According to some embodiments, m is an integer selected from 1 to 50, particularly from 1 to 40, more particularly from 1 to 30, more particularly from 3 to 25, most particularly from 2 to 5. These R2groups are hydrophilic and thus provide advantages in certain formulations. For example, without wishing to be bound by any particular theory, the hydrophilic nature of these R2groups improve stability of micelles, liposomes and lipid nanoparticles that are used to deliver aqueous and / or polar drugs or other therapeutic agents.

As such, it should be understood that in some embodiments the compound has a structure (I), (II), (III), (IV), (IE), (IIE), (IIIE) or (IVE), or a combination of any two or more thereof. Without wishing to be bound by theory, the spacer or extender group (E) is believed to ease problems associated with steric hindrance during manufacture of the compound having a structure (I), (II), (III), or (IV), leading to improved yields of product, but without losing the beneficial hydrophilic properties of the compound. 2103173-000267 Additionally, or alternatively, R3, as described above, may also further comprising a spacer or extender group (E), such that R3is selected from Formula (VE) or (VIE): 2103173-000267 Without wishing to be bound by theory, the spacer or extender group (E) is believed to ease problems associated with steric hindrance during manufacture of the compound having a structure (V) or (VI), leading to improved yields of product, but without losing the beneficial hydrophilic properties of the compound.

As such, preferably n is 0, 1 or 2, more preferably 1 or 2. Furthermore,preferably X is the alkyl chain -CH2-, or -CH2CH2-.Suitably, where the compound has a structure (IE), (IIE), (IIIE), or (IVE), such that the compound comprises the optional spacer or extender group (E), the R3 group of the structure also comprises the spacer or extender group (E). 2103173-000267 According to a further embodiment, the compound (i.e. further comprising the spacer or extender group (E)) has the structure: Reference to the structure (I), (II), (III), or (IV) throughout the description below also encompass the embodiments wherein said structure or a combination of any two or more thereof further comprise the spacer or extender group (E) in accordance with structures (IE), (IIE), (IIIE), or (IVE) and / or where R3further comprises the spacer or extender group (E), as described above. Liver Asialoglycoprotein Receptor-Targeted Therapeutic Agent As is known in the art, the N‑acetylgalactosamine moieties of the structures (I), (II), (III), or (IV) bond to liver asialoglycoprotein receptors and thus the liver uptakes the drug or oligonucleotide in a lipid nanoparticle, liposome or micelle which includes the compound of the structure (I), (II), (III), or (IV), or a combination of any two or more thereof via the asialoglycoprotein receptor (ASGPR) pathway. According to some embodiments, RNA or DNA may be delivered to the liver in lipid nanoparticles (LNP). The present lipid compounds having structures (I), (II), (III), or (IV) are part of the lipids in the formulation of LNP. The outer layer of LNP will contain DSPE-PEG2K-triGalNAc with triantennary GalNAc (Example 1, below) targeting groups projecting out of the LNP. LNP with GalNAc will accumulate more on hepatic cell surfaces and achieve the targeting delivery effect. According to an embodiment, a liver asialoglycoprotein receptor-targeted therapeutic agent comprising a drug or oligonucleotide conjugated with and / or covalently bound to a compound having the structure (I), (II), (III), or (IV), or a combination of any two or more thereof is provided. According to some embodiments, the compound having the structure (I), (II), (III), or (IV), or a combination of any two or more thereof may be in the form of a liposome. 