Description
[Technical field]
[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 313,160, filed February 23, 2022, which is incorporated by reference herein in its entirety for all purposes.
[0002] FIELD OF THEINVENTION The present invention relates to compositions and methods for modulating the glucagon-like peptide-1 (GLP-1) receptor. [Background technology]
[0003] Diabetes mellitus has become a major public health concern due to its increasing prevalence and associated health risks. The disease is characterized by hyperglycemia resulting from defects in insulin production, insulin action, or both. Two major forms of diabetes are recognized: type 1 and type 2. Type 1 diabetes (T1D) develops when the body's immune system destroys pancreatic beta cells, the only cells in the body that make the hormone insulin, which regulates blood sugar. Type 1 diabetes patients need to receive insulin through injections or pumps to survive. Type 2 diabetes mellitus (T2DM) usually begins with insulin resistance or when there is not enough insulin production to maintain acceptable blood sugar levels.
[0004] Currently, various pharmacological approaches are available for the treatment of hyperglycemia and subsequent T2DM (Hampp, C. et al. Use of Antidiabetic Drugs in the US, 2003-2012, Diabetes Care 2014, 37, 1367-1374). One of them is the glucagon-like peptide 1 receptor (GLP-1R) agonists (e.g., liraglutide, albiglutide, exenatide, lixisenatide, dulaglutide, semaglutide), which act on the beta cells of the pancreas to promote insulin secretion. Commercially available GLP-1R agonists are peptides administered by subcutaneous injection. Liraglutide has further been approved as a treatment for obesity.
[0005] GLP-1 is a 30 amino acid long incretin hormone secreted by L-cells in the intestine in response to food ingestion. GLP-1 has been shown to stimulate insulin secretion in a physiological and glucose-dependent manner, decrease glucagon secretion, inhibit gastric emptying, reduce appetite, and stimulate beta cell proliferation. In preclinical experiments, GLP-1 promotes continued beta cell capacity by stimulating the transcription of genes important for glucose-dependent insulin secretion and promoting beta cell neogenesis (Meier et al. Biodrugs. 2003;17(2):93-102).
[0006] In healthy individuals, GLP-1 plays a key role in regulating postprandial blood glucose levels by stimulating glucose-dependent insulin secretion by the pancreas and increasing peripheral glucose absorption. GLP-1 also inhibits glucagon secretion, leading to reduced hepatic glucose output. In addition, GLP-1 delays gastric emptying and slows small intestinal motility, slowing food absorption. In patients with T2DM, the normal postprandial rise in GLP-1 is absent or reduced (Vilsboll T, et al. Diabetes. 2001.50;609-613).
[0007] Holst (Physiol. Rev. 2007, 87, 1409) and Meier (Nat. Rev. Endocrinol. 2012, 8, 728) explain that GLP-1 receptor agonists such as liraglutide and exendin-4 have three main pharmacological activities that improve glycemic control in patients with T2DM by lowering fasting and postprandial plasma glucose levels (FPG and PPG): (i) increasing glucose-dependent insulin secretion (improving phase 1 and phase 2), (ii) glucagon suppression activity under hyperglycemic conditions, and (iii) slowing the absorption of glucose from a meal by slowing the rate of gastric emptying.

[0120] The 5-(6-(aryloxy)pyridin-2-yl)-2-azabicyclo[4.1.0]heptane intermediate A7 is reacted with an appropriate R1-substituted benzimidazole-6-carboxylic acid ester B1 (prepared according to various known synthetic methods such as those described in WO2019239371) in the presence of an acid scavenger such as an alkali carbonate to obtain a mixture of four diastereomers with (1R,5R,6R), (1R,5S,6R), (1S,5R,6S) and (1S,5S,6S) configurations. The intermediate mixture of diastereomers is separated by supercritical fluid chromatography (SFC) and then each individual compound is saponified with an alkali hydroxide to obtain the final products B2, B3, B4, and B5. Alternatively, intermediate A7 can be prepared in a stereoselective synthesis or purified to obtain only the desired isomer for use in the subsequent steps.

[0136] The 5-((S)-2-methyl-2-substituted-arylbenzo[d][1,3]dioxol-4-yl)-2-azabicyclo[4.1.0]heptane intermediate F7 is reacted with the appropriate R1-substituted benzimidazole-6-carboxylic acid ester B1 (prepared according to various known synthetic methods such as those described in WO2019239371) in the presence of an acid scavenger such as an alkali carbonate to give a mixture of four diastereomers with (1R,5R,6R), (1R,5S,6R), (1S,5R,6S) and (1S,5S,6S) configurations. The intermediate mixture of diastereomers is separated by supercritical fluid chromatography (SFC) and then each individual compound is saponified with alkali hydroxide to give the final products J1, J2, J3 and J4.

