AI Technical Summary
Compounds with low membrane permeability and solubility face challenges in oral absorption, leading to inadequate efficacy and safety evaluations, and often require individualized formulations for each compound, making early-stage drug screening inefficient and prone to overlooking potentially useful candidates.
A compound formulation containing an oily component with a polyoxyethylene structure, where the oily component constitutes 2.0% to 7.5% of the volume, acts as an absorption enhancer and solubility improver, enhancing oral absorption and allowing for standardized evaluation of candidate compounds.
The formulation significantly increases oral absorption of compounds with low solubility and membrane permeability, enabling more effective evaluation of candidate compounds and reducing the risk of overlooking useful candidates as false negatives.
Abstract
Description
Compound preparation containing an oily component containing a polyoxyethylene structure
[0001] The present invention relates to a compound preparation containing an oily component having a polyoxyethylene structure. The present invention also relates to a method for screening candidate compounds using the preparation.
[0002] In general, compounds with a molecular weight of 500 or more have low membrane permeability when orally administered, and are considered to have problems with oral absorption (e.g., Non-Patent Documents 1 and 2). Furthermore, compounds with low solubility and low membrane permeability tend to have low oral absorption. These compounds often fail to achieve sufficient absorption even when the dose is increased, making appropriate efficacy and safety evaluation impossible. For this reason, in pharmaceutical development, the selection of compounds with such properties has been avoided as much as possible during the screening stage.
[0003] On the other hand, when a compound with low oral absorbability is selected as a candidate compound for a pharmaceutical product, efforts have been made to improve oral absorbability by formulation techniques or drug delivery techniques (e.g., Non-Patent Document 3).

[0005] However, the optimal additive and / or formulation may differ for each compound, and in the early stage of screening candidate compounds when there are a large number of test compounds, selecting the optimal additive and / or formulation for each test compound and administering each test compound with a different additive and / or formulation is not realistic, since it would require optimizing different additives and / or formulations for each test compound.
[0006] Furthermore, when oral administration animal testing is performed in the early stages of drug screening, test compounds are evaluated using formulations prepared using certain common additives, but depending on the compatibility between the test compound and the additive, sufficient oral absorption may not be achieved, and the test compound may not be evaluated appropriately. As a result, the screening process for candidate compounds is influenced by chance factors, and there is a possibility that useful test compounds may be overlooked as false negatives.
[0007] The present invention has been made in view of the above circumstances, and aims to provide a versatile formulation with improved oral absorbability that enables evaluation of compounds under the same formulation conditions. Another aim of the present invention is to provide a method for screening candidate compounds using the formulation.

[0064] In the present specification, an amino acid in which the main chain amino group is substituted is referred to as an "N-substituted amino acid." As used herein, the "N-substituted amino acid" is preferably an N-alkyl amino acid, an N-C 1 -C 6 Alkylamino acid, N-C 1 -C 5 Alkylamino acid, N-C 1 -C 4 Alkylamino acid, N-C 1 -C 3 Alkyl amino acids, N-ethyl amino acids, N-methyl amino acids, N-C 7 -C 14 Examples include, but are not limited to, aralkyl amino acids, N-benzyl amino acids, and N-phenethyl amino acids.

[0066] As used herein, "amino acids" include all corresponding isotopes. An isotope of an "amino acid" is one in which at least one atom has been replaced with an atom having the same atomic number (number of protons) but a different mass number (the sum of the number of protons and neutrons) in an abundance ratio different from the natural abundance ratio. Examples of isotopes included in "amino acids" as used herein include hydrogen atoms, carbon atoms, nitrogen atoms, oxygen atoms, phosphorus atoms, sulfur atoms, fluorine atoms, and chlorine atoms, each of which is 2 H. 3 H. 13 C. 14 C. 15 N. 17 O. 18 O. 32 P. 35 S. 18 F. 36 Cl, etc. Compounds herein containing all proportions of radioactive or non-radioactive isotopes are within the scope of the present invention.
[0067] The peptide compound according to this embodiment may contain two or more N-substituted amino acid residues. The number of N-substituted amino acid residues contained in the peptide compound according to this embodiment may be, for example, three or more, four or more, or five or more.
