Description

[Technical Field]

[0001] The present invention relates to lipid compounds that deliver active substances into cells in vivo, and lipid nanoparticle compositions containing said lipid compounds. [Background technology]

[0002] In recent years, the COVID-19 pandemic emergency and the continued emergence of new virus variants have led to rapid development of mRNA vaccine technology, which allows for faster development and greater versatility than traditional vaccines. mRNA vaccines have been the subject of intensive research over the past decade, and in addition to SARS-CoV-2, they are being studied for influenza, Zika virus, rabies, respiratory syncytial virus (RSV), cytomegalovirus (CMV), and cancer vaccines. Unlike traditional vaccines that contain pathogens (such as viruses), mRNA vaccines contain only mRNA, which carries the genetic information of the virus, making them significantly safer (non-infectious).

[0003] COVID-19 mRNA vaccines primarily contain mRNA encoding the spike protein found on the surface of SARS-CoV-2. Once administered, mRNA is delivered to the cytoplasm of cells, where it expresses the spike protein. This protein then functions as an antigen, leading to the production of antibodies against the virus. Because mRNA vaccines can be manufactured by modifying the mRNA base sequence according to the virus's genetic information, vaccine development and production speeds are extremely fast, making them effective at responding to virus variants. This makes mRNA vaccines more versatile and flexible than conventional vaccines, offering advantages in terms of speed of production and cost.

[0004] However, mRNA is structurally very fragile and can be easily destroyed by enzymes such as RNase (ribonuclease), and genetic information can be damaged depending on the storage environment. Therefore, a delivery vehicle is essential that fully protects the mRNA structure to maximize vaccine efficacy, and improves mRNA delivery to the cytoplasm through high intracellular delivery efficiency and smooth endosomal escape. Known mRNA delivery vehicles include viral vectors and lipid nanoparticles (LNPs). However, viral vectors have concerns about immune responses and long-term toxicity, as well as limitations on the size of the mRNA they can contain. Therefore, lipid nanoparticles (LNPs) are attracting attention as the most promising delivery vehicle.

[0005] In particular, the recent COVID-19 pandemic has led to a growing demand for next-generation LNP delivery vehicles that improve the structural stability of mRNA and the stability of LNPs containing it, as well as the efficacy and safety of vaccines, and even enable targeting to specific tissues (sites) within the body. To this end, research into the development of new lipid compounds and LNP compositions containing them is actively underway worldwide.

[0068] Figure 1 shows an example of the structure of mRNA-LNP and the conventional lipid compound structures that make it up. Referring to Figure 1, lipid nanoparticle (LNP) delivery vehicles generally consist of four lipid compounds surrounding an active substance: (A) cationic lipids or ionizable lipids that exhibit cationic properties in a (weakly) acidic environment; (B) phospholipids that form the outermost layer of the LNP; (C) cholesterol (structural lipids) that fill the voids within the LNP and increase its rigidity; and (D) PEGylated lipids (PEG (poly(ethyleneglycol))-lipids; PEG-lipids) that are distributed primarily on the surface of the LNP, contribute to stabilizing the LNP structure, and increase its solubility in water. Here, the ionizable lipids interact with the active substance in a (weakly) acidic environment, immobilizing it by surrounding its surface. The active substance may include siRNA, shRNA, rRNA, tRNA, mRNA, miRNA, saRNA, circRNA, DNA, cDNA, plasmid, DNAzyme, ribozyme, PNA, aptamer, antisense oligonucleotide, CRISPR, protein, carbohydrate, drug, etc.

[0069] FIG. 2 shows the binding mode between a lipid compound and mRNA according to one embodiment of the present invention.

[0070] 2, conventional lipid compounds have a cationizable tertiary amine at the center, a hydrophobic lipid tail, and a polar head group (e.g., a hydroxy group), whereas the lipid compounds of the present invention further contain an additional interactive group (yellow star).

[0071] In one embodiment of the lipid compound, the tertiary amine moiety may exhibit cationic properties in a (weakly) acidic environment, forming an attractive force between it and the anionic moiety of the active substance. In this case, the additional interactive group may form an additional interaction with another moiety of the active substance. The additional interaction may be a non-covalent bond such as hydrogen bonding or π-π interaction.

