Description

[Technical field]

[0001] The present disclosure relates to amino lipid compounds that can be used to prepare lipid nanoparticles for delivering active ingredients, and methods for preparing the same. The present disclosure also relates to compositions, particularly lipid nanoparticles, comprising said amino lipid compounds, and uses thereof. [Background technology]

[0002] Gene therapy drugs introduce genes with specific genetic information into target cells by artificial means, and the expressed target proteins exert regulatory, therapeutic, and even curative effects on diseases caused by congenital or acquired gene defects, or the gene series interferes with or regulates the expression of related genes to exert clinical therapeutic effects. However, gene therapy drugs still face several challenges, such as the difficulty of directly introducing nucleic acids into cells and the fact that they are highly susceptible to degradation by nucleases in the cytoplasm. Therefore, in order to facilitate the achievement of the therapeutic and / or preventive purposes of gene therapy drugs, it is necessary to develop more amino lipid compounds that can be used to deliver nucleic acids as active ingredients, as well as related preparation methods and applications.

For example, a range of "1-10" should be understood to include not only the values ​​1 and 10 explicitly mentioned, but also the individual values ​​(e.g., 2, 3, 4, 5, 6, 7, 8, and 9) and subranges (e.g., 1-2, 1.5-2.5, 1-3, 1.5-3.5, 2.5-4, 3-4.5, etc.) within the range of 1-10. This principle also applies to ranges that use only one value as a minimum or maximum value.

[0029] As used herein, the term "isomers" refers to different compounds that have the same molecular formula. "Stereoisomers" are isomers that differ only in the arrangement of atoms in space. "Atropisomers" are stereoisomers that result from hindered rotation about a single bond. "Enantiomers" are a pair of stereoisomers that are non-superimposable mirror images of each other. A mixture of a pair of enantiomers in any ratio may be called a "racemic" mixture. "Diastereoisomers" are stereoisomers that have at least two asymmetric atoms and are not mirror images of each other. "Tautomers" are isomers of a compound that are in equilibrium with each other. The concentration of an isomer depends on the environment in which the compound is found, for example, whether the compound is a solid, in an organic solution, or in an aqueous solution.

[0030] In certain embodiments, "stereoisomer" also includes E isomers, Z isomers, or mixtures thereof, cis isomers, trans isomers, or mixtures thereof.

[0031] The nucleic acids and / or polynucleotides useful in the present disclosure include a coding region encoding a polypeptide of interest, a 5'-UTR at the 5'-end of the coding region, and a 3'-UTR at the 3'-end of the coding region. In some embodiments, the nucleic acid or polynucleotide further includes at least one of a polyadenylation region and a Kozak sequence. In some embodiments, the nucleic acid or polynucleotide (e.g., mRNA) may include a 5' cap structure. Any region of the nucleic acid may include one or more alternative nucleosides, such as 5-substituted uridine (e.g., 5-methoxyuridine), 1-substituted pseudouridine (e.g., 1-methyl-pseudouridine or 1-ethyl-pseudouridine), and / or 5-substituted cytidine (e.g., 5-methyl-cytidine).

[0032] The term "5'-UTR" or "5'-untranslated region" can be an RNA sequence in an mRNA that is located upstream of a coding sequence and is not translated into a protein. The 5'-UTR of a gene typically begins at a transcription initiation site and ends at a nucleotide upstream of the translation initiation codon of the coding sequence. The 5'-UTR can contain elements that control gene expression, such as a ribosome binding site, a 5' terminal oligopyrimidine tract, and a translation initiation signal, such as a Kozak sequence. An mRNA can be post-transcriptionally modified by the addition of a 5' cap. Thus, the 5'-UTR in a mature mRNA can also refer to the RNA sequence between the 5' cap and the initiation codon. As used herein, the term "3' untranslated region" or "3'-UTR" can be an RNA sequence in an mRNA that is located upstream of a coding sequence and is not translated into a protein. The 3'-UTR in an mRNA is located between the stop codon of the coding sequence and the poly(A) sequence, for example, beginning at a nucleotide downstream of the stop codon and ending at a nucleotide upstream of the poly(A) sequence. The sequences of the 5'-UTR and / or 3'-UTR may be homologous or heterologous to the sequence of the coding region. The 3'-UTR may consist of a 3'-UTR derived from at least one of the following genes: albumin gene, α-globin gene, β-globin gene, tyrosine hydroxylase gene, lipoxygenase gene, and collagen α gene.