[0068] The peptide compound according to this embodiment may be a peptide compound having a cyclic portion (sometimes referred to herein as a "cyclic peptide compound"). As used herein, the "cyclic portion" of a peptide compound refers to a cyclic portion formed by linking two or more amino acid residues. The number of amino acid residues constituting the cyclic portion of the cyclic peptide compound may be 5 to 15, 6 to 15, 7 to 15, 8 to 15, 9 to 15, 10 to 15, 5 to 14, 6 to 14, 7 to 14, 8 to 14, 9 to 14, 10 to 14, 5 to 13, 6 to 13, 7 to 13, 8 to 13, 9 to 13, 10 to 13, 5 to 12, 6 to 12, 7 to 12, 8 to 12, 9 to 12, 10 to 12, 5 to 11, 6 to 11, 7 to 11, 8 to 11, 9 to 11, 10 to 11, or 11. The cyclic moiety is preferably formed via a covalent bond such as an amide bond, a carbon-carbon bond-forming reaction, an S-S bond, a thioether bond, or a triazole bond, and can be formed by bonding a group at the N-terminus and a group at the C-terminus of a linear peptide compound to which amino acid residues are linked. Specifically, for example, it can be formed by bonding an amino group at the N-terminus and a carboxyl group at the C-terminus of a linear peptide compound to which amino acid residues are linked. The cyclization may be performed in any manner, such as via a carbon-nitrogen bond such as an amide bond, via a carbon-oxygen bond such as an ester bond or an ether bond, via a carbon-sulfur bond such as a thioether bond, via a carbon-carbon bond, via a sulfur-sulfur bond, or via a heterocyclic ring structure. Among these, cyclization via a covalent bond such as an amide bond or a carbon-carbon bond is preferred, and cyclization via an amide bond between a carboxy group in a side chain and an amino group in the main chain is more preferred. The position of the carboxy group and amino group used for cyclization may be on the main chain or on the side chain, and is not particularly limited as long as it is in a position that allows cyclization.
[0069] The cyclic peptide compound according to this embodiment may have 15 to 46 ring atoms. As used herein, the term "number of ring atoms" refers to the number of atoms (ring atoms) in a cyclic compound, including the innermost portion of the ring. When a compound has multiple rings, the term is defined as the number of atoms in the ring with the largest number of atoms. When two rings share some atoms, the ring with the fewer shared atoms is used to calculate the number of ring atoms in each ring. To further explain the "number of ring atoms" using specific examples, for example, using this method, tetrahydrofuran (THF) has 5 ring atoms, tacrolimus (FK506) has 21 ring atoms, and Compound 1 and Compound 9 described in the Examples have 34 ring atoms.
[0070] The number of ring atoms in the cyclic peptide compound according to this embodiment may be, for example, 34 to 46, 34 to 43, 34 to 40, 34 to 37, 34 to 36, or 34. The ring atoms used to calculate the number of ring atoms may be selected from the group consisting of carbon atoms, hydrogen atoms, nitrogen atoms, oxygen atoms, sulfur atoms, phosphorus atoms, and silicon atoms, or may be selected from the group consisting of carbon atoms, hydrogen atoms, nitrogen atoms, and oxygen atoms.
[0071] A peptide compound according to one embodiment may have a ClogP / amino acid residue ratio of 1.0 or greater. Here, "number of amino acid residues" refers to the total number of amino acid residues constituting the peptide compound. For example, a cyclic peptide compound having a cyclic portion consisting of 10 amino acid residues and a linear portion consisting of 1 amino acid residue has 11 amino acid residues. The ClogP / amino acid residue ratio is a value calculated by dividing the ClogP of a peptide compound by the number of amino acid residues contained in the peptide compound. For example, if the ClogP of a peptide compound is 14.0 and the number of amino acid residues contained in the peptide compound is 7, the ClogP / amino acid residue ratio of the peptide compound is calculated to be 2.0.
[0072] The ClogP / number of amino acid residues of the peptide compound according to this embodiment may be, for example, 1.1 or more, or 1.2 or more. The upper limit of the ClogP / number of amino acid residues of the peptide compound according to this embodiment may be, for example, 1.8 or less, 1.7 or less, 1.6 or less, or 1.5 or less. Examples of ranges of the ClogP / number of amino acid residues of the peptide compound according to this embodiment include 1.0 or more and 1.8 or less, 1.0 or more and 1.7 or less, 1.1 or more and 1.6 or less, and 1.1 or more and 1.5 or less.