2103173-000267 According to some embodiments, the compound having the structure (I), (II), (III), or (IV), or a combination of any two or more thereof may be in the form of a micelle. According to some embodiments, the present compounds having structure (I), (II), (III), or (IV) are useful when used as part of liver asialoglycoprotein receptor- targeted therapeutic agents that are in the form of lipid nanoparticles (LNP) that are designed to specifically target the liver. As in known in the art, these compounds (I), (II), (III), or (IV) may be used in conjunction with other lipids to form the LNP that encapsulates a therapeutic agent that targets the liver. Non-limiting examples of other lipids that may be used in conjunction with compounds having structure (I), (II), (III), or (IV) are ionizable cationic lipids, permanently charged cationic lipids, polyethylene glycol (PEG) lipids, and / or cholesterol. Since the liver is able to synthesize proteins, delivery of various drugs or oligonucleotides via these LNPs that include compounds having the structure (I), (II), (III), or (IV) are especially attractive, since the present compounds target the liver asialoglycoprotein receptor. Thus, these compounds can be useful to deliver gene therapy to a patient in need thereof. Suitable drugs may be antibodies, enzymes, proteins, small molecules, nucleotides, and especially drugs that are used to treat diseases of the liver. These include but are not limited to treatments for hepatitis A, B or C, medications for bile acid synthesis disorders, medications for cholestatic pruritus in alagille syndrome, medications for hepatic tumors, medications for hepatic coma, medications for hyperbilirubinemia, medications for variable causes of liver cirrhosis, medications for liver metastasis in adenocarcinoma, medications for metabolic dysfunction-associated steatotic liver disease, medications for pancreatic exocrine dysfunction, medications for portal hypertension, medications to treat glycogen storage disorders, or medications for progressive familial intrahepatic cholestasis, medications for liver cancer. Specific examples may include cholic acid, maralixibat, odevixibat, sorafenib, phenobarbital, ursodiol, colchicine, azathioprine, obeticholic acid, floxuridine, pioglitazone, orlistat, betaine, rosiglitazone, rosiglitazone, pancrelipase, propranolol, nadolol, odevixibat, doxorubicin. For example, many types of APIs (active pharmaceutical ingredient) can be included in a lipid particle, but the drug properties will dictate different composition and processing conditions. Hydrophilic drugs can be loaded into a liposome’s aqueous core. Lipophilic drugs can be loaded into the liposomal bilayer or sequestered in a micelle. Anionic drugs (oligonucleotides or proteins, for example) can be loaded into lipid nanoparticle. Both hydrophilic and hydrophobic drugs can be loaded into emulsion preparations that include the subject compounds. 2103173-000267 Different size nucleic acids coding for expression or suppression of proteins, or editing of bases, codons, etc. through variable actions may be included in therapeutic agents that utilize the subject compounds. For example, some suitable oligonucleotides are ABE (adenine base editor), miRNA inhibitors, antisense oligonucleotides, ribozymes, DNAzymes, plasmids, immune stimulating nucleic acids, antagomir, antimir, mimic, supermir, and aptamers, allele-specific oligonucleotide, antisense oligonucleotide, ribonucleoproteins (RNP), mRNA, siRNA, sgRNA, gRNA, ss-siRNA. According to some embodiments, CRISPR (clustered regularly interspaced short palindromic repeats) base editing therapy can be delivered the liver using the present N‑acetylgalactosamine moieties of the structures (I), (II), (III), or (IV). The therapeutic agents may be formulated into a composition for administration to a patient in need thereof. A formulated composition can assume a variety of states. In some examples, the composition may be at least partially crystalline, uniformly crystalline, and / or anhydrous (e.g., less than 80, 50, 30, 20, or 10% water). In another example, the formulation is in an aqueous phase, e.g., in a solution that includes water. The aqueous phase or the crystalline compositions can, e.g., be incorporated into a delivery vehicle, e.g., a lipid nanoparticle. Generally, the composition is formulated in a manner that is compatible with the intended method of administration. In some embodiments, the liver asialoglycoprotein receptor-targeted therapeutic agent comprising a drug or oligonucleotide in the form of a lipid nanoparticle, and / or in the form of a liposome including a compound having the structure (I), (II), (III), or (IV), or a combination of any two or more thereof may be prepared by at least one of the following methods: spray drying, lyophilization, vacuum drying, evaporation, fluid bed drying, or a combination of these techniques; or sonication with a lipid, freeze-drying, condensation and other self-assembly. The liver asialoglycoprotein receptor-targeted therapeutic agent comprising a drug or oligonucleotide in the form of