[0132] Isolation of cis-4-hydroxycinnamyl 4-hydroxybenzoate, a novel compound, from carrots
[0133] <1-1> Preparation of Carrot Methanol Extract
[0134] After crushing Jeju carrots, methanol extraction was performed. 7.0 L of methanol was added to 1 kg of crushed carrots to obtain a methanol extract, which was then concentrated, mixed with water, and the methanol was evaporated.
[0136] <1-2> Preparation of Ethyl Acetate Fraction
[0137] An ethyl acetate extract was obtained by adding an equal amount of ethyl acetate (EA) to the water fraction from which methanol had been evaporated. The EA extract was concentrated and then solubilized with methanol for use in the following examples.
[0139] <1-3> Silica Gel Column Chromatography
[0140] After concentrating the methanol fraction, it was loaded onto a column (30×450 mm) packed with silica gel 60 resin (MERCK, Darmstadt, Germany), and five fractions (fractions 1, 2, 3, 4, and 5) were obtained by silica gel chromatography using chloroform:methanol (10:1, v / v) as the elution solvent. As a result of investigating the anti-inflammatory activity of the five fractions, fraction 4 showed an anti-inflammatory effect and was concentrated to be used as a sample for secondary fractionation. [Figure 2] is a diagram showing the evaluation of samples fractions 1 to 5 separated by silica gel column chromatography using TLC (Thin layer chromatography). After concentrating the sample fraction 4 showing anti-inflammatory activity, it was used in the next step <1-4>.
[0142] <1-4> Flash Chromatography
[0143] Fraction sample No. 4 obtained in the above Examples <1-3> was loaded into a flash chromatograph and flash chromatography was performed using methanol as the elution solvent. Flash chromatography analysis was performed using a Biotage Isolera Spektra One MPLC (Biotage, uppsala, Sweden). Through this, the anticancer and anti-inflammatory activities of fraction sample No. 1 were evaluated, and [Figure 3] shows the results of evaluation using MPLC and TLC (Thin layer chromatography) on fractions 1, 2, and 3.
[0145] <1-5> HPLC (High performance liquid chromatography)
[0146] Substance No. 1 obtained through the flash chromatography above was injected into preparatory high-performance liquid chromatography (prep HPLC). HPLC analysis was performed using an Agilent HPLC (Agilent, Santa Clara, California, USA). HPLC separation was performed using an ODS (10×250 mm) C18 column, and the separated substances were sieved through a 0.2 μm filter. The injection volume was 0.5 mL, the flow rate was 5 mL / min, and the column temperature at 254 and 365 nm was room temperature. The mobile phase consisted of water (solvent A) and methanol (solvent B). For gradient elution, solvent B was initially set to 50% and increased to 100% at 23 minutes. The peak of the final separated and purified active compound was indicated at 14.343 minutes. [Figure 4] is a diagram showing the HPLC results and the final separated fractions evaluated using TLC (Thin layer chromatography).
[0148] Identification of the novel compound cis-4-hydroxycinnamyl 4-hydroxybenzoate
[0149] <2-1> Analysis of Carrot-Derived Natural Products
[0150] A putative identification analysis of metabolites using Progenesis QI was performed using the natural product cis-4-hydroxycinnamyl 4-hydroxybenzoate isolated from the carrot methanol extract through the above <Example 1>.
[0151] Specifically, in the metabolite analysis workflow using Progenesis QI, Lysophospholipid PC (16:0 / 0:0) was used as a representative example in ESI(+) mode. First, the adductors generated after deconvolution were identified, and the reliability of candidate substances was evaluated by analyzing isotopic similarity and chromatograms. Additionally, the structures of the fragment ions generated through MS / MS analysis were assigned by comparing them with a database, and specific compounds were identified by comparing the UPLC-MRM chromatograms of the carrot extract and the standard substances. Finally, it was confirmed whether the substance detected in the carrot was identical to the standard substances by comparing MS / MS spectra (Figs. 5a–8c).
[0152] In addition, to analyze the structure of the finally isolated and purified active compound, the structure was identified through NMR (nuclear magnetic resonance) analysis, and the molecular weight was measured using an ESI-Mass spectrometer and confirmed to be 270 g / mol. Through this, it was confirmed that one of the novel compounds purified from the Jeju carrot of the present invention is cis-4-hydroxycinnamyl 4-hydroxybenzoate (Chemical Formula 1).
