Abstract
Description
[Technical Field]
[0001] The present invention relates to a benzotriazole vinyl monomer capable of absorbing high-energy violet light (HEVL) radiation (having wavelengths of 380 nm to 450 nm), and to its use in manufacturing hydrogel contact lenses capable of blocking ultraviolet ("UV") radiation and HEVL radiation. [Background technology]
[0002] LED lighting and electronic devices, such as smartphones, computer screens, LCDs, and LED televisions, are widely used. These typically emit short-wavelength visible light, including violet light (380–450 nm) and blue light (450–495 nm). Such short-wavelength visible light has been shown to damage cells in both in vitro and in vivo studies reported in Experimental Eye Research 2006,83,1493; J. Cataract Refrac Surg 2009,35,354; Graefe's Arch Clin Exp Ophthalmol 2008,246,671; Acta Ophthalmologica Scandinavica 2006,84,4; Br J Ophthalmol 2006,90,784; and Optometry and Vision Science 2011,88(6),1.With the widespread use of LED lighting and LED displays, such as smartphones, televisions, and computer monitors, significant efforts are being made to develop HEVL-filtering ophthalmic lenses, such as eyeglasses, contact lenses, and intraocular lenses, to protect the eyes from increasing HEVL exposure (for example, U.S. Patent Nos. 4612358, 4528311, 4716234, 4878748, 5400175, 5662707, 6158862, 6955430, 7556376, 7803359, 8153703, 8232326, etc.). Specifications No. 8360574, No. 8585938, No. 8882267, No. 9377569, No. 9683102, No. 9814658, No. 10551637, and No. 10610472, U.S. Patent Application Publication No. 20170242274, and No. 20180371139 See the following specifications: (See the document, and specifications No. 20190002415, No. 20190002459, No. 20190271798, No. 20190339544, No. 20200002267, No. 20200095187, No. 20200407324, and No. 20200407337).
[0003] TOTAL30® (manufactured by Alcon) is the first contact lens that maintains effective HEVL filtering performance while the lens is being worn, regardless of lighting conditions. TOTAL30® not only includes Class I UV absorption for protection against UVA and UVB rays (i.e., filtering over 90% of UVA and 99% of UVB rays), but can also filter approximately 33% of HEVL rays (380-450nm) that enter the eye. Alcon subsequently launched a second product, TOTAL1®, which, like TOTAL30®, can block 90% of UVA, 99% of UVB, and 33% of HEVL. Johnson & Johnson Vision Care recently launched ACUVUE® OASYS MAX 1-DAY, which, according to its published 510(k) Premarket Notification (K210930), can block up to 45% of HEVL.
[0004] However, to better protect the wearer's eyes from HEVL damage, particularly violet light damage, contact lens products with significantly higher HEVL filtering performance than currently available commercially are desirable. However, finding a suitable polymerizable HEVL-absorbing dye that can absorb a considerable amount of HEVL light, has good solubility in the lens-forming composition, good compatibility with other polymerizable components in the lens-forming composition, and good lightfastness is extremely difficult. [Overview of the project] [Problems that the invention aims to solve]
[0005] Therefore, there is still a need for novel HEVL-absorbing vinyl monomers suitable for the manufacture of hydrogel contact lenses that can significantly filter HEVL, particularly silicone hydrogel contact lenses, and for such high HEVL-filtering hydrogel contact lenses. [Means for solving the problem]

Furthermore, by having an absorption peak at wavelengths of 410nm to 425nm (more preferably 410nm to 422nm, and even more preferably 412nm to 420nm), the hydrogel contact lenses containing one or two of the HEVL-absorbing vinyl monomers of the present invention are thought to significantly not block blue light (450nm to 495nm), and thereafter provide minimal changes in color perception, minimal reduction in color vision, minimal reduction in scotopic visual function, minimal reduction in contrast sensitivity in crepuscular and scotopic states, and minimal interruption of circadian sunlight.
[0060] In one embodiment, the present invention relates to formula (I) [ka] (In the formula, tBu is a tert-butyl group, R' is H or CH3, R1 is Cl or CF3, and L1 is a divalent C5-C6 alkylene group or -C2H4-(OC2H4) n -(wherein n is 1, 2, or 3) is a divalent group.