[0033] In the present specification, the terms "polyadenylation region", "poly(A) sequence" and "poly(A) tail" are used interchangeably. Naturally occurring poly(A) sequences are typically composed of adenine ribonucleotides. Preferably, "polyadenylation region" refers to a poly(A) sequence that includes nucleotides or nucleotide segments other than adenine ribonucleotides. Poly(A) sequences are usually located at the 3' end of an mRNA, for example, at the 3' end (downstream) of the 3'-UTR. The length of the polyA region may vary. In particular, in some embodiments, the length of the polyA region of the nucleic acid molecule of the present disclosure is at least 30 nucleotides; in some embodiments, the length of the polyA region of the nucleic acid molecule of the present disclosure is at least 80 nucleotides; in some embodiments, the length of the polyA region of the nucleic acid molecule of the present disclosure is at least 100 nucleotides.

[0034] As used herein, the term "5' cap structure" refers to a 5' cap structure typically located at the 5' end of a mature mRNA. In some embodiments, the 5' cap structure is linked to the 5' end of an mRNA with a 5'-5'-triphosphate bond. The 5' cap structure is typically formed from modified (e.g., methylated) ribonucleotides (especially from guanine nucleotide derivatives). For example, m7GpppN (cap 0, or "cap 0" is a cap structure formed by the 5'-phosphate group of hnRNA interacting with the 5'-phosphate group of m7GTP under the action of guanylate transferase to form a 5',5'-phosphodiester bond), where N is the terminal 5' nucleotide of the nucleic acid having the 5'-cap structure. In some embodiments, the 5' cap structure includes, but is not limited to, cap 0, cap 1 (a cap structure formed from cap 0 by further methylating the 2'-OH of the ribose on the first nucleotide of an hnRNA, or "cap 1"), cap 2 (a cap structure formed from cap 1 by further methylating the 2'-OH of the ribose on the second nucleotide of an hnRNA, or "cap 2"), cap 4, a cap 0 analog, a cap 1 analog, a cap 2 analog, or a cap 4 analog.

[0078] All of the amino lipid compounds of the present disclosure have hydrophobic properties due to the presence of long non-polar residues, and at the same time hydrophilic properties due to the amino groups. Due to this amphiphilic property, the amino lipid compounds of the present disclosure can be used to form lipid nanoparticles such as lipid bilayers, micelles, and liposomes.

[0079] In the context of the present disclosure, the term "lipid nanoparticles" refers to nanometer-sized materials produced by introducing amino lipid compounds into an aqueous solution. The particles are in particular lipid nanoparticles, lipid bilayer vesicles (liposomes), multilamellar vesicles or micelles.

[0080] In some preferred embodiments, the lipid nanoparticles are liposomes comprising the amino lipid compounds of the present disclosure. Within the scope of the present disclosure, liposomes are small microparticles consisting of a bilayer of lipid amphiphilic molecules encapsulating an aqueous compartment.

[0081] The formation of liposomes is not a spontaneous process. When lipids are introduced into water, lipid vesicles first form, which then form a bilayer or a series of bilayers, each separated by water molecules. Liposomes are formed by sonicating lipid vesicles in water.

[0082] In the context of this disclosure, the term "lipid bilayer" refers to a thin film formed by two layers of lipid molecules. The term "micelle" refers to an aggregate of surfactant molecules dispersed in a liquid colloid. Typical micelles in aqueous solutions form aggregates upon contact with water with hydrophilic head regions that chelate the hydrophobic single tail region in the center of the micelle.

[0083] In one aspect, the present disclosure provides the use of the amino lipid compounds of the present disclosure for the manufacture of a vehicle for an active ingredient.

[0378] Experimental Example 1: Preparation of lipid nanoparticles encapsulating luciferase mRNA (Fluc mRNA) (1) Mixture: Predetermined amounts of Fluc mRNA stock solution, 0.2 M sodium acetate buffer, and DEPC water were added to a container and mixed well to obtain an aqueous phase; The amino lipid compound of the present disclosure, the helper lipid, the structural lipid, and the PEG lipid were dissolved separately in absolute ethanol to prepare solutions with concentrations of 20 mg / mL, 10 mg / mL, 20 mg / mL, and 25 mg / mL, respectively. The above four solutions were pipetted in a lipid:DSPC:CHO-HP:M-DMG-2000 molar ratio of 48:10:40.5:1.5 and mixed well to prepare an alcohol phase.

[0379] (2) Encapsulation: Using a microfluidic preparation device (MPE-L2), the above aqueous phase and the above alcohol phase were injected into a microfluidic chip at a flow rate of aqueous phase:alcohol phase = 12 mL / min:4 mL / min, and encapsulation was performed at a flow rate of aqueous phase:alcohol phase = 9 mL / min:3 mL / min to obtain mRNA-encapsulated lipid nanoparticles (mRNA-LNPs).

