2-aminobenzoyl)Thr-Ile-Nle-(p-nitro)Phe-Gln-Arg (Bachem) to a final concentration of 40 μM. The total volume of the assay solution was 100 □L. The reaction was measured over 20 minutes on a Tecan Infinite M1000 plate reader using an excitation wavelength of 320 nm and a detection wavelength of 420 nm. The slopes of the progress curves were the measure of reaction rates. Reaction rates were plotted as a function of inhibitor concentration, and the data were fit using the tight-binding equation described by Morrison (Biochim. Biophys. Acta 1969, 185, 269-286) to yield Ki values.
