Description

[0001] The present invention relates to a pharmaceutical composition for accelerating bone regeneration comprising asialic acid or a pharmaceutically acceptable salt thereof as an active ingredient,

The present invention relates to a pharmaceutical composition for regenerating a bone defect such as a bone tissue, a fracture or a bone defect destroyed by periodontal disease containing asiatic acid or a pharmaceutically acceptable salt thereof as an active ingredient.

Reconstructive surgery through bone regeneration has been extensively carried out in orthopedics and plastic surgeons as well as in dentistry to restore the inherent and acquired damaged bone structure. Currently, the materials used for bone regeneration are classified into three categories according to the osteogenesis ability: osteogenesis, osteoconduction, and osteoinduction.

The bone-forming material is a self-made bone that can make bone by itself by preparing cells and growth enzymes necessary for bone regeneration by themselves. In contrast, the bone conduction material is absorbed after serving as a scaffold necessary for bone regeneration, and includes various allografts, heterogeneous bone, and xenografts. Finally, bone-derived material is a material capable of differentiating mesenchymal cells into bone cells to produce bone.

In the early days, the bone-inducing substance was limited to the Demineralized Bone Matrix (DBM). However, recently, various growth factors have been studied and applied so that not only bone differentiation but also vascularization and macrophage function involved in bone healing It is reaching to the regulating ground. In 2001, Clokie and Sandor et al. Described "osteoactive agents" for the Bone Morphogenetic Protein (BMP), Platelet Rich Protein (PRP), and Plasma Rich in Growth Factor (PRGR) I have defined it.

In the regenerative procedure applied to the periodontal region, various bone grafts are used to form neonatal cementum, periodontal ligament fibers and new bone in the lost periodontal tissue and to achieve renal adhesion. To date, autogenous bone grafting has shown the greatest amount of bone regeneration, but there is a limitation in the amount of additional surgery and acquisition of the donor site, and complications such as osseointegration and root resorption may occur. Therefore, there is a great increase in interest and application of a bone inducing substance having a superior bone forming ability and less restriction of a donating part.

Recently, BMP, which has been under much interest and studied, was first introduced by Urist in 1965 as a member of the Transforming Growth Factor (TGF-β) superfamily, and was first isolated in the DBM of rabbits and cows in 1980. Since the recombinant Human Bone Morphogenetic Protein (rhBMP) has been synthesized, known BMPs have been found in about 20 species. They are 30 ~ 38 kDa homodimers, synthesized in prepropetides composed of 400 ~ 525 amino acids, . It is known to induce cartilage and bone formation and to provide a basic environment for functional bone marrow formation during bone formation. In particular, BMP-2 is able to develop directly neuronal cells, and has the ability to induce chondroblasts and osteoblasts, differentiates the surrounding immature mesenchymal cells into osteogenic cells, and stimulates and regulates osteogenesis .

BMP has recently been approved by the US FDA and has been commercialized, and various attempts have been made to make it easier to apply to clinical practice, but so far it has been supplied in liquid form. Therefore, when the BMP alone is applied, not only the operability is poor but also it is difficult to induce bone formation because it spreads to the implantation site and is quickly absorbed.

Asiatic acid is a natural organic compound isolated from Centella asiatica . It has been developed as a skin cream and has been already proven in human body. It has been reported that it has anti-inflammatory function. J Agric Food Chem, 1, 63 (12): 12-24. [CrossRef], [Web of Science ®] View all references).

< Example  1> Origin of human alveolar bone marrow Intermediate lobe  Human alveolar bone marrow mesenchymal  stem cells; hAD - BMSC ) &Lt; / RTI &gt; Osteoblast  Induction of differentiation

To obtain human alveolar bone marrow-derived mesenchymal stem cells (hAD-BMSC), alveolar bone marrow aspirates (0.5-1.0 cc) were injected into an osteotomy site during dental implant surgery using an 18-gauge needle syringe (Four patients aged 50 to 60 years). All patients were approved by the Clinical Research Ethics Committee at Wonkwang University School of Dentistry. hAD-BMSC was isolated and proliferated according to the method reported previously (Matsubara T, SK, Ishii M, Sugiyama M, Igarashi A, Oda R, Nishimura M, Saito M, Nakagawa K, Yamanaka K, Miyazaki K, Shimizu M , Bhawal UK, Tsuji K, Nakamura K, Kato Y., Alveolar bone marrow as a cell source for regenerative medicine: differences between alveolar and iliac bone marrow stromal cells. J Bone Miner Res, 2005. 20 (3): 399-409 .). The characteristics of the hAD-BMSC such as the morphology, surface markers and the ability to differentiate into osteoblasts have already been known, and the present inventors used 3-6 lineage cells. Specifically, in order to induce osteoblast differentiation, cells (about 90% confluence) were supplemented with 10 mM? -Glycerophosphate, 50 占 퐂 / mL ascorbic acid and 100 mM dexamethasone ) (Sigma Aldrich, St. Louis, Mo., USA). The culture medium and OS were also replaced every 2 days after the initial plating.

< Example  2> Statistical analysis

The experimental results are shown as mean ± mean error. Multiple comparisons were made using one-way analysis variance (ANOVA) followed by Dunnett's test. P values <0.05 and <0.01 were considered statistically significant.

< Experimental Example  1> Asiatic acid  Confirming cell proliferation inducing effect

To confirm the effect of asiatic acid (Sigma Aldrich) on inducing proliferation of hAD-BMSC into osteoblasts, MTT assay was performed.

