AI Technical Summary
Existing technologies for forming multivalent protein drugs suffer from poor linker specificity, heterogeneous multimers, high cytotoxicity risk, and short half-life. Furthermore, in vaccine development, the design of high-valent antigens makes it difficult to activate B cells, resulting in an insufficient immune response.
The design employs a multimeric complex based on a mutually compatible nucleic acid backbone. Stable n-order multimers are formed through complementary base pairing of nucleic acid single strands. These multimers can then bind to protein drugs or antigens to form multivalent drugs or vaccines. Simulated annealing algorithms are used to optimize nucleic acid sequences to improve assembly efficiency and stability.
This method enables the efficient and stable multivalent formulation of protein drugs, prolongs their half-life and enhances their activity, strengthens the immunogenicity of vaccines, and forms uniform multivalent macromolecular complexes through a simple and flexible approach.

Abstract
Description
Technical Field
[0001] This invention relates to the field of biopharmaceuticals, specifically to methods for constructing and applying nucleic acid polymerization-mediated multivalent protein drugs and vaccines. Background Technology
[0002] For many biomolecules, their aggregation or multivalent state directly affects their activity and half-life in vivo. For example, the activation of most immune receptors involves receptor aggregation on the cell membrane, thereby activating downstream signaling pathways within the cell. Therefore, the natural ligands or antibodies of these receptors often significantly enhance their ability to activate receptors when they form multivalent or high-valent states. Additionally, some low-molecular-weight protein drugs (MW 40 kDa), such as cytokines, growth hormones, and synthetic peptides, have high renal clearance and short in vivo half-lives; these protein drugs can also increase their molecular weight and half-life by forming high-valent states.
[0003] Therefore, protein multivalent conversion is a promising technology in the biopharmaceutical field, and many methods exist. However, most chemical cross-linking methods suffer from poor linker specificity and heterogeneous linker polymers. Currently, the most widely used method is to produce proteins through cellular expression as multivalent fusion proteins. This involves fusing drug-functional protein regions with oligomer-forming proteins to create chimeras, such as Fc bivalent fusion proteins and GCN4 trivalent fusion proteins. While these fusion proteins can form uniform oligomers, their cellular expression levels and activity are often lower than the original protein drugs. Furthermore, the presence of the Fc region carries the risk of activating the immune system, inducing cytokine release, and causing cytotoxicity. Therefore, there is an urgent need in this field to develop a simple, flexible, and efficient method to convert validated protein drugs into homogeneous, highly specific multivalent proteins in a non-fusion protein manner.
[0004] Furthermore, protein multivalent presentation is also significant for vaccine development. Firstly, in B-cell-based vaccine design, activating B-cell receptors (BCRs) using viral or bacterial proteins as antigens is a crucial step. Like the immune receptors mentioned above, effective activation of BCRs requires receptor aggregation on the cell membrane; therefore, high-valent antigens have a clear advantage over monomeric antigens in activating B cells. Secondly, high-valent antigens are not necessarily single-antigen oligomers; they can contain different proteins from a particular virus or mutants and subtypes of the same protein from different viral strains. Thus, the presentation of diverse antigens can theoretically induce a polyclonal response in the host's immune system, generating a wider range of neutralizing antibodies. Summary of the Invention

[0080] Finally, this invention provides a highly optimized nucleic acid sequence library, including a set of nucleic acid sequences that are efficiently and accurately assembled into 2-5 polymers, for rapid and accurate self-assembly of the aforementioned drug or antigen units into multivalent macromolecular complexes.
[0081] the term Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those used in this invention. The same meaning as commonly understood by one of ordinary skill in the art. As used herein, when referring to a specific enumerated value, the term “about” means that the value can vary from the enumerated value by no more than 1%. For example, as used herein, the expression “about 100” includes all values between 99 and 101 (e.g., 99.1, 99.2, 99.3, 99.4, etc.).

