Docket No. 084284.00356FURAN-DERIVED LIPID NANOPARTICLES FOR TRANSPORTING mRNA TO THE CENTRAL NERVOUS SYSTEMCROSS REFERENCE TO RELATED APPLICATION
[0001] The application claims the benefit of priority under 35 U. S. C. § 119(e) to U. S.Provisional Application No. 63 / 776,373, filed March 24, 2025, the entire disclosure of which is incorporated by reference herein.FIELD
[0002] The present disclosure relates in general to formulations of lipid nanoparticles. The disclosure relates in particular to intracellular delivery of messenger RNA to the central nervous system.BACKGROUND
[0003] Messenger RNA (mRNA) has been applied to many therapeutic fields such as vaccines, cancer immunotherapies, and protein replacement therapies. However, effective delivery of mRNA to the brain continues to be a major challenge. Previously, different routes of administration have been studied for drug delivery to the brain, such as intraparenchymal, intrathecal, intranasal, and systemic administrations. Intraparenchymal injection is currently employed in clinical trials because it directly delivers therapeutics to diseased sites. But this approach is highly invasive. Less invasive than intraparenchymal injection, intrathecal administration provides a direct route for transporting therapeutic agents to the cerebrospinal fluid (CSF) and then to the central nervous system (CNS).
[0004] However, repeated dosing via the intrathecal route often reduces patient compliance. The intranasal route presents a non-invasive alternative to bypass the blood-brainDocket No. 084284.00356barrier (BBB). For example, mRNA-loaded cationic liposomes have been delivered into some regions of the brain by intranasal administration, such as the cortex, striatum, and midbrain. However, this method is challenged by delivery efficiency due to nasal passage conditions and potential drug entrapment within the olfactory mucosa. Lastly, intravenous injection is currently the most clinically used administration route and is suitable for repeated dosing. However, the limited permeability of the BBB may result in suboptimal CNS delivery efficiency.
[0005] Given the foregoing, there is still an urgent need to develop innovative strategies to achieve potent delivery to the brain. This document describes compositions and methods that address some or all of the problems described above.SUMMARY

[0051] The following discussion omits or only briefly describes conventional features of the disclosed technology that are apparent to those skilled in the art. Reference to various embodiments does not limit the scope of the claims attached hereto. Additionally, any examplesDocket No. 084284.00356set forth in this specification are intended to be non-limiting and merely set forth some of the many possible embodiments for the appended claims. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations. A person of ordinary skill in the art would know how to make and use the disclosed technology, in combination with routine experiments, to achieve other outcomes not specifically disclosed in the examples or the embodiments.
[0052] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosure pertains. Although any methods and materials similar or equivalent to those described herein can be used in the practice for testing of the present disclosure, the preferred materials and methods are described herein. In describing and claiming the present disclosure, the following terminology will be used. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
[0053] The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element. Thus, recitation of “a cell”, for example, includes a plurality of cells of the same type. Furthermore, to the extent that the terms “including”, “includes”, “having”, “has”, “with”, or variants thereof are used in either the detailed description and / or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”
[0054] ‘About” as used herein when referring to a measurable value such as an amount, a temporal duration, and the like, is meant to encompass variations of + / - 20%, + / - 10%, + / - 5%, + / -1%, or + / - 0.1% from the specified value, as such variations are appropriate to perform the disclosed methods. Alternatively, particularly with respect to biological systems or processes, theDocket No. 084284.00356term can mean within an order of magnitude within 5-fold, and also within 2-fold, of a value. Where particular values are described in the application and claims, unless otherwise stated the term “about” meaning within an acceptable error range for the particular value should be assumed.
[0055] As used herein, the terms “agent” or “therapeutic agent” are meant to encompass any molecule, chemical entity, composition, drug, therapeutic agent, chemotherapeutic agent, or biological agent capable of preventing, ameliorating, or treating a disease or other medical condition. The term includes small molecule compounds, antisense reagents, mRNA, siRNA reagents, antibodies, antibody fragments bearing epitope recognition sites, such as Fab, Fab’, F(ab’)2 fragments, Fv fragments, single chain antibodies, antibody mimetics (such as DARPins, affibody molecules, affilins, affitins, anticalins, avimers, fynomers, Kunitz domain peptides and monobodies), peptoids, aptamers; hormones, oligonucleotides, enzymes, peptides organic or inorganic molecules, natural or synthetic compounds and the like. An agent can be assayed in accordance with the methods of the disclosure at any stage during clinical trials, during pre-trial testing, or following FDA-approval.
