Description

[Technical field]

[0001] The present disclosure provides compounds and nanostructures that include one or more quaternary ammonium salts, compositions that include the compounds and nanostructures, and methods useful for treating conditions using the compounds, nanostructures and compositions. [Background technology]

[0002] Prevention of disease transmission on aircraft has traditionally focused on improving air conditioning / filtration systems. Recent studies have suggested that one way to further improve disease prevention on aircraft and spacecraft may include surface contamination treatment, for example, of aircraft surfaces. However, while some antimicrobial compounds have been produced for antibacterial applications, no compounds have been specifically demonstrated for antiviral applications. For antiviral compounds, the biotechnology and pharmaceutical industries use proteins and small molecules (e.g., molecular weight less than 1,000) that target microorganisms. However, proteins and small molecules have limited systemic half-lives, and as a result, they usually require higher than desirable dosages.

[0003] Furthermore, the hydrophobic bonds of existing antimicrobial materials require long dehydration times before they become effective, during which significant microbial transmission occurs, and therefore the antimicrobial activity is not effective against hardy microorganisms (such as Escherichia coli (E. Coli)).

[0004] Thus, there is a need for antimicrobial compounds and nanostructures that enable further functionalization and stronger antimicrobial activity against microorganisms (such as E. Coli), compositions comprising the compounds and nanostructures, and methods using the compounds, nanostructures and compositions useful for antimicrobial and / or antiviral applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] For ease of understanding, the same reference numbers have been used, where possible, to designate identical elements common to the figures. The figures are not drawn to scale and may be simplified for clarity. It is contemplated that elements and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

[0013] The present disclosure provides compounds and nanostructures that include one or more quaternary ammonium salts, compositions that include the compounds and nanostructures, and methods useful for treating conditions using the compounds, nanostructures and compositions.

[0014] compound In at least one embodiment, the compound has formula (I): [ka] or a pharma- ceutically acceptable salt thereof, wherein Q is fluoro, chloro, bromo or iodo, preferably chloro; each of s, b, and n is independently an integer of about 10 to about 100; Each of v, j, p, z, q, x and m is independently an integer of 1 to about 20.

[0015] In at least one embodiment, s can be an integer from about 20 to about 40, such as from about 25 to about 35. b can be an integer from about 30 to about 60, such as from about 40 to about 50. n can be an integer from about 30 to about 60, such as from about 50 to about 60. m can be an integer from about 1 to about 10, such as from about 5 to about 10. x can be an integer from about 5 to about 15, for example, 7, 11, or 15.

[0016] Without being limited by theory, an x ​​value of about 5 to about 15 provides cell membrane penetration of the alkyl moiety into the hydrophobic portion of the cell membrane (such as a viral cell), while the cationic nitrogen moiety of the compound of formula (I) provides Coulombic interaction of the compound of formula (I) (such as a quaternary ammonium moiety) with the cell membrane surface (such as the phosphate ester portion of a phospholipid bilayer). Additionally, the quaternary ammonium salt provides sufficient hydrophilicity such that the alkyl moiety attached to the quaternary ammonium salt is not significantly buried within the core of the three-dimensional structure (e.g., when the composition has a nanoworm or nanorod three-dimensional structure).

[0017] The polystyrene block of the compound of formula (I) can provide the compound of formula (I) with a high glass transition temperature (Tg) component (100% polystyrene has a Tg of about 100°C). The high Tg provides stability to the nanostructures at body temperature. Furthermore, the poly(N-isopropylacrylamide) (polyNIPAM) block can provide the compound of formula (I) with a nanoworm (or nanorod) three-dimensional shape under aqueous conditions, for example, in an aqueous solution containing sodium dodecyl sulfate (SDS).

[0018] The ratio of integer n to integer m can be selected to fine-tune the coulombic binding ability to the cell membrane permeability of the compound of formula (I). A larger value of integer n increases the coulombic binding, and a larger value of integer m increases the cell membrane permeability of the compound of formula (I). In at least one embodiment, the ratio of integer n to integer m is about 1:1 to about 100:1, such as about 5:1 to about 15:1, for example 54:7.