[0153] [Chemical Formula 1]
[0154]
[0156] <2-2> Metabolite Analysis of Natural Products Derived from Jeju Carrots and Identification of Novel Compounds
[0157] A novel compound, 3-(4-hydroxyphenyl)propyl 4-hydroxybenzoate (Chemical Formula 2), was synthesized, which can exhibit activity similar to that of the natural product cis-4-hydroxycinnamyl 4-hydroxybenzoate isolated from carrot methanol extract.
[0158] [Chemical Formula 2]
[0159]
[0161] In the metabolite analysis workflow using Progenesis QI, metabolites were identified using caffeic acid in ESI(-) mode and falcarindiol in ESI(+) mode as representative examples. First, the adducts generated after deconvolution were identified, and reliability was evaluated by analyzing isotopic similarity and chromatograms. Subsequently, structures were assigned by comparing MS / MS fragment ions with a database. In addition, for falcarindiol, an in-house database was utilized to enhance analytical reliability. Subsequently, Nuclear Magnetic Resonance (NMR) analysis was performed to identify the structure of the synthesized compound, and the molecular weight was measured using an ESI-Mass spectrometer, confirming that the compound was 272 g / mol. Through this, it was finally confirmed that the novel compound purified from Jeju carrots in this study is 3-(4-hydroxyphenyl)propyl 4-hydroxybenzoate (Figs. 9a–9c).
[0163] Anti-arthritic effect of carrot extract or fractions thereof
[0164] <3-1> Analysis of MTT cell viability
[0165] Primary cultured chondrocytes were exposed to various concentrations of cis-4-hydroxycinnamyl 4-hydroxybenzoate (0–20 μM). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed 24 hours after treatment. Briefly, primary cultured chondrocytes (5×10⁶) 4) was seeded into a 96-well plate. After 24 hours of incubation, cis-4-hydroxycinnamyl 4-hydroxybenzoate (0–20 μM) was added to the cells. MTT solution was added to each well for 4 hours at the final incubation time. After adding 100 μL of dimethyl sulfoxide solution, optical density was recorded using a microplate reader (570 nm).
[0166] When mouse primary chondrocytes were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate (0, 5, 10, 20 uM), no toxicity was observed in the chondrocytes.
[0168] <3-2> Efficacy Verification via Reverse Transcription-Polymerase Chain Reaction (RT-PCR) Analysis
[0169] Chondrocytes were isolated from the femoral condyle and tibial plateau of 4-day-old mice (n = 8) by digesting cartilage tissue with DMEM supplemented with 0.2% collagenase (Sigma). Passage "0" (P0) primary chondrocytes (3 x 10⁶ 530mm culture dishes were maintained as a monolayer in DMEM (Gibco, Waltham, MA, USA) supplemented with 10% fetal bovine serum and antibiotics (100 units / ml). Penicillin G and 100 μg / mL streptomycin (Gibco, Waltham, MA, USA) were treated for 24 hours in a 5% CO2 incubator at 37°C. Then, chondrocytes were exposed to various concentrations of cis-4-hydroxycinnamyl 4-hydroxybenzoate (0–20 μM) in the absence or presence of IL-1β (1 ng / mL), IL-6 (100 ng / mL), TNF-α (10 ng / mL), or LPS (10 ng / mL). Total RNA was extracted from primary cultured chondrocytes using the TRIzol reagent (Molecular Research Center, Inc., Cincinnati, OH, USA). The quality and concentration of RNA were evaluated using a NanoDrop™2000 spectrophotometer (Thermo Scientific, Waltham, MA, USA). RNA was reverse transcribed, and the resulting cDNA was amplified by PCR. mRNA expression was evaluated using the SYBR premixed Extaq reagent (Takara Bio, Mountain View, CA, USA), and glyceraldehyde-3-phosphate dehydrogenase (Gapdh) was used as an internal control. It was confirmed that carrot samples (0, 5, 10, 20 uM) inhibit the transcription of catabolic factors (Mmp3, Mmp13, Adamts 4, Adamts 5) induced by inflammatory cytokines IL-1β (1 ng / ml), TNF-α (10 ng / ml), and IL-6 (100 ng / ml). It was also confirmed that they inhibit the transcription of catabolic factors (Mmp3, Mmp13, Adamts 4, Adamts 5) induced by LPS (10 ng / ml).In addition, quantitative analysis of transcription factors also showed that IL-1β inhibited the expression of Mmp3 and Mmp13, and TNF-α inhibited the expression of Mmp3, Mmp13, Adamts4, and Adamts5 (Fig. 10a, Fig. 10b).