[0072] In other words, attractive forces such as electrostatic interactions, hydrogen bonds, and π-π interactions are formed between the lipid compound and the active substance, thereby increasing the stability between the lipid compound and the active substance and the stability of the lipid nanoparticles (LNPs) containing them.

[0073] The present invention provides a lipid compound represented by the following Chemical Formula 1, an isomer thereof, or a salt thereof:

[0527] Example 27. mRNA-LNP production

[0528] Ionizable lipids prepared according to Examples 1 to 29 above or commercially available (Compound 1-178, SM-102 (Broadpharm, USA; Patent Document 3 [PCT / US2016 / 052352 (BENENARO, KE; KUMARASINGHE, ES; CORNEBISE, M.) 2016.09.16]), ALC-0315 (Broadpharm, USA; Patent Document 4 [PCT / US2016 / 029572 (TAM, Y.; HOPE, MJ; WEISSMAN, D.; PARDI, N.) 2016.04.27]), DLin-MC3-DMA (MC3; Broadpharm, USA; Patent Document 5 [US2010 / 0324120 A1 (JIANXIN, C. et al.) 2016.04.27]), etc.) were used. [2010.12.23.], etc.), phospholipids (e.g., DSPC; Sigma-Aldrich, USA), cholesterol (Sigma-Aldrich, USA), and PEGylated lipids (e.g., ALC-0159 (Broadpharm, USA; Patent Document 6 [PCT / US2015 / 034496 (ANSELL, SM; DU, X) 2015.06.05]), DMG-PEG (DMG-PEG2000; Sigma-Aldrich, USA), etc.) were dissolved in the organic phase (ethanol). 5-100 μg of mRNA (e.g., firefly luciferase mRNA (fLuc mRNA), enhanced green fluorescent protein mRNA (EGFP mRNA), SARS-CoV-2 spike mRNA, TriLink Biotechnologies, USA) was diluted in 0.2-2.0 mL of 5-50 mM acetic acid aqueous solution.

[0529] An aqueous phase was prepared.

[0530] mRNA-lipid nanoparticles (LNPs) were prepared by mixing an organic phase (ethanol) containing ionizable lipids, phospholipids, cholesterol, and PEGylated lipids with an aqueous phase (sodium acetate or sodium citrate solution) containing mRNA at an average flow rate of 25-250 μL / 10 s using a microfluidic mixer (NanoAssemblr® Spark, Precision Nanosystems, Canada). Specifically, the constituent lipid compounds were dissolved in ethanol in a molar ratio of (20-60):(0-25):(30-60):(0-5) (ionizable lipid:phospholipid:cholesterol:PEGylated lipid), where the total ratio was 100 and the weight ratio of ionizable lipid:mRNA was (4-30):1. To remove ethanol from the mRNA-encapsulated lipid nanoparticles and adjust the pH of the lipid nanoparticle solution to match in vivo pH (~7.4), the nanoparticles were dialyzed against phosphate-buffered saline (PBS, pH 7.4, Invitrogen, USA) for several times over 12-18 hours using a dialysis cassette (Slide-A-Lyzer Dialysis Cassette, 10K MWCO, ThermoFisher, USA).

[0531] Hereinafter, lipid nanoparticle compositions are referred to according to the type of ionizable lipid used in the preparation of mRNA-LNPs.

[0532] The numbers in the figures or tables refer to the compound numbers of the examples used in the production of mRNA-LNP. For example, "16" in Figure 3 refers to mRNA-LNP produced using compound 16, and is referred to as "Composition 16." Experimental Examples

[0533] Experimental Example 1. pK of mRNA-LNP a measurement

[0534] Apparent pK of mRNA-LNP prepared in Example 27 awas measured by analysis using 6-(p-toluidino)-2-naphthalenesulfonic acid sodium salt (TNS; Sigma-Aldrich, USA).