[0019] The values ​​of v, j, p, z, and q can be varied based on the number of, e.g., methylene units, of the starting materials used to generate the compound of formula (I). The value of s can be controlled by controlling the molar ratio of styrene monomer to NIPAM monomer and maleimide starting materials, as described in more detail below. Similarly, the value of b can be controlled by controlling the molar ratio of NIPAM monomer to styrene monomer and maleimide starting materials. The values ​​of n and m can be controlled by the ratio of, e.g., methyl halide to other alkyl halides (e.g., octyl halide) used to form the quaternary ammonium salt moiety.

[0020] In at least one embodiment, the compound of formula (I) has formula (II): [ka] or a pharma- ceutically acceptable salt thereof, wherein Q is fluoro, chloro, bromo or iodo, preferably chloro; each of s, b, and n is independently an integer of about 10 to about 100; Each of x and m is independently an integer of 1 to about 20.

[0030] The compositions of the present disclosure further comprise a compound of formula (IV): [ka] or a pharma- ceutical acceptable salt thereof (wherein, in formula (IV), s and b each independently represent an integer of about 10 to about 100; In formula (IV), v is an integer of about 1 to about 20; R 1 is -O- or -NH-, R 2 is -CH3, biotin, pyridyl disulfide, dopa, thiolactone, or adamantyl. Biotin can be of the structure: [ka] The pyridyl disulfide can be of the structure: [ka] Dopa can be of the following structure: [ka] Thiolactone is [ka] Adamantyl can be a γ-thiolactone of the structure [ka] The structure may be as follows:

[0031] R as pyridyl disulfide 2 are particularly advantageous since they can be further conjugated to a pharma- ceutical active moiety. Pharmaceutically active moieties include polymers, sugars, peptides, oligonucleotides, proteins, or small molecule (e.g., 2,000 g / mol or less) therapeutics, such as anti-cancer drugs. Proteins include glycoproteins, such as Vitronectin. Small molecule therapeutics include Relenza binding agents. Peptides include twin-arginine or translocation (TAT) peptide. Oligonucleotides include siRNA.

[0032] Additionally, pyridyl disulfides can undergo thiol-disulfide exchange or thiol-ene reactions, Dopa can be attached to metal surfaces, γ-thiolactones can undergo amination reactions (e.g., with amino acids), biotin can be attached to biomolecules (e.g., streptavidin), and adamantly can be brominated, fluorinated, carboxylated, or hydroxylated.

[0033] In at least one embodiment, s in formula (IV) is an integer of from about 25 to about 35. b in formula (IV) can be an integer of from about 40 to about 50. v in formula (IV) can be an integer of from 1 to about 10, for example, 2.

[0034] In at least one embodiment, the compound of formula (IV) is one or more of the following compounds of formula (V), formula (VI) or formula (VII) or a pharma- ceutically acceptable salt thereof: [ka] (wherein s is an integer of about 25 to about 35, and b is an integer of about 40 to about 50).

[0035] In at least one embodiment, the ratio of the compound represented by Formula (I), (II) or (III) to the compound represented by Formula (IV), Formula (V), Formula (VI) or Formula (VII) is from about 0.01:1 to about 1:0.01.

[0036] In at least one embodiment, the composition includes a compound represented by formula (I), (II) or (III), a compound represented by formula (V), and an additional compound represented by formula (IV). The ratio of the compound represented by formula (I), (II) or (III) to the compound represented by formula (V) to the compound represented by formula (IV) is about 0.99:0.005:0.005 to about 0.01:0.09:0.009, such as about 0.9:0.05:0.05 to about 0.1:0.08:0.01, such as about 0.8:0.1:0.1 to about 0.1:0.1:0.8.

[0037] Three-dimensional structure of a compound or composition The long, flexible worms have an in vivo blood circulation time approximately 10 times longer than their spherical analogues, and a circulation time significantly longer than any synthetic particle or polyethylene oxide-coated vesicle, whereas the short rods have a much shorter circulation time but are taken up by cells more efficiently.

[0038] The compounds or compositions of the present disclosure may have a three-dimensional structure that is a nanoworm or nanorod. The nanorod may have an aspect ratio of about 10:1 to about 1000:1, such as about 25:1 to about 75:1, such as about 10:1 to about 100:1. The nanorod may have a diameter of about 10 nm to about 20 nm and a length of about 100 nm to about 10 microns, such as about 1 micron to about 2 microns.