a lipid nanoparticle including a compound having the structure (I), (II), (III), or (IV); or a combination of any two or more thereof may be formulated into pharmaceutical compositions suitable for administration. The liver asialoglycoprotein receptor-targeted therapeutic agent comprising a drug or oligonucleotide and the compound having the structure (I), (II), (III), or (IV) may also be in the form of a lipid nanoparticle or may be in the form of a liposome. As is known in the art, liposomes have one or more rings of lipid bilayer surrounding an aqueous pocket, but lipid nanoparticles usually only have a single phospholipid outer layer that encapsulates the interior, which may be non-aqueous. 2103173-000267 The therapeutic agent, e.g. drug and / or oligonucleotide preparation can be formulated for delivery in a membranous molecular assembly, e.g., a liposome or a micelle. As used herein, the term "liposome" refers to a vesicle composed of amphiphilic lipids arranged in at least one bilayer, e.g., one bilayer or a plurality of bilayers. Liposomes include unilamellar and multilamellar vesicles that have a membrane formed from a lipophilic material comprising a compound having structure (I), (II), (III), or (IV), or a combination of any two or more thereof and an aqueous interior. The interior aqueous or non-aqueous portion contains the therapeutic agent composition. The lipophilic material isolates the aqueous interior from an aqueous exterior, which typically does not include the therapeutic agent composition, although in some examples, it may. Liposomes, micelles and lipid nanoparticles are useful for the transfer and delivery of active ingredients to the site of action. Because the liposomal or lipid nanoparticle or micelle membrane is structurally similar to biological membranes, when liposomes, lipid nanoparticles or micelles are applied to a tissue, the exterior layer of the lipid particle fuses with bilayer of the cellular membranes. As the merging of the liposome, lipid nanoparticle, or micelle and cell progresses, the internal contents that include the therapeutic agent composition are delivered into the cell. As discussed herein, the compound having structure (I), (II), (III), or (IV) target the liver asialoglycoprotein receptor. "Micelles" are defined herein as a particular type of molecular assembly in which amphipathic molecules are arranged in a spherical structure such that all the hydrophobic portions of the molecules are directed inward, leaving the hydrophilic portions in contact with the surrounding aqueous phase. The converse arrangement exists if the environment is hydrophobic in which inverted micelles are formed. A micelle containing a drug can be prepared by a variety of methods. In one example, the lipid component is dissolved in a detergent, emulsifier, and / or surfactant so that micelles are formed with the lipid component. For example, the lipid component can include the present compound having structure (I), (II), (III), or (IV) or combination of any two or more thereof. The detergent can have a high critical micelle concentration and may be nonionic. Exemplary detergents, emulsifier, and / or surfactants include cholate, CHAPS (3-((3-cholamidopropyl) dimethylammonio)-1-propanesulfonate), octylglucoside, deoxycholate, and lauroyl sarcosine. The drug preparation is then added to the micelles that include the lipid component, to yield a micelle preparation of a drug. A mixed micellar formulation suitable for delivery through transdermal membranes may be prepared by mixing an aqueous solution of the oligonucleotide or drug composition, an alkali metal C8 to C22 alkyl sulphate, and micelle forming compounds. Exemplary micelle forming compounds include lecithin, hyaluronic acid, 2103173-000267 pharmaceutically acceptable salts of hyaluronic acid, glycolic acid, lactic acid, chamomile extract, cucumber extract, oleic acid, linoleic acid, linolenic acid, monoolein, monooleates, monolaurates, borage oil, evening of primrose oil, menthol, trihydroxy oxo cholanyl glycine and pharmaceutically acceptable salts thereof, glycerin, polyglycerin, lysine, polylysine, triolein, polyoxyethylene ethers and analogues thereof, polidocanol alkyl ethers and analogues thereof, chenodeoxycholate, deoxycholate, and mixtures thereof. The micelle forming compounds may be added at the same time or after addition of the alkali metal alkyl sulphate. Mixed micelles will form with substantially any kind of mixing