[0061] According to this aspect of the present invention, bond L1 has an extended spacer and (compared to those having a shorter L1, e.g., L1=CH2CH2CH2) may have higher solubility in 1-propanol. Furthermore, R1 has a Hammett substituent constant (σ) of about 0.23R (R1=Cl) or about 0.54R (R1=CF3).p It is an organic group having ) the electron-withdrawing ability of the substituent on the aromatic ring of benzotriazole (Hammett substituent constant, σ). p ) is thought to correlate with the wavelength of the absorption peak. The larger the electron-withdrawing characteristic (i.e., the larger the σ p ), the red shift of the absorption peak is large. When R1 is Cl or CF3, the monomer may have an absorption peak at approximately 364 nm or approximately 368 nm.

For example, R'=CH3, R1=CF3 and L1=C5H 10 The benzotriazole vinyl monomer of formula (II) can be synthesized by following the procedure shown in Figure 1. This synthetic route begins with the preparation of 2-tert-butyl-4-(5'-hydroxypentyloxy)phenol ("Compound 1") by reacting 5-chloro-1-pentanol with tert-butylhydroquinone, as described in U.S. Patent No. 4,716,234. Then, 4-trifluoromethyl-2-nitroaniline is converted to a diazonium salt ("Compound 2") according to the procedure described in U.S. Patent No. 8,585,938, and this is azo-coupled with Compound 1. The nitroazo intermediate ("Compound 3") is then reduced with glucose and zinc powder to close the benzotriazole ring and obtain the benzotriazole compound ("Compound 4"). In the final step, compound 4 is reacted with methacryloyl chloride according to the procedure described in U.S. Patent No. 4,716,234 to obtain 2-[2'hydroxy-3'-tert-butyl5'(5''-methacryloyloxy)pentyloxyphenyl]-5-trifluoromethyl-2H-benzotriazole ("compound 5").

[0066] The benzotriazole vinyl monomer of formula (II) can be prepared by a procedure similar to that of scheme II. For example, the benzotriazole vinyl monomer of formula (II) with R'=CH3, R2=COOCH3 and L2=C3H6 can be synthesized by the procedure shown in Figure 2. This synthetic route begins with the preparation of 2-tert-butyl4-(3'-hydroxypropoxy)phenol ("compound 6") by reacting 3-chloro-1-propanol with tert-butylhydroquinone. Methyl4-amino-3-nitrobenzoate is then converted to a diazonium salt ("compound 7"), which is azo-coupled with compound 6. The nitroazo intermediate ("compound 8") is then reduced with glucose and zinc powder to close the benzotriazole ring and obtain the benzotriazole compound ("compound 9"). In the final step, compound 9 is reacted with methacryloyl chloride to obtain methyl 2-(3-(tert-butyl)-2-hydroxy-5-(3-(methacryloyloxy)propoxy)phenyl)-2H-benzotriazole-5-carboxylate ("compound 10").

[0090] Lens molds for manufacturing hydrogel contact lenses are well known to those skilled in the art and are used, for example, in casting or spin casting. For example, a mold (for casting) generally comprises at least two mold pieces (or parts) or mold halves, i.e., a first and a second mold half. The first mold half defines a first molding (or optical) surface, and the second mold half defines a second molding (or optical) surface. The first and second mold halves are configured to receive each other so that a lens-forming cavity is formed between the first molding surface and the second molding surface. The molding surfaces of the mold halves are the cavity-forming surfaces of the mold and are in direct contact with the polymerizable composition.
[0091] Mold halves can be formed by various methods, such as injection molding. Methods for manufacturing mold halves for casting contact lenses are generally well known to those skilled in the art. The method of the present invention is not limited to any particular method of forming a mold. In fact, any method of forming a mold can be used in the present invention. Mold halves can be formed by various techniques, such as injection molding or turning. Examples of preferred processes for forming mold halves are disclosed in U.S. Patent Nos. 4,444,711, 4,460,534, 5,843,446, and 5,894,002.
[0092] Virtually all materials known in the art for manufacturing molds can be used to manufacture molds for manufacturing contact lenses. For example, polymer materials such as polyethylene, polypropylene, polystyrene, PMMA, and Topas® COC grade 8007-S10 (a transparent amorphous copolymer of ethylene and norbornene, manufactured by Ticona GmbH in Frankfurt, Germany and Summit, New Jersey) can be used. Other materials that can transmit UV light, such as quartz glass and sapphire, may also be used.
[0093] In accordance with the present invention, polymerizable compositions can be introduced (distributed) into cavities formed by molds according to any known method.
[0094] After the polymerizable composition is distributed into the mold, it is polymerized (cured) to produce a contact lens. Crosslinking can be initiated thermally or chemically to polymerize (cure) the polymerizable components in the polymerizable composition.
