Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an effective ingredient delivery system for prolonging in vivo half life of an active ingredient,

In this specification, contents concerning an active ingredient delivery system for extending the in vivo half-life of an active ingredient are described.

The time for which the efficacy of the active ingredients administered in vivo is maintained in the body is very important. The longer the holding time, the lower the dosage and the number of administration. One of the ways to increase the in vivo efficacy maintenance time of the active ingredients may be to control the time that the active ingredient remains in the body, i.e., the half-life.

In recent years, bio-derived molecules have been widely used for the diagnosis and treatment of diseases, and representative examples are peptides-based proteins classified into antibodies, various hormones and enzymes according to their functions.

In order for such a biologically active protein to be effectively used as a therapeutic drug, it is very important to control the time, i.e., half-life, of staying in the body when administered to the body. In particular, the limitations of the potential therapeutic effects of these proteins quickly disappear in the body. As a result, there is a problem that the number of injections increases in order for the therapeutic drug to maintain a stable level in the body. Therefore, one of the most important factors for the development of a successful protein drug is the development of a method to prolong the half-life of the drug. When the half-life is increased, there is a great advantage that the level of drug exposure can be reduced and the time spent in the body can be increased to ultimately reduce the amount of drug administered.

Telomere is a genetic material that is repeatedly present at the end of a chromosome, and is known to prevent damage to the chromosome or its binding to other chromosomes. As the cell divides, the length of the telomere is getting shorter. When there is more than a certain number of cell divisions, the telomere becomes very short, and the cell stops dividing and dies. On the other hand, it is known that lengthening the telomeres prolongs the life of the cells. For example, it is known that the cancer cells secrete an enzyme called telomerase and prevent the shortening of the telomeres.

Serum albumin is the most abundant protein in blood and plays an important role as a delivery medium for fatty acids and drugs (cf. Advanced Protein Chemistry, 37, 161-245, 1985). The albumin synthesized in the liver not only can increase the half-life of the body through interaction with the FcRn receptor, a major histocompatibility (MHC class I) molecule (see Protein Engineering, Design & Selection 23 : 11, 827-834, 2010) and are known to help maintain homeostasis (cf. The Lancet, December 16, 1989). Therefore, the peptide binding to the albumin becomes capable of increasing the blood half-life of the active ingredient bound to the peptide.

In one aspect of the invention, the amino acid change is of a property that causes the physicochemical properties of the peptide to change. For example, amino acid changes such as improving the thermal stability of the peptide, altering the substrate specificity, changing the optimum pH, etc. can be performed.

As used herein, the term "amino acid" includes D-isomers and modified amino acids as well as the 22 standard amino acids that are naturally incorporated into the peptide. Accordingly, in one aspect of the present invention, the peptide may be a peptide comprising a D-amino acid. In another aspect of the present invention, the peptide may include post-translationally modified non-standard amino acids and the like. Examples of post-translational modifications include phosphorylation, glycosylation, acylation (including, for example, acetylation, myristoylation and palmitoylation), alkylation ), Carboxylation, hydroxylation, glycation, biotinylation, ubiquitinylation, changes in chemical properties (such as, for example, beta-depleted deamidation , Deamidation) and structural changes (e.g., formation of a disulfide bridge). Also included are amino acid changes such as changes in amino acids, such as changes in amino groups, carboxy groups or side chains, caused by chemical reactions that take place during binding with crosslinkers to form peptide conjugates.

The peptides disclosed herein may be wild type peptides identified and isolated from natural sources. Alternatively, the peptides disclosed herein may be artificial variants, including amino acid sequences in which one or more amino acids are substituted, deleted and / or inserted, as compared to peptides that are fragments of SEQ ID NO: 1. Amino acid changes in wild-type polypeptides as well as in artificial variants include conservative amino acid substitutions that do not significantly affect folding and / or activity of the protein. Examples of conservative substitutions include, but are not limited to, basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine, valine and methionine) Tryptophan and tyrosine), and small amino acids (glycine, alanine, serine and threonine). In general, amino acid substitutions that do not alter specific activity are known in the art. The most commonly occurring interactions are Ala / Ser, Val / Ile, Asp / Glu, Thr / Ser, Ala / Gly, Ala / Thr, Ser / Asn, Ala / Val, Ser / Gly, Tyr / Lys / Arg, Asp / Asn, Leu / Ile, Leu / Val, Ala / Glu, and Asp / Gly, and vice versa. Other examples of conservative substitutions are shown in the following table.

Substantial variations in the biological properties of the peptide include (a) the structure of the polypeptide backbone within the substitution region, e.g., their effect in maintaining the sheet or helical conformation, (b) the charge of the molecule at the target site Or their effect in maintaining hydrophobicity, or (c) their effect in maintaining the bulk of the side chain is significantly different. The natural residues are grouped into the following groups based on their usual side chain properties:

(1) hydrophobicity: norleucine, met, ala, val, leu, ile;

(2) Neutral hydrophilic: cys, ser, thr;

(3) Acid: asp, glu;

(4) Basicity: asn, gln, his, lys, arg;

(5) Residues affecting chain orientation: gly, pro; And

(6) Aromatic: trp, tyr, phe.