[0171] <3-3> Analysis of WST cell viability using chondrocytes
[0172] Anti-aging activity was confirmed by treating human chondrocyte cell line C20A4 with cis-4-hydroxycinnamyl 4-hydroxybenzoate.
[0173] Specifically, to induce senescent cells of the chondrocyte cell line, the cells were cultured for a total of 6 days, and a low concentration of 25 nM of doxorubicin was used as the drug to induce senescence.
[0174] As a result, cis-4-hydroxycinnamyl 4-hydroxybenzoate showed no activity in normal chondrocytes, whereas activity was confirmed in aged chondrocytes. In other words, it was confirmed that cis-4-hydroxycinnamyl 4-hydroxybenzoate inhibits the survival of chondrogenic cells (Fig. 11 AB).
[0176] <3-4> SA-β-galactosidase staining
[0177] The effect was confirmed using SA-β-galactosidase staining, a well-defined biomarker for cellular senescence. After preparing senescent cell lines using the same method as in Example <3-3> above, staining was performed using the Senescence β-Galactosidase Staining Kit (Cell Signaling Technology, #9860). As a result, it was confirmed that the SA-β-galactosidase staining area was reduced in the region treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate compared to the control group.
[0179] <3-5> RT-qPCR
[0180] To compare the expression of aging-related genes, messenger RNA expression was compared using a real-time gene amplifier. C20A4 cells were seeded into 6-well plates and cultured for 1 day. Cells were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate for 24 hours. Total RNA was purified according to the manufacturer's protocol using the TaKaRa MiniBEST RNA Extraction Kit (TaKaRa, Kyoto, Japan). Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed using RNA-direct™SYBR® Green Realtime qPCR Master Mix (Enzynomics, Daejeon, Korea). The RT-qPCR mixture contained 10 μL of SYBR Green Realtime qPCR Master Mix, 1 μL of enzyme, 1 μL of template RNA (100 ng / μL), 1 μL of specific primer-F (10 pmol / μL), 1 μL of specific primer-R (10 pmol / μL), and 6 μL of nuclease-free H2O. The primers used for RT-PCR were purchased from Bionia (Daejeon, Korea).
[0181] As a result, it was confirmed that the expression of aging-related genes tended to decrease compared to the control group when treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate. In addition, when cytokine changes were examined, changes in IL-1b, IL-6, and MMP9 were observed (Fig. 12 A).
[0183] <3-6> Histogram Analysis of uPAR(CD87)
[0184] uPAR is a factor involved in cell motility and survival, and can be affected by changes in the microenvironment associated with aging. To analyze uPAR (CD87) expression in C20A4 cells, cells were stained and fluorescence signals were measured using FACS (BD, Flow Cytometry). Cells were stained with uPAR antibodies, and expression levels were quantitatively evaluated via FACS. The analysis results showed that uPAR expression tended to increase in aged cells, and decreased when treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate (Fig. 12 B).
[0186] <3-7> Analysis of ROS Generation and Mitochondrial ROS Fluorescence Expression via Fluorescence Microscopy
[0187] ROX Green and MitoSOX staining were performed to evaluate the effects of drug A on aged C20A4 cells. After treating cells with cis-4-hydroxycinnamyl 4-hydroxybenzoate, ROX Green was used to check for the production of ROS (reactive oxygen species), and MitoSOX was used to measure oxidative stress within mitochondria. Changes were observed using a fluorescence microscope after fluorescence staining.
[0188] As a result, ROS and mitochondrial stress levels were significantly reduced in the cis-4-hydroxycinnamyl 4-hydroxybenzoate-treated group (Fig. 13).