[0110] In the formulation according to this embodiment, the oily component containing a polyoxyethylene structure can be considered to have the effect of promoting the absorption of the compound, and can be considered an active ingredient capable of promoting the absorption of the compound. Similarly, the oily component containing a polyoxyethylene structure can be considered to have the effect of improving the solubility of the compound, and can be considered an active ingredient capable of improving the solubility of the compound.

[0111] From the above viewpoint, the preparation of this embodiment is preferably that the absorption of compound is promoted compared with the preparation that does not contain the oily component that contains polyoxyethylene structure.In addition, the preparation of this embodiment is preferably that the solubility of compound is improved compared with the preparation that does not contain the oily component that contains polyoxyethylene structure.Here, the "preparation that does not contain the oily component that contains polyoxyethylene structure" to be compared refers to the preparation that has a composition in which the oily component that contains polyoxyethylene structure is replaced with a carrier (for example, water) in the preparation of this embodiment.
[0112] The formulation according to this embodiment has a general purpose, enhanced oral absorption of compounds, and can therefore be suitably used for screening candidate compounds. Candidate compounds include, in particular, pharmaceutical candidate compounds (clinical candidate compounds). A method for screening candidate compounds using the formulation according to this embodiment will now be described.
[0113] [Candidate Compound Screening Method] The candidate compound screening method according to this embodiment (hereinafter also simply referred to as the "screening method") comprises administering the above-described formulation according to the present invention to a subject. In the following description, the compound contained in the formulation may be particularly referred to as the "test compound."
[0114] The screening method according to this embodiment may include selecting a candidate compound using at least one index selected from the group consisting of the following (1), (2), and (3): (1) efficacy, (2) toxicity, and (3) pharmacokinetic properties.
[0115] In the screening method according to this embodiment, the efficacy and / or toxicity of a test compound administered to a subject can be measured, and test compounds with recognized or high efficacy can be selected, or test compounds with low or no toxicity can be selected. The efficacy and / or toxicity of a test compound can be evaluated, for example, by comparing it with a preset threshold value. Alternatively, similar measurements can be performed using a compound with efficacy as a control, and test compounds with higher efficacy or lower toxicity than the control can be selected. Examples of efficacy include, but are not limited to, cell proliferation inhibition, cytotoxicity, and tumor growth inhibition. Examples of toxicity include, but are not limited to, hepatotoxicity, nephrotoxicity, and cardiotoxicity.
[0116] Furthermore, in the screening method according to this embodiment, the pharmacokinetic properties of a test compound can also be evaluated by measuring the blood concentration of the test compound in a subject administered with the test compound. Here, "pharmacokinetic properties" refers to properties such as the effective blood concentration, blood half-life, and / or elimination rate of the test compound in the subject's body. The pharmacokinetic properties of a test compound may be evaluated, for example, by comparison with a preset threshold value. For example, a substance with a higher effective blood concentration, a longer blood half-life, or a slower elimination rate is generally considered to have better pharmacokinetic properties, but this is not a limitation. Furthermore, the method for measuring the blood concentration of a test compound is not particularly limited.
[0117] The screening method according to this embodiment may include (3) selecting a candidate compound using pharmacokinetic properties as an index.
[0118] The screening method according to this embodiment may select a candidate compound from a plurality of test compounds. In this case, each of the plurality of test compounds is administered to a subject as a separate formulation. The number of test compounds is not particularly limited, and may be, for example, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, or 8 or more. Note that since screening involves selecting compounds that meet certain conditions, the screening method according to this embodiment can also be performed on a single test compound.
[0119] In the screening method according to this embodiment, the subject to which the formulation according to the present invention is administered is not particularly limited, and may be a non-human animal. Examples of the subject include dogs, monkeys, minipigs, rabbits, rats, and mice. Rats and mice are preferred, and mice are more preferred.
[0120] In the screening method according to this embodiment, the method of administering the formulation according to the present invention is not particularly limited, and may be orally or parenterally. However, the formulation according to the present invention is preferably administered orally because the oral absorbability of the compound is enhanced.
[0121] In the screening method according to this embodiment, the dosage of the formulation according to the present invention is not particularly limited, and may be administered so that the dose of the test compound per kg of subject body weight (kg) is 0.1 mg / kg to 1000 mg / kg. The dose of the test compound may be, for example, 1 mg / kg to 500 mg / kg, 1 mg / kg to 100 mg / kg, 1 mg / kg to 50 mg / kg, 3 mg / kg to 30 mg / kg, 10 mg / kg to 30 mg / kg, 0.1 mg / kg to 10 mg / kg, 1 mg / kg to 5 mg / kg, 10 mg / kg to 100 mg / kg, 15 mg / kg to 50 mg / kg, 20 mg / kg to 40 mg / kg, 25 mg / kg to 35 mg / kg, 3 mg / kg, or 30 mg / kg.
