Definitions
- the present invention relates to the field of nucleic acid sequencing.
- the present invention relates to nucleotide analogs for sequencing.
- NGS sequencing has overcome the disadvantages of high cost and long sequencing time of Sanger sequencing, and has greatly promoted the application of gene sequencing technology.
- NGS sequencing has been deeply applied in prenatal screening, tumor diagnosis, tumor treatment, animal and plant breeding and other fields, driving the progress of science and technology and medicine.
- Nucleoside triphosphate (dNTP) analogs with reversible blocking groups are key raw materials in NGS sequencing. Due to the introduction of the reversible blocking group, the 3'-OH group in dNTP can be retained, which overcomes the shortcomings of Sanger sequencing and ensures the accuracy of base recognition. It can be said that nucleoside triphosphate analogs (dNTPs) with reversible blocking groups are the most critical technology in NGS sequencing. Nucleotides with cleavable linkers and detectable labels in NGS sequencing are the key to base detection.
- the present invention aims to develop a class of dNTP analogs with cleavable and detectable labels on the base or the 3'-OH of the nucleotide sugar ring for NGS sequencing.
- the general structural formula of the first class of dNTP analogs is shown in Figure 1.
- the bases have nucleotides that can be cleaved and detectably labeled, including 2'deoxyuridine triphosphate, 2'deoxycytidine triphosphate, 7-deoxyuridine triphosphate, and 7-deoxyuridine triphosphate.
- the sugar ring 3'-OH is connected with any reversible blocking group that is conventionally used in the art and has an excellent effect of being connected to the 3'-OH.
- the general structural formula of the second class of dNTP analogs is shown in Figure 2, and the 3'-OH of the sugar ring is reversibly blocked with detectably labeled nucleotides.

- polymerases such as DNA polymerases.
- the compounds of formula I, formula II, formula III, and formula B are introduced into the 3' end of the growing nucleic acid chain, since there is no free hydroxyl group (-OH) at the 3' position of the deoxyribose sugar of the compound, The polymerase will not be able to proceed to the next round of polymerization and the polymerization will be terminated. In this case, in each round of polymerization, one and only one base will be incorporated into the growing nucleic acid strand.
- the protective group (R') of the hydroxyl group (-OH) at the 3' position of the deoxyribose sugar of the compounds represented by the formula I, formula II, formula III and formula B can be removed and converted into a free hydroxyl group (- OH). Subsequently, a polymerase and compounds of formula I, formula II, formula III, and formula B can be used to perform the next round of polymerization on the growing nucleic acid chain, and a base is introduced again.
- the hydroxyl group (-OH) at the 3' position of the deoxyribose sugar of the compounds of formula I, formula II, formula III, and formula B can be reversibly blocked: when formula I, formula II, formula III, and formula B are shown in formula B
- the compounds When the compounds are incorporated into the 3' end of the growing nucleic acid chain, they will stop the polymerase from continuing to polymerize and terminate the further extension of the growing nucleic acid chain; After the contained blocking group is removed, the polymerase will be able to continue polymerizing the growing nucleic acid chain and continue to extend the nucleic acid chain.
- Detection can be performed by any suitable method, including fluorescence spectroscopy or other optical means.
- Preferred labels are fluorescent labels or fluorophores that emit radiation of defined wavelengths after absorbing energy.
- Many suitable fluorescent labels are known.
- Welch et al. (Chem. Eur. J. 5(3):951-960, 1999) disclose dansyl-functionalized fluorescent moieties, which can be used in the present invention.
- Zhu et al. (Cytometry 28:206-211, 1997) describe the use of fluorescent labels Cy3 and Cy5, which can also be used in the present invention.
- Prober et al. Science 238:336-341, 1987
- iF700 fluorescein, rhodamine (including TMR, Texas Red and Rox), alexa, fluoroboron, acridine, coumarin, pyrene, benzo Anthracene and anthocyanins.
- iF700 is a fluorescent marker commonly used in the art, for example, see Table 7 of US20180223358A1, and the fluorescent marker is commercially available.
- multiple labels can also be used in this application, such as a dual-fluorophore FRET cassette (Tet. Let. 46:8867-8871, 2000), a multi-fluorophore dendrimer system (J.Am.Chem.Soc.123:8101) -8108, 2001).
- fluorescent labels are preferred, other forms of detectable labels will be apparent to those of ordinary skill in the art.
- microparticles including quantum dots (Empodocles et al., Nature 399:126-130, 1999), gold nanoparticles (Reichert et al., Anal. Chem. 72:6025-6029, 2000) and microbeads (Lacoste et al., Proc.Natl.Acad.Sci USA 97(17):9461-9466, 2000) can also be used.
- Multicomponent labels can also be used in this application.
- Multicomponent labels are labels that rely on interaction with additional compounds for detection.
- the most commonly used multicomponent labeling in biology is the biotin-streptavidin system. Biotin is used as a label attached to nucleotides or modified nucleotides. Streptavidin alone was then added to allow detection to occur.
- Other multi-component systems can be used. For example, dinitrophenol has commercially available fluorescent antibodies for detection.
- modified nucleotide or nucleoside molecules can be made to carry the above-described detectable label, the affinity reagent can specifically recognize and bind to the epitope of the modified nucleotide or nucleoside molecule.
- the affinity reagent can specifically recognize and bind to the epitope of the modified nucleotide or nucleoside molecule.
- modified nucleotide or nucleoside molecules can be linked to the detectable labels described above.
- the linking group used is cleavable. The use of a cleavable linking group ensures that the label can be removed after detection if desired, which avoids any interfering signals with any subsequently incorporated labeled nucleotides or nucleosides.
- the linking group can be cleaved by any suitable method, including exposure to acids, bases, nucleophiles, electrophiles, free radicals, metals, reducing or oxidizing agents, light, temperature, enzymes, and the like. Linking groups discussed herein can also be cleaved using the same catalysts used to cleave protecting groups at bases. Suitable linking groups can be modified from standard chemical protecting groups as disclosed in Greene & Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons. Suitable cleavable linking groups for solid phase synthesis are also disclosed in Guillier et al. (Chem. Rev. 100:2092-2157, 2000).
- nucleoside cleavage site can be located at a position on the linking group that ensures that a portion of the linking group remains attached to the nucleoside after cleavage Acids or modified nucleotides remain attached.
- nucleotides in this application have utility in Sanger sequencing, second-generation high-throughput sequencing (NGS sequencing), and third-generation sequencing (single-molecule sequencing) because by using the methods described herein Reversible blocking nucleotide analogs allow for the individual detection of nucleotide types incorporated in sequencing.
- TBAF After condensation of the nucleoside with the acid DCC, TBAF removes the protecting group, and then uses the triphosphorylated triphosphate. After aminolysis, it is coupled with linker1, the trifluoroacetyl group is removed, and finally it is coupled with a fluorescent dye to obtain the product.