[0086] L-nucleotides Left-handed nucleic acids (L-RNAs) are mirror images of naturally occurring right-handed nucleic acids (D-RNAs). They can be divided into left-handed DNA (L-DNA) and left-handed RNA (L-RNA). The left-handed (chiral center) is mainly located in the deoxyribose or ribose portion of the nucleic acid, exhibiting a mirror-image inversion. Therefore, left-handed nucleic acids cannot be degraded by the ubiquitous nucleases in blood plasma (such as exonucleases and endonucleases).
[0087] Preparation method 1. Design and preparation of L-nucleic acid chain frameworks According to the present invention, the L-nucleic acid framework is formed by two or more L-nucleic acid single strands through base pairing. The 5' or 3' end of each L-nucleic acid single strand is activated to a group that can be subsequently modified (e.g., NH2), and then one end of a linker (e.g., SMCC, SBAP, etc.) is coupled to the activated group on the L-nucleic acid single strand. The L-nucleic acid with the linker can be assembled into the desired L-nucleic acid framework. In another preferred embodiment, the activated functional group (e.g., aldehyde, maleimide, etc.) at the 5' or 3' end of the L-nucleic acid single strand is already included in the nucleic acid synthesis. After confirming that the L-nucleic acid with the linker can successfully self-assemble into a framework, the L-nucleic acid single strand with the linker can be coupled with an antibody for subsequent assembly. The L-nucleic acid framework of the present invention can be prepared essentially by the following steps.
[0088] 1.1 Design of rapidly self-assembled L-nucleic acid single strands Determine the required number of multivalents, n (e.g., trimers, tetramers); determine the required number of L-nucleotide single strands, n, based on the number of multivalents, n; design the corresponding number of L-nucleotide single strand sequences, and adjust the stability of the target nucleic acid framework by optimizing base pairing to reduce the possibility of non-specific pairing between nucleic acid strands. Details of nucleic acid sequence design are described in the invention description and embodiments.
[0089] 1.2 Activation of L-DNA or L-RNA Activation of L-nucleotides involves modification of their 5' (X1) or 3' (X3) end active groups and subsequent conjugation with linkers. Modification of the active groups can be custom-made by nucleic acid synthesis companies; the linkers generally possess bifunctional groups, meaning one end can couple to the active group of the nucleic acid, and the other end can be linked to specific sites on the protein (such as NH3, SH).
[0090] According to a preferred embodiment of the present invention, all L-nucleotides constituting the framework are modified with an aldehyde at their 5' ends, thereby completing the activation of the L-nucleotides and enabling subsequent coupling to the N-terminus of the protein. -amine.
[0091] 2. Preparation method of protein-L-nucleic acid complex First, the 5' or 3' end of the L-nucleic acid is modified with an aldehyde. Then, under low pH (5-6) conditions, the aldehyde group of the L-nucleic acid is specifically linked to the N-terminus NH3 of the protein through a reductive amination reaction.

R1 and R2 are 14-16 bases in length; X1 and X3 have a length of 0-5 bases; X2 has a length of 0-3 bases and a sequence of A, AA, AGA or AAA; In this process, R1 of a nucleic acid sequence forms a target pair with R2 of a different nucleic acid sequence, while R2 of a nucleic acid sequence forms a target pair with R1 of another nucleic acid sequence.
[0096] In this invention, self-pairing of any region of the nucleic acid sequence is considered non-target pairing and should be avoided in the design.
[0097] Preferably, the nucleic acid sequence of the present invention can be designed or optimized using a computer algorithm of Simulated Annealing (SA).
[0098] The computer algorithm described above calculates the free energy of the DNA double-stranded structure formed by the target pairing. Minimize, while removing non-target pairs maximize; Specifically, the stability of a DNA double-stranded structure depends on the nearest neighbor base pairs in the sequence; any Watson-Crick DNA double-stranded structure may contain 10 different nearest neighbor interactions, and these paired interactions are: AA / TT; AT / TA; TA / AT; CA / GT; GT / CA; CT / GA; GA / CT; CG / GC; GC / CG; GG / CC; More specifically, the 10 base pairs mentioned above The value, at any temperature, can be expressed through enthalpy. ) and entropy The enthalpy, entropy, and free energy data for the 10 sequences were calculated. Table 1 shows the enthalpy, entropy, and free energy data for the 10 sequences.