[0122] [Method for comparing test compounds] The method according to this embodiment is a method for comparing a plurality of test compounds, and includes administering the above-described formulation according to the present invention to a subject, and comparing the plurality of test compounds using at least one index selected from the group consisting of the following (1), (2), and (3): (1) efficacy, (2) toxicity, and (3) pharmacokinetic properties.
[0123] In the comparison method according to this embodiment, the efficacy and / or toxicity of test compounds administered to a subject are measured and compared between test compounds. This allows, for example, the selection of test compounds with relatively high efficacy or relatively low toxicity. Alternatively, similar measurements can be performed using a control compound with efficacy as the test compound to select test compounds with higher efficacy or lower toxicity compared to the control. Examples of efficacy include, but are not limited to, cell proliferation inhibitory activity, cytotoxic activity, and tumor growth inhibitory activity. Examples of toxicity include, but are not limited to, hepatotoxicity, nephrotoxicity, and cardiotoxicity.
[0124] Furthermore, in the comparison method according to this embodiment, the pharmacokinetic properties of a test compound can be evaluated by measuring the blood concentration of the test compound in a subject administered the test compound. Here, "pharmacokinetic properties" refers to the concentration of the test compound in the subject's body, preferably characteristics such as the effective blood concentration, blood half-life, and / or elimination rate of the test compound in the subject's body. By comparing the pharmacokinetic properties of test compounds, test compounds with relatively superior pharmacokinetic properties can be selected. Alternatively, similar measurements can be performed using a control compound with pharmacological activity as the test compound to select test compounds with superior pharmacokinetic properties compared to the control. For example, generally, the higher the effective blood concentration, the longer the blood half-life, or the slower the elimination rate, the better the pharmacokinetic properties of the substance, but this is not a limitation. Furthermore, the method for measuring the blood concentration of the test compound is not particularly limited.
[0125] The comparison method according to this embodiment may include (3) comparing test compounds using pharmacokinetic properties as an index. The number of test compounds is not particularly limited, and may be, for example, two or more, or three or more.
[0126] In the comparative method according to this embodiment, the subject to which the formulation according to the present invention is administered is not particularly limited, and may be a non-human animal. Examples of the subject include dogs, monkeys, minipigs, rabbits, rats, and mice. Rats and mice are preferred, and mice are more preferred.
[0127] In the comparative method according to this embodiment, the method of administering the formulation according to the present invention is not particularly limited, and may be orally or parenterally. On the other hand, the formulation according to the present invention is preferably administered orally because the oral absorption of the compound is enhanced.
[0128] In the comparative method according to this embodiment, the dosage of the formulation according to the present invention is not particularly limited, and may be administered so that the dose of the test compound per kg of subject body weight (kg) is 0.1 mg / kg to 1000 mg / kg. The dose of the test compound may be, for example, 1 mg / kg to 500 mg / kg, 1 mg / kg to 100 mg / kg, 1 mg / kg to 50 mg / kg, 3 mg / kg to 30 mg / kg, 10 mg / kg to 30 mg / kg, 0.1 mg / kg to 10 mg / kg, 1 mg / kg to 5 mg / kg, 10 mg / kg to 100 mg / kg, 15 mg / kg to 50 mg / kg, 20 mg / kg to 40 mg / kg, 25 mg / kg to 35 mg / kg, 3 mg / kg, or 30 mg / kg.
[0129] [Method for enhancing systemic absorption of a test compound] The method according to this embodiment is a method for enhancing systemic absorption of a test compound in a subject, and includes administering the above-described formulation according to the present invention to the subject. The systemic absorption may be gastrointestinal absorption. The formulation according to the present invention has excellent oral absorption of the compound, and therefore can be suitably used in a method for enhancing systemic absorption of a test compound in a subject.