[0535] Anionic TNS generally does not exhibit fluorescence in aqueous solution, but as the pH decreases, the content of positively charged ionizable lipids increases, and TNS interacts electrostatically with these lipids, moving to the hydrophobic domain (lipophilic), and exhibiting increasingly strong fluorescence. When the pH of the solution increases and the ionizable lipids are neutralized, they are no longer able to interact electrostatically with TNS, losing their lipophilicity and detaching from the hydrophobic domain, resulting in quenching of TNS fluorescence. Based on this principle, the change in TNS fluorescence intensity due to changes in ambient pH can be plotted as an S-shaped curve, and the log value of the inflection point can be calculated to determine the pK of lipid nanoparticles. a Usually, the pK a Lipid nanoparticles with a pH value of 6.0-7.0 have a surface charge close to zero in plasma (pH ~ 7.4) upon intravascular injection, which reduces the likelihood of binding to body tissues and increases the rate of delivery to liver cells. Once inside the cells, they become highly charged within the endosomes (pH 5.5), facilitating the endosomal escape of the active substances to be delivered, such as genes, proteins, and synthetic drugs, resulting in excellent in vivo drug delivery efficiency (Non-Patent Document 1 [Sabnis, S. et al. Mol. Ther. 2018, 26, 1509], Non-Patent Document 2 [Jayaraman, M. et al. Angew. Chem. Int. Ed. 2012, 51, 8529]).

[0536] Specifically, a master buffer solution containing 10 mM sodium phosphate, 10 mM sodium borate, 10 mM sodium citrate, and 150 mM sodium chloride (NaCl) was prepared. The pH was then adjusted to various pH values ​​from 2.5 to 12 using 1 M sodium hydroxide (NaOH) and 1 M hydrochloric acid (HCl). A 150 or 300 μM TNS standard stock solution was then prepared by dissolving it in DMSO. LNPs were prepared at mRNA concentrations of 0.02–0.08 mg / mL in 1X PBS buffer or 20 mM tris(hydroxymethyl)aminomethane (Tris) buffer containing 8% sucrose. 90–94 μL of each solution at each pH was placed in triplicate in a black-bottomed 96-well plate (n=3). Each well was filled with 3.26-4.00 μL of lipid nanoparticles and 2 μL of TNS solution. After careful mixing, the fluorescence intensity of each well was measured using a multiplate reader (Cary Eclipse, Agilent Technologies, USA) at λex 330 nm and λem 435 nm. The measurement results are shown in Figure 3.

[0537] FIG. 3 shows the apparent pK of mRNA-LNP prepared in Example 27 by TNS binding assay. a The results of the measurements are shown in the graph.

[0538] Specifically, compositions 16, 17, 19, and 33 to 40 were selected from the mRNA-LNPs prepared in Example 27, and pK a The above-mentioned Compositions 16, 17, 19, and 33 to 40 were produced under their respective optimal formulation conditions, and the optimal formulation conditions were determined based on known conditions in reports from the institutions that developed ionizable lipids.

[0539] pK of the mRNA-LNP a The measurement results are shown in Table 2 below, along with the optimal formulation conditions for each.

[0540] Referring to Figure 3 and Table 2, the pKa values ​​of the mRNA-LNPs prepared in the examples are all between 6.0 and 7.0, which suggests that their drug delivery efficiency in vivo is appropriate.

[0541] It was also confirmed that the pKa values ​​were similar to those of mRNA-LNPs produced using commercially available ionizable lipids, SM-102 and MC3.

[0542] [Table 2]

[0543] Experimental Example 2. Measurement of size, polydispersity, and surface charge of mRNA-LNP

[0544] Each mRNA-LNP prepared in Example 27 was diluted with PBS to a concentration of 1 μg / mL of mRNA, and the size, polydispersity index (PDI), and surface charge of the mRNA-LNP were measured using a Malvern Zetasizer Nano ZS90 (Malvern Instruments, UK).

[0545] For particles administered to the systemic circulatory system, such as blood vessels, they must be smaller than 200 nm in size in order to pass through the endothelium capillaries of the liver. Only a small PDI of 0.3 or less can be considered to have a uniform particle size distribution, and consistent and efficient efficacy can be expected (Non-Patent Document 3 [Danaei, M. et al. Pharmaceutics 2018, 10, 57]).

[0546] Figure 4 is a graph showing the results of measuring the hydrodynamic diameter and polydispersity index (PDI) of the mRNA-LNP prepared in Example 27, and Figure 5 is a graph showing the results of measuring the surface charge of the mRNA-LNP prepared in Example 27. The measurement results are summarized in Table 2.

[0547] Referring to Figures 4 and 5 and Table 2, the measured sizes of the mRNA-LNPs were all within the appropriate range of 200 nm or less, and the PDI was 0.2 or less, which means that all were considered to be highly uniform.