For a given base sequence, this model predicts based on the nearest neighbor base pairs. The calculation of its melting temperature involves enthalpy. ) and entropy The calculation method is as follows: (1) Where R is a constant (1.987 cal K). -1 mol -1 ), CT is a chain concentration given as 0.1 µM, It is the entropy value of the DNA double strand at a given sodium ion concentration. It is the enthalpy value under given conditions.
[0103] Simulated annealing is a general probabilistic algorithm, a method for approximating optimization problems based on the Monte Carlo approach. It aims to find an approximate optimal solution within a large search space within a given time. The idea behind simulated annealing originates from the annealing process of solid materials in physics: the solid is first heated sufficiently, then slowly cooled. During heating, the internal energy of particles within the solid increases due to free movement. As the temperature gradually decreases, the particles tend to become more ordered, reaching an equilibrium state at each temperature. If the rate of temperature decrease is slow enough near the freezing point, the ground state is reached, and the internal energy is minimized. According to the Metropolis criterion, particles at temperature... T The probability of reaching equilibrium is ,in E For temperature T Internal energy at that time To change the amount, K This is the Boltzmann constant. A similar process exists for combinatorial optimization problems, where the microscopic state of the solid is considered. i The simulation is a solution X, and the objective function is equivalent to the state. i Internal energy of time and with control parameters T Simulate solid temperature. For T For each value, the iterative process of "generating a new solution → calculating the difference in the objective function → determining whether to accept → accepting / discarding" is repeated, and the values are gradually reduced. T The algorithm accepts poor solutions to a limited extent during the iteration process according to the Metropolis criterion, and the probability of accepting poor solutions gradually approaches 0, so that the algorithm can find the global optimal solution as much as possible when it terminates.
[0104] In this invention, the free energy of the non-target pairing regions between multimeric nucleic acid single strands is simulated as internal energy. While ensuring the free energy and dissociation temperature of the target pairing regions between nucleic acid single strands, the free energy of the non-target pairing regions is optimized through iterative simulated annealing algorithms. Finally, the optimized single strands are more conducive to multimeric assembly. The optimization objective function used is as follows: For sequence and sequence Non-target pairing free energy The sum of the free energies of non-target pairings among all sequences is negative; a larger value of this sum is more beneficial for reducing non-target pairings. Therefore, the objective function is constructed based on the idea of minimizing energy using a degenerate algorithm. Previously, a negative sign was added, converting it to a positive number. A smaller value is more conducive to reducing non-target pairings.
[0105] A flowchart of a representative algorithm of the present invention is shown below. Figure 2 As shown.
[0106] In this invention, the simulated annealing algorithm introduces a random factor. In each iteration, it will accept a solution that is worse than the current one with a certain probability. Therefore, it may escape the local optimum and reach the global optimum.

This is to find the set The two sequences that have the greatest impact on target pairing in non-specific pairing and Then according to Random selection of non-target pairing regions or An update was performed, resulting in a new nucleic acid sequence. The dissociation temperature of the paired regions of this nucleic acid sequence was then examined. Is the temperature greater than 54℃, and is the free energy of the pairing region ( Is it less than -29 kcal / mol? If the dissociation temperature and pairing region free energy have not been reached... The constraints are then repeatedly updated if the dissociation temperature and the pairing region free energy are reached. The constraints of ) are applied according to the base pairing principle. The sequence is updated, resulting in a new set of sequences. If, after fifteen updates, the resulting new nucleic acid sequence still fails to reach the dissociation temperature and pairing region free energy... To prevent infinite loops, the set...

Based on the Metropolis criterion, the probability is calculated. At the same time, randomly generated , ,if If the solution is good, accept the worsened solution; otherwise, reject it. Finally, the initial annealing temperature decreases to 0.98, generating a new solution, until the annealing termination temperature is reached, resulting in the optimized sequence set. .