[0095] Thermal polymerization is conveniently carried out at a temperature of, for example, 25 to 120°C, preferably 40 to 100°C. The reaction time can vary over a wide range, but is conveniently, for example, 30 minutes to 4 hours, or preferably 1 to 2 hours. It is advantageous to degas the components and solvent used in the polymerization reaction beforehand and carry out the copolymerization reaction under an inert atmosphere, for example, a nitrogen or argon atmosphere.
[0096] In that case, chemical beam polymerization can be induced by chemical beams, such as visible light of an appropriate wavelength (e.g., ≥450 nm).
[0097] After the curing step, the steps of mold demolition (i.e., separating the male mold half from the female mold half with the hydrogel contact lens attached to one of the male and female mold halves) and lens removal (i.e., removing the hydrogel contact lens from the mold half to which the lens is attached) are carried out according to any technique known to those skilled in the art.
[0098] After removing the molded hydrogel contact lens, it is typically extracted using an extraction medium well known to those skilled in the art. The extraction liquid medium is any solvent capable of dissolving the diluent, unpolymerized polymerizable material, and oligomer in the lens precursor. Water, any organic solvent known to those skilled in the art, or mixtures thereof can be used in this invention.
[0099] The extracted hydrogel contact lens can then be hydrated by any method known to those skilled in the art.
[0100] The extracted and / or hydrated hydrogel contact lenses may be subjected to further processes such as surface treatment, packaging in lens packages using packaging solutions well known to those skilled in the art, and sterilization such as autoclaving at 118-124°C for at least about 30 minutes.
[0101] Lens packages (or containers) are well known to those skilled in the art for autoclaving and storing soft contact lenses. Any lens package may be used in the present invention. Preferably, the lens package is a blister package comprising a base and a cover, the cover being removably sealed to the base, and the base comprising a cavity for receiving a sterile packaging solution and the contact lens.
[0102] Hydrogel contact lenses are packaged in individual packages, sealed, and sterilized (for example, by autoclaving at 120°C or higher for at least 30 minutes under pressure) before being distributed to the user. Those skilled in the art will be well aware of the methods for sealing and sterilizing lens packages.

[0178] The foregoing disclosure will enable those skilled in the art to implement the invention. Various modifications, changes, and combinations of the various embodiments described herein are possible. References to the following examples are proposed to enable the reader to better understand the particular embodiments and their advantages. This specification and the examples are intended to be illustrative. [Examples]
[0179] Example 1 Measurement of oxygen permeability coefficient Unless otherwise specified, the oxygen permeability coefficient (Dk / t) of the lens and lens material, and the intrinsic (or edge-corrected) oxygen permeability (Dk i or Dk c ) is measured according to the procedure described in ISO 18369-4.
[0180] equilibrium moisture content The equilibrium water content (EWC) of contact lenses is measured as follows:
[0181] The amount of water (expressed as a weight percentage) present in a hydrated hydrogel contact lens, fully equilibrated in physiological saline, is measured at room temperature. The lenses are quickly stacked, wiped with a cloth, and then the lens stack is transferred to an aluminum pan on an analytical balance. Typically, there are 5 lenses per sample pan. The hydrated weight of the pan + lenses is recorded. The pan is covered with aluminum foil. The pan is dried in a laboratory oven at 100±2°C for 16-18 hours. The pan + lenses is removed from the oven and cooled in a desiccator for at least 30 minutes. Only one pan is removed from the desiccator, and the aluminum foil is discarded. The pan + dried lens sample is weighed on an analytical balance. Repeat for all pans. The wet and dry weights of the lens sample can be calculated by subtracting the weight of the empty weighing pan.
[0182] modulus of elasticity The elastic modulus of a contact lens is measured using the MTS Insight instrument. The contact lens is first cut into 3.12 mm wide strips using a Precision Concept two-stage cutter. Five thickness values are measured within a gauge length of 6.5 mm or less. The strips are mounted on the instrument grip and immersed in PBS (phosphate-buffered saline) at a controlled temperature of 21 ± 2°C. Typically, a 5N load cell is used for the test. A constant force and velocity are applied to the sample until it breaks. Force and displacement data are collected using TestWorks software. The elastic modulus value is calculated by TestWorks software and is the slope or tangent of the stress-to-strain curve near zero elongation in the elastic deformation region.