[0190] <3-8> Immunoblot Analysis
[0191] After harvesting the cells, they were lysed using radioimmunoprecipitation assay buffer (Thermo Fisher Scientific, Waltham, MA, USA). Each sample was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and then electrotransferred onto an Immobilin-FL polyvinylidene fluoride (PVDF) membrane (Millipore, Burlington, MA, USA). After blocking with Odyssey® Blocking Buffer (LI-COR, Lincoln, NE, USA) for 1 hour, the blots were incubated overnight with the primary antibody at 4°C. After washing, the blots were incubated for 60 minutes with IRDye 680- and IRDye 800-labeled secondary antibodies diluted with Odyssey blocking buffer containing 0.2% Tween-20 / 0.01% sodium dodecyl sulfate. Protein bands were detected using an Odyssey CLx imaging machine (LI-COR).
[0192] In this invention, changes in the expression of proteins p65, pERK, ERK, pSTAT3, p-p38, and LC3 were confirmed using Western blot analysis. The experiment was conducted using β-actin as an internal control, and protein expression was compared relatively. As a result of the experiment, the protein expression of p65, pERK, and LC3 changed significantly. The increased expression of p65 and pERK suggests the activation of specific signaling pathways, which may be related to inflammatory responses and intracellular signaling. On the other hand, changes in LC3 expression suggest the possibility of being related to the regulation of the autophagy process. These results provide evidence that HA influences specific signaling pathways and autophagy mechanisms (Fig. 14 A).
[0194] <3-9> Analysis of Intracellular Mitochondria Metabolism
[0195] The Seahorse kit was used to analyze intracellular mitochondrial metabolism. Oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) were measured through experiments. After culturing cells under appropriate conditions, mitochondrial respiration and glycolysis activities were evaluated using the Seahorse analyzer.
[0196] As a result, significant changes in OCR and ECAR were observed under specific conditions affecting mitochondrial function and energy metabolism. This suggests that mitochondrial metabolism can be regulated by changes in cellular state and the environment.
[0198] Antioxidant and anti-inflammatory effects of carrot extract or fractions thereof
[0199] <4-1> Cell Line and Culture Conditions
[0200] RAW 264.7 macrophage cells were purchased from the Korean Cell Line Bank (Seoul, Korea). Macrophage cells were cultured in high-glucose Dulbecco modified Eagle medium (DMEM) supplemented with 10% fetal bovine serum (Hyclone, Logan, UT, USA) and 1% penicillin / streptomycin (Hyclone). Cells were cultured at 37°C under a 5% CO2 atmosphere.
[0202] <4-2> Cell Proliferation
[0203] RAW 264.7 cells (3×10⁶ 6Canine cells / plates were seeded into 96-well plates and cultured for 1 day. Cells were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate for 1 day. Cell viability was assessed using CellTiter 96 AQueous One Solution (Promega, Madison, WI, USA). After mixing the culture medium and aqueous solution in a 5:1 ratio, 100 μL was added to a 96-well plate and incubated at 37°C for 2 hours. Absorbance was estimated at OD490 using a Molecular Devices (SPECTRAMAX ID5) reader.
[0205] <4-3> Analysis of Iron-Reducing Antioxidant Capacity (FRAP)
[0206] The FRAP working solution was prepared as a solution (300 mM sodium acetate buffer + 10 mM TPTZ + 20 mM FeCl3 = 10:1:1). After adding 150 μl of the FRAP working solution and 50 μl of the extract, the reaction was carried out at 37°C for 30 minutes. The absorbance was measured at 593 nm using a microplate reader. A standard curve was constructed based on the FeSO4 value. As a result, it was confirmed that it possesses excellent iron-reducing antioxidant activity similar to that of FeSO4, which was used as a standard (Fig. 15 B).
[0208] <4-4> Analysis of Trolox Equivalent Antioxidant Capacity (TEAC)
[0209] Free radical scavenging activity was investigated using the Trolox Equivalent Antioxidant Dose (TEAC). For the reaction with the ABTS solution, 2,2-azino-bis-(3-ethylbenzo-thiazolin-6-sulfonic acid) and 2.45 mM potassium persulfate were mixed. They were reacted for 18 hours. Subsequently, 180 µl of the ABTS solution was mixed with 20 µl of cis-4-hydroxycinnamyl 4-hydroxybenzoate and reacted for 5 minutes. After the reaction, samples were measured at 734 nm. A standard curve was constructed by adding Trolox.