[0039] The compounds and compositions of the present disclosure may also have a three-dimensional structure that is a sphere, a vesicle, a donut, or a lamellar sheet. The three-dimensional structure of the compositions of the present disclosure may be stable in water for long periods (e.g., nanoworms are stable at room temperature for more than one year), and can be lyophilized and rehydrated without structural reorganization. For example, nanoworm solutions can be lyophilized to obtain dry power. The lyophilized product can be rehydrated in Milli-Q water at 8 wt% for 2 hours. The ability of the compositions of the present disclosure to be lyophilized allows the compositions of the present disclosure to be transported stably.

[0040] Nanoworm Generation Preparation of functional thermoresponsive polymer nanorods: RAFT-mediated polymerization of styrene using functional poly(NIPAM) macro-chain transfer agent (macro-CTA) in water: A precursor compound (e.g., a compound represented by formula (I) but not including a polystyrene block) can be mixed with styrene, sodium dodecyl sulfate, and azobisisobutyronitrile (AIBN) in water (such as Milli-Q water) to produce a reaction mixture. One or more additional precursor compounds (e.g., a compound represented by formula (IV) but not including a polystyrene block) can also be added to the reaction mixture.

[0041] AIBN can be dissolved in styrene and then the solution can be added to a flask containing the other reaction ingredients to produce a reaction mixture. The solution of AIBN and styrene can be deoxygenated by purging with argon for, e.g., about 15 minutes. The reaction mixture can be purged with argon in an ice bath for, e.g., about 10 minutes, and then heated to 70° C. for about 3.5 hours to produce a product mixture.

[0042] The number average molecular weight (Mn) of the compound of formula (IV) in the product mixture is determined by nuclear magnetic resonance spectroscopy unless otherwise stated. 1 H NMR can be measured by lyophilizing the product mixture to remove all water and low boiling compounds, then dissolving the product mixture in CDCl3. Size exclusion chromatography spectra can be obtained by taking 3 drops of the latex, dissolving in 1 mL of THF, filtering, and injecting the solution into the SEC instrument.

[0043] Alternatively, the conversion of the styrene monomer can be determined gravimetrically. The theoretical molecular weight can be calculated based on the monomer conversion. Molecular weight (M n(SEC) ) and PDI SEC can be obtained by THF SEC. n(NMR) )teeth 1 Obtained from H NMR. Particle size (D h ) and particle size distribution (PDI DLS ) could be measured by dynamic light scattering (DLS) at 70 °C immediately after the reaction was stopped, and the results were the average values ​​based on three measurements. PDI less than 0.1 DLS means that the distribution is narrow.

[0044] Nanoworms cut into nanorods using ultrasound Nanorods can be obtained by temperature directed morphology transformation (TDTM) and ultrasonic cutting of nanoworms. In at least one embodiment, 6 mL of latex solution of nanoworms can be transferred into two hot vials (3 mL each) with 60SL of toluene in each vial. These vials can then be sealed and shaken. The suspension in these vials can be cooled to 23°C. The latex solution can be cooled from 70°C to 15°C for about 30 minutes. To confirm the generation of worm-like nanostructures, the nanostructures can be characterized by transmission electron microscopy (TEM). To generate rods, the worms can be diluted by adding 10 mL of Milli-Q water and cut in an ice bath with an ultrasonic probe (pulsed 3 seconds on and 2 seconds off as one pulse cycle) at 35% power for 3 minutes (3 mm tapered microtip, VC-750 system from Sonics&Materials). After ultrasonic cutting, the nanostructures can be characterized again by TEM to confirm the generation of rods.

[0045] Ultrasonic cutting of nanoworms into nanorods can also be performed by applying probed ultrasound with different pulse cycles (15 s on and 10 s off as one pulse cycle), (B) 12 cycles (3 min), (C) 36 cycles (9 min) and (D) 48 cycles (12 min).

[0046] In at least one embodiment, the nanoworm or nanorod compositions of the present disclosure can be heated above the lower critical solution temperature (LCST) of the PNIPAM block (about 37° C.) to form a gel, which dissociates back into a sol when cooled, i.e., a reversible process. Nanoworms can form gels at a minimum weight fraction of about 1 wt % to about 8 wt % in aqueous solution. Nanorods can form gels at a minimum weight fraction of about 2 wt % to about 16 wt % in aqueous solution. Without being limited by theory, gels are advantageous because they dissociate at elevated temperatures (e.g., from room temperature to the body temperature of a subject, such as a human), allowing dissociation of the worm three-dimensional structure and movement through the blood.