of the ingredients, but vigorous mixing will provide smaller size micelles. In one method a first micellar composition is prepared which contains the oligonucleotide or drug composition and at least the alkali metal alkyl sulphate. The first micellar composition is then mixed with at least three micelle forming compounds to form a mixed micellar composition. In another method, the micellar composition is prepared by mixing the oligonucleotide or drug composition, the alkali metal alkyl sulphate and at least one of the micelles forming compounds, followed by addition of the remaining micelle forming compounds, with vigorous mixing. Phenol and / or m-cresol may be added to the mixed micellar composition to stabilize the formulation and protect against bacterial growth. Alternatively, phenol and / or m-cresol may be added with the micelle forming ingredients. An isotonic agent such as glycerin may also be added after formation of the mixed micellar composition. For delivery of the micellar formulation as a spray, the formulation can be put into an aerosol dispenser and the dispenser is charged with a propellant. The propellant, which is under pressure, is in liquid form in the dispenser. The ratios of the ingredients are adjusted so that the aqueous and propellant phases become one, i.e., there is one phase. If there are two phases, it is necessary to shake the dispenser prior to dispensing a portion of the contents, e.g., through a metered valve. The dispensed dose of pharmaceutical agent is propelled from the metered valve in a fine spray. Propellants may include hydrogen-containing chlorofluorocarbons, hydrogen containing fluorocarbons, dimethyl ether and diethyl ether. In certain embodiments, HFA 134a (1, 1, 1,2 tetrafluoroethane) may be used. The specific concentrations of the essential ingredients can be determined by relatively straightforward experimentation. For absorption through the oral cavities, it is often desirable to increase, e.g., at least double or triple, the dosage for through injection or administration through the gastrointestinal tract. 2103173-000267 Commonly used techniques for preparing lipid aggregates of appropriate size for use as delivery vehicles include sonication and freeze-thaw plus extrusion (see, e.g., Mayer, et al. Biochim. Bio phys. Acta 858: 161, 1986). Microfluidization, high pressure extrusion, high pressure homogenization or solvent injection can be used when consistently small (50 to 200 nm) and relatively uniform aggregates are desired. Lipid nanoparticle (LNP) is a vesicle formed of multiple lipid components and an oligonucleotide, where a complex interaction forms between the oligonucleotide and one or more of the lipidic components to create particle, which may have a solid core. Lipid nanoparticles may include four types of lipids. These are neutral phospholipids (helper lipids), cationic lipids, sterol, and polymeric lipids. The present compounds (I), (II), (III), or (IV) may be used either as phospholipids or polymeric lipids. The purpose of the compounds having structure (I), (II), (III), or (IV) is thus to improve the stability of the nanoparticle. Lipid nanoparticles may be prepared by mixing solvent / lipid mixture including the present compounds (I), (II), (III), or (IV) with an aqueous buffer solution containing protein(s), small molecules(s), enzyme(s) oligonucleotide(s) and / or drug(s). A 1:3 ratio of lipid mixture to aqueous buffer is generally used. The general method is to combine the lipid elements with the therapeutic agent (oligonucleotides, proteins, enzymes, or drugs) under controlled conditions to precipitate lipid nanoparticles. Non- limiting examples of suitable solvents are those that are miscible with water, including C1-C4 alcohols, methanol, ethanol, propanols, butanols, for example. Suitable aqueous buffers are those that maintain a pH in the correct buffering range for the lipids and cargo present. Such compositions include the liver asialoglycoprotein receptor-targeted therapeutic agent comprising a drug or oligonucleotide in the form of a lipid nanoparticle including a compound having the structure (I), (II), (III), or (IV), or as a liposome, or as a micelle and a pharmaceutically acceptable carrier. As used herein the language “pharmaceutically acceptable carrier” is intended to include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. The use of such media and agents for pharmaceutically active substances is well known in the art.