[0142] Horner-Wadsworth-Emmols olefination of commercially available tert-butyl 5-oxo-2-azabicyclo[4.1.0]heptane-2-carboxylate and phosphonate M2A gives 2-((2-(tert-butoxycarbonyl)-2-azabicyclo[4.1.0]heptane-5-ylidene)methyl)-1-substituted-1H-benzo[d]imidazole-6-carboxylate M3, which is reduced and deprotected with strong acid.

[0144] Nucleophilic displacement of commercially available 3-fluoro-4-nitrobenzonitrile with the desired amine, R1NH2, followed by reduction and condensation with 2-chloro-1,1,1-trimethoxyethane gives 2-(chloromethyl)-1-substituted-1H-benzo[d]imidazole-6-carbonitriles N4. Reaction of N4 with 5-(6-(aryloxy)pyridin-2-yl)-2-azabicyclo[4.1.0]heptane intermediate A7 in the presence of an acid scavenger such as an alkali carbonate gives N5.

[0151] GLP-1R Cellular Assay
[0152] Stable cell lines expressing high and low GLP-1R surface expression were generated in CHO-K1 cells (Fugene6) transfected with a puromycin-selectable DNA plasmid (deposition number: NM_002062.5) encoding the human GLP-1R receptor under the control of the EF1A promoter. Transfected cells were seeded in 24-well plates (9,000 cells / well) containing complete medium and incubated in a humidified incubator at 37 °C with 5% carbon dioxide. After overnight incubation, the medium was replaced with complete medium supplemented with puromycin (6 μg / mL) and refreshed every 2–3 days to select for stably transfected cells. Individual pools of selected cells were expanded and then analyzed for responsiveness to a GLP-1 control peptide using a TR-FRET assay for detecting cAMP (LANCE UltracAMP assay, PerkinElmer). Briefly, cells were harvested in Versene solution, plated in 384-well plates (1,000 cells / well) and mixed with serially diluted GLP-1R control peptide (10 nL) using an acoustic dispenser (ECHO). After incubating the plate for 30 min at 25°C, EU-cAMP tracer (5 μL) and Ulight-anti-cAMP reagent (5 μL) were added to each well, followed by incubation for 15 min at 25°C. TR-FRET signals were detected using an EnVision multimode plate reader (excitation = 320 nm, emission = 615 and 655 nm). Dose-response curves were used to measure EC as a measure of responsiveness to the GLP-1R control peptide. 50Values were generated. The responsiveness of selected cell lines was monitored over multiple passages to ensure stability. CHO-K1_hGLP-1Rhigh_clone16 and CHO-K1_hGLP-1Rlow_clone10 showed consistently high and low responsiveness to the GLP-1R control peptide, respectively, and were selected for further analysis to determine the relative levels of GLP-1R surface expression. Briefly, GLP-1R expression was analyzed by flow cytometry using a fluorescein-labeled Exendin-4 peptide fluorescent probe (FLEX). Cells were harvested in Versene solution and washed three times with PBS+0.5% BSA before being incubated with FLEX reagent (10 μM) for 2 h at room temperature. After incubation, cells were washed three times with PBS+0.5% BSA and finally resuspended in PBS before analysis by flow cytometry to measure FLEX mean fluorescence intensity (MFI) as a measure of cell surface GLP-1R expression.
[0153] For compound testing in the CHO-K1_hGLP-1Rlow_clone10 cell line, cells were seeded in 384-well plates (1,000 cells / well). Test compounds were serially diluted in DMSO (10-point, 3-fold dilutions) and added to the wells (10 nL / well) using an ECHO dispenser, the plates were centrifuged for 1 min, agitated for 2 min at room temperature, and then incubated for 30 min at 25°C. After incubation, Eu-cAMP (5 μL) and Ulight-anti-cAMP (5 μL) reagents were added to each well, followed by centrifugation for 1 min, agitation for 2 min at room temperature, and a final incubation of the plates for 15 min at 25°C. Plates were read using an EnVision microplate reader (excitation = 320 nm, emission = 615 and 655 nm). Dose-response curves were generated from duplicate wells based on percent activation calculated compared to a control GLP-1 peptide agonist run in parallel. EC 50 Values were determined by fitting the percent activation as a function of compound concentration using the Hill equation (XLfit).