[0381] (4) The product of step (3) was sterilized by passing it through a 0.22 μm microporous membrane and packaged. A lipid nanoparticle formulation encapsulating Fluc mRNA was prepared with a Fluc mRNA concentration of 0.2 μg / μL, a Fluc mRNA to lipid mass ratio of 1:10, a particle diameter of 80-130 nm, and an encapsulation efficiency of 85% or more.

[0382] Experimental Example 2: Evaluation of in vivo delivery performance of lipid nanoparticles Animal preparation: 6-8 week-old female BALB / c mice were selected and bred in an SPF grade breeding room. Animal experiments were carried out in strict compliance with the guidelines of the national medical institution and the requirements of animal ethics.

[0383] In vivo delivery: Before injecting the test LNP formulation, the LNP formulation was gently inverted repeatedly to thoroughly mix the compounded sample. The corresponding amount of formulation sample was aspirated into a 1 ml insulin syringe, and the LNP formulation was injected via tail vein injection (IV) into three mice in duplicate per formulation. Each mouse was injected with 75 μL of the luciferase mRNA (Fluc mRNA)-encapsulated lipid nanoparticle formulation prepared in Experimental Example 1.

[0384] Six hours after injection of the LNP formulation, the mice were injected with 200 μL of D-Luciferin luciferase expression substrate (catalog no. 122799; manufacturer: Perkin Elmer). After substrate injection, the mice were anesthetized with isoflurane inhalation, and the injection time of the luciferase expression substrate was recorded. Ten minutes after substrate injection, the animals were placed in a supine position, and the signal distribution and expression intensity of luciferase in the animal's body and in various organs were observed using an In Vivo Imaging System (IVIS).

[0385] Table 4 shows the encapsulation efficiency of representative amino lipid compounds in lipid nanoparticles encapsulating luciferase mRNA (Fluc mRNA) and the fluorescence expression intensity induced thereby, using amino lipid compound 118 as a control.

[0388] [Table 5]

[0389] As can be seen from Table 5, all amino lipid compounds except amino lipid compounds 108 and 109 showed a stronger preference for delivery to the spleen compared to amino lipid compound 118.

[0390] Experimental Example 3: Evaluation of delivery performance of lipid nanoparticles to lymph nodes Animal preparation: 6-8 week-old female BALB / c mice were selected and bred in an SPF grade breeding room. Animal experiments were carried out in strict compliance with the guidelines of the national medical institution and the requirements of animal ethics.

[0391] In vivo delivery: Before injecting the test LNP formulation, the LNP formulation was gently inverted repeatedly to thoroughly mix the prepared sample. A corresponding amount of the formulation sample was drawn into a 1 ml insulin syringe, and the LNP formulation was injected into three mice per formulation via tail vein injection (IV). Each mouse was injected with 75 μL of the luciferase mRNA (Fluc mRNA)-encapsulated lipid nanoparticle formulation prepared in Experimental Example 1.

[0392] Six hours after injection of the LNP formulation, the mice were injected with 200 μL of D-Luciferin luciferase expression substrate (catalog no. 122799; manufacturer: Perkin Elmer). After substrate injection, the mice were anesthetized with isoflurane inhalation, and the injection time of the luciferase expression substrate was recorded. Ten minutes after substrate injection, the animals were placed in a supine position, and the signal distribution and expression intensity of luciferase in the lymph nodes were observed using an In Vivo Imaging System (IVIS).

[0393] Table 6 shows the fluorescence expression intensity induced by lipid nanoparticles in which luciferase mRNA (Fluc mRNA) was encapsulated with a representative amino lipid compound, using SM-102 as a control.

[0394] [Table 6]

[0395] As can be seen from Table 6, amino lipid compounds 250 and 268 are more effective at delivering to lymph nodes than SM102, indicating a stronger preference for lymph nodes.

[0396] Experimental Example 4: In vivo safety evaluation of lipid nanoparticles Following the method described in Experimental Example 1, luciferase mRNA (Fluc mRNA) was replaced with human erythropoietin mRNA (hEPO mRNA), and a human erythropoietin mRNA (hEPO mRNA)-encapsulated lipid nanoparticle formulation was prepared with an hEPO mRNA concentration of 0.2 μg / μL, a hEPO mRNA to lipid mass ratio of 1:10, a particle diameter of 90 to 130 nm, and an encapsulation efficiency of 90% or more.

[0397] Animal preparation: 6-8 week-old female BALB / c mice were selected and bred in an SPF grade breeding room. Animal experiments were carried out in strict compliance with the guidelines of the national medical institution and the requirements of animal ethics.

