Description

[Technical Field]

[0001] The present invention relates to a branched multi-hydroxyl-protected oligomer, a linker formed by binding to the branched multi-hydroxyl-protected oligomer, and a branched multi-hydroxyl-protected oligomer formed by deprotecting the linker. [Background technology]

[0002] Pterostilbene, resveratrol, and other polyphenols are known to have antioxidant and anti-inflammatory properties, as well as to improve skin elasticity. However, they are poorly water-soluble, and suffer from problems such as inconsistent mixing and precipitation over time. Glycosylation, in which sugar components are chemically linked to aglycones, is known as a method for improving the water solubility of poorly water-soluble compounds. However, this requires combining multiple monosaccharides to achieve sufficient water solubility, and the hydroxyl groups of the monosaccharides must also be protected, which can be costly.

[0003] Another known method for improving water solubility is multi-hydroxylation, which involves introducing multiple hydroxyl groups. Examples of multi-hydroxylation include polyethylene glycol (PEG), polyglycerol (PGL), and branched oligomer (BGL). These multi-hydroxylation methods offer significant advantages over glycosylation in terms of raw material availability and cost. As shown in the formula below, there is only one type of PEG, but linear and semi-linear PGLs are known, and there are multiple types of BGLs depending on the number of branches.

[0004] [ka] [wherein X is a general representation of a functional group that links to a poorly water-soluble target, and n is an integer of 1 or greater.]

[0005] PEG, including its monomers and dimers, is highly toxic, and only oligomers exceeding several dozen in number can fully exhibit water solubility. PGL contains numerous uncontrollable asymmetric carbon atoms, making it difficult to maintain reproducibility in compound production, homogeneity, and quality assurance. Furthermore, because both PEG and PGL are produced by polymerization reactions, molecular weight variation is also an issue. Furthermore, glycosylation often results in uncontrollable stereochemistry at the sugar linkage (anomeric position), resulting in mixtures. On the other hand, BGL does not contain asymmetric carbon atoms, and a production method that allows molecular weight control has been established. BGL production is highly reproducible, enabling the production of quality-assured derivatives. However, drawbacks of BGL include the laborious process of selectively producing 1,3-protected glycerol at the first stage of production (Patent Document 1), and the multiple steps required to produce oligomers exceeding heptamers result in low yields (Non-Patent Document 1).

[Brief explanation of the drawings]

[0024] The branched multi-hydroxyl-protected oligomer of the present invention is represented by the following formula (1).

[0025] [ka] [In formula (1), X is at least one selected from the group consisting of groups represented by the following formula (2), and Y a ~Y dis at least one selected from the group consisting of P, T, G, and A represented by the following formula (3), where m is 1, m' is an integer of 1 to 3, n is an integer of 0 to 9, and n' is an integer of 0 to 27 (excluding the cases where the compounds represented by formula (1) are X-G1G1, X-G1G2, X-G1A1, and X-G1A2).

[0026] [ka]

[0027] [ka] [In formula (3), Z is at least one selected from the group consisting of a hydrogen atom, a protecting group, and a carbon skeleton; R a is at least one selected from the group consisting of a hydrogen atom and an alkyl group.

[0028] The branched multi-hydroxyl-protected oligomer of the present invention can be synthesized using a simple method with fewer reaction steps, and can be provided at low cost. Furthermore, as is clear from the water solubility evaluation results in the Examples described below, the branched multi-hydroxyl-protected oligomer of the present invention has the excellent advantage of being highly effective in improving the water solubility of target compounds, which are poorly water-soluble compounds. In contrast, glycosylation can be costly because it requires combining multiple monosaccharides to achieve sufficient water solubility and protecting the hydroxyl groups of the monosaccharides. Furthermore, with branched oligomers (BGLs), the first step in the production requires a laborious process of selectively producing glycerol protected at the 1,3-positions, which can be costly. Therefore, it can be seen that the adoption of the present invention is highly significant.