[0047] The weight percent of nanorods in water that can produce a gel at 37° C. can be determined as follows: In general, lyophilized nanorods (e.g., 20 mg) can be redispersed in Milli-Q water by vortexing in a 1.5 ml Eppendorf tube at 25° C. at 30 wt%. The tube can then be capped and immersed in a 37° C. water bath for 2 minutes. The tube can then be inverted under the water bath and observed for gel formation. Gel formation is defined as no fluid flow being observed within 30 seconds. The weight percent can be lowered by adding more Milli-Q water and vortexing. Gel formation can then be checked again. The minimum weight percent of nanorods (e.g., in water) that will produce a gel at 37° C. is defined as the wt% that will produce a gel.

[0048] Preferred Methods for the Synthesis of Compounds of Formula (I) A preferred method for synthesizing a compound of formula (I) is shown in Scheme 1. A pyridyl disulfide-capped diblock copolymer is reacted with a maleimide-capped quaternary ammonium polymer in the presence of tris(2-carboxyethyl)phosphine (TCEP) in water to produce a compound of formula (I). The pyridyl disulfide-capped diblock copolymer can be a compound of formula (IV) or (V) as the starting material to be reacted with a maleimide-capped quaternary ammonium polymer to produce a compound of formula (I). Scheme 1 [ka]

[0049] Methods for depositing compounds and compositions The compounds and compositions of the present disclosure may be deposited on the surface of an object by any suitable deposition method.Deposition methods may include one or more of painting, dipping, spraying, marking, taping, brushing, spin coating, roll coating, doctor blade coating.Before deposition, the compounds or compositions of the present disclosure may be diluted in a solvent such as water.After deposition, the solvent may then evaporate at room temperature to form a compound / composition layer on the object.

[0050] In at least one embodiment, the object is an interior surface of an aircraft / spacecraft / boat or an air filter surface of an aircraft / spacecraft / boat, such as the surface of an air conditioning or filtration system.The object can be the interior floor surface, seat surface, overhead bin surface, ceiling surface, door surface and / or door handle surface of an aircraft.

[0051] In at least one embodiment, the compound or composition of the present disclosure is sprayed onto the surface of the object for about 1 second to about 10 minutes, such as about 30 seconds to about 2 minutes. In at least one embodiment, the compound or composition is sprayed onto the surface of the object in an amount of about 1 mL to about 25 kL, such as about 100 L to about 1 kL.

[0052] The compounds or compositions of the present disclosure disposed on an object can prevent, reduce and / or eliminate the presence of bacteria and viruses, thereby preventing, reducing and / or eliminating human contact with such bacteria and viruses.

[0053] Compositions comprising the nanostructures (e.g., nanorods or nanoworms) of the present disclosure are advantageous for deposition on a surface, for example, because antibacterial and antiviral compounds can be applied as a monolayer, maintaining the efficacy of both compounds. As described above, for example, a composition comprising a conventional antimicrobial compound can be applied to a surface to form a first layer on the surface. For example, a composition comprising a conventional antiviral compound can be applied to the first layer to form a second layer. However, the second layer (antiviral layer) will mask (hinder the antimicrobial capabilities of) the antimicrobial first layer.

[0054] Applying the nanostructured composition as a single layer also reduces the cost and time of applying the compound to a surface as compared to applying two or more layers.

[0105] All functional poly(NIPAM) macro-CTAs were synthesized by reversible addition-fragmentation chain transfer polymerization (RAFT polymerization) in DMSO at 60 °C. The feed ratio of NIPAM / RAFT agent / AIBN was kept at 44 / 1 / 0.1 for all different functional RAFT agents. The ratio of DMSO to NIPAM was kept at 2 / 1 (v / w). Typically, (10 g, 8.85 × 10 -2 mol), methyl-RAFT (0.58 g, 2.0 × 10 -3 mol) and AIBN (3.3 mg, 2.0 × 10 -4 mol) was dissolved in 20 mL of DMSO. The mixture was purged with argon for 30 min and then heated at 60° C. for 16 h. The reaction was stopped by cooling to 0° C. in an ice bath and exposed to air. The solution was then diluted with 500 mL of DCM and washed with Milli-Q water (5×100 mL). The DCM phase was then dried over anhydrous MgSO4, filtered, and concentrated by rotary evaporation. The polymer was recovered by precipitation in a large excess of diethyl ether (500 mL), isolated by filtration, and then dried under vacuum at room temperature for 24 h to give a yellow powder product (45% yield). 1 The conversion was 96% as determined by 1 H NMR spectroscopy.