[0154] The EC50 values of exemplary compounds 1 and 2 in the low expression assay are shown in the table below. The EC50 values were compared with reference compound A and reference compound B. The compounds tested were compound samples prepared according to the general procedures described in the Examples section.
[0155] Metabolic stability of hepatocytes
[0156] Test compounds were incubated with human hepatocytes to assess stability from a stromal depilation approach. Test compounds were dissolved in dimethyl sulfoxide (DMSO) to make 10 mM stock solutions and further diluted to make 1000x 1 mM working stock solutions with DMSO in 96-well plates for test compounds and positive control (midazolam). Vials containing cryopreserved hepatocytes were removed from the liquid nitrogen tank and immediately immersed in a 37°C water bath. The vials were gently shaken until the contents were thawed and then immediately poured into 48 mL of pre-warmed HT medium in a 50 mL conical tube. The cells remaining in the vial were resuspended in 1.0 mL of pre-warmed HT medium and added to the conical tube. The tube was capped and then gently inverted several times to resuspend the hepatocytes. The cell suspension was centrifuged at 50 x g for 5 min at room temperature and the supernatant was discarded. The cell pellet was loosened by gently swirling the tube and resuspended in 4 mL of warm Dulbecco's Modified Eagle Medium (DMEM). Cell density was determined using a Nexcelom cell counter, and DMEM medium was added to obtain a target density of 1 x 106 cells / mL. The assay was performed in 96-well microtiter plates. Test compounds were added at 1 x 10 at 1 μM in DMEM. 6The mixtures were incubated with 10000 cells / mL hepatocytes for 0, 30, 60, 120 and 240 min. Incubations were performed at 37°C in a humidified atmosphere of 95% air / 5% CO2 with gentle shaking. The volume of the incubation mixture was 37 μL with 0.1% DMSO final. At each time point, the incubation was stopped by adding 150 μL of quenching solution (100% acetonitrile, 0.1% formic acid with bucetin as internal standard for positive ESI mode). The mixtures were then vortexed for 20 min and centrifuged at 4,000 RPM at 10°C. The supernatants (80 μL) were transferred to a clean 96-well plate and analyzed by LC-MS / MS. Midazolam at 1 μM with 0.1% DMSO final was included as a positive control to validate the assay performance. Percentage of parent remaining, intrinsic and predicted hepatic clearance, and t 1 / 2 was calculated. All samples were analyzed by LC-MS / MS using an AB Sciex API4000 instrument connected to a Shimadzu LC-20ADLC pump system. Separation was achieved using a Waters AtlantisT3 dC18 reversed-phase HPLC column (20mmx2.1mm) at a flow rate of 0.5mL / min. The mobile phase consisted of 0.1% formic acid in water (solvent A) and 0.1% formic acid in 100% acetonitrile (solvent B). The elution conditions are detailed below. [Table 2]
[0157] The ion optics for each test compound were optimized for declustering potential (DP), collection energy (CE), and collision cell exit potential (CXP) and used for selected ion monitoring experiments in positive ion mode. The peak area ratio of each test compound relative to the internal standard was then assessed for stability. The extent of metabolism was calculated based on the disappearance of the test compound compared to the initial concentration. The initial rate of clearance of the test compound was calculated using a linear regression plot of the semi-log % remaining of the compound versus time. The elimination rate constant (k) from the linear regression plot was then used to calculate the t using the following equation: 1 / 2and inherent clearance (CL int ) was determined, where C 肝細胞 (million cells / mL) is the cell density of the incubation: k=-slope t 1 / 2 =0.693 / k CL int =k / C 肝細胞
[0158] This method of intrinsic clearance measurement assumes that the concentration of the test compound is much lower than the compound's Michaelis-Menten constant for its metabolic enzyme.