[0398] In vivo delivery: Prior to injection of the test LNP formulations, the LNP formulations were gently inverted repeatedly to thoroughly mix the compounded samples. A corresponding amount of formulation sample was drawn into a 1 ml insulin syringe and the LNP formulations were injected IV into five mice per formulation via the tail vein. Each mouse was injected with 300 μL of the human erythropoietin mRNA (hEPO mRNA)-encapsulated lipid nanoparticle formulation.

[0399] Collection of serum: 12 hours after injection, blood was collected from the mice and placed in a tube without anticoagulant. Blood was allowed to clot naturally at room temperature for 30-60 minutes, and then centrifuged at 3500 rpm for 10 minutes to obtain the supernatant, which was used as serum.

[0400] Alanine transaminase was detected according to the kit (Nanjing Jiancheng Bioengineering Institute, Catalog No. C009-2-1) instructions, and a standard curve was constructed using the standard provided with the kit. D-PBS was used in the experiment, which was purchased from Sangon Biotech (Shanghai) Co., Ltd. (Cat. No. E607009-0600).

[0401] The method for detecting the enzyme activity of alanine aminotransferase (ALT) in mouse serum is as follows:

[0402] Preparation of ALT standard curve: (1) Enzyme reaction: 0, 2, 4, 6, 8, and 10 μL of 2 μmol / mL sodium pyruvate standard solution were added to 5 μL of 0.1 mol / L phosphate buffer solution in sequence, and the matrix solution was added to make up to 25 μL. The mixture was then mixed well by repeatedly aspirating and dispensing with a pipette;

[0403] (2) Addition reaction: 20 μL of 2,4-dinitrophenylhydrazine solution was added to all reaction wells in (1), mixed by aspirating and dispensing, and then placed in a 37° C. incubator for reaction for 20 minutes;

[0404] (3) Development: 200 μL of 0.4 mol / L NaOH solution was added to all reaction wells in (2) to stop the reaction, mixed by aspirating and dispensing, and incubated at room temperature for 15 minutes. The OD value of each well was measured at 510 nm with a microplate reader; and

[0405] (4) Data processing of the standard curve: The absolute OD value of each well was calculated by subtracting the OD value of the 0 μL well from the OD measurement value of each well, and the corresponding ALT Karmen units were set to 0, 28, 57, 97, 150, and 200 U / L, respectively. The standard curve was obtained by plotting the absolute OD value on the horizontal axis and the corresponding Carmen unit on the vertical axis.

[0406] Detection of ALT enzyme activity in serum samples: (1) Preparation of reagents: The ALT matrix solution was placed in a 37°C incubator and preheated; (2) Enzyme reaction: 5 μL of diluted serum was aspirated and added to a 96-well plate, and 20 μL of matrix solution was added to the corresponding sample wells, mixed by repeatedly aspirating and dispensing to avoid air bubbles, and then placed in a 37°C incubator for 30 minutes; (3) Addition reaction: 20 μL of 2,4-dinitrophenylhydrazine was added to all reaction wells in (2), mixed by aspirating and dispensing, and then reacted in a 37° C. incubator for 20 minutes; (4) Development: 200 μL of 0.4 mol / L NaOH solution was added to all reaction wells in (3) to stop the reaction, and the wells were mixed by aspirating and dispensing, and then incubated at room temperature for 15 minutes. The OD value of each well was measured at a wavelength of 510 nm using a microplate reader; and (5) Calculation of ALT enzyme activity in serum: The absolute OD value of the corresponding sample well was calculated by subtracting the OD value of the control well from the OD value of the sample well obtained, and the ALT enzyme activity (Carmen units) of the corresponding serum sample was calculated by substituting it into the standard curve equation.

[0407] Figure 1 shows the results of in vivo safety evaluation of lipid nanoparticles encapsulating human erythropoietin (hEPO) mRNA using representative amino lipid compounds, with ALC00315 and SM-102 as controls.

[0408] As can be seen from Figure 1, compared with commercially available ALC0315 and SM-102, the representative amino lipid compounds showed equivalent or lower ALT enzyme activity (Carmen units), and 252, 255, 259, 260, 263, 264, 266, 267, 270, 272, and 273 had significantly lower ALT enzyme activity (Carmen units) and were therefore safer.

[0409] Experimental Example 5: IFN-γ Elispot Cellular Immunoassay Following the method described in Experimental Example 1, luciferase mRNA (Fluc mRNA) was replaced with IN002.5.1 mRNA, and an IN002.5.1 mRNA-encapsulated lipid nanoparticle formulation was prepared with an IN002.5.1 mRNA concentration of 0.2 μg / μL, an IN002.5.1 mRNA to lipid mass ratio of 1:10, a particle diameter of 80 to 130 nm, and an encapsulation efficiency of 90% or more.