[0056] As used herein, the terms “comprising,” “comprise” or “comprised,” and variations thereof, in reference to defined or described elements of an item, composition, apparatus, method, process, system, etc. are meant to be inclusive or open-ended, permitting additional elements, thereby indicating that the defined or described item, composition, apparatus, method, process, system, etc. include those specified elements— or, as appropriate, equivalents thereof— and that other elements can be included and still fall within the scope / definition of the defined item, composition, apparatus, method, process, system, etc.
[0057] An “effective amount” as used herein, means an amount that provides a therapeutic or prophylactic benefit.Docket No. 084284.00356
[0058] The term “encapsulation efficiency” as used herein refers to the percentage of nucleic acid in the lipid nanoparticles that is not degraded after exposure to serum or a nuclease assay that would significantly degrade free nucleic acids. As used herein, “encapsulation” may refer to complete, substantial, or partial enclosure, confinement, surrounding, or encasement.
[0059] The term “fully encapsulated” as used herein indicates that the mRNA in the nanoparticles is not significantly degraded after exposure to serum or a nuclease assay that would significantly degrade free nucleic acids. In a fully encapsulated system, preferably less than 25% of particle nucleic acid is degraded in a treatment that would normally degrade 100% of free nucleic acid, more preferably less than 10%, and most preferably less than 5% of the particle nucleic acid is degraded. Fully encapsulated also indicates that the particles are serum stable, that is, that they do not rapidly decompose into their component parts upon in vivo administration.
[0060] As used herein, the term “in vitro” refers to events that occur in an artificial environment, e.g., in a test tube or reaction vessel, in cell culture, in a Petri dish, etc., rather than within an organism (e.g., animal, plant, or microbe).
[0061] As used herein, the term “in vivo” refers to events that occur within an organism (e.g., animal, plant, or microbe or cell or tissue thereof).
[0062] The term “lipid nanoparticle” refers to a nanoparticle that includes lipids and that is stable and dispersible in aqueous media. As used herein, the term “nanoparticle” refers to a particle having one or a plurality of components, the particle having any one structural feature on a scale of less than about 1000 nm that exhibits novel properties as compared to a bulk sample of the same material or component materials. Routinely, nanoparticles have any one structural feature on a scale of less than about 500 nm, less than about 400 nm, less than about 300 nm, less than about 200 nm, or less than about 100 nm. In exemplary embodiments, a nanoparticle is a particleDocket No. 084284.00356having one or more dimensions of the order of about 10 nm to about 500 nm. In other exemplary embodiments, a nanoparticle is a particle having one or more dimensions of the order of about 10 nm to about 1000 nm. A spherical nanoparticle would have a diameter, for example, of between 10 nm to about 100 nm or 10 nm to about 1000 nm.
[0063] A nanoparticle most often behaves as a unit in terms of its physical or biophysical properties, e.g., transport. It is noted that novel properties that differentiate nanoparticles from the corresponding bulk material typically develop at a size scale of under 1000 nm, or at a size of under 500 nm, but nanoparticles can be of a larger size, for example, for particles that are oblong, tubular, and the like. The size at which materials display different properties as compared to the bulk material is material-dependent and can be seen for many materials much larger in size than 100 nm and even for some materials larger in size than 1000 nm. Nanoparticles can be employed in a variety of drug delivery technologies (e.g., mRNA delivery technologies) and can be employed for various purposes including, but not limited to, controlled drug delivery, protection of the drugs from degradation, and protection of the body from the toxic effects of the drugs.
[0064] As used in this specification and the appended claims, the term “or” is generally employed in its sense including “and / or” unless the content clearly dictates otherwise.
