Abstract
Description
Technical Field
[0001] The present disclosure relates to sialic acid derivatives and methods of using the same.
Background Art
[0002] Alzheimer's disease (AD) is a complex neurodegenerative disease accompanied by progressive cognitive impairment commonly seen in the elderly. In 2006, the number of AD patients worldwide was 26.6 million, but the number of AD is expected to quadruple by 2050 (Ziegler-Graham K., et al. “Forecasting the global burden of Alzheimer’s disease,” Alzheimers Dement. 2007;3:186-91). AD consists of early-onset AD (EOAD) and late-onset AD (LOAD). LOAD, which accounts for the majority of AD, is the result of the interaction between environmental factors and genetic factors (Lu Zy et al., “Spreading of Pathology in Alzheimer’s Disease,” Neurotox Res 2017;32:707-22).Among these, genes play an important role, and the heritability is estimated to be as high as 80% (Gatz M.et al., “Role of genes and environments for explaining Alzheimer disease,” Arch Gen Psychiatry 2006;63:168-74; Palotas A,et al. “Candidate susceptibility genes in Alzheimer’s disease are at high risk for being forgotten--they don’t give peace of mind,” Curr Drug Metab 2006;7:273-93; Antoniades D.et al., “The role of reelin gene polymorphisms in the pathogenesis of Alzheimer’s disease in a Greek population,” J Biol Regul Homeost Agents 2011;25:351-8; Wang L.Z.et al., “Association between late-onset Alzheimer’s disease and microsatellite polymorphisms in intron II of the human toll-like receptor 2 gene,” Neurosci Lett 2011;489:164-7). So far, the apolipoprotein E (APOE) gene has been recognized as the only gene that increases the risk of LOAD, but this gene accounts for only 27.3% regarding the AD onset risk (Hollingworth P. et al. “Common variants in ABCA7, MS4A6A / MS4A4E, EPHA1, CD33 and CD2AP are associated with Alzheimer’s disease,” Nat Genet 2011;43:429-35; Jayadev S. et al., “Alzheimer’s disease phenotypes and genotypes associated with mutations in presenilin 2,” Brain 2010;133:1143-54; Alzheimer’s Association “2015 Alzheimer’s disease facts and figures.” Alzheimers Dement 2015;11:332-84; Liu Y. et al., “Multiple Effect of APOE Genotype on Clinical and Neuroimaging Biomarkers Across Alzheimer’s Disease Spectrum,” Mol Neurobiol 2016;53:4539-47). Therefore, further efforts are needed to search for risk genes other than APOE.
[0003] Preclinical evidence reported by two research groups supports the potential role of the sialic acid-binding site of CD33 and its relationship with microglial cell activation and AD. Using CD33 ligands bound to microparticles, it was found that the uptake of amyloid-β (Aβ) by microglial cells increased (Miles L.A. et al., “Small Molecule Binding to Alzheimer Risk Factor CD33 Promotes Aβ Phagocytosis,” iScience 2019;19:110 - 118). This result was reported to have been confirmed using CD33 ligands conjugated to lipids and subsequently incorporated into liposomes (Bhattacherjee A. et al., “Increasing phagocytosis of microglia through targeting CD33 with liposomes displaying glycan ligands,” J Controlled Release 2021;338:680 - 693). These results provide good evidence that ligands that bind strongly to the sialic acid-binding site on CD33 would promote the clearance of Aβ and are thus promising therapies that could affect AD.

Mode for Carrying Out the Invention
[0012] Definitions The following are the definitions of the terms used in this application.
[0013] As used herein, the singular terms "a," "an," and "the" include references to the plural unless the context clearly dictates otherwise.
[0014] The phrase "and / or" as used herein means "either or both" of the elements so joined conjunctively, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Thus, as a non-limiting example, "A and / or B" when used in conjunction with open-ended language such as "comprising" may, in some embodiments, refer to only A (optionally including elements other than B); in other embodiments, it may refer to only B (optionally including elements other than A); in still other embodiments, it may refer to both A and B (optionally including other elements), and so on.
[0015] As used herein, "at least one" means one or more of the elements in a list of elements, but does not necessarily include at least one of every element specifically listed in the list of elements, and does not exclude any combination of elements in the list of elements. This definition also allows that, regardless of whether or not it is related to specifically identified elements, elements other than those specifically identified in the list of elements referred to by the phrase "at least one" may optionally be present. Thus, by way of non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B", or, equivalently "at least one of A and / or B") may, in one embodiment, refer to at least one A, optionally including two or more, in the absence of B (and optionally including elements other than B); in another embodiment, it may refer to at least one B, optionally including two or more, in the absence of A (and optionally including elements other than A); in yet another embodiment, it may refer to at least one A, optionally including two or more, and at least one B, optionally including two or more (and optionally including other elements), and so on.
[0016] When a number is recited, whether alone or as part of a numerical range, it should be understood that the number can vary by up to 10% above and below the recited value.