[0410] The sequence of IN002.5.1 mRNA is that in SEQ ID NO. 1, all uracils (u) are replaced by N1-methylpseudouridine. It is noteworthy that the t (thymine) in the RNA sequence of the sequence listing, SEQ ID NO. 1, is actually u (uracil) according to the WIPO Standard ST.26 for Nucleotide or Amino Acid Sequence Listings.

[0411] Animal preparation: 6-8 week-old female BALB / c mice were selected and bred in an SPF grade breeding room. Animal experiments were carried out in strict compliance with the guidelines of the national medical institution and the requirements of animal ethics.

[0412] Immunization of mice: Prior to injection of the test LNP formulation, the LNP formulation was gently inverted repeatedly to thoroughly mix the compounded sample. A corresponding amount of the formulation sample was drawn into a 1 ml insulin syringe and the LNP formulation was injected intramuscularly (IM) in the tail into 8 mice per formulation. Each mouse was injected with 50 μL of the IN002.5.1 mRNA-loaded lipid nanoparticle formulation.

[0413] Spleen collection: On day 7 after immunization, 3 to 4 mice were selected from each LNP immunization group, euthanized, and the spleens were collected in a super clean bench.

[0414] Collection of serum: On the 14th day after immunization, 150 μL of orbital blood was collected from five mice in each LNP-immunized group, placed in a tube without anticoagulant, allowed to clot naturally at room temperature for 30 to 60 minutes, and then centrifuged at 3,500 rpm for 10 minutes, and the supernatant was used as serum.

[0415] ELISpot test for mouse lymphocytes: Isolation of lymphocytes: Mouse spleens were removed on a super clean bench. 7 mL of mouse lymphocyte separation solution was added to a 6-well cell culture plate. Mouse spleen cells were crushed with a syringe piston, and the spleen cell suspension was filtered through a cell screen and immediately transferred to a 15 mL centrifuge tube. 1000 μL of RPMI1640 medium was slowly added while distinguishing the liquid interface. After centrifugation at 800 g for 30 minutes at room temperature in a horizontal rotor, obvious stratification was observed. The lymphocyte layer was aspirated, 10 mL of RPMI1640 medium was added, and the tube was inverted to wash. The cells were collected by centrifugation at 250 g for 10 minutes at room temperature, and red blood cells were lysed. After red blood cell lysis was completed, the supernatant was poured off, the cells were suspended in the medium, and counted.

[0416] Addition of stimuli and culture of lymphocytes: Precoated plates were activated with RPMI-1640 medium containing 10% fetal bovine serum. After at least 30 min at room temperature, the medium was removed and the cell suspension with adjusted concentration was added (100 μL / well). The medium used to resuspend the cells was used as background negative control. 10 μL of positive stimuli working solution (PMA+ionomycin (dissolved in DPBS)) was added to positive control wells; 10 μL of medium used to resuspend the cells was added to negative control wells; and 10 μL / well of peptide library diluted in RPMI1640 was added to experimental wells. After addition of all samples and stimuli, the plates were covered and incubated in an incubator at 37°C with 5% CO2 for 16-24 h.

[0417] ELISPOT detection after incubation: The cells and culture medium in the wells were discarded, and the wells were lysed with 200 μL / well of ice-cold deionized water at 4°C for 10 minutes. The liquid in the wells was shaken and washed five times with PBS buffer. The wells were incubated with 100 μL / well of 1 μg / ml detection antibody at room temperature for 2 hours; after washing the plate five times with PBS, the wells were incubated with 100 μL / well of 1000-fold diluted enzyme-labeled avidin (Streptavidin-HRP) at room temperature for 1 hour. After washing the plate five times with PBS, it was incubated with TMB substrate developer equilibrated to room temperature in the dark for 15 minutes at room temperature. The developer was discarded, and the front, back and base of the plate were washed 3 to 5 times with deionized water to stop the development.

[0418] Spot counting of ELISPOT plates: The plates were placed in a cool and dark place at room temperature, and the bottom was closed after air drying. The plates were read by an enzyme-linked immunospot analyzer, and various parameters of the spots were recorded.

[0419] The results of IFN-γ ELISPOT cellular immunoassay using lipid nanoparticles in which IN002.5.1 mRNA was encapsulated with a representative amino lipid compound are shown in Figures 2, 3 and 4, with ALC0315 as a control.