[0548] Experimental Example 3. Measurement of mRNA encapsulation efficiency

[0549] The mRNA encapsulation efficiency (EE, %) of the mRNA-containing LNPs was measured using a RiboGreen RNA analysis kit (Quant-iT RiboGreen® RNA, Invitrogen).

[0550] The lipid nanoparticles prepared in Example 27 were diluted to 50 μL with 1X TE (Tris-EDTA) buffer or 1X TE buffer containing 2% Triton-X 100 to a final mRNA concentration of 20-30 ng / mL and added to each well of a 96-well plate. 50 μL of 1X TE buffer was added to the group without Triton-X 100 (Group A), and 50 μL of 1X TE buffer containing 2% Triton-X 100 was added to the group with Triton-X 100 (Group B). The lipid nanoparticles were incubated at 37°C for 10 minutes to decompose with Triton-X 100 and release the mRNA contained therein. Then, 100 μL of RiboGreen reagent was added to each well. The fluorescence intensity of Groups A and B was measured using a multiplate reader (λex 480 nm, λem 520 nm), and the mRNA encapsulation efficiency (%) was calculated using the following equation: The mRNA encapsulation efficiency (%) for each lipid nanoparticle was calculated as the average of two repeated measurements. The measurement results are summarized in Table 2.

[0551] As summarized in Table 2, the encapsulation efficiency of all mRNA-LNPs was confirmed to be around 90%, confirming that mRNA was encapsulated with a fairly high efficiency.

[0552] [Number 1]

[0553] mRNA encapsulation efficiency (%) = [(fluorescence intensity of group B - fluorescence intensity of group A) / (fluorescence intensity of group B)] x 100

[0554] Experimental Example 4. Evaluation of protein expression efficiency of EGFP mRNA-LNP administered to cells

[0555] LNPs containing EGFP mRNA encapsulated using various ionizable lipids prepared by the method of Example 27 were administered to HeLa cells (ATCC, USA) to compare in vitro protein expression efficiency (related to transfection, endosomal escape, mRNA stability, etc.) over time. EGFP mRNA-LNPs prepared using the ionizable lipids MC3 or SM-102 were used as controls.

[0556] The remaining lipid compounds constituting the LNPs were cholesterol, the PEG-lipid was DMG-PEG, and the phospholipid was DSPC, but 1 mol% of the total phospholipids was sulfo-cyanine 5.5-DSPE for tracking the LNPs under a fluorescence microscope.

[0557] Specifically, 18 hours before administration of mRNA-LNP, 1 × 10 HeLa cells were plated in an 8-well plate. 5After seeding at a density of 100 cells / well, the cells were cultured in DMEM medium (Gibco, USA) containing FBS and antibiotics at 37°C and 5% CO2. The concentration of mRNA-LNP administered was adjusted to 100 ng / well based on mRNA, and the cells were treated with the medium at 5, 10, 15, 30 minutes, 1 hour, 3 hours, 6 hours, 24 hours, and 48 hours. After each treatment, the medium was removed and the cells were fixed with 4% PFA for 15 minutes, and then images were taken using a fluorescence microscope.

[0558] Experimental Example 5. Evaluation of protein expression efficiency of fLuc mRNA-LNP administered by intramuscular injection (im) and intravenous injection (iv)

[0559] All of the following animal experiments were conducted with the approval of the Animal Experiment Ethics Committee at the Korea Institute of Bioscience and Biotechnology.

[0560] The fLuc mRNA-LNPs prepared using various ionizable lipids, as prepared by the method of Example 27, were administered intramuscularly (i.m.) or intravenously (i.v.) to compare their in vivo protein expression efficiency. EGFP mRNA-LNPs prepared using commercially available ionizable lipids MC3 or SM-102 were used as controls. All mRNA-LNPs were injected at an equivalent weight-based dose (n ≥ 4) for each concentration.