[0116] The optimized sequences in Table 2_1 were obtained through the above algorithm. The purpose of the 5' end A in each sequence is for the modification of active groups and subsequent coupling with linkers.

[0118] The specific implementation steps for optimization are as follows: Sequence initialization: Initialize the paired sequence according to the parameters. Based on complementary base pairing, , , and Eight sequences are processed as follows Figure 1 The concatenation shown in (B) ultimately yields the initialization sequence set. During the tetramer experiment, a fixed nuclear structure was found to effectively improve the assembly efficiency of nucleic acid sequences. Based on nucleic acid sequence formula 1, nucleic acid sequence W2 was developed, which has the structure of formula 4: W2=X1-Q1-C1-X2-C2-Q2-X3 (4) C1 and C2 are the fixed core structure parts, and Q1 and Q2 are sequences other than the fixed core structure.
[0119] Table 3 Nucleic acid sequences containing fixed nuclear structures , , and New solution generation: Same as in Example 1. The difference is that if a fixed core structure is used, the update does not include the fixed core structure portion; parameter constraints must be strictly adhered to, and the dissociation temperature of the new nucleic acid sequence pairing region (…) The temperature should be greater than 52℃, and the free energy of the pairing region should be ( It is less than -27.4 kcal / mol.
[0120] Optimization judgment: Same as the optimization judgment in Example 1.
[0121] Table 4_1 shows the optimized sequences obtained through the above algorithm, and their specific pairing diagram is as follows: Figure 5 As shown in Figure 6, the broken-line graph of the unpaired target free energy during the optimization process of the tetramer optimized sequence is presented. This invention seeks to avoid affecting the free energy of the optimized sequence without adding connectives when connecting elements are included. This has a significant impact, regardless of whether the free energy of the sequence is optimized by adding connectives. The sum of the matrices was maximized. Therefore, during the optimization process, the objective function value of the sequence without the addition of linker optimization was statistically analyzed, and only the sequence with the addition of linker optimization was subjected to final detection. The corresponding nucleic acid backbone was then used to run gel electrophoresis. Figure 7 As can be seen, Lane 15 is a band of artificially designed tetramers, which exhibits a tailing phenomenon, while Lane 16 is the sequence after algorithm optimization. , , and The main band formed is around 100 bp, indicating the formation of a tetramer and exhibiting extremely high stability.
[0122] The above tetramer assembly steps primarily optimize the non-specific pairing free energy between sequences, while the secondary structures formed by the sequence folding themselves also significantly influence tetramer assembly. If the dissociation temperature of the secondary structures formed by the sequences is too high, once such stable secondary structures are formed, it is difficult to break this state, making tetramer assembly difficult. Therefore, it is necessary to control the dissociation temperature of the secondary structures corresponding to the four sequences assembling the tetramer to prevent it from becoming too high. For tetramers, it is necessary to control the dissociation temperature of the secondary structures of the four nucleic acid sequences. If a symmetrical structure is used ( Figure 1 In respectively with (Maintaining symmetry) Similar secondary structures will appear between pairs of sequences, and the dissociation temperatures of the two secondary structures are not much different. In this case, it is only necessary to control the secondary structure of the two nucleic acid sequences to achieve the previous effect. Therefore, symmetry is beneficial for controlling the secondary structure in tetramer optimization.
[0123] Table 4_1 Initialized and optimized tetramer sequences Table 4_3 Parameters of Tetramer Optimized Sequence Pairing Region Example 3: Design, synthesis and verification of pentamer nucleic acid backbone assembly The optimized tetramer sequence exhibits excellent assembly performance, largely because no pairing occurs at the center of the tetramer. In other words, the fixed core structure provides the tetramer with ample freedom, preventing the formation of complex complexes in the central region. Therefore, to integrate the tetramer sequence and fixed core structure in the optimization of the pentamer sequence, two schemes utilizing the tetramer sequence and fixed core structure from Example 2 were explored and designed.

The free energy of specific complementary pairing ( The non-specific pairing free energy is less than -27.4 kcal / mol.