[0029] In the above formula (1), X is at least one selected from the group consisting of groups represented by the following formula (2), and is a reactive group used for bonding to a target compound. A substituent of the target compound reacts with X, and a conjugate formed by bonding the branched multi-hydroxyl-protected oligomer represented by formula (1) to the target compound can be suitably obtained.

[0035] Y in the above formula (1) a ~Y d is at least one selected from the group consisting of P, T, G, and A represented by the above formula (3), and Y a ~Y d may be the same or different. Y a ~Y d are connected to each other via Z in the above formula (3), and Z used for the connection is a carbon skeleton. That is, Z in -OZ is a carbon skeleton, and Y a ~Y dare connected to each other by an ether bond (-O-). The carbon skeleton is preferably a covalent bond, and may be a divalent hydrocarbon group.

[0036] In the above formula (1), m is 1 and m' is an integer of 1 to 3.

In the above formula (1), n ​​is an integer of 0 to 9, and n' is an integer of 0 to 27. Y, which is at least one selected from the group consisting of P, T, G, and A, represented by the above formula (3), b Y as many times as Z c and Y is at least one selected from the group consisting of P, T, G, and A represented by the formula (3). c Y as many times as Z d For example, Y b All of the Z's are Y's c may be bonded to Y c All of the Z's are Y's d may be bonded to Y. b One or more Z's and Y's c are combined to form Y b The remaining Z may be at least one selected from the group consisting of a hydrogen atom and a protecting group, and Y c One or more Z's and Y's d are combined to form Y c The remaining Z may be at least one selected from the group consisting of a hydrogen atom and a protecting group. b If all are P, there are 9 Zs, so the maximum number of n is 9. Similarly, if n is 9 and Y cIf all are P, there are 27 Zs, so the maximum number of n' is 27. Note that if both n and n' are 0, Y c and Y d This results in a structure in which

[0037] In the above formula (3), Z is at least one selected from the group consisting of a hydrogen atom, a protecting group, and a carbon skeleton, and as described above, Y a ~Y d are mutually linked via Z. The Z not used in the linkage is preferably at least one selected from the group consisting of a hydrogen atom and a protecting group. From the viewpoint of deprotecting the linked compound after obtaining the linked compound bound to the target compound, it is a preferred embodiment that the Z not used in the linkage is a protecting group.

[0043] The arylmethyl group is not particularly limited as long as it has a structure in which an aryl group is bonded to a methyl group, and examples thereof include a benzyl group and a 4-methoxybenzyl group.

[0044] As the group in which a plurality of Zs form a cyclic structure, in the case of P, T, G and A represented by the above formula (3), structures represented by the following formulas (3a) to (3d) are preferably used, respectively.

[0052] [ka] [In formula (1a), X, Y b ~Y d , Z, m, m', n, and n' are defined as in formula (1).

[0053] [ka] [In formula (1b), X, Y b ~Y d , Z, m, m', n and n' are the same as those in formula (1), and R a has the same meaning as in formula (3).

[0054] [ka] [In formula (1c), X, Y b ~Y d , Z, m, m', n, and n' have the same meanings as in formula (1) above (excluding the cases where the compounds represented by formula (1c) are X-G1G1, X-G1G2, X-G1A1, and X-G1A2).

[0055] [ka] [In formula (1d), X, Y b ~Y d , Z, m, m', n, and n' are defined as in formula (1).

[0056] In the above formula (1a), for example, m' is 1, n and n' are 0, and Y b The branched multi-hydroxyl-protected oligomer of the present invention has one of the simplest structures, which is represented by the following formula (1a') (X-P1P1, X-P1T1, X-P1G1, X-P1A1), in which X is P, T, G, or A represented by formula (3). The branched multi-hydroxyl-protected oligomer of the present invention is not limited to this structure.

[0057] [ka] [In formula (1a'), X is the same as defined in formula (1), and Z and R a has the same meaning as in formula (3).