[0159] Predicted hepatic clearance (CL hep ) is the normalized CL based on liver weight int(インビボ) The mixture was calculated using the well-stirred method using the following formula: CL int(インビボ) =CL int × Hepatocellular × Liver weight CL hep予測値 =(CL int(インビボ) ×Q 肝臓 ) / (CL int(インビボ) +Q 肝臓 ) Here, Q 肝臓 (ml / min / kg) is the hepatic blood flow
[0160] Physiological parameters related to human liver weight, blood flow, and hepatocellularity are given below. [Table 3]
[0161] Passive permeability and flux ratio
[0162] Caco-2 cells (clone C2BBe1) were obtained, for example, from the American Type Culture Collection (Manassas, VA). Cell monolayers were grown to confluence on collagen-coated microporous membranes in 12-well assay plates. The permeability assay buffer was Hanks' balanced salt solution, pH 7.4, containing 10 mM HEPES and 15 mM glucose. The buffer in the receiver chamber also contained 1% bovine serum albumin. The concentration of the dosing solution was 5 μM of the test substance in assay buffer. Cell monolayers were dosed apically (A-to-B) or basolaterally (B-to-A) and incubated at 37°C with 5% CO2 in a humidified incubator. Samples were taken from the donor and receiver chambers at 120 min. Each measurement was performed in duplicate. Lucifer Yellow flux was also measured after the experiment for each monolayer to ensure that no damage was done to the cell monolayer during the flux period. All samples were analyzed by LC-MS / MS using electrospray ionization. app ) and the recovery rate were calculated as follows: P app =(dC r / dt) × V r / (A×C A ) (1) Recovery rate = 100 × ((V r ×C r 最終 )+(V d ×C d 最終 )) / (V d ×C N ) (2) In the formula, dC r / dt is the slope of the cumulative receiver concentration versus time (μMs -1 ) and V r is the volume of the receiver compartment (cm 3 ) and V d is the volume of the donor compartment (cm 3 ), and A is the area of the insert (1.13 cm for 12 wells). 2 ) and C Ais the mean of the nominal dose concentration and the measured donor concentration over 120 min (μM), and C N is the nominal concentration of the dosing solution (μM), and C r 最終 is the cumulative receiver concentration at the end of the incubation period (μM), and C d 最終 is the donor concentration (μM) at the end of the incubation period. The efflux ratio (ER) is the ratio of P app (B-to-A) / P app It is defined as (A-to-B).

[0271] Biotechnology Example B1: GLP-1R cell アッセイ Stable cell lines expressing high and low GLP-1R surface expression were generated in CHO-K1 cells (Fugene6) transfected with a puromycin-selectable DNA plasmid (deposition number: NM_002062.5) encoding the human GLP-1R receptor under the control of the EF1A promoter. Transfected cells were seeded in 24-well plates (9,000 cells / well) containing complete medium and incubated in a humidified incubator at 37 °C with 5% carbon dioxide. After overnight incubation, the medium was replaced with complete medium supplemented with puromycin (6 μg / mL) and refreshed every 2–3 days to select for stably transfected cells. Individual pools of selected cells were expanded and then analyzed for responsiveness to a GLP-1 control peptide using a TR-FRET assay for detecting cAMP (LANCE UltracAMP assay, PerkinElmer). Briefly, cells were harvested in Versene solution, plated in 384-well plates (1,000 cells / well) and mixed with serially diluted GLP-1R control peptide (10 nL) using an acoustic dispenser (ECHO). After incubating the plate for 30 min at 25°C, EU-cAMP tracer (5 μL) and Ulight-anti-cAMP reagent (5 μL) were added to each well, followed by incubation for 15 min at 25°C. TR-FRET signals were detected using an EnVision multimode plate reader (excitation = 320 nm, emission = 615 and 655 nm). Dose-response curves were used to measure EC as a measure of responsiveness to the GLP-1R control peptide. 50Values were generated. The responsiveness of selected cell lines was monitored over multiple passages to ensure stability. CHO-K1_hGLP-1Rhigh_clone16 and CHO-K1_hGLP-1Rlow_clone10 showed consistently high and low responsiveness to the GLP-1R control peptide, respectively, and were selected for further analysis to determine the relative levels of GLP-1R surface expression. Briefly, GLP-1R expression was analyzed by flow cytometry using a fluorescein-labeled Exendin-4 peptide fluorescent probe (FLEX). Cells were harvested in Versene solution and washed three times with PBS+0.5% BSA before being incubated with FLEX reagent (10 μM) for 2 h at room temperature. After incubation, cells were washed three times with PBS+0.5% BSA and finally resuspended in PBS before analysis by flow cytometry to measure FLEX mean fluorescence intensity (MFI) as a measure of cell surface GLP-1R expression. Both cell lines showed higher MFI values compared to control CHO-K1 cells, confirming GLP-1R surface expression. CHO-K1_hGLP-1Rhigh_clone16 cells showed significantly higher MFI levels compared to CHO-K1-hGLP-1low_clone10 cells.