[0065] “Parenteral” administration of an immunogenic composition includes, e.g., subcutaneous, intravenous, intramuscular, intrathecal, or intrasternal injection, or infusion techniques.
[0066] The terms “patient” or “individual” or “subject” are used interchangeably herein, and refers to a mammalian subject to be treated, with human patients being preferred. In some cases, the methods of the disclosure find use in experimental animals, in veterinary application,Docket No. 084284.00356and in the development of animal models for disease, including, but not limited to, rodents including mice, rats, hamsters, and primates.
[0067] As used herein, a “pharmaceutically acceptable” component / carrier etc. is one that is suitable for use with humans and / or animals without undue adverse side effects (such as toxicity, irritation, and allergic response) commensurate with a reasonable benefit / risk ratio.
[0068] Treatment” is an intervention performed with the intention of preventing the development or altering of the pathology or symptoms of a disorder. Accordingly, “treatment” refers to both therapeutic treatment and prophylactic or preventative measures. “Treatment” may also be specified as palliative care. Those in need of treatment include those already with the disorder as well as those in which the disorder is to be prevented. As defined herein, a “therapeutically effective” amount of a compound or agent (i.e., an effective dosage) means an amount sufficient to produce a therapeutically (e.g., clinically) desirable result.

[0069] Ranges: throughout this disclosure, various aspects of the disclosure can be presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the disclosure. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. ForDocket No. 084284.00356example, a description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual numbers within that range, for example, 1, 2, 2.7, 3, 4, 5, 5.3, and 6. This applies regardless of the breadth of the range.
[0070] Delivery of messenger RNA (mRNA) to the central nervous system (CNS) remains a significant challenge. The present document provides a library of furan-derived ionizable lipid nanoparticles that leverage the meningeal lymphatic vessel (MLVs) route to achieve efficient mRNA delivery to the brain. These ionizable lipids are engineered with different ring structures, e.g., furan or tetrahydrofuran cores, functional groups, and tails. These furan and tetrahydrofuran-containing lipid nanoparticles (LNPs) generally displayed exceptional mRNA delivery. These LNPs demonstrated significantly higher mRNA delivery efficiency to the brain compared to FDA-approved SM102 LNPs. Confocal imaging revealed that these LNPs bypassed the blood-brain barrier (BBB) via the lymphatic pathway, traveling from the deep cervical lymph nodes (dCLNs) to the meninges and subsequently entering brain cells.
[0071] In contrast to liposomes and cationic liposomes, lipid nanoparticles have a structure that includes a single monolayer or bilayer of lipids that encapsulates a compound in a solid phase. Thus, unlike liposomes, lipid nanoparticles do not have an aqueous phase or other liquid phase in their interior, but rather the lipids from the bilayer or monolayer shell are directly complexed to the internal compound thereby encapsulating it in a solid core. Lipid nanoparticles are typically spherical vesicles having a relatively uniform dispersion of shape and size ranging from about 10 nm to 1000 nm.
[0072] In the disclosed lipid nanoparticle mRNA delivery systems, the lipid is formulated to include a furan-derived ionizable lipid which can complex to and associate with the negativelyDocket No. 084284.00356charged backbone of the mRNA. Furan-derived ionizable lipids with apparent pKa values below 7 have the benefit of providing a cationic environment for complexing with the negative charge on the mRNA acid and loading into the lipid nanoparticle at pH values below the pKa of the furanderived ionizable lipid where it is positively charged. Then, at physiological pH values, e.g., pH between about 7.35 to about 7.45, the lipid nanoparticle can adopt a relatively neutral exterior allowing for a significant increase in the lifetime of the lipid particles following administration. In the context of mRNA delivery, lipid nanoparticles offer many advantages over other lipid-based nucleic acid delivery systems including greater encapsulation efficiency, potent transfection, improved delivery efficiency, and low levels of cytotoxicity and immunogenicity.