[0561] Specifically, the mRNA-LNPs were administered intramuscularly or intravenously to 6-10-week-old female C57BL / 6 mice (Orient Bio) at a dose of 0.1-0.5 mg / kg body weight of fLuc mRNA. Subsequently, 10 min before imaging, 200 μL (15 mg / mL) of luciferin was intraperitoneally injected to confirm protein expression at 1, 3, 6, 24, 48, and 72 h postinjection. Whole-body luminescence images were then acquired using an in vivo imaging system (IVIS) Lumina III (PerkinElmer, Waltham, MA) under respiratory anesthesia with 3% isoflurane and 97% medical oxygen. The acquired luminescence images were quantitatively analyzed using imaging software (Living Image Software Version 4.4; PerkinElmer, USA).

[0562] Figure 6 shows whole-body images of a mouse intramuscularly injected with fLuc mRNA-LNP prepared in Example 27 of the present invention, taken at various time points after administration using an imaging device (IVIS Lumina III) designed specifically for small animals.

[0563] Figure 7 shows the results of quantitative analysis of the luminescence images obtained in the experiment in Figure 6. After intramuscular injection of the prepared fLuc mRNA-LNP into mice, the luminescence intensity at the injection site was measured at various time points. The measured values ​​are summarized in Table 3 below.

[0564] [Table 3] TIFF2025540651000062.tif70170

[0565] Referring to Figures 6, 7 and Table 3, all of the mRNA-LNPs prepared in Example 27 successfully expressed proteins in vivo.

[0566] In addition, luminescence intensity at the injection site was measured 3 hours after intramuscular injection, and protein expression rates were calculated in comparison with control MC3- or SM-102-based LNPs. The analysis results of protein expression rates are summarized in Table 4 below.

[0567] [Table 4]

[0568] Referring to Table 4, among the measured mRNA-LNPs, most mRNA-LNPs, except for compositions 18, 33, 37, and 40, showed higher protein expression than the control group MC3 at 3 hours after injection, and compositions 17 and 21, which had the best effects, showed significantly higher protein expression than the control group SM-102 at 3 hours after injection.

[0569] Experimental Example 6. Optimization of mRNA-LNP formulation

[0570] We attempted to optimize the composition ratio between mRNA and lipid compounds constituting fLuc mRNA-LNPs prepared using various ionizable lipids 1-178 prepared by the method of Example 27.

[0571] Specifically, formulation optimization was performed by adjusting the molar ratio (based on moles) between the four constituent lipid compounds of LNP (ionizable lipid:phospholipid:cholesterol:PEGylated lipid) in the range of (20-60):(0-25):(30-60):(0-5), and by adjusting the N / P ratio (number of ionizable nitrogen atoms in the ionizable lipid:number of phosphorus atoms in the phosphate group that indicates anionicity in the mRNA) in the range of 1.5-15. Specifically, fLuc mRNA-LNPs containing each ionizable lipid were prepared in more than 15 different formulations according to the same systematic method. Each mRNA-LNP was then intramuscularly injected into mice as described in Experimental Example 5, and luminescence images were acquired and analyzed using an IVIS system over a period of time. The optimal formulation conditions (composition ratio and N / P ratio) for each ionizable lipid and the mRNA-LNPs containing it were determined to yield the highest protein expression rate. The optimal composition ratio and N / P ratio for each ionizable lipid are shown in Table 2.

[0572] Experimental Example 7. Evaluation of endosomal escape efficiency of EGFP mRNA-LNP administered to cells

[0573] LNPs containing EGFP mRNA encapsulated using various ionizable lipids prepared by the method of Example 27 were administered to cells, and the efficiency of mRNA release from endosomes to the cytoplasm of the mRNA-LNPs that entered the cells was compared. EGFP mRNA-LNPs prepared using the ionizable lipids MC3 or SM-102 were used as controls.

[0574] The remaining lipid compounds comprising the LNPs were cholesterol, DMG-PEG as the PEG-lipid, and DSPC as the phospholipid. 0.1 mol% of the total lipids (i.e., if the phospholipid content is 10 mol% of the total lipids, this corresponds to 1 mol% of the total phospholipids) was sulfo-cyanine 5.5-DSPE or ATTO 647N DOPE (Sigma-Aldrich, USA) for tracking the LNPs under a fluorescence microscope.

[0575] Specifically, 18 hours before administration of mRNA-LNP, 1 × 10 HeLa cells (ATCC, USA) were plated in an 8-well plate. 5 After seeding at a density of 100 cells / well, the cells were cultured in DMEM medium (Gibco, USA) containing FBS and antibiotics at 37°C and 5% CO2. As a control, cells injected with unformulated EGFP mRNA into the cytoplasm by electrical stimulation were also seeded in other wells for comparison. The dose of mRNA-LNP administered was adjusted to 100 ng / well based on mRNA, and the HeLa cells were treated. After 4 hours, the cells were fixed with 4% PFA and photographed under a fluorescence microscope.