[0210] As a result, radical cations were generated by the antioxidants of cis-4-hydroxycinnamyl 4-hydroxybenzoate, and the color changed to blue-green. In addition, the results of Trolox and Ascorbic acid were presented as positive controls for comparison.
[0211] As a result, superior antioxidant inhibitory efficacy compared to the two substances used as positive controls was confirmed (Fig. 15 B).
[0213] <4-5> NO Analysis
[0214] Nitric oxide (NO) is a biological mediator produced by LPS-stimulated macrophages. We intended to evaluate the inhibitory effect of cis-4-hydroxycinnamyl 4-hydroxybenzoate on NO production induced by LPS (lipopolysaccharide from E. coli O111:B4; InvivoGen, San Diego, CA, USA) in RAW 264.7 cells.
[0215] Specifically, RAW 264.7 cells (3×10⁶ 6Canine cells (or plates) were seeded into a 96-well plate and cultured for 1 day. Cells were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate along with LPS (1 μg / mL) for 24 hours for 1 day. NO measurements were evaluated in the supernatant culture medium using the NO Plus detection kit (iNtRON Biotechnology, Gyeonggi, Korea). A pre-reaction was induced by adding 50 μL of N1 buffer (sulfanilamide in the buffer) to each well of the 96-well plate with 100 μL of culture medium or nitrite standard. Then, after incubating the 96-well plate for 20 minutes, the mixture was reacted with 50 μL of N2 buffer (naphthyl-ethylenediamine in the buffer). After incubating the mixture for 10 minutes, NO formation was measured by the absorbance value at OD560 nm using Molecular Devices (SPECTRAMAX ID5).
[0216] As a result, LPS stimulation induced an increase in NO concentration, whereas the cis-4-hydroxycinnamyl 4-hydroxybenzoate treated sample group showed a concentration-dependent decrease compared to the LPS-treated control group. Therefore, it was found that NO production is induced by LPS, and cis-4-hydroxycinnamyl 4-hydroxybenzoate reduces LPS-induced NO production (Fig. 16 A).
[0218] <4-6> RT-qPCR
[0219] RAW 264.7 cells (3×10⁶ 6Canine cells (or plates) were seeded into 96-well plates and cultured for 1 day. Cells were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate in combination with LPS (1 μg / mL) for 24 hours. Total RNA was purified according to the manufacturer's protocol using the TaKaRa MiniBEST RNA Extraction Kit (TaKaRa, Kyoto, Japan). Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed using RNA-direct™ SYBR® Green Realtime qPCR Master Mix (Enzynomics, Daejeon, Korea). The RT-qPCR mixture contained 10 μL of SYBR Green Realtime qPCR Master Mix, 1 μL of enzyme, 1 μL of template RNA (100 ng / μL), 1 μL of specific primer-F (10 pmol / μL), 1 μL of specific primer-R (10 pmol / μL), and 6 μL of nuclease-free H2O. The primers used for RT-PCR were purchased from Bionia (Daejeon, Korea).
[0220] As a result, as shown in [Fig. 16] B, LPS-stimulated RAW 264.7 cells showed increased iNOS protein expression, whereas cis-4-hydroxycinnamyl 4-hydroxybenzoate highly inhibited it. Additionally, analysis of iNOS transcription levels in RAW264.7 cells revealed that LPS increased iNOS transcript levels, whereas cis-4-hydroxycinnamyl 4-hydroxybenzoate decreased the increased transcript levels of iNOS, TNF-α, and IL-1β (Fig. 16 A, Fig. 17 A).
[0222] <4-7> ELISA
[0223] The secretion amounts of IL-1β and TNF-α were quantified using an ELISA (enzyme-linked immunosorbent assay) kit from BioLegend. After collecting the cell culture supernatant, an ELISA was performed according to the manufacturer's protocol, and the absorbance was measured at 450 nm.
[0224] As a result, while the LPS-treated group showed high secretion levels, the production of IL-1β and TNF-α tended to decrease in a concentration-dependent manner following HA treatment. This suggests that HA regulates the expression of inflammatory cytokines (Fig. 17 B).