Other components present in the reaction mixture were styrene (0.35 g); SDS (14.5 mg), AIBN (1.2 mg), Milli-Q water (6.25 g). Dopa-poly(NIPAM) macro-CTA 3 (0.105 g, 1.33 × 10 -5mol), biotin-poly(NIPAM) macroCTA 4 (0.07 g, 1.66 × 10 -5 mol) and SDS (7.25 mg, 5 × 10 -5 AIBN (0.6 mg, 3.7 × 10 mol) was dissolved in cold water (3.125 g) in a Schlenk tube. The mixture was deoxygenated by purging with argon for 15 min. -6 mol) to styrene (0.175 g, 1.7 × 10 -3 ) and the solution was then injected into a Schlenk flask. The mixture was then purged with argon in an ice bath for an additional 10 minutes and then heated to 70°C for 3.5 hours. The reaction was quenched by exposure to air at 70°C. The polymer emulsion was then analyzed by SEC, 1 It was characterized by H NMR and DLS, and the data are shown in Table 2.

[0110] Furthermore, transmission electron microscopy images of the 60% Dopa-functional / 40% biotin-functional composition show that the three-dimensional structure of the composition is a nanoworm. 1 H NMR showed an average of 45 repeating NIPAM units and 29-30 repeating PSTY units in each of the diblock polymers.

[0111] Coating surfaces with nanoworms The glass slips (and silicon wafers) were washed sequentially with aqueous 10% HCl, acetone and methanol. The slips were then dried under a stream of nitrogen. In four 50 ml plastic vials (a, b, c and d), 10 mg of 60% Dopa- and 40% biotin-functionalized nanoworms were added in each vial, dispersed in 4 ml of tris(hydroxymethyl)aminomethane (Tris) solution (10 mM, pH=8.5) and allowed to rehydrate for 20 min. The glass slips and silicon wafers were added. Different amounts (1, 60, 120, 240 μL) of dopamine solution (33 mg / ml) were then added to vials a, b, c and d, respectively. The mixture was then shaken for 4 h. The silicon wafers were removed, washed with water and dried for SEM imaging. The glass slips were washed with water and then immersed in 0.5 ml of SAv-DyLight 550 protein solution for 1 min. The slips were then washed again with water and stored in water for fluorescence microscopy.

[0112] Fluorescence images (a–d) of 60% Dopa- and 40% biotin-functionalized nanoworms on glass slips to which different amounts of free dopamine ((a) 0 mg / ml, (b) 0.5 mg / ml, (a) 1.0 mg / ml, and (e) 2.0 mg / ml) had been added and then treated with SAv-550 solution showed that biotin incorporation was nearly quantitative on the surface of the worms.

[0113] SEM (e–h) of silicon wafers coated with 60% Dopa- and 40% biotin-functionalized nanoworms showed that 4 h of coating and 1.0 mg / ml of free dopamine gave the best coating on both the glass slip and silicon wafer.

Polymerization was allowed to proceed at room temperature for 6.5 h, with a conversion of 41%. The polymerization mixture was then diluted with acetone and passed through neutral Al2O3 to remove copper, and the solution was concentrated, precipitated three times in petroleum spirits, and dried under high vacuum, yielding 3.5 g of polymer. M by NMR was n = 9740. Figure 1 shows the structure of the polymer in deuterated chloroform (CDCl3). 1 1 H nuclear magnetic spectrum. For the polymer shown in FIG. 1, n is an integer equal to 61.