[0183] Transmittance The contact lens is manually placed in a specially manufactured sample holder that maintains the lens shape as if it were on the eye. This holder is then immersed in a 1 cm path length quartz cell containing phosphate-buffered saline (PBS, pH approximately 7.0-7.4) as a reference. A UV / visible spectrophotometer, such as a Varian Cary 3E UV-Visible spectrophotometer equipped with a LabSphere DRA-CA-302 beam splitter, can be used for this measurement. Percentage transmission spectra are collected in the wavelength range of 250-800 nm, and %T values are collected at 0.5 nm intervals. This data is transferred to an Excel spreadsheet and used to determine whether the lens matches Class 1 UV absorbance. The transmittance is calculated using the following formula: UVA%T=315nm~380nm average % transmittance x 100 UVB%T=280nm~315nm average % transmittance x 100 HEVL%T=380nm~450nm average % transmittance x 100.

"G1" represents the di-methacryloyloxypropyl-terminated polysiloxane (Mn approximately 7.5-8.1 kg / mol, OH content approximately 1.25-1.55 mol / g) shown in formula (A) below. [ka]
[0185] Example 2 This example uses HEVL-absorbing vinyl monomer. [ka] (In the formula, L1 is -(CH2)3- or -(CH2)2-O-(CH2)2-) This shows the correlation between the melting point and solubility.
[0186] A correlation has been reported between lower melting points and compound solubility (Bathori, NBActa Cryst., 2014, A70, C990).
[0187] When linker L1 is extended from -(CH2)3- in UV28 to -(CH2)2-O-(CH2)2- in UV35, the melting points are found to decrease significantly from 112-113°C to 62-65°C, respectively. As expected, the solubility in 1-propanol improves to >4.0 mg / mL (Table 1). However, the UV / visible absorption profiles of UV28 and UV35 are equivalent, as shown in Figure 3.
[0188] [Table 1]
[0189] Example 3 Preparation of lens formulations Two types of lens formulations are prepared to have the compositions shown in Table 2.
[0190] [Table 2]
[0191] All components listed in Table 2 (excluding the germanium-based photopolymerization initiator) are added to an amber vial. Then, TEB-Ge or BMBDE-Ge (whose structures are listed in Table 3) is added to the vial under yellow light, and all components are mixed for 30 minutes in a water bath preheated to 40°C. After all solids have dissolved, the mixture is filtered through a glass microfilter (5.0 μm Millex®-SV filter).
[0192] [Table 3]
[0193] PAA coating solution. The polyacrylic acid (PAA) coating solution is prepared by dissolving PAA (MW: 450 kDa, from Lubrizol) in a predetermined amount of 1-propanol (1-PrOH) to a concentration of approximately 0.44% by weight, and adjusting the pH to approximately 2.0 with formic acid.
[0194] Preparation of in-package coating solution (IPC physiological saline). Poly(AAm-co-AA)(90 / 10) partial sodium salt (approximately 90% solids, poly(AAm-co-AA)90 / 10, Mw200,000) is purchased from Polysciences, Inc. and used as received. Polyamidoamine epichlorohydrin (PAE) (Kymene, azetidinium content 0.46 as analyzed by NMR) is purchased as an aqueous solution from Ashland and used as received. IPC saline is prepared by dissolving approximately 0.07% w / w poly(AAm-co-AA) (90 / 10) and approximately 0.10% PAE (initial azetidinium millimolar equivalent of approximately 8.8 mmol) in phosphate-buffered saline (PBS) (approximately 0.044 w / w% NaH2PO4·H2O, approximately 0.388 w / w% Na2HPO4·2H2O, approximately 0.79 w / w% NaCl) and adjusting the pH to 7.2-7.6. Next, the IPC is heat-pretreated at approximately 60°C for approximately 6 hours (heat pretreatment). During this heat pretreatment, the poly(AAm-co-AA) and PAE are partially crosslinked with each other (i.e., not all azetidinium groups of the PAE are consumed), forming a water-soluble and heat-crosslinkable hydrophilic polymer material containing azetidinium groups within a branched polymer network in the IPC saline. After heat pretreatment, the IPC is cooled to room temperature and filtered through a 0.22 micron PES membrane filter.