[0073] In the context of the present disclosure, a lipid nanoparticle (LNP) delivery vehicle typically serves to transport a desired therapeutic agent to a target cell or tissue. In certain embodiments, the lipid formulation encapsulates the therapeutic agent.Ionizable Lipid

[0141] In another aspect, the present disclosure also features a lipid nanoparticle composition comprising a lipid component comprising a compound according to Formula (I), (IA), (IB), (IC), (ID), (IE), (IF), (IG), (IH) or (li) as described herein.
[0142] As used herein, a “lipid component” is that component of a nanoparticle composition that includes one or more lipids. For example, the lipid component may comprise an ionizable lipid comprising a compound according to Formula (I), (IA), (IB), (IC), (ID), (IE), (IF), (IG), (IH) or (li) and a helper lipid component including but not limited to one or more PEGylated-lipid, structural-lipid, or phospholipids.
[0143] In some embodiments, the lipid nanoparticle formulation may comprise a furanderived ionizable lipid and at least one helper lipid. As used herein, the term “Helper lipid” refers to a lipid component of a lipid nanoparticle formulation that is distinct from the cationic or ionizable lipid and that functions to stabilize the lipid nanoparticle structure and / or facilitate intracellular delivery of an associated therapeutic agent, including by modulating membrane properties, promoting lipid phase transitions, or enhancing endosomal escape, without being primarily responsible for electrostatic complexation of the therapeutic agent. In some embodiments, helper lipid is a neutral or zwitterionic lipid incorporated into a lipid nanoparticle to support particle assembly, structural integrity, and biological performance, including by influencing lipid packing, curvature, fluidity, or membrane fusion behavior. In certain embodiments, the helper lipid contributes to destabilization of the endosomal membrane following cellular uptake, thereby enhancing release of the therapeutic agent into the cytosol.

The phospholipid may comprise one or more multiple (e.g. double or triple bond) bonds (e.g. one or more unsaturated bonds). Certain phospholipids may promote fusion with the membrane. For example, a cationic phospholipid may interact with one or more negatively charged phospholipids of a membrane (e.g., a cell membrane or an intracellular membrane). The fusion of the phospholipid to the membrane may allow one or more elements of the lipid-containing composition to pass through the membrane, thereby allowing, for example, the delivery of one or more elements to the cell.

[0166] Furan is a five-membered aromatic heterocycle with four carbon atoms and one oxygen atom, commonly used as a precursor in the synthesis of various pharmaceutical compounds. Tetrahydrofuran (THF) is the fully saturated version of furan, widely employed in pharmaceutical formulations for solubilizing drugs. Mono-, di-, and tri-furan cores were conjugated with various lipid chains. Similar reactions were conducted for mono- and ditetrahydrofuran-derived ionizable lipids. A representative synthetic route to tetrahydrofuranderived ionizable lipids is outlined in the following reaction mechanism.Docket No. 084284.00356OTMSB'''' i l.

[0167] A reaction between trans-1,4-dibromobutene A and allyl magnesium bromide B was initiated to yield a triene, which underwent Sharpless asymmetric dihydroxylation to give diol C. Upon treatment with N-iodosuccinimide (NIS), cyclization of diol C gave compound E.Subsequently, compound E was subjected to azidation to get F, followed by reduction with LiAlH4, leading to the formation of diamine G. The hydrophobic tails were then installed to the core amine via epoxide ring-opening reactions or reductive amination reactions, affording the corresponding furan-derived ionizable lipids. 1H nuclear magnetic resonance (1H NMR) spectra confirmed the chemical structures of the lipids.
[0168] Synthesis of compound C. A solution of trans-1,4-dibromobutene A (6.68 g, 31.25 mmol, 1.0 equiv) in Et2O (15 mL) was added dropwise to a solution of allyl magnesium bromide B (1.0 M in Et2O, 100 mL, 100 mmol, 3.2 equiv) at 0°C. The resulting mixture was stirred overnight, allowing the temperature to increase to room temperature (25°C). The reaction was then quenched by the addition of aqueous acetic acid (AcOH) (10.5 M, 3.46 mL, 36.33 mmol, 2.18 g AcOH, 2.08 mL) at 0°C. The mixture was poured onto ice (ca. 156 g). The two layers were separated, and the aqueous one was extracted with diethyl ether (Et2O) (3 x 50 mL). The combinedDocket No. 084284.00356organic layers were washed with aqueous NaHCO3 (10% w / w, 2 x 50 mL) and brine, dried over MgSO4, fdtered and the solvent was removed in vacuo.
