Abstract
Description
Technical Field
[0001] This invention relates to an anti-inflammatory composition comprising N-benzyl-N-methyldecane-1-amine or a derivative thereof as an active ingredient. Background Technology
[0002] Inflammation refers to the pathological state of abscess formation caused by the invasion of external bacteria. The inflammatory response is a biological defense process used to repair and regenerate damage caused by the invasion of bacteria that cause certain organic changes in living cells or tissues. When tissues (cells) are damaged or infected by external infectious agents (bacteria, fungi, viruses, various allergens), various inflammatory mediators and immune cells in local blood vessels and body fluids participate in the process, showing a series of complex physiological reactions such as enzyme activation, secretion of inflammatory mediators, invasion of body fluids, cell migration, and tissue destruction, as well as external symptoms such as erythema, edema, fever, and pain.
[0003] Under normal circumstances, the inflammatory response clears external sources of infection, regenerates damaged tissues, and restores bodily functions. However, if antigens are not cleared or if the inflammatory response is excessive or persistent due to internal substances, it can become the main pathological phenomenon of the disease (allergic diseases, chronic inflammation) and can also become an obstacle in the treatment process such as blood transfusion, drug administration, and organ transplantation.
[0004] To alleviate these inflammatory symptoms, nonsteroidal anti-inflammatory drugs such as ibuprofen and indomethacin are used, while steroidal drugs such as dexamethasone are used, but their use is limited due to reported side effects related to stability.
[0005] Therefore, there is a need to develop a safe anti-inflammatory substance with maximum efficacy and minimal side effects. Summary of the Invention

[0062] Figure 10 and Figure 11 It is further support Figure 9 A and Figure 9 Detailed results for B. Detailed Implementation
[0063] The various embodiments and experimental examples of the present invention will now be described in detail. However, the following embodiments are merely some examples of the present invention, and the present invention should not be construed as being limited to these embodiments.
[0064] <Example 1: Confirmation of the structure and synthesis of BMDA (FMJ-G0) and its derivative (FMJ-G4)>
[0065] 1 M N-benzylmethylamine and decanal were mixed in methanol and stirred for 20 minutes. Then, sodium triacetoxyborohydride [NaBH(OAc)3] was added and the mixture was stirred for another hour. Under vacuum, the volatile organic solvent was removed, and impure BMDA (benzyl-decyl-methyl-amine) was extracted with ethyl acetate saturated with sodium bicarbonate. Further purification of BMDA was obtained by column chromatography, followed by H₂ chromatography. 3 -NMR confirmed its structure (see Figure 1A The chemical structure of the synthesized substance is represented by the following formula 1-1.
[0066] [Chemical Formula 1-1]
[0067]
[0068] Additionally, in the same manner, FMJ-G4 (DMMA, Decyl-(4-methoxy-benzyl)-methyl-amine) was synthesized starting from 1-(4-methoxyphenyl)-N-methylmethanamine and decanal, and this structure was also obtained via H... 3 - NMR confirmed (see Figure 1B The chemical structure of the synthesized substance is represented by the following formula 1-2.
[0069] [Chemical Formula 1-2]
[0070]
[0071] <Example 2: Evaluation of the anti-inflammatory efficacy of BMDA (FMJ-G0) and its derivatives (DMMA, FMJ-G4)>
[0072] 1. To evaluate the inhibitory effects of lipopolysaccharide (LPS) induced by BMDA (FMJ-GO) and its derivative (DMMA) on inflammation-related signaling activity and its inhibitory effects on TNF-α and IL-β inflammatory cytokines.
[0073] Human THP-1 mononuclear cell lines (5 × 10^5 cells / well) were cultured in 6-well plates with BMDA (FMJ-GO) and DMMA (FMJ-G4) at concentrations of 4 μM, 2 μM, and 1 μM for 3 hours. Each well was then treated with lipopolysaccharide at a concentration of 1 mg / ml. After 1 hour, the cells were centrifuged, and the supernatant was used to evaluate inflammatory cytokines by ELISA. The recovered THP-1 cells were then placed in cell lysis buffer for Western blotting.
[0074] In addition, under the same conditions, mononuclear THP-1 cell lines treated with lipopolysaccharide (LPS) and BMDA / DMMA were divided into cytoplasmic and nuclear portions, and the distribution of NF-κBP65 protein in the cytoplasm and nucleus was examined by immunoblotting.