[0226] <4-8> Immunoblot Analysis
[0227] Cells were harvested and lysed using radioimmunoprecipitation assay buffer (Thermo Fisher Scientific, Waltham, MA, USA). Each sample was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and electrotransferred onto an Immobilin-FL polyvinylidene fluoride (PVDF) membrane (Millipore, Burlington, MA, USA). After blocking with Odyssey® Blocking Buffer (LI-COR, Lincoln, NE, USA) for 1 hour, the blots were incubated overnight with the primary antibody at 4°C. After washing, the blots were incubated for 60 minutes with IRDye 680- and IRDye 800-labeled secondary antibodies diluted with Odyssey blocking buffer containing 0.2% Tween-20 / 0.01% sodium dodecyl sulfate. Protein bands were detected using an Odyssey CLx imaging machine (LI-COR). The primary antibody against iNOS was obtained from Cell Signaling Technology (Beverly, MA, USA). And β-actin was purchased from Santa Cruz Biotechnology, Inc (Dallas, TX, USA).
[0228] As a result, as shown in Fig. 16, C, it was confirmed that while iNOS protein expression was increased in LPS-stimulated RAW 264.7 cells, cis-4-hydroxycinnamyl 4-hydroxybenzoate inhibited NO production through the downregulation of iNOS. While the levels of pERK1 / 2 and pJNK were increased by LPS stimulation, they were found to be decreased upon treatment with cis-4-hydroxycinnamyl 4-hydroxybenzoate compared to LPS-stimulated control cells. Therefore, it was confirmed that the inflammatory response in LPS-induced RAW 264.7 cells is suppressed by reducing the levels of pERK and pJNK and inhibiting MAPK signaling. Thus, it was confirmed that the above compounds are associated with the MAPK kinase pathway and that drug action occurs through this signaling system (Fig. 18 A, B).
[0229] In Figure 18, C, the protein expression-inducing effects of HO-1 and NRF2 were analyzed. The Nrf-2 (nuclear factor erythroid-2 like 2; Nfe2I2) and heme oxygenase 1 (HO-1) signaling axis plays a role as a multiorgan protector by reducing oxidative stress in tissue and animal models. Accordingly, Western blot analysis was performed to evaluate whether cis-4-hydroxycinnamyl 4-hydroxybenzoate could induce the Nrf2 / HO-1 signaling axis. Cis-4-hydroxycinnamyl 4-hydroxybenzoate confirmed changes in HO-1 and Nrf2 proteins and altered the expression of Keap1 protein after 3 hours of treatment. Accordingly, it was confirmed that cis-4-hydroxycinnamyl 4-hydroxybenzoate induces protein levels of HO-1 and Nrf2 (Fig. 18 C).
[0231] <4-9> Analysis of ROS Expression via Fluorescence Microscopy
[0232] The effect of HA on LPS-induced ROS (reactive oxygen species) accumulation in RAW264.7 macrophages was evaluated. ROS accumulation was assessed by measuring intracellular ROS concentrations using Invitrogen CellROX® Green Reagent (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's instructions. Cells were pretreated with HA (50 μM) and NAC (1 mM) for 1 hour, followed by treatment with LPS (1 μg / mL) for 1 hour. Subsequently, cells were stained with CellROX green dye at 37°C for 10 minutes. After washing with 1X PBS, the stained ROS were visualized using an automated microscope (Cytation5, Agilent, VT, USA). ROS signals were observed using a fluorescence microscope after fluorescent staining.
[0233] As a result, ROS accumulation tended to decrease in the HA-treated group (Fig. 19). Therefore, it was confirmed that cis-4-hydroxycinnamyl 4-hydroxybenzoate can exert a potent effect as an LPS-induced ROS inhibitor in RAW 264.7 macrophages.
[0235] <4-10> Mouse experiment on foot edema (inflammation)
[0236] The effects of HA were evaluated in a carrageenan-induced foot edema model. Figure 20a A shows representative changes in mouse feet following HA treatment, while Figure 20a B compares relative foot edema thickness. Figure 20a C analyzes DPPH radical scavenging activity and catalase (CAT) activity in mouse liver samples. Figure 20b A confirms TNF-α, IL-1β, and IL-6 protein expression using Western blot, and Figure 20b B analyzes changes in gene expression in HA-treated cells. mRNA levels of TNF-α, IL-1β, and IL-6 were measured using reverse transcription quantitative PCR, and the effect of HA on inflammatory responses was evaluated.