[0058] The method for producing the branched multi-hydroxyl-protected oligomer of the present invention is not particularly limited. For example, as shown in the following reaction formula (I), a =Br) and an alcohol R represented by the following formula (4): 1 As shown in the following reaction formula (II), tribromide (X a =Br) and an alcohol R represented by the following formula (4): 1 It can also be produced by etherification with epichlorohydrin (Xb =Cl) and an alcohol R represented by the following formula (4): 1 Alternatively, the branched multi-hydroxyl-protected oligomer may be produced by a linkage reaction with —OH. Known methods are preferably used for these reactions. The halogen atom in Xa is preferably a bromine atom, a chlorine atom, or an iodine atom. The substituent X in the obtained branched multi-hydroxyl-protected oligomer is at least one selected from the group consisting of groups represented by formula (2), and can be converted to the desired substituent X by appropriately carrying out a tosylation reaction, a deallylation reaction, or the like.

[0062] [ka]

[0063] The obtained branched multi-hydroxyl-protected oligomer can be conjugated to a target compound. For example, when the substituent X in the branched multi-hydroxyl-protected oligomer represented by formula (1) is -Br or -OTs, a conjugate can be obtained by reacting it with the hydroxyl groups of the target compound, pterostilbene, as shown in the following reaction formula (IV). That is, a conjugate formed by conjugating a branched multi-hydroxyl-protected oligomer and a target compound is a preferred embodiment. The target compound is preferably a water-insoluble compound, and preferred examples of the water-insoluble compound include polyphenol compounds having hydroxyl groups, such as pterostilbene and resveratrol.

[0065] The branched multi-hydroxyl-protected oligomer to be bonded to the target compound may be a deprotected branched multi-hydroxyl-protected oligomer. However, from the viewpoint of efficient reaction, it is preferred to obtain a linker bonded to the target compound and then deprotect the linker. Known methods can be used for deprotection. As shown in the examples below, the protecting groups in the linker are deprotected to generate a large number of hydroxyl groups. As is clear from the water solubility evaluation results in the examples below, the branched multi-hydroxyl-protected oligomer of the present invention has a very high effect of improving the water solubility of the target compound, which is a poorly water-soluble compound. Therefore, a water solubility improver comprising a branched multi-hydroxyl-protected oligomer is a preferred embodiment. [Example]

[0307] Example 19 [Water solubility evaluation] The deprotected pterostilbene conjugates obtained in the Examples were evaluated for water solubility using the following method. The results are summarized in Figures 1 and 2. In Figures 1 and 2, the numbers in the ellipses for each compound represent the degree of water solubility as a molar ratio, with the water solubility of F1 (pterostilbene) (21 mg (0.0819 mmol) dissolved in 1 L) set at 1.0. The water solubility of F1 (pterostilbene) was determined using the value described in Sarah J. Bethune et al., Cryst. Growth Des. 2011, 11, 2817-2823. The water solubility of F1 glycoside (pterostilbene monoglycoside) was determined using the value described in Jose L. Gonzalez-Alfonso et al., Molecules 2018, 23, 1271.

[0308] [Compounds G119, G129, G139, H119 and H219] 1.0 g of the compound and 100 mL of ion-exchanged water were weighed into a round-bottom flask and heated with a heat gun for approximately 1 minute, taking care not to boil the mixture. The mixture was then returned to room temperature and allowed to stand. After 24 hours, the residue was removed by filtration, and the filtrate was concentrated under reduced pressure. The water solubility of each compound was calculated from the weight of the compound recovered from the filtrate.

[0309] [Compounds H129, H139, J119, J129, J139, J219, J229 and J239] A solution was prepared in a round-bottom flask using the compound and the amount of ion-exchanged water shown in Figure 1, and the water solubility of the compound was calculated. Because the compound was extremely water soluble, the water solubility limit could not be measured, but compared to the poorly water-soluble F1, its water solubility was an order of magnitude higher at more than 2 x 10^4.