[0169] The crude product was purified by filtration through a short silica plug (elution with pentane) to afford the triene product (2.7 g, 88.6%) as a colorless oil. Following a reported procedure, triene product (1.0 eq., 19.8 mmol, 2.70 g) was added to a suspension of AD-mix (15.4 g) and methanesulfonamide (1.05 g, 11.1 mmol, 1.01 eq.) in a solution of tert-butanol and water (100 mL / 100 mL). The resulting mixture was stirred at 0°C for 7 h and then the reaction was quenched by the addition of Na2SO3 (ca. 15 g) and allowed to warm to room temperature. The aqueous layer was extracted with ethyl acetate (EtOAc) and the combined organic layers were washed with brine, dried over MgSO4, filtered and the solvent was removed in vacuo, after purification by column chromatography diol C was obtained as colorless oil (1.0 g, 29.7%).
[0170] Synthesis of compound E. Under a nitrogen atmosphere, compound C was added to a solution of D in dichloromethane (DCM) at -78 °C. The reaction mixture was stirred for 10 min at -78 °C and N-Iodosuccinimide (NIS) was added to the mixture at -78 °C and stirred for 2 h. After being stirred for 12 h at room temperature, the reaction was quenched with sat. Na2S2O3 aqueous solution. And the mixture was extracted with DCM. The organic layer was dried over Na2SO4 and evaporated in vacuo. The residue was purified by silica gel column chromatography to give compound E as a colorless oil. 1H NMR (400 MHz, Chloroform-d) δ4.13 - 4.00 (m, 2H), 3.97 - 3.84 (m, 2H), 3.33 - 3.25 (m, 2H), 3.23 - 3.11 (m, 2H), 2.14 - 2.01 (m, 2H), 1.96 - 1.85 (m, 2H), 1.85 - 1.68 (m, 4H).
[0171] Synthesis of azide F. Sodium azide (993 mg, 15.28 mmol) was added to a solution of E (1.61 g, 3.82 mmol) inDMF (35 mL). After being stirred for 4 h at 70 °C, the reaction mixture was quenched with water. The mixture was extracted with Et2O, and then the combined organicDocket No. 084284.00356was washed with water.

[0172] Synthesis of diamine G. A suspension of LiAlH4 (8.19 mmol, 311 mg) in 25 mL of dry tetrahydrofuran (THF) was stirred while a solution of azide compound F (0.69 g, 2.73 mmol) in dry THF was added dropwise at 0 °C over a period of 10 min. The reaction mixture was warmed to room temperature and stirred for 3 h then quenched by the sequential addition of water (0.4 mL), a 15 % solution of NaOH (0.4 mL), and water (1.2 mL), the mixture was stirred for 1 h. The white precipitate was filtered off and washed with ether or THF (20 mL).

The synthetic procedure of F6T1 is similar to Fl 1T6.EXAMPLE 4: Preparation and characterization of LNPs.
[0175] LNPs were prepared using an established four-component formulation and were used to encapsulate mRNA agents: Synthesized furan-derived ionizable lipid, DOPE, cholesterol, and DMG-PEG2k. The lipid nanoparticles were formulated with DOPE, cholesterol, and DMG-PEG2k at a molar ratio of lipid / DOPE / cholesterol / DMG-PEG2k = 20 / 30 / 40 / 0.75. The initial mass ratio of furan-derived ionizable lipids to mRNA was 10:1. A control SMI 02 lipid was formulated with DSPC, cholesterol, and DMG-PEG2k at a molar ratio of SM102 / DSPC / cholesterol / DMG-PEG2k = 50 / 10 / 38.5 / 1.5, with an SM102 lipid-to-mRNA mass ratio of 11.03:1. Hydrodynamic diameter and poly dispersity index (PDI) of LNPs were measured using a NanoZS Zetasizer (Malvern), which also facilitated zeta potential measurements. LNP morphology was visualized by Cryo-TEM (Thermo Scientific Glacios), as previously described. mRNA encapsulation efficiency was measured by a modified Quant-iT RiboGreen RNA assay (Invitrogen). For in vivoDocket No. 084284.00356batch experiments and subsequent administration, furan-derived ionizable lipids were individually formulated with DOPE, cholesterol, and DMG-PEG2k at a molar ratio of lipid / DOPE / cholesterol / DMG-PEG2k = 20 / 30 / 40 / 0.75 and the mass ratio of furan-derived ionizable lipids to mRNA was 10:1.