[0237] As a result, the thickness of foot edema was significantly reduced in the HA-treated group, and the protein and mRNA expression of inflammatory cytokines also showed a decreasing trend.
[0239] Anticancer (anti-aging) effects of carrot extract or fractions thereof
[0240] <5-1> Cell Proliferation
[0241] MCF-7, MDA-MB-231 breast cancer cells (1.5×10⁶ 6Canine cells (plates) were seeded into 96-well plates and cultured for 1 day. They were treated for 1 day with cis-4-hydroxycinnamyl 4-hydroxybenzoate and doxorubicin, which is used for aging. Cell viability was tested using CellTiter 96 AQueous One Solution (Promega, Madison, WI, USA). After mixing the culture medium and aqueous solution in a 5:1 ratio, 100 μL was added to a 96-well plate and incubated at 37 °C for 2 hours. Absorbance was estimated at OD490 using a Molecular Devices (SPECTRAMAX ID5) reader. As a result, the concentrations used in the experiment were evaluated as non-toxic (Fig. 21 A).
[0242] The anti-aging activity of cis-4-hydroxycinnamyl 4-hydroxybenzoate was confirmed by treating human breast cancer cell lines MCF-7 and MDA-MD-231. To induce senescent cells in the breast cancer cell lines, the cells were cultured for a total of 6 days, and a low concentration of Doxorubicin 50 nM was used as the senescent agent. While cis-4-hydroxycinnamyl 4-hydroxybenzoate showed no activity in normal breast cancer cells, activity was confirmed in senescent breast cancer cells. As a result, cis-4-hydroxycinnamyl 4-hydroxybenzoate inhibited the survival of senescent breast cancer cells (Fig. 21 A).
[0244] <5-2> SA-β-galactosidase staining
[0245] The effect was confirmed using SA-β-galactosidase staining, a well-defined biomarker for cellular senescence. After preparing an senescent cancer cell line using the same method as in Example <5-1> above, staining was performed using the Senescence β-Galactosidase Staining Kit (Cell Signaling Technology, #9860).
[0246] As a result, it was confirmed that the SA-β-galactosidase staining area was reduced in the area treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate compared to the control group.
[0248] <5-3> RT-qPCR
[0249] MDA-MB-231 cells (5×10⁶ 5Cells / plates were seeded into 6-well plates and cultured with doxorubicin for 6 days. Cells were treated with cis-4-hydroxycinnamyl 4-hydroxybenzoate and DOX (50 nM) for 2 days. Total RNA was purified according to the manufacturer's protocol using the TaKaRa MiniBEST RNA Extraction Kit (TaKaRa, Kyoto, Japan). Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed using RNA-direct™ SYBR® Green Realtime qPCR Master Mix (Enzynomics, Daejeon, Korea). The RT-qPCR mixture contains 10 μL of SYBR Green Realtime qPCR Master Mix, 1 μL of enzyme, 1 μL of template RNA (50 ng / μL), 1 μL of specific primer-F (10 pmol / μL), 1 μL of specific primer-R (10 pmol / μL), and 6 μL of nuclease-free H2O. The primers used for RT-PCR were purchased from Bionia (Daejeon, Korea).
[0250] The effects of cis-4-hydroxycinnamyl 4-hydroxybenzoate on elevated levels of p21, p53, and several aging-related genes at the transcriptional level in breast cancer cells were tested using RT-qPCR.
[0251] As a result, as shown in [Figure 22a], the expression of p21 and p53 genes in senescent breast cancer cells was increased by Doxorubicin treatment, whereas cis-4-hydroxycinnamyl 4-hydroxybenzoate inhibited it. Therefore, it was confirmed that cis-4-hydroxycinnamyl 4-hydroxybenzoate induces apoptosis in senescent cancer cells through the downregulation of p21, p53, and several senescence-related genes.
[0253] <5-4> Immunoblot Analysis
[0254] Normal and senescent cells were harvested and lysed using radioimmunoprecipitation assay buffer (Thermo Fisher Scientific, Waltham, MA, USA). Each sample was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and electrotransferred onto an Immobilin-FL polyvinylidene fluoride (PVDF) membrane (Millipore, Burlington, MA, USA). After blocking with Odyssey® Blocking Buffer (LI-COR, Lincoln, NE, USA) for 1 hour, the blots were incubated overnight with the primary antibody at 4°C. After washing, the blots were incubated for 60 minutes with IRDye 680- and IRDye 800-labeled secondary antibodies diluted with Odyssey blocking buffer containing 0.2% Tween-20 / 0.01% sodium dodecyl sulfate. Protein bands were detected using an Odyssey CLx imaging machine (LI-COR).