[0017] As used herein, "optionally substituted" is synonymous with the phrase "substituted or unsubstituted". In general, the term "substituted", whether or not preceded by the term "optionally", refers to replacement of a hydrogen group in a given structure by a specified substituent group. Unless otherwise indicated, an "optionally substituted" group may have substituents at each position where the group is substitutable, and when two or more positions in any given structure may be substituted by two or more substituents selected from the specified groups, the substituents may be the same or different at each position. Combinations of substituents contemplated by the present disclosure result in the formation of stable or chemically realizable compounds.
[0018] The term "isotopologue" refers to species that differ only in their isotopic composition with respect to a chemical structure. In addition, unless otherwise specified, the structures depicted herein are also intended to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, a compound having the present structure except that hydrogen is replaced by deuterium or tritium, or carbon is replaced by 13C or 14C, is within the scope of the present disclosure.
[0019] Unless otherwise indicated, the structures illustrated herein are also intended to include all isomeric forms of the structure, such as racemic mixtures, cis / trans isomers, geometric (or conformational) isomers, such as (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers. Thus, geometric and conformational mixtures of the present compounds are within the scope of the present disclosure. Unless otherwise specified, all tautomeric forms of the compounds of the present disclosure are within the scope of the present disclosure.
[0020] The term "tautomer" as used herein refers to one of two or more isomers of a compound that exist together in equilibrium and are readily interchangeable by the migration of atoms, such as hydrogen atoms, or groups, within the molecule.
[0021] "Stereoisomer", as used herein, refers to enantiomers and diastereomers.
[0022] As used herein, "deuterated derivative" refers to a compound that has the same chemical structure as the reference compound, but in which one or more hydrogen atoms have been replaced by deuterium atoms ("D" or "2H"). It will be recognized that there may be some variation in the natural isotope abundance of synthetic compounds depending on the origin of the chemical materials used in their synthesis. The concentration of the naturally abundant stable hydrogen isotope is small and negligible compared to the degree of stable isotope substitution of the deuterated derivatives described herein, notwithstanding this variation. Thus, unless otherwise specified, when reference is made to a "deuterated derivative" of a compound of the present disclosure, at least one hydrogen has been replaced by deuterium to a level far exceeding its natural isotope abundance (which is typically about 0.015%). In some embodiments, the deuterated derivatives of the present disclosure have an isotope enrichment factor of at least 3500 (52.5% deuterium incorporation for each specified deuterium), at least 4500 (67.5% deuterium incorporation), at least 5000 (75% deuterium incorporation), at least 5500 (82.5% deuterium incorporation), at least 6000 (90% deuterium incorporation), at least 6333.3 (95% deuterium incorporation), at least 6466.7 (97% deuterium incorporation), or at least 6600 (99% deuterium incorporation) for each deuterium atom.
[0023] The term "isotope enrichment factor", as used herein, means the ratio of the isotope abundance of the specified isotope to its natural abundance.

[0125] 8. General preparation procedure of macrocyclic analogs of neuraminic acid (Compound AN). Scheme 12 [Chemical formula] An example of the synthetic route leading to compounds in the macrocyclic series is shown in Scheme 12. Using either Boc-protected D- or L-serine methyl ester (AF) as the starting material, by Mitsunobu conditions, followed by ozonolysis of the terminal olefin, subsequent reduction to alcohol, and finally formation of an allyl ether protected with t-butyldimethylsilyl, Compound AG is obtained (where n equals 1). Reduction of the ester under standard hydride conditions, allylation using similar Mitsunobu conditions, and desilylation give primary alcohol AH (n = 1). Next, commercially available phenols such as AI can be coupled with AH under standard Mitsunobu conditions, followed by deprotection of the chiral amine, condensation with the appropriate acid AJ, and ester hydrolysis to give Compound AK. Then, after condensing amine compound AL, prepared from the reduction of the azide of Compound F (Scheme 1, R = Boc), with AK, and subsequently acylating all free hydroxyl groups, fully protected intermediate compound AM is obtained. By modified Hoyveda-Grubbs ring-closing metathesis with AM, followed by Boc removal, condensation with a selected acid, and finally hydrolysis of the terminal C-1 ester using hydroxide, the desired macrocycle AN containing an olefin is obtained. The saturated analog of AN can be obtained using simple hydrogenation conditions.
[0126] 9. Alternative preparation procedure of macrocyclic analogs of neuraminic acid (Compound AV). Scheme 13 [Chemical formula] A similar procedure for preparing the macrocyclic compound is shown in Scheme 13. Starting from 4-hydroxybenzoic acid AO, first, the formation of an ether under weakly basic conditions, hydrolysis of the undesired ester formed by the ether formation reaction, formation of a methyl ester by the addition of diazomethane, and Boc deprotection of the terminal amine allow for the easy preparation of the amino ether compound AQ. Condensation of AQ with a suitable ester AR containing a terminal olefin, followed by ester hydrolysis, gives the compound AS. Next, after condensing AS with AL, subsequent transesterification with a benzyl ester and then protection of the hydroxyl group with acetyl gives AT. Ring-closing metathesis of AT, followed by Boc removal, condensation with the acid of choice AU, and then final debenzylation using a hydroxide gives the desired macrocycle AV containing an olefin. Final debenzylation using hydrogenolysis conditions provides the saturated macrocycle AV.