Cremophor EL (CreEL) (Sigma-Aldrich, "Kolliphor EL"; generic name: polyoxyethylene castor oil, average number of moles of ethylene oxide added: 35), Vitamin E TPGS (Sigma-Aldrich), an aqueous solution containing 1% TW80 (Nacalai Tesque), an aqueous solution containing 1.5% Ploxamer 188 (BASF), or an aqueous solution containing 0.5% Triton X-100 were added to the compound powder. The mixture was stirred with a stirrer (room temperature, 20 hours), filtered, and the compound concentration of the filtrate was measured by LC / UV. Solubility (μg / mL) was calculated from the measured compound concentration. The results are shown in Table 7. Compounds 1 and 2 were confirmed to have greater solubility in the presence of surfactants than in the absence of surfactants. In particular, greater solubility was observed in the presence of CreEL or VitaminE TPGS than in the presence of other surfactants (Table 7). This confirms that the use of CreEL or VitaminE TPGS shows excellent solubility improvement independent of the compound, compared to when no surfactant is used or when other surfactants are used. Based on the above, CreEL and VitaminE TPGS were selected as substrates that improve solubility independent of the compound, and oral absorbability was evaluated.

[0186] (Example 2-2) Preparation of Formulations Example formulations (1) and (2) were prepared by mixing and stirring compounds 1 and 2, water for injection (Otsuka Pharmaceutical Factory, Inc.), dimethyl sulfoxide (DMSO) (Wako Pure Chemical Industries, Ltd.), and Cremophor EL to obtain the compositions shown in Table 8. Compounds 1 and 2 were dissolved in dimethyl sulfoxide to a concentration of 3 mg / mL before mixing.
[0187] Comparative preparations (1-1) to (2-2) were prepared by mixing and stirring Compounds 1 and 2, water for injection (Otsuka Pharmaceutical Factory, Inc.), dimethyl sulfoxide (Wako Pure Chemical Industries, Ltd.), and Vitamin E TPGS (Sigma-Aldrich) to the compositions shown in Table 8. Compounds 1 and 2 were dissolved in dimethyl sulfoxide to a concentration of 3 mg / mL before mixing.

[0189] (Example 2-3) Rat PK Study (3 mg / kg) The blood kinetics of Example Formulations (1) and (2) and Comparative Formulations (1-1), (1-2), (2-1), and (2-2) after oral administration to rats was evaluated. Male rats (WIST, 7 weeks old, manufactured by Japan Institute of Medical Science Animal Materials: 4 rats per group) were orally administered either Example Formulations (1) and (2) or Comparative Formulations (1-1), (1-2), (2-1), or (2-2) at a dose of 3 mg / kg of Compound 1, and blood samples were collected over time from the jugular vein using a syringe treated with heparin as an anticoagulant up to 24 hours after administration. Plasma was separated from the blood by centrifugation, and after deproteinization with acetonitrile, the plasma concentrations of Compounds 1 and 2 were measured using an LC / MS / MS system. From the obtained plasma concentration time courses, pharmacokinetic parameters were calculated by non-compartmental analysis using the analytical software Phoenix WinNonlin 8.2 (Certara L.P.). The results are shown in Table 9.
[0190] Pharmacokinetic parameters were calculated as the area under the plasma drug concentration-time curve (AUClast; ng h / mL) from time 0 after administration to the final time point at which a concentration exceeding the limit of quantitation was obtained, and the maximum plasma concentration after administration (Cmax; ng / mL). For Compounds 1 and 2, the AUClast values for the groups administered with Example Formulations (1) and (2) were all greater than the AUClast values for the groups administered with Comparative Formulations (1-1), (1-2), (2-1), and (2-2), and an increase in Cmax was also observed (Table 9). These results demonstrate that the use of Cremophor EL results in higher absorbability of low-membrane-permeable compounds compared to when Cremophor EL is not used.

[0192] [Example 3] Evaluation of physical properties of cyclic peptide compounds (Example 3-1) Evaluation of Caco-2 membrane permeability Caco-2 cells were cultured on a 96-well transwell for 3 weeks, after which DMEM + FaSSIF (1% DMSO) + compound was added to the apical side and DMEM was added to the basal side. 2 Pre-incubation was carried out for 18 to 24 hours at 37°C with shaking at 80 rpm. After pre-incubation, the pre-incubation solution on the apical and basal sides was removed by aspiration and washed. FaSSIF / HBSS buffer (1% DMSO) (pH 6.0) containing the compound was added to the apical side, and HBSS buffer (4% BSA) (pH 7.4) was added to the basal side, and measurement of membrane permeability was then initiated. Each well was incubated at 5% CO 2 The tubes were shaken at 37°C and 80 rpm, and 180 minutes after the start of shaking, a sample was taken from the basal side, and the permeation amount was measured by LC / MS. The membrane permeability coefficient (Papp) was calculated from the permeation amount. Note that the term "Caco-2 (cm / sec)" in the columns of the tables in this specification is used synonymously with "Papp (cm / sec)."