[0195] Lens manufacturing (Lightstream) The lenses are prepared by casting from the lens-forming composition prepared above in a reusable mold (half female mold made of quartz and half male mold made of glass) similar to the molds shown in Figures 1-6 of U.S. Patent No. 7,384,590 and No. 7,387,759 (Figures 1-6). The lens compound in the mold is subjected to a pressure of 50 mW / cm². 2The lenses were cured for 30 seconds with 452 nm (BMBDE-Ge formulation) or 464 nm (TEB-Ge formulation) LED light at a total intensity. After demolding and lens removal, the cast contact lenses were extracted and coated by immersion in the following series of baths: three methyl ethyl ketone (MEK) baths (approximately 22 seconds, 78 seconds, and 224 seconds each), a DI water bath (56 seconds), the PAA dip solution prepared above (44 seconds), a 50 / 50n-propanol / water bath (56 seconds), four DI water baths (56 seconds each), and then equilibrated in PBS solution.
[0196] The resulting silicone hydrogel contact lenses are packaged / sealed in polypropylene lens packaging shells (or blisters) containing 0.65 mL of IPC saline solution prepared above (one lens per shell), and autoclaved at 121°C for 45 minutes.
[0197] Example 4 Preparation of lens formulations The lens compound (4-1) is prepared to have the composition shown in Table 4.
[0198] [Table 4]
[0199] Lens manufacturing (thermosetting) Lenses are prepared by casting from the polymerizable compositions shown in Table 4. The polymerizable composition is placed in a polypropylene mold and heat-cured in an oven with the following curing profile: heating from room temperature to 55°C at a rate of approximately 7°C / min, holding at 55°C for approximately 30 minutes, heating from 55°C to 80°C at a rate of approximately 7°C / min, holding at 80°C for approximately 30 minutes, heating from 80°C to 100°C at a rate of approximately 7°C / min, and holding at 100°C for approximately 30 minutes.
[0200] After release, the cast SiHy contact lenses are extracted with a PAA coating solution at 40 °C for 30 minutes and at 40 °C for 90 minutes, and then rinsed in PB (phosphate buffer containing about 0.077 wt% NaH2PO4·H2O and about 0.31 wt% Na2HPO4·2H2O) for 15 minutes. The resulting silicone hydrogel contact lenses are packaged / sealed in a polypropylene lens packaging shell (or blister) (one lens per shell) together with 0.65 mL of IPC physiological saline, and then autoclaved (sterilized) at 121 °C for 45 minutes.
[0201] Example 5 The properties of the lenses prepared in Examples 3 and 4 are evaluated and the results are reported in Table 5.
[0202]
Table 5
[0203] Figure 4 shows the UV / visible transmission spectra of the contact lenses obtained from lens formulations 3-2 and 4-1.
[0204] Example 6 This example reports a study on the solubility and stability of UV35.
[0205] Preparation of lens formulations Four lens formulations are prepared to have the compositions shown in Tables 6 and 7.
[0206]
Table 6
Table 7
[0208] Mix 10g of the total formulation at room temperature for 1-2 hours. After the initial mixing, mix the Lightstream formulations (6-1 and 6-2) at 40°C for a further 1-2 hours. UV28 in the Lightstream control formulation (6-1) does not dissolve, and this formulation cannot be subjected to stability testing. Conversely, UV35 dissolves completely in Lightstream formulation 6-2 after stirring at 40°C for 30 minutes. Both benzotriazole UV28 and UV35 dissolve in the thermosetting formulations (6-3 and 6-4). The formulations are subjected to storage stability testing, and the results are shown in Table 8. Tests are performed under room temperature and refrigerated (3°C) conditions.
[0209] [Table 8]
[0210] Example 7 In this example, four HEVL-absorbing vinyl monomers listed in Table 9 are used. They can be represented by the following structural formulas. [ka]
[0211] [Table 9]
[0212] Table 9 shows that the HEVL absorption peak of HEVL-absorbing vinyl monomers can be shifted to longer wavelengths by changing the electron-withdrawing or electron-donating ability of substituents R on the aromatic ring.
[0213] The effect of changes in the electron-withdrawing or electron-donating ability of substituents on absorption peaks has been reported to be expressible using linear free energy relations, particularly the Hammett equation (Jaffe, HHChem. Rev., 1953, 53, 191).
[0214] Table 9 shows the empirical substituent parameters (σ para This shows the correlation between the shift in absorbance peaks and the value of the absorbance peak.
[0215] Figure 5 shows the UV-VIS absorption spectra of dilute solutions of four HEVL-absorbing benzotriazole-containing vinyl monomers in 1-propanol.
[0216] Generally, the higher the electron-withdrawing property, the larger the red shift. In the case of UV40 (R = -C(O)OCH3), there may be some other factors that cause a significantly higher red shift than that predicted based on the value of the empirical substituent parameter (σ para ).