[0176] The hydrodynamic diameter of all lipid nanoparticles comprising different furanderived ionizable lipids was measured using Zetasizer NanoZS (Malvern, UK) and determined to be 170 nm and ranged from 50 nm to 1,000 nm. The average poly dispersity index of all was measured using Zetasizer NanoZS (Malvern, UK) and determined to be 0.13 and ranged from 0.01 to 0.8. The average Zeta potential of the lipid nanoparticles was measured using Zetasizer NanoZS (Malvern, UK) and determined to be -0.25 mV and ranged from -12 mV to 5 mV. The average encapsulation efficiency of the lipid nanoparticles was measured using Quant-iT™ RiboGreen RNA Assay and determined to be 92 % and ranged from 45% to 95%.EXAMPLE 5: Batch-based experiments for in vivo evaluation.
[0177] The performance of furan-derived ionizable lipids for mRNA delivery into the brain through meningeal lymphatic vessels (MLVs), a special circulatory network between deep cervical lymph nodes (dCLNs) and the brain was evaluated. To assess the delivery efficacy of this lymphatic route to the brain, LNPs were administered subcutaneously near the dCLNs in the mouse neck. A batch-based approach was used to reduce the number of animals, time, and cost. Briefly, the LNPs were formulated to encapsulate mRNA encoding firefly luciferase (FLuc) and categorized into 11 groups based on head group structures. In each batch, prior to the subcutaneous injection, 6 LNPs with the same head group but different tails were mixed.
[0178] The mRNA delivery efficiency was appraised in vivo. The mixed LNPs were subcutaneously administered into the neck of mice, followed by In Vivo Imaging System (IVIS)Docket No. 084284.00356after 6 hours. The luminescent intensity as seen in FTG. 1 shows LNPs containing F2 group LNPs containing hydroxyl-modified mono-furan lipids exhibited superior mRNA delivery efficiency compared to Fl batch LNPs with methyl ester modifications. Nevertheless, LNPs formulated with di-furan-derived ionizable lipids did not outperform their mono-furan counterparts. Similarly, LNPs formulated with tri-furan-derived ionizable lipids did not improve the mRNA delivery performance. Interestingly, tetrahydrofuran lipids with four-tail conjugation in the F10 group demonstrated markedly higher mRNA delivery efficacy compared to their furan analogs. Additionally, replacing the hydroxyl group on tetrahydrofuran lipids with two additional lipid tails significantly enhanced mRNA delivery efficiency, as shown in LNP batches F9 and F10. Even though increasing the number of tetrahydrofuran cores to di-tetrahydrofuran resulted in a decrease in mRNA delivery efficacy, lipids in the Fl 1 group still maintained performance within the top three among various furan and tetrahydrofuran-based lipid formulations, superior to di-furan derived lipids. Therefore, the top three head groups, F2, F10, and Fl 1 were identified for further study. Particularly, F10 group LNPs displayed the most exceptional delivery efficiency.
[0179] Next, the effects of lipid tail structures on mRNA delivery were also assessed. Diverse functional groups were incorporated in the tail chains, such as ester, carbonate, and acetal. Following a similar approach to the head structure assessment, all LNPs were classified into 6 batches based on their tail structures, each batch comprising 11 LNPs. A mixture of 11 LNPs was injected into mice as described above, and then mRNA delivery efficiency was determined. As shown in FIG. 2, LNPs comprising tails with ester and acetal ether linkage were the most effective in mRNA delivery, which was over 3.3-fold higher than other LNPs as measured by luminescence intensity. Hence, two top-performing tails, T3 and T6, were identified for further characterization.Docket No. 084284.00356These orthogonal batch-based tests provided a quick method to select the head groups and lipid tails for further study.