[0125] This scheme uses a complete tetrameric fixed core structure, developing nucleic acid sequence W5 based on nucleic acid sequence formula 4, and nucleic acid sequence W6 based on nucleic acid sequence formula 4. W5 has the structure of formula 7, and W6 has the structure of formula 8. W3=X1-R1-X2-C1-X2-C2-Q1-X3 (5) W4=X1-Q1-C1-X2-C2-X2-R1-X3 (6) This scheme includes four structural sequences: Equation 1, Equation 4, Equation 5, and Equation 6.

[0127] A new solution is generated: random in , , and We select one sequence to update, thus obtaining a new nucleic acid sequence. We then test whether the dissociation temperature of this nucleic acid sequence is greater than 52℃, and simultaneously measure the free energy of the pairing region (…).

The constraints are then repeatedly updated if the dissociation temperature and the pairing region free energy are reached. The constraints of ) are applied according to the base pairing principle.

Becoming a new interpretation Because this scheme uses a complete fixed core structure and a portion of the tetramer sequence, the fixed core structure and the retained tetramer sequence portion must remain unchanged during the generation of new solutions.
[0128] Optimization judgment: Same as the optimization judgment in Example 1. The difference is that the initial annealing temperature decays to 0.9 of the current value.

[0135] Example 4: Conjugation of G-CSF to L-DNA The coupling of G-CSF and L-DNA employs a reductive amination reaction to selectively couple L-DNA with an aldehyde-modified 5' end to the N-terminus of G-CSF. The G-CSF buffer was replaced with acetate buffer (20 mM acetate, 150 mM NaCl, pH 5.0) using dilution or gel filtration chromatography, and the sample was concentrated to 30 mg / mL. 100 OD (1 OD = 33 µg) of aldehyde-modified L-DNA powder was dissolved in 60 µL of acetate buffer. 30 mg of sodium cyanoborohydride was dissolved in acetate buffer, adjusting the concentration to 800 mM. 50 µL, 60 µL, and 20 µL of the above concentrations of G-CSF, L-DNA, and sodium cyanoborohydride were mixed thoroughly and incubated at room temperature in the dark for 48 hours by rotation. The coupling effect was verified by polyacrylamide gel electrophoresis of samples before and after the reaction. The (L-DNA)-(G-CSF) conjugate showed a significant shift in the electrophoretic gel image compared to the uncoupled G-CSF, and the coupling efficiency reached 70%–80%. Figure 14 ).
[0136] Example 5: Purification of (L-DNA)-(G-CSF) conjugates The purification of (L-DNA)-(G-CSF) conjugates involves two steps. The first step uses Hitrap Q HP to remove unreacted G-CSF and the (L-DNA)2-(G-CSF) conjugate with two L-DNA strands linked to it. Figure 15 a). The reaction mixture obtained in Example 5 was diluted 10-fold with the loading buffer of the Q column and then loaded onto the column. Ten column volumes of loading buffer were used to elute the mixture to remove unreacted G-CSF. Then, 50 column volumes of elution were performed using a 0-100% linear gradient to separate the (L-DNA)-(G-CSF) conjugate and the (L-DNA)2-(G-CSF) conjugate. Polyacrylamide gel electrophoresis was used to identify the component type of each A280 absorption peak. Figure 15 (b) Collect the (L-DNA)-(G-CSF) conjugate (containing unreacted nucleic acids). In the second step, use Hiscrease CaptoMMC to remove the unreacted nucleic acids, finally obtaining a highly pure (L-DNA)-(G-CSF) conjugate. Figure 15 c). Load the samples collected in step one directly onto a Hiscrew Capto MMC column, elute with loading buffer for 10 column volumes to remove unreacted nucleic acids, and then elute the (L-DNA)-(G-CSF) conjugate with 100% elution buffer.