Non-conservative substitutions will be made by exchanging one member of these members for another. Any cysteine residue not associated with maintaining the proper stereostructure of the peptide can generally be replaced with a serine to enhance the oxidative stability of the molecule and prevent strange cross-linking. Conversely, cysteine bond (s) can be added to the peptide to improve its stability

Other types of amino acid variants of peptides are those in which the glycosylation pattern of the antibody is altered. The term change refers to the deletion of one or more carbohydrate moieties found in the peptide and / or the addition of one or more glycosylation sites that are not present in the peptide.

Glycosylation of peptides is typically N-linked or O-linked. N-linked refers to a carbohydrate moiety attached to the side chain of an asparagine moiety. The tripeptide sequences asparagine-X-serine and asparagine-X-threonine (where X is any amino acid except proline) are recognition sequences for enzymatically attaching carbohydrate moieties to asparagine side chains. Thus, the presence of one of these tripeptide sequences in the polypeptide creates a potential glycosylation site. O-linked glycosylation refers to attaching one of the sugars N-acetylgalactosamine, galactose or xylose to a hydroxyamino acid, most commonly serine or threonine, but 5-hydroxyproline or 5-hydroxylysine May be used.

Addition of the glycosylation site to the peptide is conveniently accomplished by varying the amino acid sequence to contain one or more of the above-mentioned tripeptide sequences (in the case of N-linked glycosylation sites). Such changes may be made by adding one or more serine or threonine residues to the sequence of the original antibody or by substituting these residues (for O-linked glycosylation sites).

Example 5: Preparation of carrier peptide-GFP conjugate

Conjugates of carrier peptides and Green Fluorescent Protein (GFP) (SEQ ID NO: 3, SEQ ID NO: 4) were prepared by the following method. Specifically, for example, a gene encoding the pep1 peptide (16mer) of SEQ ID NO: 1 was cloned into the pET28a (+) vector expressing GFP to induce overexpression of the pep1 peptide (16mer) Expressed in E. coli BL21 and purified.

First, as shown in FIG. 1, a primer was prepared for cloning Green Fluorescent Protein (GFP) into pET28a (+) vector (Promega). The primer contained an EcoRI cleavage site at the 5 'end and a HindIII cleavage site at the 3' end. The EcoRI site contained about 21 bp of the GFP prefix sequence and a Hind codon at the HindIII site. For the production of the GFP-carrying peptide protein gene, the 5 'side was identical to GFP but was prepared so as to include a sequence encoding a carrier peptide in front of GFP. For example, in the case of SEQ ID NO: 1 (Pep 1) peptide, it was made to include the following sequence: GAA GCG CGC CCG GCG CTG ACC AGC CGC CTG CGC TTT ATT CCG AAA (SEQ ID NO: 5). As a comparative example, "TAT GGT CGT AAA AAA CGT CGT CAA CGT CGT CGT" was prefixed to GFP to prepare TAT-GFP.

The forward primer was prepared by adding 21 GFP sequences to the pET-28a-GFP vector using the above primers and the forward primer followed by the carrier peptide coding sequence. The reverse primer was a C-terminal sequence part of GFP And PCR was carried out. PCR was carried out at 95 ° C for 5 minutes and 30 cycles at 95 ° C for 5 minutes (denaturation), 63 ° C for 30 seconds (annealing), 72 ° C for 1 minute (elongation) and 72 ° C for 7 minutes. Each primer was used at 10 pmol. Using these PCR conditions, GFP and GFP-carrying peptide DNA fragments were amplified and cloned into the EcoRI and HindIII sites of pET28a (+) vector to obtain a vector expressing GFP and GFP-carrying peptide ).

The vector was then transformed into bacteria to isolate the protein. Specifically, E. coli BL21 (DE3) (Invitrogen, Carlsbad, Calif., USA) was transformed with each of the above vectors, cultured in 5 ml LB / kanamycin medium and transferred to 100 ml medium. In this case, kanamycin was added in 1/1000 volume ratio. After incubation at 37 ° C for about 2-3 hours with stirring, the absorbance was measured to about 0.6-0.8, followed by 1 mM IPTG (Isopropyl β-D-1-thiogalactopyranoside). After further culturing for 3-4 hours, the cells were centrifuged at 5000 rpm for 5 minutes.

As a result of the centrifugation, the expressed protein can be visually confirmed that the cell is over-expressed when it becomes green light. The protein separation kit (Prod, # 21277, Thermo Scientific, IL, USA), a His tag purification kit, was isolated according to the manufacturer's instructions.