[0180] Based on the above data, exemplary LNPs containing ionizable lipids with high-performing head groups (F2, F10, and Fl 1) and tails (T3, T6) were selected for further evaluation. SM102 LNPs, an FDA-approved LNP, was included as a control. In light of the remarkable delivery performance of the F 10 head group, furan-derived ionizable lipids containing F10 and each different tail group (T1-T6) were also tested in mice. As seen in luminescence intensity data in FIG. 3, results show that F6T1 and Fl 1T6 LNPs performed higher mRNA delivery efficiency to the brain than other LNPs. As outlined in Table 1, according to the predicted LogD (as determined through MarvinSketch), the LogD value of F2T6 lipid was 5.43, whereas the LogD values of other lipids were from 9.08 to 18.21, showing 6.9 to 42.85-fold higher luminescence intensity than F2T6 LNP in the brain. In particular, both F6T1 and Fl 1T6 lipids were near 11.0, whose luminescence intensities were up to ~40-fold higher (F6T1) than that of F2T6 lipid, indicating the LogD may be an important factor for LNP delivery to the brain via MLVs.Table 1. Predicted LogD values of different lipids.Lipid F2T3 F2T6 F5T3 F5T4 F5T5 F5T6 F6T1 F6T2 F6T5 F7T1 LogD 9.08 5.43 15.15 12.55 17.73 11.83 11.33 10.41 18.21 10.89 Luminescence6 90 12 23 19 27 16 68 16 50 42 85n36 19 n3961intensity*The luminescence intensity of F2T6 LNP for in vivo brain delivery of FLuc mRNA was defined as 1
[0181] As seen in FIG. 4, even though F6T1 LNPs showed similar luminescence intensity with Fl 1T6 LNPs in the brain, their distribution in other major organs such as the liver, spleen, and lung are lower than F7T1 LNPs. Subsequently, F6T1 and F7T1 LNPs were selected for additional delivery studies.EXAMPLE 6: Cellular trafficking of LNPsDocket No. 084284.00356
[0182] To study the cellular trafficking of these new LNPs, a series of experiments in Neuro-2a (N2a) cells, a mouse neuroblast cell line was performed. Mostly consistent with the results in mice, LNPs formulated with lipids containing F2, F10, and Fll head groups showed high mRNA delivery efficiency. Specifically, F6T1 and Fl 1T6 LNPs exhibited superior mRNA delivery to SMI 02 LNP. It was identified that F2T3 LNPs displayed high mRNA delivery efficiency at the cellular level but low efficiency for in vivo mRNA delivery, indicating the differences between in vitro and in vivo experiments. Afterwards, the cellular uptake of LNPs in N2a cells were evaluated. These LNPs were formulated with ionizable lipids containing different head groups (Fl-Fl 1) and Alexa-Fluor 647-labeled mRNA while maintaining the same tail structure (T6).
[0183] As shown in FIGS. 5A and 5B, F1T6 and F1T5 LNPs demonstrated the highest cellular uptake efficiency. Additionally, LNPs formulated with F2T6, F5T2, F2T5 and F5T1 also exhibited outstanding cellular internalization. Notably, these high-performing lipids all featured a two-tail structure, suggesting these two-tail structures were beneficial to cellular uptake. However, despite F7T1 and F6T2 LNPs achieving relatively low cellular uptake, they exhibited high expression of FLuc mRNA, implying that factors beyond internalization, such as enhanced endosomal escape capability likely accounted for the high mRNA delivery efficiency of F6T2 and Fl 1T6 LNP. the enhanced endosomal escape capability likely accounted for the high mRNA delivery efficiency of F6T2 and Fl 1T6 LNPs, despite their lower cellular uptake.