[0193] Caco-2 values of cyclic peptide compounds
[0194] (Example 3-2) Evaluation of Lipid Solubility of Cyclic Peptide Compounds The ClogP values of Compounds 1 to 10 are as follows.
[0195] (Example 3-3) Evaluation of Solubility of Cyclic Peptide Compounds The solubility of cyclic peptide compounds was evaluated. 50 mM phosphate buffer (PPB, pH 6.5) was added to the lyophilized compound powder, and the mixture was shaken (37°C, 1800 rpm, 22 to 24 hours). After filtration, the compound concentration of the filtrate was measured by LC / MS / MS. The solubility was calculated from the measured compound concentration. The solubilities of compounds 3, 4, 6, 7, and 8 were 11 μg / mL, 1 μg / mL, 1 μg / mL, 15 μg / mL, and 5 μg / mL, respectively. These results confirmed that the cyclic peptide compounds exhibited uniformly low solubility.
[0196] The solubility of cyclic peptide compounds in the presence of surfactants was evaluated. Aqueous solutions containing 0.3% or 1% Cremophor EL (CreEL) were added to lyophilized compound powders, followed by shaking (25°C, 1000 rpm, 22-24 hours), filtration, and measurement of the compound concentration in the filtrate by LC / UV. Solubility (μg / mL) was calculated from the measured compound concentration. The results are shown in Table 12. All cyclic peptide compounds exhibited a solubility of 100 μg / mL or more in aqueous CreEL solutions. These results confirmed that the use of CreEL improved the solubility of low-membrane-permeable compounds compared to when no surfactant was used.

[0220] [Example 5] PK Study (Example 5-1) Mouse PK Study (30 mg / kg) The blood kinetics of the Example Formulation and the Comparative Formulation after oral administration in mice were evaluated. Male mice (C57BL / 6J, 7-11 weeks old, manufactured by SiBeiFu Laboratory Animal Technology Co. Ltd. or Charles River Japan, Inc.; 3 mice per group) were orally administered one of the prepared Example Formulations or Comparative Formulations at a dose of 30 mg / kg of Compounds 3-10. Blood samples were collected over time from the jugular vein and posterior vena cava, or from the dorsal pedicle vein and heart using heparin as an anticoagulant up to 24 hours after administration. Plasma was separated from the blood by centrifugation, and the plasma concentrations of Compounds 3-10 were measured using an LC / MS / MS system after deproteinization with acetonitrile or liquid-liquid extraction with ethyl acetate. From the obtained plasma concentration time courses, pharmacokinetic parameters were calculated by non-compartmental analysis using the analytical software Phoenix WinNonlin 8.2 (Certara LP). The results are shown in Tables 34 to 42.
[0221] Pharmacokinetic parameters were calculated as the area under the plasma drug concentration-time curve (AUClast; ng h / mL) from 0 hours after administration to the final time point at which a concentration exceeding the limit of quantitation was obtained, and the maximum plasma concentration after administration (Cmax; ng / mL). The AUClast ratio was calculated as the ratio (comparator AUC) of the example formulation or comparative formulation to the AUClast (maximum AUC) of the example formulation that showed the maximum AUClast upon administration of the same compound within the same test (comparator AUC / maximum AUC). In the cyclic peptide compound group, it was confirmed that the AUClast of the example formulation administration group was greater than the AUClast of the comparative formulation administration group (AUClast ratio of 0.8 or more), and an increase in Cmax was also observed. As shown in Figure 1, it was confirmed that for all compounds, by using a Cremophor EL formulation in which the Cremophor EL content based on 100% by volume of the formulation was 2.0% to 7.5% by volume, the low membrane permeability compounds exhibited higher absorbability (AUClast ratio of 0.8 or greater) compared to the cases in which a Cremophor EL content based on 100% by volume of the formulation was less than 2.0% by volume or more than 7.5% by volume.

[0231] Table 43 shows the percentage (%) of plots with an AUClast ratio of 0.8 or more relative to the total number of plots for each Cremophor EL concentration.