After separation, the protein was purified by dialysis and concentrated. Specifically, dialyzed with sterilized PBS at 4 ° C. First, the dialysis bag was equilibrated in advance with PBS, and the protein solution separated from the above was taken in a 5 ml syringe and put in a dialysis bag, and dialyzed overnight at 4 ° C. with stirring. Subsequently, the protein dialyzed on BIBASPIN 20 (Prod, # VS2092, Sartorius Stedin biotech, Germany) was added to increase the concentration of the protein and to remove unnecessary substances, followed by concentration by centrifugation at 3,000 rpm at 4 ° C.

As a result, a band of about 65 kDa was confirmed (FIG. 3). The protein bands specifically binding to the 16-mer were cut and subjected to a proteomic analysis (Maldi-TOF) to a specialized analysis institution. Furthermore, human serum was immunoprecipitated by the same method using biotin-labeled 16-mer peptides. As a result, 16-mer peptides were found to bind to albumin (65 kDa) more than the control group ).

Each of the concrete steps will be described in more detail below.

Mycobacteria intracellulare was lysed in 7H9 medium containing 10% ADC (albumin dextrose and catalase, Prod. # 272352, Becton, Dickinson and Company, MD, USA). Lysing conditions are as follows. The process of stopping 0.7 seconds after 0.3 second pulse was repeated 3 times for 5 minutes to perform sonication. The sonicated sample was then centrifuged at 10,000 rpm for 15 minutes to separate the supernatant.

1 ml of HEK 293 cells (approximately 1 × 10 6) was collected and centrifuged at 1300 rpm for 5 minutes to obtain a precipitate. One ml of a lysis buffer (Prod. # 87787, Thermo Scientific, UL, USA) and a protease ingibitor complex, # 05892791001, IN, USA) were added, vortexed, and placed in ice for 30 minutes. After centrifugation at 13,000 rpm for 10 minutes in a 4 ° C centrifuge, the supernatant was taken.

6xHis-labeled cobalt resin was prepared (Prod. # 89964, Thermo Scientific, UL, USA) to attach the purified GFP-expressing protein to the resin in Example 5. 50-100 μl of resin was added to the column, and washed with 500 μl each 5 times in a washing buffer. Each of the expressed proteins purified in Example 5 was added thereto, and allowed to mix for 30 minutes to 1 hour while being rotated at 4 캜. After that, 500 μl of the expressed protein-resin polymer was washed 5 times in the washing buffer. Then, the above prepared cell lysate is added, and the mixture is allowed to stand overnight while being rotated at 4 ° C overnight. The next day, the resin was washed with a washing buffer in the same manner and 200 μl of an elution buffer was added to elute the resin. As a control, GFP Control expression protein (WT-GFP), another 11-mer expression protein (11-GFP) and ccg-GFP were tested in the same manner as above. 11mer-GFP is an 11-mer protein of 11 aa derived from HBV conjugated with GFP. ccg is the replication origin of Hepatitis B virus.

(2) Protein electrophoresis and specific binding protein analysis using SDS-PAGE

A 5X SDS sample buffer was added to 20-40 용 of the eluted protein prepared in the above (1), boiled, and centrifuged at 13,000 rpm for 1 minute. The supernatant was then loaded onto a 12% SDS-PAGE protein electrophoresis gel and electrophoresed at 100 volts for 2 hours 30 minutes. After electrophoresis, the gel was placed in distilled water for 20 minutes, and stained with a silver staining kit (PROT-S1L1, Sigma-Aldrich, St. Louis, USA). The results are shown in Fig. A dyed band of about 65 kDa (FIG. 3) was cut and subjected to analysis by a proteome analysis institution (Yonsei University Proteome Research Institute, Seoul, Korea). As a result, the protein was identified as serum albumin. From this, it can be seen that the present 16mer polypeptide binds to serum albumin.

(3) Identification of albumin binding using human serum

Blood from a healthy donor was mixed in a volume ratio of 4: 1 with phycol and centrifuged at 400 g for 30 minutes to separate the serum. Subsequently, immunoprecipitation was carried out in the same manner as in the above (1), followed by SDS-PAGE analysis. The result is shown in Fig. As a result, it was confirmed that pep1-GFP conjugate (16-mer peptide) binds more to 65kDa albumin than the control group.

Example 7: Toxicity test

(1) Preparation of cells

HeLa cell lines obtained from ATCC were cultured in MEM (Minimum Essential Medium) supplemented with 10% fetal bovine serum (Invitrogen, USA) and Earle's salts, non-essential amino acids, sodium pyruvate and 100 μg / ml penicillin and streptomycin ) Was added, and the cells were cultured in a 5% CO 2 incubator at 37 ° C.

(2) Cell survival rate and toxicity analysis

In the meantime, the cultured cell line was divided into 96-well plates, and 10% fetal bovine serum (Invitrogen, USA), 100 μg / ml penicillin and 100 units / ml streptomycin were added to the medium. For 12 hours. After washing with PBS, the cells were starvated in MEM (Minimum Essential Medium) for 1 hour. After 20 uM of each pep1 was cultured at 37 ° C for 24 hours, cell viability and toxicity were analyzed by MTT assay. The results are shown in Fig.