[0184] Additionally, cells incubated with Calcein alone exhibited punctuated fluorescence, indicating the endosomal sequestration of the internalized dye. In contrast, diffused green fluorescence was observed throughout the cytoplasm in cells treated withF6T2 and Fl 1T6 LNPs. The wide distribution of diffuse green fluorescence was not detected in cells treated with the otherDocket No. 084284.00356LNPs. The widespread fluorescence suggested LNP-mediated endosomal membrane escape, enabling the cytoplasmic release of mRNA. Additionally, Pearson’s correlation analysis revealed reduced colocalization of green fluorescence with the red signal of LNPs in cells treated with F6T2 and F7T1 LNPs, reconfirming the endosomal escape. Thus, the enhanced endosomal escape capability likely accounted for the high mRNA delivery efficiency of the F6T2 and Fl 1T6 LNPs.
[0185] Based on the delivery data, the mechanism of LNPs bypassing BBB via MLVs route in vivo was explored. The lymphatic delivery of Alexa-Fluor 647-labeled mRNA-loaded LNPs to the MLVs was investigated following their subcutaneous injection into the dCLNs at the mouse neck. The results indicated colocalization of LNPs and MLVs. This colocalization suggested a lymphatic pathway for LNP transport from the dCLNs to the meninges, potentially explaining their ability to bypass the BBB. Moreover, the GFP mRNA was also transported by the lymphatic delivery pathway. The GFP expression in the meninges and MLVs were monitored showing that LNPs could not only reach the meninges via lymphatic routes but, also deliver mRNA to brain cells via the MLVs.
[0186] To further examine mRNA delivery in different brain cell types, F6T1 and Fl 1T6 LNPs were loaded with GFP mRNA, and GFP expression was quantified by flow cytometry. As shown in FIG. 6A, F6T1 and F7T1 LNPs preferentially delivered mRNA to neurons. Particularly, Fl 1T6 LNP demonstrated superior neuron delivery efficiency (16.4% GFP+) and the neuron delivery efficiency of F6T1 LNP was 8.8% GFP+. Moreover, GFP mRNA was also delivered to microglia and astrocytes by F6T1 and F7T1 LNPs. In contrast, SM102 LNPs showed minimal GFP mRNA delivery efficiency to brain cells, not only in neurons (1.28% GFP+) but also in microglia (1.16% GFP+) and astrocytes (1.79% GFP+). Furthermore, as seen in FIG.Docket No. 084284.003566B, a small fraction of brain capillary endothelial cells (BCECs) also exhibited GFP expression when treated with F6T1, Fl 1T6, and SM102 LNPs.
[0187] To evaluate the potential toxicity of furan-derived LNPs, blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels were measured in mice treated with various LNP formulations. As seen in FIGS. 7A-7C, all these markers remained within normal ranges, indicating no adverse effects on hepatic or renal function following administration of F6T1 and Fl 1T6 LNPs at the tested dose.
[0188] The potential of LNPs for functional mRNA delivery in an Ail4 mouse model was also assessed. The Ail4 mouse line is genetically engineered with a LoxP-flanked stop cassette to suppress tdTomato expression at baseline but enables its induction upon exposure to Cre recombinase. In this experiment, Cre recombinase mRNA-loaded F6T1 and F7T1 LNPs were subcutaneously administered to the neck of Ail4 mice. In mice treated with PBS, tdTomato expression was negligible 7 days post-administration. As seen in FIGS. 8A-8C, following the delivery of Cre mRNA using F6T1 and Fl 1T6 LNPs, tdTomato signals were detected throughout most regions of the brain, including neurons, microglia, and astrocytes. In contrast, administration of SM102 LNPs resulted in a low tdTomato signal. Specifically, the tdTomato expression in brain cells was quantified at 8.93% and 13.0% in neurons, 7.0% and 12.1% in microglia, and 9.9% and 6.5% in astrocytes for F6T1 and Fl 1T6 LNPs. Notably, the tdTomato signals induced by F6T1 and Fl 1T6 LNPs were significantly higher than those elicited by SM102 LNPs. Collectively, these results highlighted the potential of F6T1 and Fl 1T6 LNPs as promising carriers to deliver various mRNA to important brain cell types via MLVs routes, especially neurons, which facilitated the expression of functional proteins in brain cells.Docket No. 084284.00356