[0075] See results Figure 2A and 2B, BMDA (FMJ-G0) and its derivative DMMA (FMJ-G4), low molecular weight compounds inhibited LPS-activated p38 MAPK and JNK activity. Furthermore, they also inhibited inflammation-related signaling pathways linked to p38 MAPK-MK2. These results confirmed that these low molecular weight compounds exhibit concentration-dependent activity.
[0076] On the one hand, the biological significance of this result lies in the fact that, through ELISA, the low-molecular-weight substances of BMDA (FMJ-GO) and its derivative DMMA (FMJ-G4) of this invention inhibited the production of TNF-α and IL-1β inflammatory cytokines. Figure 2 C) indicates that these low molecular weight compounds also inhibited the activity of the NF-κB transcription factor and suppressed NF-κB expression and nuclear translocation. Figure 2 D).
[0077] 2. Evaluation of the anti-inflammatory efficacy of BMDA (FMJ-G0) and its derivatives (DMMA, FMJ-G4) in a DNBS-induced colitis model.
[0078] For experimental colitis, male SD rats (250-260g) were fasted the day before the onset of colitis. A water bottle was provided, allowing them to drink only water. Then, after anesthesia, a rubber cannula was inserted into the anus, and a substance obtained by dissolving 48.0 mg of DNBS in 0.4 mL of 50% ethanol was injected through the cannula. This procedure was repeated for 3 days.
[0079] Starting on day 4 after DNBS insertion, BMDA (FMJ-G0) and its derivatives (DMMA, FMJ-G4) were diluted with PBS and injected 500 μL rectally at a concentration of 200 μg / mL after anesthesia. This procedure was repeated for 5 days. As a control group, DMSO was diluted with PBS at the same ratio and injected for the same 5 days. Then, on day 6, the rats were asphyxiated, their large intestines were removed, and the degree of colitis was assessed according to known methods.
[0080] In addition, a portion of the large intestine was taken out and placed in cell lysis buffer (20mM Tris-HCl [pH 7.5], 150mM NaCl, 1mM EDTA, 1% Triton X-100, 0.5% SDS) for sonication. Then, it was separated by centrifugation, and only the supernatant was collected. After quantifying the protein, it was subjected to immunoblotting.
[0081] Then, a portion of the supernatant prepared for immunoblotting after centrifugation was used to measure the level of chemokine CINC-3 (cytokine-induced neutrophil chemoattractant) by ELISA. Additionally, to determine the activity of macrophages introduced into the distal colon, the titer of MPO (myeloperoxidase) was measured. The distal colon fragment was pulverized in an ultrasonic grinder, centrifuged, and hydrogen peroxide was added to the supernatant for decomposition. The change in absorbance was measured at 460 nm for 1 minute.
[0082] See results Figure 3 A-3B, BMDA (FMJ-G0) and its derivative DMMA (FMJ-G4) low molecular weight substances significantly reduced the inflammatory response induced by DNBS to meaningful levels.
[0083] Compared to the large intestine, treatment with DNBS+PBS showed that the large intestine became significantly shorter and the ulcer crusts were considerably larger. Figure 3 (A-3B). However, it can be seen that the large intestine length of rats treated with DMMA (FMJ-G4) was longer than that of the group treated with DNBS+PBS, and the ulcer-induced crusts were smaller. Specifically, rats treated with the derivative DMMA (FMJ-G4) showed a slightly longer large intestine length than those treated with BMDA (FMJ-G0), and the ulcer crusts were also smaller. The large intestine length of rats treated with BMDA (FMJ-G0) did not differ significantly from that of the group treated with DNBS+PBS, but showed a marked improvement in ulcer severity. However, BMDA (FMJ-G0) and DMMA (FMJ-G4) treatments did not restore the weight loss caused by DNBS treatment. Figure 3 C).
[0084] In addition, the colon of mice administered via enema with low molecular weight BMDA (FMJ-G0) and its derivative DMMA (FMJ-G4) showed lower macrophage peroxidase activity compared to the colon of mice treated with DNBS+PBS. Figure 3 D), and it was observed that the production of the chemokine CNIC-3 introduced into neutrophils was also lower ( Figure 3 E).
[0085] 3. Anti-inflammatory effects of BMDA (FMJ-G0) and its derivatives (DMMA, FMJ-G4) in a type 2 bovine collagen-induced rheumatoid arthritis model.