[0115] Synthesis of the quaternized furan-protected maleimide PDMAEA Poly-DMAEA was quaternized using methyl iodide and 1-iodoalkanes of different chain lengths (as shown in Table 3) as shown in Scheme 6. Poly-DMAEA was reacted with long chain iodoalkanes at 60° C. for 8 hours. The solution was cooled to room temperature and the corresponding amount of iodomethane was added. The reaction was allowed to stir at room temperature overnight. The reaction mixture was then precipitated in acetone to give a pale yellow powder, which was then dried under high vacuum. Scheme 6 [ka]

[0116] [Table 3]

[0117] Deprotection of the quaternized furan-protected maleimide polyDMAEA As shown in Scheme 7, the quaternized polyDMAEA was then dissolved in DMSO (0.2 g in 4 ml) and then heated at 120° C. for 3 h. The residue was then precipitated in acetone to give a light brown polymeric material. The polymer was characterized by NMR to confirm the maleimide chain ends. The percentage of long carbon chains was very close to the target amount (~10%). Scheme 7 [ka] Figures 2A, 2B, and 2C show the results of the reaction of maleimide-functionalized quaternized polyDMAEA in DO. 1 H NMR spectra are shown (n=61): (Figure 2A) 10 mol% 1-iodooctane, (Figure 2B) 10 mol% 1-iodododecane, and (Figure 2C) 10 mol% 1-iodohexadecane.

[0118] Conjugation of maleimide-functional cationic polymers with Dopa- and PDS-functional nanoworms Figure 3 is a scheme showing the conjugation of maleimide-functional cationic polymers with Dopa- and PDS-functional nanoworms. Maleimide-functional cationic polymers A, B or C (12.7 mg each) were placed in an Eppendorf tube and 1 ml of water was added. After the polymers were dissolved, a solution of polymer A, B or C was added to another Eppendorf tube containing nanoworms Dopa-(60%) and PDS-(40%) (20 mg nanoworms). Then, 10 μl of TCEP solution (32.5 mg / ml) was added, the Eppendorf tube was wrapped in aluminum foil (protected from light) and the tube was shaken overnight. The final products had the chemical structures shown below, where nanoworm A had n=7, nanoworm B had n=11 and nanoworm C had n=15. [ka]

The top of the plate was covered with Parafilm, then the lid was placed on top, and then more Parafilm was used to seal the edges to prevent solvent evaporation. The plates were then placed in a 37°C incubator and shaken at 120 rpm for 14 hours.

[0121] Antibacterial testing of functional cationic nanoworms A, B and C in solution Experimental Setup · For nanoworms A, B and C, 5mg / ml solutions were prepared in water. · To a 24-well plate, 500μl of the nanoworm solution in water was added in duplicate, and 500μl of water was added to the LB blank and wells that would receive E. coli. 1x10 E. coli solution in the well containing the polymer in water 5 500 μl of cells / ml was added. 500 μl of LB was added to blank wells. The top of the plate was covered with Parafilm, then the lid was placed on top, and then more Parafilm was used to seal the edges to prevent evaporation. The plate was placed in a 37°C incubator and shaken at 120 rpm for 14 hours. · Because of the color of the solution, E. coli could not be measured using the usual method of measuring OD. Growth of E. coli was monitored by plating the nanoworm / E. coli solution on LB agar plates. Dilutions were made in LB and 20 μl were plated and left in the incubator turned on.

[0122] Figures 5A-5D are scanning electron microscopy images showing the antibacterial activity of cationic polymer nanoworms A, B, and C against E. coli. (Figure 5A) LB blank and E. coli controls, (Figure 5B) nanoworm B, (Figure 5C) nanoworm C, and (Figure 5D) nanoworm D, all at different dilutions (10 as indicated). 2 , 10 4 and 10 6 )). All nanoworms could kill almost 100% of the bacteria. Only one E. coli colony was found (circled in Figure 5D). Meanwhile, many E. coli colonies were found on the +ve control plate (Figure 5A). This indicated that the cationic polymer nanoworms could efficiently kill almost all E. coli.

[0123] Overall, it was revealed that the use of SAv-biotin binding experiments and SEM demonstrated that nanoworms can be effectively coated onto glass slips and silicon wafers. Maleimide-functionalized cationic polymers showed significant inhibition (>90%) of E. coli growth. Further conjugation of these maleimide-functionalized nanoworms onto PDS- and Dopa-functionalized nanoworms retained the antibacterial properties.