[0576] Meanwhile, to quantitatively measure the number of cytoplasmic mRNA molecules, the cells were treated with smFISH and imaged under a microscope after a certain period of time. The endosomal escape efficiency was compared and analyzed for each ionizable lipid component as the ratio (R / L) of the number of cytoplasmic mRNAs (R) to the number of LNPs that entered the cell (L). To confirm the fluorescence intensity-based analysis results, we used a co-staining method with the endocytic markers EEA1 (early endosomes) and Lamp1 (lysosomes).

[0577] Experimental Example 8: Verification of in vitro immunogenicity of SARS-CoV-2 spike mRNA-LNP

[0578] SARS-CoV-2 mRNA-encapsulated LNPs prepared using various ionizable lipids, as prepared by the method described in Example 27, were applied to cells to analyze the mRNA levels of inflammation-related factors (CCL2, CCL3, IL-1β, and IL-6). Specifically, HEK-293T cells were treated with LNPs at 1 μg / well of mRNA. After 24 hours, cells were lysed using Trizol (Thermo Fisher, #15596026), then chloroform was added and incubated for 2-3 minutes. The cells were then centrifuged at 12,000 g for 15 minutes at 4°C, and the aqueous layer containing the RNA was transferred to a new tube. Isopropanol was added, incubated at 4°C for 10 minutes, and then centrifuged at 12,000 g for 15 minutes at 4°C. The supernatant was discarded, and the pellet was washed with 75% ethanol. The sample was mixed using a vortex mixer and centrifuged at 7,500 g for 5 minutes at 4°C. After discarding the supernatant, resuspend the pellet in 2-50 μL of RNase-free water. The extracted RNA was reverse-transcribed using a cDNA synthesis kit (Toyobo, #FSK-101) and amplified using RT-qPCR (Dice TP800 thermal real-time PCR system) with SFC green qPCR master mix (SFC, #pgm1005). All measurements were normalized to the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) housekeeping gene. Each experiment was performed three times per condition, and measurements were performed twice (n=6). The gene-specific primer sequences are as follows:

[0599] Experimental Example 9. In vivo toxicity evaluations

[0600] The fLuc mRNA-LNP prepared by the method of Example 27 was administered intramuscularly (im) to the living body, and the toxicity of the LNP was evaluated through serum biochemistry analysis.

[0601] At 24 and 48 hours after intravenous injection, 50-100 μL of serum was collected from each mouse by retro-orbital blood collection. Serum biochemistry analyses were performed using a Hitachi 7150 Chemistry Analyzer to measure liver function indicators: aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP), as well as kidney function indicators: blood urea nitrogen (BUN) and creatinine.

[0602] Figure 9 shows the results of analyzing five toxicity indicators for the liver, kidneys, etc. by collecting blood samples after a certain period of time has elapsed since the mRNA-LNP prepared in Example 27 was injected into the body.

[0603] As shown in Figure 9, Composition 17 showed similar ALP and BUN values ​​to the controls PBS and SM-102, and showed lower AST toxicity than the controls PBS and SM-102, confirming its excellent safety.

[0604] Experimental Example 10. Stability measurement of mRNA-LNP depending on storage temperature and period

[0605] The fLuc mRNA-LNPs prepared using various ionizable lipids according to the method of Example 27 were stored at constant temperatures of 4°C and 25°C, and the size, polydispersity index (PDI), and encapsulation efficiency (EE) of the mRNA-LNPs were measured using the methods of Experimental Examples 2 and 3 at 1 day, 3 days, and 30 days after preparation.

[0606] 10 is a graph showing the size, polydispersity, and encapsulation efficiency of LNP samples measured according to the time elapsed since preparation and temperature conditions of mRNA-LNP prepared in Example 27. The analytical results are summarized in Table 6 below.

[0607] Referring to Figure 10 and Table 6, even after 30 days, the size, polydispersity, and encapsulation efficiency of the LNPs remained stable without any significant changes at storage temperatures of 4°C and 25°C.