[0272] For compound testing in the CHO-K1_hGLP-1Rlow_clone10 cell line, cells were seeded in 384-well plates (1,000 cells / well). Test compounds were serially diluted in DMSO (10-point, 3-fold dilutions) and added to the wells (10 nL / well) using an ECHO dispenser, the plates were centrifuged for 1 min, agitated for 2 min at room temperature, and then incubated for 30 min at 25°C. After incubation, Eu-cAMP (5 μL) and Ulight-anti-cAMP (5 μL) reagents were added to each well, followed by centrifugation for 1 min, agitation for 2 min at room temperature, and a final incubation of the plates for 15 min at 25°C. Plates were read using an EnVision microplate reader (excitation = 320 nm, emission = 615 and 655 nm). Dose-response curves were generated from duplicate wells based on percent activation calculated compared to a control GLP-1 peptide agonist run in parallel. EC 50 Values were determined by fitting the percent activation as a function of compound concentration using the Hill equation (XLfit).
[0273] The EC50 values of exemplary compounds in the low expression assay are shown in the table below. The EC50 values were compared with reference compound A and reference compound B.

[0274] Example B2: Metabolic stability of hepatocytes Test compounds were incubated with human hepatocytes to assess stability from a stromal depilation approach. Test compounds were dissolved in dimethyl sulfoxide (DMSO) to make 10 mM stock solutions and further diluted to make 1000x 1 mM working stock solutions with DMSO in 96-well plates for test compounds and positive control (midazolam). Vials containing cryopreserved hepatocytes were removed from the liquid nitrogen tank and immediately immersed in a 37°C water bath. The vials were gently shaken until the contents were thawed and then immediately poured into 48 mL of pre-warmed HT medium in a 50 mL conical tube. The cells remaining in the vial were resuspended in 1.0 mL of pre-warmed HT medium and added to the conical tube. The tube was capped and then gently inverted several times to resuspend the hepatocytes. The cell suspension was centrifuged at 50 x g for 5 min at room temperature and the supernatant was discarded. The cell pellet was loosened by gently swirling the tube and resuspended in 4 mL of warm Dulbecco's Modified Eagle Medium (DMEM). Cell density was determined using a Nexcelom cell counter, and DMEM medium was added to obtain a target density of 1 x 106 cells / mL. The assay was performed in 96-well microtiter plates. Test compounds were added at 1 x 10 at 1 μM in DMEM. 6 The mixtures were incubated with 10000 cells / mL hepatocytes for 0, 30, 60, 120 and 240 min. Incubations were performed at 37°C in a humidified atmosphere of 95% air / 5% CO2 with gentle shaking. The volume of the incubation mixture was 37 μL with 0.1% DMSO final. At each time point, the incubation was stopped by adding 150 μL of quenching solution (100% acetonitrile, 0.1% formic acid with bucetin as internal standard for positive ESI mode). The mixtures were then vortexed for 20 min and centrifuged at 4,000 RPM at 10°C. The supernatants (80 μL) were transferred to a clean 96-well plate and analyzed by LC-MS / MS. Midazolam at 1 μM with 0.1% DMSO final was included as a positive control to validate the assay performance. Percentage of parent remaining, intrinsic and predicted hepatic clearance, and t 1 / 2was calculated. All samples were analyzed by LC-MS / MS using an ABSciex API4000 instrument connected to a Shimadzu LC-20ADLC pump system. Separation was achieved using a Waters Atlantis T3d C18 reversed-phase HPLC column (20 mm x 2.1 mm) at a flow rate of 0.5 mL / min. The mobile phase consisted of 0.1% formic acid in water (solvent A) and 0.1% formic acid in 100% acetonitrile (solvent B). The elution conditions are detailed below. [Table 6]
[0275] The ion optics for each test compound were optimized for declustering potential (DP), collection energy (CE), and collision cell exit potential (CXP) and used for selected ion monitoring experiments in positive ion mode. The peak area ratio of each test compound relative to the internal standard was then assessed for stability. The extent of metabolism was calculated based on the disappearance of the test compound compared to the initial concentration. The initial rate of clearance of the test compound was calculated using a linear regression plot of the semi-log % remaining of the compound versus time. The elimination rate constant (k) from the linear regression plot was then used to calculate the t using the following equation: 1 / 2 and inherent clearance (CL int ) was determined, where C 肝細胞 (million cells / mL) is the cell density of the incubation: k=-slope t 1 / 2 =0.693 / k CL int =k / C 肝細胞
[0276] This method of intrinsic clearance measurement assumes that the concentration of the test compound is much lower than the compound's Michaelis-Menten constant for its metabolic enzyme.