[0232] As shown in Table 43, when the Cremophor EL concentration was greater than 7.5% by volume, the probability of an AUClast ratio of 0.8 or greater was 14%, and when the Cremophor EL concentration was less than 2% by volume, the probability of an AUClast ratio of 0.8 or greater was 0%, whereas when the Cremophor EL concentration was 2.0 to 7.5% by volume, the percentage of AUClast ratios of 0.8 or greater improved to 100%. In other words, it was confirmed that by using 2.0 to 7.5% by volume of Cremophor EL in a cyclic peptide compound, a compound with low membrane permeability exhibited higher absorbability (AUClast ratio of 0.8 or greater) compared to when Cremophor EL concentrations of less than 2.0% by volume and greater than 7.5% by volume were used.
[0233] (Example 5-2) Mouse PK study (3 mg / kg) The blood kinetics of the Example formulation and the Comparative formulation after oral administration in mice were evaluated. Male mice (C57BL / 6, 10 weeks old, manufactured by SiBeiFu Laboratory Animal Technology Co. Ltd. or Charles River Japan, Inc.; 3 mice per group) were orally administered one of the prepared Example formulations or Comparative formulations at a dose of 3 mg / kg of Compounds 3, 4, and 6-10. Blood samples were collected over time from the jugular vein and posterior vena cava, or from the dorsal pedicle vein and heart using heparin as an anticoagulant up to 24 hours after administration. Plasma was separated from the blood by centrifugation, and the plasma concentrations of Compounds 3, 4, and 6-10 were measured using an LC / MS / MS system after deproteinization with acetonitrile or liquid-liquid extraction with ethyl acetate. From the obtained plasma concentration time courses, pharmacokinetic parameters were calculated by non-compartmental analysis using the analytical software Phoenix WinNonlin 8.2 (Certara LP). The results are shown in Tables 44 to 56.
[0234] Pharmacokinetic parameters were calculated as the area under the plasma drug concentration-time curve (AUClast; ng h / mL) from 0 hours after administration to the final time point at which a concentration exceeding the limit of quantitation was obtained, and the maximum plasma concentration after administration (Cmax; ng / mL). The AUClast ratio was calculated as the ratio (comparator AUC) of the example formulation or comparative formulation to the AUClast (maximum AUC) of the example formulation that showed the maximum AUClast when the same compound was administered in the same test (comparator AUC / maximum AUC). In the cyclic peptide compound group, it was confirmed that the AUClast of the example formulation administration group was more likely to be greater than the AUClast of the comparative formulation administration group (AUClast ratio of 0.7 or more), and an increase in Cmax was also observed. As shown in Figure 2, for all compounds, it was confirmed that the use of 2.0 vol% to 7.5 vol% Cremophor EL resulted in high absorbability (AUClast ratio of 0.7 or greater) for compounds with low membrane permeability compared to the use of Cremophor EL concentrations less than 2.0 vol% and greater than 7.5 vol%.

[0248] Table 57 shows the percentage (%) of plots with an AUClast ratio of 0.7 or more relative to the total number of plots for each Cremophor EL concentration.
[0249] As shown in Table 57, at a dose of 3 mg / kg, for example, when the Cremophor EL concentration was greater than 7.5 vol%, the probability of an AUClast ratio of 0.7 or greater was 0%, while when the Cremophor EL concentration was less than 2.0 vol%, the probability of an AUClast ratio of 0.7 or greater was 42%. However, when the Cremophor EL concentration was 2.0 to 7.5 vol%, the proportion of cases with an AUClast ratio of 0.7 or greater improved to 86%. In other words, it was confirmed that the use of 2.0 to 7.5 vol% Cremophor EL in a cyclic peptide compound exhibited higher absorbability (AUClast ratio of 0.7 or greater) compared to when Cremophor EL concentrations of less than 2.0 vol% and greater than 7.5 vol% were used.
[0250] Based on the above results, screening for oral absorption at a specific Cremophor EL concentration can achieve high oral absorption and high plasma concentrations (AUC and Cmax). In other words, it is possible to increase the oral absorption of compounds with poor oral absorption, a barrier to drug discovery, according to their potential. This reduces the dropout rate due to false negatives and allows for screening of compounds with excellent oral absorption, enabling the selection of optimal compounds. Furthermore, achieving high oral absorption and high plasma concentrations allows for precise evaluation of various compound characteristics essential for drug development, such as oral bioavailability, pharmacological activity upon oral administration, safety upon oral administration, pharmacokinetics upon oral administration, and compound physical properties, enabling better drug development decisions.