[0255] As shown in [Fig. 22b], the expression of pp53, p21, and p16 was significantly increased in senescent cells compared to normal cells. This suggests that cell cycle inhibitory proteins were activated during the aging process and indicates that aging-related signaling pathways were strengthened. On the other hand, the expression of β-actin remained constant compared to the control group, effectively serving as an internal control for the experiment. The present invention suggests that changes in protein expression related to aging are regulated through specific signaling pathways.
[0256] In addition, [Figure 23a] showed that HA reduced the protein levels of YAP1, mTOR, PD-L1, PD-L2, p-AMPK, and GPX4 in a concentration-dependent manner. In particular, the reduction in YAP1 and mTOR implies that HA may influence cell growth and metabolic regulation, while the simultaneous reduction in PD-L1 and PD-L2 suggests the possibility that HA more broadly regulates the effects on immune evasion mechanisms. The reduction in p-AMPK demonstrates the effects of HA on energy homeostasis and metabolic regulatory pathways, and the reduction in GPX4 suggests the possibility that cytoprotective mechanisms related to lipid peroxidation regulation are inhibited. This may imply that HA may also be involved in novel apoptotic pathways such as ferroptosis (iron-dependent cell death).
[0257] Taken together, these results suggest that HA may influence cell growth, metabolism, and immune regulation, as well as antioxidant mechanisms, by regulating specific signaling pathways in senescent cells, and may contribute to the removal of senescent cells by activating apoptotic pathways such as ferroptosis.
[0259] <5-5> Apoptosis assay
[0260] An apoptosis assay was performed using flow cytometry, utilizing BD Biosciences' Accuri™ C6 Plus Flow Cytometer and FITC Annexin V Apoptosis Detection Kit I. After treating cells with HA, the degree of apoptosis was analyzed by performing Annexin V-FITC and PI staining.
[0261] As a result, the proportion of Annexin V-positive (Early Apoptosis) cells significantly increased in the HA-treated group, suggesting that HA has an effect of promoting early apoptosis. On the other hand, the proportion of PI-positive (Necrosis) cells showed a decreasing trend, confirming the possibility that HA influences the induction of programmed cell death rather than late apoptosis (Fig. 23b).
[0263] <5-6> Telomere
[0264] In this invention, telomere length was analyzed using qPCR, and the effects of HA on aged breast cancer cells were confirmed. qPCR was performed using specific primers to measure telomere length, and relative changes were compared based on the telomere length of a negative control group. Experimental results showed that telomere length in aged breast cancer cells decreased significantly to the level of 20–30%, suggesting that telomere shortening occurred during the cellular aging process. However, after treatment with HA, telomere length showed a tendency to increase again, indicating the possibility that HA influences telomere maintenance in aged breast cancer cells. These results suggest that HA can play a role in restoring telomere stability as well as regulating aging-related signaling pathways.
[0266] Evaluation of anti-aging efficacy in human skin cells
[0267] We intended to evaluate the anti-aging efficacy of cis-4-hydroxycinnamyl 4-hydroxybenzoate in UVB-induced aged skin cells.
[0268] After culturing HaCaT cells, bright-field microscopy was performed using an Agilent Cytation 5 instrument to evaluate morphological changes following UVB irradiation and HA treatment. Experiments were conducted by establishing a control group, a UVB-treated group, and UVB and HA (1, 2, 5, 10, 20 μM) treated groups.
[0269] Microscopic analysis revealed that compared to the control group, UVB-treated cells showed increased cell size, changes in morphology, and progression of aging (Fig. 24). In the group treated with HA, a gradual effect was observed starting from 5 μM, and at concentrations of 10 μM and 20 μM, a selective apoptosis effect was observed in aged cells, while non-aged cells were not significantly affected at the same concentrations. These results suggest that HA exhibits an anti-aging effect by selectively killing aged cells, and at high concentrations, it exerts efficacy against aged cells to promote the removal of aged cells.