[0137] The purification conditions are shown in the table below: The purity of the (L-DNA)-(G-CSF) conjugate sample obtained by the two-step purification method was determined by 2% agarose gel electrophoresis. Figure 15 d) The gel image shows that there is only one nucleic acid band in the sample and the (L-DNA)-(G-CSF) conjugate is significantly shifted on the electrophoretic gel image compared to the unconjugated L-DNA, indicating that the unreacted nucleic acid and (L-DNA)2-(G-CSF) conjugate have been completely removed.
[0138] Example 6: Assembly of monovalent, divalent and trivalent G-CSF complexes The nucleic acid concentrations of S1-G-CSF, S3-G-CSF, S4-G-CSF, S2, S3, and S4 were determined using Nanodrop. Appropriate amounts of the above components were taken according to the structural design of monovalent, divalent, and trivalent protein complexes and mixed in a 1:1:1:1 molar ratio. After mixing, each assembly unit automatically assembled according to the base pairing principle. The assembly effect and sample purity were assessed by polyacrylamide gel electrophoresis before and after assembly. Figure 16 ).
[0139] Example 7: In vitro activity evaluation of G-CSF M-NFS-60 cells (mouse leukemia lymphocytes / G-CSF-dependent cells) were seeded in resuscitation medium (RPMI 1640 + 10% FBS + 15 ng / mL G-CSF + 1X penicillin-streptomycin) and resuscitated at 37°C with 5% CO2. Cells were passaged two to three times after reaching a confluence of 80%-90%, and then seeded into 96-well plates for plating. Corning 3599# 96-well plates were used for plating experiments, with a cell density of 6000 cells / well. Different samples (GCSF, NAPPA4-GCSF, NAPPA4-GCSF2, NAPPA4-GCSF3) were serially diluted to working concentrations of (0.001, 0.01, 0.1, 1, 10, 100 ng / mL) with a final volume of 100 μL. PBS was used as a control. After culturing in a constant temperature incubator for 48 hours, 10 μL of CCK8 solution was added to each well, and the culture plate was incubated in the incubator for 1-4 hours. The absorbance at 450 nm was measured using a microplate reader, and the cell proliferation rate of different samples was calculated.
[0140] Cell proliferation rate (%) = [A(drug-treated) - A(0-drug-treated)] / [A(0-drug-treated) - A(blank)] × 100 A (Drug Addition): Absorbance of the pores containing cells, CCK solution, and drug solution. A (Blank): Absorbance of wells containing culture medium and CCK8 solution but without cells. A (0 drug added): Absorbance of the well containing cells and CCK8 solution but no drug solution. The activity of a G-CSF-linked L-DNA tetramer framework was evaluated using the above activity assay methods. It was found that the L-DNA tetramer framework had no effect on the activity of G-CSF. Figure 17 Using the same activity assay, it was found that divalent and trivalent G-CSF assembled with L-DNA tetramers had no negative impact on the activity of G-CSF. Figure 18 ).
[0141] Example 8: Conjugation and purification of SM(PEG)2-PMO conjugates In this embodiment, morpholine phosphate (PMO) nucleic acids were used for the experiment. Specifically, the following four PMO single-stranded sequences (from 5' to 3') were selected. Chain 1 (PMO1): SEQ ID NO: 275 5'- AGCAGCCTCGTTGAATCGCCAAGACACC -3' Chain 2 (PMO2): SEQ ID NO: 276 5'- AGGTGTCTTGGCGAAAGTTGCTCCGACG -3' Chain 3 (PMO3): SEQ ID NO: 277 5'- ACGTCGGAGCAACTAAGCGGTTCTGTGG -3' Chain 4 (PMO4): SEQ ID NO: 278 5'-ACCACAGAACCGCTATCAACGAGGCTGC-3' The 5' end is modified with an NH2 group, which is used to couple the NHS active group of SM(PEG)2.