[0086] Rheumatoid arthritis was induced in 7-week-old male DBA / J1 mice. Type II collagen (2 mg / mL) was completely mixed with CFA (Complete Freund's Adjuvant) at a 1:1 ratio, and 0.1 mL (100 μg) of the mixture was injected intradermally 2 cm from the tail base. Two weeks later, IFA was used instead of CFA, and mixed uniformly with type II collagen at a 1:1 ratio. The same amount and volume as the first injection were injected subcutaneously at the tail base. Three days later, the mice were divided into four groups for a second injection.
[0087] In addition, male mice were orally administered BMDA (FMJ-G0) and its derivatives (DMMA, FMJ-G4) at a concentration of 2.5 mg / mL for 21 days in a volume of 200 μL (20 mg / kg body weight), and then the control group was orally administered soybean oil.
[0088] During the experiment, the dorsum of the forelimbs and hindlimbs was measured three times a week using calipers. The participants were then subjected to asphyxiation to prepare joint sites for immunohistochemical staining and Western blotting. Additionally, the spleen was removed and its size was compared. Serum was prepared by drawing blood from the portal vein. The specific methods are as follows.
[0089] 1) Prepare paraffin sections, including those from the ankle joint of the forelimb. First, decalcify the sections, then stain them with H&E at a thickness of 4 μm.
[0090] 2) Add cell lysis buffer and use an ultrasonic homogenizer to homogenize the tissue to prepare for immunoblotting.
[0091] 3) After adding trisol solution to the joint tissue, the tissue was pulverized with an ultrasonic grinder. After centrifugation, the proteins and DNA precipitated by the trisol solution were separated by centrifugation. Then, total RNA was recovered from the supernatant, and c-DNA was synthesized using oligo-dT primers and reverse transcriptase. Quantitative qRT-PCR and immunoblotting were attempted.
[0092] See results Figure 4 Mice A-4B, compared to the control group treated with soybean oil, showed significantly lower paw swelling when orally administered BMDA (FMJ-G0) and DMMA (FMJ-G4). Oral administration of BMDA (FMJ-G0) and DMMA (FMJ-G4) did not reverse collagen-induced rheumatoid arthritis-induced weight loss. Figure 4 B), but compared with the control group, the spleen length of mice treated with BMDA (FMJ-G0) and DMMA (FMJ-G4) was smaller and the weight was also reduced. Figure 4 C-4D).
[0093] In addition, observe Figure 5 In rats A-5B, severe inflammation and synovitis were observed after oral administration of soybean oil following collagen induction and investigation of joint tissue staining. However, these inflammations and synovitis were significantly reduced upon oral administration of BMDA (FMJ-G0) and DMMA (FMJ-G4). In particular, a significant reduction in inflammation was observed upon oral administration of BMDA (FMJ-G0).
[0094] In addition, when the expression of inflammatory cytokines in the joint region was investigated by qRT-PCR, low levels of the inflammatory cytokines TNF-α, IL-1β, and IL-6 were also observed in the spleen of mice treated with soybean oil. Figure 6 A). Conversely, in the joint sites of animals orally administered BMDA (FMJ-G0) and DMMA (FMJ-G4), the expression of two proteins involved in antioxidant responses, HO-1 and Nrf2, was increased. Figure 6 B).
[0095] In particular, by showing enzyme activities similar to those in the serum of untreated control mice, it was confirmed that oral administration of BMDA (FMJ-G0) and DMMA (FMJ-G4) for 3 weeks did not increase the activities of AST and ALT enzymes, which are indicators of hepatotoxicity (see [link to original text]). Figure 7 ).
[0096] <Example 3: Synthesis of BMDA(FMJ-GO) Derivatives and Evaluation of Their Anti-inflammatory Effects>
[0097] Except for changing the reaction materials in Example 1 above, benzyl-decyl-ethyl-amine (FMJ-G1), benzyl-dodecyl-methyl-amine (FMJ-G2), and decyl-4-fluoro-benzyl-methyl-amine (FMJ-G3) derivatives of FMJ-G0 were synthesized by the same method.