[0277] Predicted hepatic clearance (CL hep ) is the normalized CL based on liver weight int(インビボ)The mixture was calculated using the well-stirred method using the following formula: CL int(インビボ) =CL int x Hepatocellular x Liver Weight CL hep予測値 =(CL int(インビボ) ×Q 肝臓 ) / (CL int(インビボ) +Q 肝臓 ) Here, Q 肝臓 (ml / min / kg) is the hepatic blood flow
[0278] Physiological parameters related to human liver weight, blood flow, and hepatocellularity are given below. [Table 7]
[0279] The results are shown in the table below for intrinsic clearance (mL / min / kg) and half-life (t1 / 2). [Table 8]
[0280] Example B3. Passive permeability and flux ratio Caco-2 cells (clone C2BBe1) were obtained from the American Type Culture Collection (Manassas, VA). Cell monolayers were grown to confluence on collagen-coated microporous membranes in 12-well assay plates. Plate and qualification details are as follows: Permeability assay buffer was Hanks' balanced salt solution, pH 7.4, containing 10 mM HEPES and 15 mM glucose. The buffer in the receiver chamber also contained 1% bovine serum albumin. The concentration of the dosing solution was 5 μM of the test substance in assay buffer. Cell monolayers were dosed apically (A-to-B) or basolaterally (B-to-A) and incubated at 37°C with 5% CO2 in a humidified incubator. Samples were taken from the donor and receiver chambers at 120 min. Each measurement was performed in duplicate. To ensure that no damage was done to the cell monolayer during the flux period, the flux of Lucifer Yellow was also measured after the experiment for each monolayer. All samples were analyzed by LC-MS / MS using electrospray ionization. Apparent transmittance (P app ) and the recovery rate were calculated as follows: P app =(dC r / dt) × V r / (A×C A ) (1) Recovery rate = 100 × ((V r ×C r 最終 )+(V d ×C d 最終 )) / (V d ×C N ) (2) In the formula, dC r / dt is the slope of the cumulative receiver concentration versus time (μMs -1 ) and V r is the volume of the receiver compartment (cm 3 ) and V d is the volume of the donor compartment (cm 3 ), and A is the area of the insert (1.13 cm for 12 wells). 2) and C A is the mean of the nominal dose concentration and the measured donor concentration over 120 min (μM), and C N is the nominal concentration of the dosing solution (μM), and C r 最終 is the cumulative receiver concentration at the end of the incubation period (μM), and C d 最終 is the donor concentration (μM) at the end of the incubation period. The efflux ratio (ER) is the ratio of P app (B-to-A) / P app It is defined as (A-to-B). [Table 9]
[0281] Example B4: Pharmacokinetics in rats Intravenous administration: Compounds were formulated at 0.5 mg / mL in a solution containing 5% polyethylene glycol 400 and 95% (12% (w / v) sulfobutyl-β-cyclodextrin in water) (v / v). Formulated compounds were sterile filtered through a 0.22 micron filter prior to administration. Compounds were administered to male 7-11 week old Sprague-Dawley rats via jugular vein cannula injection at a dose of 1 mg / kg over 30 minutes.
[0282] Oral administration: Compounds were formulated at 0.3 mg / mL or 0.6 mg / mL in a solution containing 5% polyethylene glycol 400 and 95% (12% (w / v) sulfobutyl-β-cyclodextrin in water) (v / v). Formulated compounds were administered to male 7-11 week old Sprague-Dawley rats by oral gavage at a dose of 10 mg / kg.
[0283] Sample collection: Approximately 0.2 mL of blood was collected per time point from the jugular vein or other appropriate site of each animal into pre-chilled commercially available EDTA-K2 tubes and placed on wet ice until centrifugation. Blood samples were processed for plasma by centrifugation at 3,200 g for 10 min at approximately 4°C. Plasma was collected, transferred to pre-labeled 96-well plates or polypropylene tubes, flash frozen on dry ice, and stored at or below -60°C until LC-MS / MS analysis.
[0284] Data Analysis: Plasma concentration versus time data were plotted on graphs and analyzed by a non-compartmental approach using the Phoenix WinNonlin 6.3 software program. Relevant PK parameters were calculated according to the route of administration, e.g., CL, V for intravenous administration, and ΔP, V for intravenous administration. dss and C0, and C for extravascular administration. max , T max or %F, T for all routes 1 / 2 , AUC (0-t) , AUC (0-inf) , MRT (0-t) , and MRT (0-inf) was calculated.