[0142] The PMO single chain containing 5'-terminal NH2 modification was dissolved in phosphate buffer (50 mM NaH2PO4, 150 mM NaCl, pH 7.4) to prepare a stock solution with a final concentration of 1 mM. SM(PEG)2 (linker molecule) powder was dissolved in dimethyl sulfoxide (DMSO) to prepare a fresh 250 mM SM(PEG)2 stock solution. 10–50 molar volumes of SM(PEG)2 stock solution were added to the PMO single chain stock solution, and the mixture was rapidly mixed and reacted at room temperature for 30 min–2 h. After the reaction was complete, 10% (v / v) of 1 M Tris-HCl (pH 7.0) was added to the reaction solution, and the mixture was incubated at room temperature for 20 min to terminate the reaction with excess SM(PEG)2. After incubation, SM(PEG)2-PMO was purified using HitrapCapto MMC. Unreacted SM(PEG)2 flowed directly through the column without binding. SM(PEG)2-PMO bound to the column was eluted with buffer (25 mM BICINE, 200 mM NH4Cl, 1 M Arginine monohydrochloride, pH 8.5). The elution results are as follows. Figure 19 As shown in a.
[0143] PMO samples before and after coupling were analyzed using positive ion mode liquid chromatography-mass spectrometry. For example... Figure 20 a and Figure 20 As shown in b, the results indicate that the molecular weight of the finally obtained SM(PEG)2-PMO is consistent with the theoretical value, and the coupling reaction efficiency is high.
[0144] Example 9: Preparation of Nanobody Mutants A cysteine mutation was introduced at the carboxyl terminus of the nanobody for nucleic acid conjugation. The gene sequence of the anti-HSA nanobody was optimized to use yeast-preferred codons and then subcloned into the pPICZ alpha A plasmid. The amino acid sequence of the anti-HSA nanobody is SEQ ID NO: 279. A His tag was added to the N-terminus of the nanobody to facilitate purification.
[0145] SEQ ID NO: 279, Amino acid sequence of anti-HSA nanobody mutant: HHHHHHAVQLVESGGGLVQPGNSLRLSCAASGFTFRSFGMSWVRQAPGKEPEWVSSISGSGSDTLYADSVKGRFTISRDNAKTTLYLQMNSLKPEDTAVYYCTIGGSLSRSSQGTQVTVSSGSC After linearization, the plasmid was electroporated into Pichia pastoris strain X33, and strains with high copies of the target gene were selected using Zeocin concentration gradient YPD agar plates. Single clones were cultured in GMGY at 30℃ and 250 rpm to obtain sufficient cells. Then, the target nanobody was induced to be secreted and expressed by GMMY at 20℃ and 250 rpm, with 1% methanol added every 24 hours.
[0146] High-copy-selected strains can achieve nanobody expression yields of 40-80 mg / L in laboratory-grade glass flasks.
[0147] SDS-PAGE analysis revealed that the culture supernatant contained a large amount of target nanobody monomers and nanobody dimers after 72 hours of induction. The nanobodies in the culture supernatant were purified using a His-tagged affinity column.
[0148] Example 10: Conjugation and purification of nanobody-PMO conjugates The His-tagged affinity chromatography-eluted nanobody sample (Example 9) was dialyzed using a dialysis buffer containing a reducing agent (20 mM Tris, 15 mM NaCl, pH 7.4). During dialysis, the C-terminal thiol groups were reduced, and small impurity molecules such as free -SH groups were removed. The reduced nanobody was mixed with SM(PEG)2-PMO single chain (prepared in Example 8) at a molar ratio of 1:1 to 2, and reacted at room temperature for 2 hours after thorough mixing.
[0149] Identification via SDS-PAGE, such as Figure 19 The results from b show that the coupling efficiency can reach over 90%.
[0150] Unreacted SM(PEG)2-PMO single chains were removed using a His-tagged affinity column, and nanobodies and nanobodies-PMO mixtures were collected.
[0151] Using Superdex TM 75 Increase 10 / 300 GL to separate nanobodies and nanobodies-PMOs, such as Figure 21 As shown, nanobodies and nanobodies-PMOs were effectively separated.
[0152] Analysis of nanobodies before and after nucleic acid conjugation using positive ion mode liquid chromatography-mass spectrometry, such as Figure 20 Results c and d show that the molecular weight of the finally obtained nanobody-PMO is consistent with the theoretical value.