[0098] Specifically, the FMJ-G1 derivative was synthesized by mixing N-benzylethylamine and decanal at a concentration of 1 M; the FMJ-G2 derivative was synthesized by mixing N-benzylmethylamine and dodecanal; and the FMJ-G3 derivative was synthesized by mixing 1-(4-fluorophenyl)-N-methylmethanamine and decanal in methanol, via reductive amination. The synthesized substances were then purified by column chromatography. The chemical structures of the synthesized substances are represented by formulas 1-3 to 1-5. (See...) Figure 8 A)
[0099] [Chemical Formulas 1-3]
[0100]
[0101] [Chemical Formulas 1-4]
[0102]
[0103] [Chemical Formulas 1-5]
[0104]
[0105] Then, THP-1 cell lines were pretreated with FMJ-G0 derivatives FMJ-G1, FMJ-G2, and FMJ-G3 at a concentration of 4 μm for 1 hour, followed by culturing for 4 hours with lipopolysaccharide (1 μg / mL). The cell lines were immediately recovered, and the signaling pathways involved in the synthesis of inflammatory cytokines were identified. The results are presented in [Table data would be inserted here]. Figure 8 B.
[0106] The results confirmed that pretreatment with FMJ-G1, FMJ-G2, and FMJ-G3 inhibited the phosphorylation of p38 MAP kinase, JNK, and MK2 by lipopolysaccharide (LPS), and that FMJ-G0 derivatives could suppress the inflammatory response.
[0107] <Example 4: Preparation of cosmetic compositions containing BMDA (FMJ-GO) and its derivatives and evaluation of their efficacy in improving atopic dermatitis>
[0108] 1. Preparation of cosmetic compositions
[0109] Add 0.3g of olive wax to 2mL of soybean oil (Sigma-Aldrich) and place it in a 15ml glass tube. Then, place the tube in a 75°C water bath and vortex every 10 minutes while boiling for 30 minutes to melt the olive wax. Under the same conditions, place 7.7ml of purified water in a 75°C water bath and heat for 30 minutes. Then, pour 7.5ml of purified water into the tube containing the olive wax and vortex thoroughly. Next, add 30ug (0.3%) of BMDA and its derivatives (FMJ-G0, FMJ-G4, FMJ-G1, FMJ-G2, FMJ-G3) synthesized in Examples 1 and 3, mix thoroughly, and cool on ice to prepare a cosmetic cream.
[0110] 2. Evaluation of efficacy in improving atopic dermatitis
[0111] To induce atopic dermatitis in 5-week-old Balb / C mice, the fur on the backs of the mice was shaved. One day later, a 0.5% solution of DNCB (2,4-dinitrochlorobenzne) was prepared by adding it to a solution of acetone and olive oil (3:1). 150 μL was applied each time for 3 consecutive days. Then, the same concentration was applied twice a week to the shaved backs for two weeks. On the other hand, to alleviate the induced atopic dermatitis, a cosmetic cream containing BMDA (FMJ-G0) and its derivatives (FMJ-G4, FMJ-G1, FMJ-G2, FMJ-G3) of the present invention was applied to the backs of the mice with induced atopic dermatitis for 2 weeks, and changes in skin inflammation were observed.
[0112] As a result, Figure 9 As shown in Figure A, cosmetic creams containing BMDA (FMJ-G0) and DMMA (FMJ-G4) significantly reduced DNCB-induced atopic dermatitis, and regrowth of hair was also observed on the relieved skin. Additionally, from... Figure 9 B. It was observed that in DNCB-induced acute atopic dermatitis, immune cells were activated and the spleen appeared enlarged. However, the spleen size of mice with skin treated with a cosmetic cream containing BMDA (FMJ-G0) and DMMA (FMJ-G4) was similar to that of mice without induced atopic dermatitis. Furthermore, the size of the inguinal lymph nodes was also similar to that of the spleen.
[0113] In addition, under the same conditions, a commercially available steroid ointment (Lidomax) (0.15%) was applied to the skin, and the results confirmed similarities in dermatitis severity, spleen size, and lymph node size to those of the control group (vehicle) which showed similarities to those of the cosmetic cream without the active ingredient. Figure 9 AB).
[0114] in addition, Figure 9 Figure C shows the results of applying a cosmetic cream containing the derivative synthesized in Example 3. Figure 9 C. It was observed that application of FMJ-G1 and FMJ-G3 cosmetic creams significantly alleviated atopic dermatitis. However, as with the control group (Vehicle), treatment with FMJ-G2 cosmetic cream did not prevent the progression of acute dermatitis induced by DNCB. These results are clearly closely related to the size of the spleen and lymphatic fluid. That is, from... Figure 9 D confirmed that the spleen and lymph nodes of mice treated with cosmetic cream containing FMJ-G2 increased in size in the same way as those of mice treated with the control group (Vehicle).
[0115] Figure 10 A and Figure 10 B showed that applying BMDA (FMJ-G0) and DMMA (FMJ-G4) to the skin significantly prevented acute dermatitis caused by DNCB and significantly reduced dermal thickness.