Specifically, hAD-BMSC was cultured in a 96-well culture medium at a concentration of 5 × 10 3 / well, cultured with an asialic acid treatment, and cultured for 1, 2, 3, 4 and 5 days And 20 μl of the MTT solution prepared at a concentration of 5 mg / ml was added to the cell culture medium to measure the absorbance. Then, light was blocked with foil, and the mixture was incubated for 4 hours at 37 ° C in a CO 2 incubator. After removing the culture solution, 200 μl of DMSO was added and dissolved, and the absorbance was measured at 590 nm.

As a result, as shown in Fig. 1, asiatic acid (1 and 10 占 퐂 / mL) was cultured more than the OS treated group of Example 1, which was a negative control and a positive control, (Fig. 1). As shown in Fig.

< Experimental Example  2> Asian acid hAD - BMSC Confirming the effect of promoting bone differentiation

<2-1> Asian acid APL (Alkaline 포스화제 ) And activity of calcium accumulation

In order to measure the differentiation effect of asialic acid from hAD-BMSC to osteoblast, activity and staining of intracellular ALP, known as an indicator enzyme of bone cell activity, were performed.

Specifically, ALP activity was measured by a conventionally reported method using p-nitrophenyl phosphate as a substrate 5 days after the OS treatment in Example 1 above. In addition, the asialic acid of the present invention (1 and 10 占 퐂 / mL) was also treated at the time of OS treatment. ALP activity was normalized to total protein content as measured by BCA protein assay (Pierce, Rockford, USA). The results were expressed as nmol / 30 min / mg (protein) and the experiment was repeated 4 times. In order to investigate ALP activity through histochemical analysis, cells were incubated with 0.1 mg / mL naphthol AS-MX phosphate (Sigma Aldrich) and 0.6 mg / mL fasteless Violet Elbitate (Sigma Aldrich) Fast Red Violet LB Salt) (Sigma Aldrich) and photographed with a digital camera (Nikon D80).

Calcium accumulation was also measured using Alizarin Red sulfate (AR-S) (Sigma Aldrich).

Specifically, hAD-BMSCs were continuously cultured in 24-well plates for 21 days with treatment with asialic acid (1 and 10 / / mL). Cells were then fixed with ice-cold 70% ethanol for 1 hour at 4 ° C, and ethanol was removed. Cells were then stained with 40 mM AR-S staining solution for 1 minute at room temperature. The stained cells were photographed with a digital camera (Nikon D80).

As a result, as shown in FIG. 2 and FIG. 3, the OS-treated cells showed strong ALP staining and showed strong ALP staining even in the cells treated with the asialic acid (1 and 10 / / mL) Respectively. In addition, it was confirmed that the ALP activity was significantly increased in the OS and the asialic acid (1 and 10 ㎍ / mL) -treated group compared to the non-treated control group (Fig. 2B). It was also found that the calcium accumulation was increased in the AR-S staining group treated with asialic acid (1 and 10 / / mL) as compared to the untreated control group (Fig. 3).

After incubation of hAD-BMSC cells for 5 days in the presence or absence of OS and asiatic acid, the cells were incubated for 5 days with coli alpha (Collagen type I alpha), ALP, OCN (osteocalcin) and BSP (bone sialoprotein) The effect was confirmed.

Specifically, the asialic acid and the OS-treated hAD-BMSC were collected and homogenized in Trizol reagent, and then the organic layer and the aqueous solution layer were separated using chloroform. RNA was then recovered via isopropyl alcohol precipitation. The pellet was washed with ice-cold 70% ethanol and RNA concentration was calculated with Nano-drop 2000. Semi-quantitative PCR (RT-PCR) was performed using HiPi one-step 5 × RT-PCR Premix (ELPIS, Korea) with GAPDH as a control. A primer set for each gene was designed and the annealing temperature for semi-quantitative PCR was determined. After amplification, the PCR products were separated by electrophoresis on a 1% (w / v) agarose gel stained with 0.5 μL / mL EtBr and images were obtained with a gel imaging system (red TM, Alpha Innotech, , And JPG file format. Then, the signal intensity of the captured image was quantified using Image J software (http://rsbweb.nih.gov/ij/). Relative density was determined by the signal intensities of ColI, ALP, OCN and BSP for GAPDH, and GAPDH was used to standardize the variation of all RNA amplification efficiencies. The primers used for the amplification are shown in Table 1 below.

As a result, as shown in Fig. 4, it was confirmed that the asialic acid of the present invention increased expression of ColI alpha, ALP, OCN and BSP, which are known as osteoblast differentiation markers (Fig. 4).

Therefore, it was confirmed that the asialic acid of the present invention promotes the bone differentiation ability of hAD-BMSC by increasing ALP activity and calcium accumulation and increasing expression of ColI alpha, ALP, OCN and BSP, which are known as osteoblast differentiation markers.

<Experiment 3> In the rabbit skull defect model Asian acid  Check bone formation effect

A total of two bone defects were formed in the skull of New Zealand white rabbits (n = 3) using a 5 mm diameter trephine burr. Group 1 was treated with a bone graft material deproteinized bovine bone (0CS-B) alone, and Group 2 was treated with 200 μl of 40 ug / ml asialic acid in 0CS-B and then sutured. After sacrifice 4 weeks after the experiment, tissue sections were formed to a thickness of 4-μm, and histological analysis was performed through an optical microscope.

As a result, as shown in Fig. 5, a dense connective tissue was formed in a group of only bone graft materials (Fig. 5A), and new bone was formed to some extent around the bone graft material (Fig. 5A) The use of asianic acid with bone graft material resulted in more bone regeneration than that of bone graft material alone. Large amount of bone graft was formed along the surface of bone graft material, and new bone around bone graft material was in close contact with the graft material (Fig. 5 (b)). In addition, Osteoblastic lining cells appeared not only around the bone graft material but also around the new bone, and it was confirmed that the bone marrow regeneration activity was significantly higher in the group using the Asian acid with the bone graft material (Fig. 5).