[0153] Example 11: NAPPA-PMO drug self-assembly The self-assembly process of NAPPA-PMO drugs is introduced below using pmo-NAPPA4-HSA(1) as an example.
[0154] The concentrations of anti-HSA Nb-PMO1, PMO2, PMO3, and PMO4 were determined respectively. Appropriate amounts of the above components were preheated at 37°C for 5 min, then mixed at a 1:1 molar ratio at 37°C and incubated for 1 min. This completed the assembly of pmo-NAPPA4-HSA(1).
[0155] The assembly of pmo-NAPPA4-HSA(1,2,3) is similar, and the required assembly modules are anti-HSA Nb-PMO1, anti-HSA Nb-PMO2, anti-HSA Nb-PMO3 and PMO4.
[0156] Under low-temperature conditions, SDS-PAGE was used to identify the assembly of the samples, such as... Figure 22 The results showed that the assembled sample bands were uniform.
[0157] Example 12: Verification of the binding activity of nanobody-PMO monomer and assembled NAPPA-PMO drug The following uses pmo-NAPPA4-HSA(1) as an example to detect the binding ability of Anti-HSA nanobody, Anti-HSA Nb-PMO1 monomer and assembled pmo-NAPPA4-HSA(1) to HSA protein (Bipsys, HSA-H5220) using ELISA.
[0158] 100 ng of HSA protein was coated into each well of a 96-well microplate and incubated overnight at 4°C. After washing with washing buffer (PBS containing 0.05% Tween-20) and blocking with blocking buffer (PBS containing 3% BSA and 0.05% Tween-20), serially diluted Anti-HSA nanobody, PMO-conjugated Anti-HSA Nb-PMO1 nanobody, and assembled pmo-NAPPA4-HSA(1) were added and incubated at room temperature for 1 hour. After washing three times, horseradish peroxidase-conjugated rabbit anti-camel VHH antibody (GenScript, A02016) diluted 1:5000 was added and incubated at room temperature for 1 hour. After washing three times, tetramethylbenzidine substrate solution (Beyotime, P0209) was added for color development. The color development was stopped using stop solution (Beyotime, P0215). The absorbance at 450 nm of each well was read using a microplate reader (Molecular Devices, SpectraMax i3x) and the corresponding EC50 was calculated.
[0159] like Figure 23 The calculation results show that the EC50 values of Anti-HSA nanobody, Anti-HSA Nb-PMO1 and assembled pmo-NAPPA4-HSA(1) bound to HSA protein are 0.577 nM, 0.391 nM and 0.529 nM, respectively. This indicates that the PMO conjugation method does not affect the binding activity of nanobody to corresponding antigen, and the PMO assembly method also does not affect the binding activity of nanobody to corresponding antigen.
[0160] Example 13: Nuclease Degradation Resistance Experiment of NAPPA-PMO Drug To verify whether PMO, as a nucleic acid derivative, can withstand degradation by various nucleases, and to validate whether the assembled NAPPA-PMO drug is also resistant to nucleases or depolymerization, the following experiment was designed. Three common nucleases, DNase I (Thermo Scientific, EN0523), T7 Endonuclease I (NEB, M0302S), and S1 Nuclease (Thermo Scientific, EN0321), were used to incubate the PMO assembled sample pmo-NAPPA4-HSA(1) and the D-DNA assembled sample DDNA-NAPPA4 (control) at 37 degrees Celsius for 1 hour. The incubated pmo-NAPPA4-HSA(1) and DDNA-NAPPA4 were analyzed by SDS-PAGE and 2% agarose gel electrophoresis, respectively.
[0161] like Figure 24As shown, pmo-NAPPA4-HSA(1) is not degraded by the three nucleases (left figure), while DDNA-NAPPA4 is completely degraded by DNase I and S1 Nuclease and cleaved into shorter fragments by T7 Endonuclease I. Therefore, the experiment shows that the NAPPA-PMO drug can withstand common nuclease degradation.