[0116] Figure 10 The results of A and B are as follows: Figure 9 As shown, skin tissue was excised from the back of mice in the group, fixed in 10% formaldehyde for 48 hours, paraffin slides were prepared, and then thinned to a thickness of 4 μm. After preparation of thin slides, hematoxylin-eosin staining was performed. Then, the results of whether the damaged skin tissue could be restored by BMDA (FMJ-G0) and DMMA (FMJ-G4) were investigated using an optical microscope equipped with the Leica application (Leica Microsystems, Swistzerland).
[0117] Treatment with BMDA or DMMA (FMJ-G0 / G4) confirmed that inflammation caused by DNCB thinning of the dermis. The dermis is... Figure 10 In photo A, from top to bottom, the first dark purple layer is the epidermis, the pink layer below it is the dermis, the dark layer below that is the subcutaneous layer, and below that is what is equivalent to muscle.
[0118] Figure 10C shows that toluidine blue staining of BMDA (FMJ-G0) and DMMA (FMJ-G4) prevents mast cells from invading the dermis, thereby inhibiting the inflammatory response in the dermis. Figure 10 C is obtained by using toluidine blue solution to... Figure 10 After staining a portion of the thin section prepared in AB, the results of mast cells invading the dermis were observed using an optical microscope according to the described method. By preventing mast cells from invading the dermis, inflammation in the dermis is protected from mast cells.
[0119] Figure 10 D showed that mice treated with BMDA (FMJ-G0) and DMMA (FMJ-G4) had significantly lower concentrations of IgE in their blood, which is closely related to allergic reactions, compared with the control group. Figure 10 D is in Figure 9 Atopic dermatitis was induced by treating mice with BMDA (FMJ-G0) and DMMA (FMJ-G4). Two weeks later, blood (500 μL) was collected from the hepatic veins of mice in each group and kept at room temperature for 30 minutes. The blood was then centrifuged to separate the serum. The serum was then used to measure the IgE concentration associated with the allergic reaction by ELISA.
[0120] Anti-mouse IgE (Pharmingen, CA, USA) was diluted with PBS (pH 7.4) in 96-well plates, with 100 μL coating each well. The plates were then incubated at 4°C for 12 hours. After washing the plates with PBS containing 0.05% Tween, they were blocked with PBS containing 1% BSA, 5% sucrose, and 0.05% NaN3 for 1 hour. After washing several times with washing buffer, recombinant IgE and serum were added, and the mixture was incubated at 37°C for 2 hours. The plates were then washed again, followed by the addition of biotinylated IgE (Pharmingen, CA, USA), and incubation for another 2 hours. After washing the plates, avidin peroxidase was added, and the mixture was incubated at 37°C for 30 minutes. After washing the plates again, ABTS solution was added as a substrate, and the absorbance was measured at 405 nm using an ELISA reader (Epoch2, BioTek, VT, USA). The results indicate that treatment with BMDA or DMMA (FMJ-G0 / G4) also inhibited IgE production associated with allergic reactions.
[0121] Figure 11 Is it like this? Figure 9 After inducing atopic dermatitis, mice were treated with BMDA (FMJ-G0) and DMMA (FMJ-G4). After two weeks, a portion of skin tissue from each group of mice was placed in a trisol solution and centrifuged using an ultrasonic homogenizer. To separate total RNA, proteins and DNA were precipitated in the trisol solution and centrifuged. Total RNA was then recovered from the supernatant, and c-DNA was synthesized using oligo-dT primers and reverse transcriptase. Quantitative data of TNF-α, IL-1β, IL-6, iNOS, and Cox2 transcription levels were obtained by qRT-PCR.
[0122] In the control group skin treated with DNCB, the amounts of transcripts of inflammatory cytokines TNF-α, IL-1β, and IL-6, as well as proteins iNOS and COX2 that produce inflammatory mediators (NO, PDE2), were dramatically increased. Furthermore, treatment with BMDA (FMJ-G0) and DMMA (FMJ-G4) significantly reduced the amounts of these transcripts. Figure 11 AC).
[0123] When the activity of signaling proteins affecting the transcription of these proteins was investigated by immunoblotting, as supporting the previous results, BMDA (FMJ-G0) and DMMA (FMJ-G4) treatments significantly reduced the phosphorylation levels of inflammation-related JNK, p38MAPK, and NF-κB compared to the control group.
